Did an oil change and engine makes louds noises

[Delo]

Hi guys this is my first time on this site thought to see if i could seek some help for my problem, I will do my best to explain everything that happened and what i have done so far, im not very mechanically minded but know enough to find my way around the motor , just problem solving is hard from lack of experience.

My car was low on oil but was in need of a change too, i did make the mistake of not flushing the engine the first time. After the oil change i started the car up and it made a few slight tapping sounds nothing to bad from what i could here but it was normally a quiet motor. i thought it would go away soon enough, i drove of up the street maybe 50 ft and tried gonig around the corner and the noise got alot louder before stalling when i tried turning the steering wheel. Then i pushed it home glad was close to home.
The oil i used was 20w/50 and replaced the oil filter too priming it aswell before installing it.

The next day i went out and tried starting it up again to try to find where the noise is coming from with no luck so i turned it off quickly not wanting to do any damage.
I took off the one rocker cover and tried starting it seeing if the oil was circulating and found it was not. So this is where i started to guess the problem either its blocked somewhere in the lines or the oil pump, i was leaning more to just a blockage giving that the car was running perfect before the oil change, after a little reading i found the sump was not an easy task for me to get to the pick up, so decided to go for the oil pump , which i painfully regret what a hassel to get to it only to find i couldnt undo one of the bolts holding the oil pump in. I tried turning the pump myself it looked like it was pumping oil. I know that wouldnt be a good test but all i could do for then,

I end up putting it all back together not being able to check the oil pump, i went and got some diesel to flush the engine, i put a mix of oil 10w/30 and diesel for the flush , and i turned it over without the sparkplugs so it wouldnt fire just using the battery , i was not sure if was safe to run with lack of oil and being diesel im not sure what could hapen. I had a rocker cover off hoping to see the diesel/oil squirt up but nothing come to the top.

This is where im upto at the moment waiting for a friend to bring my battery charger back since i killed mine turning it over.

Any help with where i could go from here would be awesome, money is an issue sort of not being employed at the moment but i need the car going need to get home to brisbane from geelong 20+ hours drive

Sorry its a VS V6 motor too thought i better put that in too just

Oil comes up to the rockers pretty slowly, I wouldnt expect to see it 'squirting' out. I would definitely be looking at taking the sump off and cleaning the pickup.

'Delo' is a brand of oil we use at work....

[moff_man]

pull the filter off and have a look in side it and see if there is any obstructions in the filter or if there is any oil in the filter. its strange it only started doing it after a oil and filter change. and im guessing you put in 4.5L - 4.8L in it (depending on year model). honestly i would just buy a new filter (genuine) and put it on and try and start it. if you get oil up the top end then, problem solverd.

[greenacc]

There's no way i know that draining oil, changing filter and refilling it can block anything. Sounds silly but are you sure you drained the right thing and filled the right place ? ( a guy i know drained his gearbox then filled the engine and stuffed both .
If you didn't do that check the filter as above. maybe put your old filter back on and hope. Even then there's supposed to be a bypass valve to protect the engine if the filter blocks so it should have still worked... good luck man.

[Delo]

Thanks for the quick response guys

@Andrew Yeah i wanted to get to the sump and clean the pickup having no equipment except a few tools and a jack, i read i could remove the cross member remove engine mount and use the jack to support the motor maybe the transmission , doesn't sound to safe considering i got to work on grass. I didn't know there was an oil named Delo that's a shortened word of my last name Dellow which is a brand of car. Pity i don't live up to my name im having car issues with oil lmao

@moff_man Yeah very strange went from running quiet too a noisey engine , and had people trying to tell me my engine is screwed and i said but it was running perfect yesterday it doesn't make sense it would die like that, I will check the oil filter out 2moro and see what the verdict is, I have another filter and more oil i will see how i go fingers crossed it is back to normal again .

Whats the worst case scenario i could be looking at ?
its a 1995 VS statesman has had a good run hitting just over 260000 on the clock
Most of its life has just been travelling on highways

[crackles23]

Hehe maybe silly comment but stranger things have happened, did you put your drain plug back?

[Delo]

@greenacc Hehe yeah it sounds weird to me too i don't have much experience under the hood but did sound a little bizzar, I did make sure to drain the right place i feel sorry for your friend that would of sucked.
I think i know the valve your talking about i seen it when trying to get to the oil pump it was on the other side of where the oil filter goes and little round piece of metal that goes between the timing cover and the other bit that holds the oil filter, thats a good idea though to protect the engine i was unaware of its purpose until you mentioned it .

Thanks again for your help guys

[9C1pack]

Did the filter come with a clear peel off plastic dust cover, did you remove it?
What about the oil does it appear thinner than usual? maybe the oil company filled it with a light weight oil by mistake (unlikely)
Try another filter on it, its only $10
I am not sure, but I seem to recall if you have an oil pump apart it is recommended to put grease/vaseline or similar in around the impellers so they can seal good enough to suck oil up initially.

[delcowizzid]

the valve you are talking about behind the oil filter housing did you take that off if you did the gasket is probably torn or the valve in wrong causeing no oil pressure

[Delo]

@crackles23 Wouldn't suprise me to miss a simple thing like that but i did check that one out but knowing me i could of missed something else lol , i bought a manual from supercheap 50 bucks well spent i think, being very amatuer with motors this gives me more confidence to tackle a problem myself

@9C1pack yeah the filter did come with the plastic cover you mentioned and was removed before putting it on , but the oil i used on the next oil change appeared thicker than normal it was the same rating as oil i normally used but a different brand , watching it go down the funnel seemed alot slower pouring it. I didnt actually get the oil pump apart one of the bolts started to slip and was starting to round off, i got the others off but no luck with that one, i used my fingers to turn it around and see if it pumped oil seemed to be under pressure pushing oil out as i tried feeding more in, I end up just putting it back on the motor without being able to check it out .

@delcowizzid Yeah i did remove the oil filter housing off when trying to remove the timing cover from the motor because my oil filter tool would not grip it enough to undo it, even when i had it off the motor it would not budge end up hammering screwdriver through it to get leverage to undo it and replaced the oil filter. I thought it would be easier that way but soon found the oil filter housing wont remove until you get to the bolt underneath the oil filter. The gasket seemed to be all intact but thats only my guess was no tears or breaks i end up putting some gasket goo and reinstalled the oil filter housing.

Thanks again guys for all you help im going to trying everything mentioned today and come back with hopefully good news

[moff_man]

the oil pump is located behind the crank pulley and runs of the crank shaft, if you could turn this when its on the motor than you oil pump is stuffed. the oil pump sits in the timing cover and is very large

[James39]

sounds like he was messing with things he should not of even touched and may of caused the problem.

[VS 666]

are you sure your driving a commodore? because I hear of these self blowing motors that a rival company makes... 4.0 straight six... it sounds like a jet engine winding up when it works and then the temp guage goes high but thats simply fixed with a piece of black tape... after a while this white stuff appears under the oil cap then the jet winding sound stops, funny enough when that jet noise stops the car does as well

[Delo]

@moffman Yeah i had the timing cover out and used two fingers to try turning it was hard to turn by hand but did see it pumping oil ,but removing the oil pump from the timing cover was a problem as one of the bolts started to round off so i couldn't inspect it.

@James39 You are probably right it went from running perfect to sounding horrible just from a oil and filter change, the first place i wanted to get too was remove the sump and clean out the pick up but not having the equipment or money to buy the stuff , all i could do was look for possibilities that i could get too. I think i should of come to this site first before attempting to fix myself.

@VS 666 hahah yeah that's all i ever driven is commodore's well except my first car Gemini <---( best 300 bucks i ever spent ) think i will steer clear of the straight 6 rivals i think dont need more problems .


I will be trying to start my car in about half hour new oil and filter ready to go.
The only thing that bothers be is that i did this once already with no luck and the only thing different i did this time was flush it with a diesel/oil mix, hopefully there was just a blockage somewhere in the lines and now gone. Either way i will be back with my outcome just hope its good news.

Thanks again guys for ur help

[badger__rox]

strange??? its not one of the rockers coming loose happened to me in my old vn i dont know how or y but it happened, also diesel isnt always the best thing to use as it tends to loosen up gunk and then in 500 km it drops and then blocks up the oil pick up, happend to me in my 5.0 litre, the engines are fairly cheap for vs commodores so rather the spend $300 dollars tring to fix it maybe just spend $400 on a second hand motor and pull the sump off before you put it in to inspect the engine,

[Delo]

The news is not good the noises and banging from the engine sounds horrible still, not happy but kind of expected this to happen. The noises are loud and cause the engine to run really rough and stalled twice. Time for plan B

@badger__rox I think your right about just getting another engine, all i need to do is find someone selling one and to put it in for me, i have no equipment to do that or experience, your right the vs motors are fairly cheap, i see i called one wreckers up they said $1200 for a changeover with 3 months warranty, i thought was a little steep knowing i can get motors for a price like you said $400 so $800 to install it i dont think so, way too much.

Just need to find someone close to my area with a motor now and hopefully pay someone to install it . Would it be worth trying to find someone on justcommodores.com.au, not sure if allowed to do that on here. buy and sell or offer services.

thanks again guys

[Delo]

@moff_man Cheers thanks for that moff_man will check it out now see what i cant find

[deanos70]

A lot of the wreckers warrenty's arent worth a pinch of salt
if you read the fine print some say unless its installed by a mechanic and you change this n that etc they wont cover you anyways

sounds like it could be a bearing shell if its knocking, i really dont think just doing the oil change could have stuffed things up
probably just a coincidence what evers wrong happened around that time

kinda sux but whate ever has happened to it

[Delo]

@deanos Yeah think i will avoid the wreckers at any cost, plus the warranty wont be any good to me im in geelong at the moment going home to brisbane soon well as soon as i have a car going hahahah.

The noise has a knocking aswell really seemed to struggle to idle, i gave bit of throttle not much to see if it would speed up the sounds , the knocking doesn't seem to keep a pattern all the time almost like knocking/noises at random times but still constantly making noises. Poor car sounds like its dying on me after being so faithful to me, this has been the only car i had that i felt could trust and no fear breaking down on me but not the case anymore will be paranoid if it goes again.

Most likely options will be try to find a new motor for it
or sell it for what i can to get myself a cheaper commodore and take the loss on the chin
I was looking at getting a VT commodore wagon and trade my statesman in but without a motor dont think thats going to happen now hahaha

[greenacc]

Mate are you sure this is an oil problem ? Does the oil light on the dash light up before you start it and then stay on or switch off when the engines running ?
Hows the harmonic balancer on the engine ? maybe thats let go and making all the noise.. or did you leave a a spanner on the engine when you changed the oil ? Just sounds like there's something sus going on here.

[Delo]

Yeah the oil light comes on before it starts then goes out once the engine is running.
I made sure to line the harmonic balancer up right and done up tight, made sure nothing was sitting on the motor before starting it up.
It sounds very suss to me too but since i didnt have the right equipment and never got the sump off its more than likely the pickup is blocked.
Before i flushed the engine there was no oil coming up when i removed one of the rocker covers, after flushing it and leaving the diesel/oil mix sitting in the sump
overnight then draining it and putting new oil in i noticed a few bubbles come through a few but thats it. Still very noisey so didnt leave the car running that
long just enough get pressure up in oil.

Still not sure what to do all i know is i got to get the car going asap, while saving for a engine changeover i will keep trying to fix this just incase it does go again jus dont want to spend anymore money on it could be just wasting it . So whichever comes first pretty much.

[badger__rox]

if it kinda comes and goes id say its the harmonic ballancer, if the oil light goes out then it shouldnt have a blockage, just see if you can wobble the harmonic ballancer and if it wobbles then it will be that if your prepared to change over the engine over id just take it for a drive worst case senario engine will seize we strapped nos into my mates vn v6 stock motor and tok it for a drive it had a knock before hand so we didnt really care but it still drove home blew alot of smoke but kept drving just if the knock gets really bad dont shut off the car cause thats where it it be stopping lol

[SEXPAC]

honestly put a liqui moly engine flush in it and then change the oil and filter again

buy the sounds of thing the oil is of shit quality

u need a 15w?40

was it penrite by any chance
