weird noises pls help *look*

[fuzzy2308]

a mate borrowed my Ute to go to the tip yesterday this morning i started her up and she made a screeching noise coming from the front of the engine iso i turned her off and had a look and couldn't see anything o i tried to start her again and nothing hap pend about 7 tries and she started then she started making the noise in the vid attached (hard to explain the noise) the more revs it does the more often and louder it makes the noise......
i rang the mate and he said he was turning in to the highway and gave rev-ed it out to 4&half and it the engine stop but it didn't stall and it made a loud clicking sound then it went away.....



please help

My guess is one of the pulley bearings has failed - remove the belt and turn each pulley by hand to find which one is stiff/rough.

[5ivespeed]

cant hear anything screeching. but if it sounds like a really high pitched squeal it could be air squeezing out of a faulty gasket

[fuzzy2308]

cheers. do u think itll do damage if i keep driving it?

[hako]

If it is a pulley bearing and it fails it will eventually throw the belt and you will have no power steering and no water pump......however it may last for a few days (if that's the problem). It only takes a few minutes to check if it is a pulley and it is very cheap insurance compared to a seized engine which is the worst case scenario.

[fuzzy2308]

i just went out with a torch how do i get the belt off

[hako]

Locate the tensioner pulley - thats the one that applies tension to the belt - put a ring or socket spanner on the bolt head of the tensioner pulley and rotate ANTICLOCKWISE to take tension off the belt...remove belt but first note how it fits on the pulleys....draw a diagram. The tensioner pulley bolt has a left hand thread so you must turn it anticlockwise to rotate the tensioner.....do it slowly and gently.

[fuzzy2308]

will do it after work 2morrow if i get time i will post uo how i go.

if any one else has an idea of whay i could be let me know pls

[fuzzy2308]

but yeah eny other sugestions of whay it mite be?


thanx

[TUF UTE]

what the **** .... on my computer it sounds like a knock or piston ... get a long screwdriver and with the handle to your ear touch the other end against various places on the motor and it shall act like a automotive stethoscope and find the source of the noise

[cander24]

Could be just the speakers on my computer but that sound combined with your description kinda sounds like your mate has spun a main bearing, though hopefully im way off otherwise I would have said its one of the bearings in a pulley.

[fuzzy2308]

i had a good chat to old mate last night after a few beers he said he rev-ed her to 6-grand could that of done any damage? and be the course?

also thanx Dave the noise is comming from the drivers side valve cover At the front just behind the alternator,



is their any thing i should knoiw before i take the valve cover of?

[Cursed CX8]

well at least your mate is honest with you. This is what i would do

1) pull out the spark plugs on the noisy side one by one. Look at them, look for damage and wear. If there is damage we know that there is either metal floating around your engine and that, that is the damaged chamber. If it is worn them replace the spark plug, you might just have a terrible miss

2) Take the rocker cover off, take care not to snap the screws holding them in. While you can see the rockers rotate the engine by hand and see what valves are in which position when the sounds is made, then refer this to what we know from looking at the spark plugs to determine if its inlet or outlet valve.
If its one of the valves, you can either take your car to a mechanic, or rip the head off and take it there. Id suggest not driving it as you will be doing damage to the bottom end.

3) If its not the valves and all are working, but the spark plugs are stuffed then change them and see what happens.

4) Check the coolant for oil and oil for coolant. There will be a creamy residue in the oil if it has water in it.

REPORT BACK.. Ill have a think and let me know

For your sake I'm hoping it turns out simple. Re the pulleys, you say one is stiffer than the others and you'd post a pix - when they get rough the sound can travel via the serpentine belt and appear to come from somewhere else and be pretty noisy.

[fuzzy2308]

well i have tears now shes ****ed just took her down to mechanic and she neeeds a new heart,


thanx 4 the advice and all the help guys i appreciate it alot.

[immortality]

damn that sounds ****ed. revving it to 6grand should be ok on a ecotec. definitly not a pulley problem. sounds like it's lost a cylinder or 2. hope your mate is nice enough to hand over some folding stuff. what did the mechanic say?

[VSIIBerlinaL67]

it should of taken a 6k my old ecotec with 300,000ks sat on the limter for a while and was fine. now that engine has been in 4 different cars lol and still going strong.

where does the sound come from can you tell? which pulley was harder to turn than the rest???

the sound was comming from the drivers side rocker cover the noise turned into banging just before she died the car no power and was strugling to get to 40 ks on the way to the mechanic.

it wont start now it made a huge noise like when your let all the air out of a balloon reaaly quick,

the mechanic said the cam was snapped and the pistons were ****ed also the main bearing was gone,

im in to minds what to do with her i really dont know should i keep her and give her a heart transplant or sell her or sell her in bits what do u lads reckon.

[VSIIBerlinaL67]

*** is your mate gonna pay for ya new engine lol? see if you can find a l67 and drop that it

[vr_calais]

thats crap let your mate borrow the car and he treats ypur property like that some mate hope he helps with fixing it i know somebody if he was my mate i wouldnt be letting him borrow my car ever again borrow his car and thrash it see what he says when you give it back to him with a blown engine

[fuzzy2308]

this is her My FIRST CAR, VS UTE how much do u reckon she is worth witha blown engine?

i dought that mate will be coughing up any $$ i think he will be x-mate

[howepower]

typical example of a car that is not serviced on time every time

it would not be bigends it would ba gudgeon pin fault and the cam broke because it was blocked with carbon look after your engine people service every five thousand if you want to look after her

[JT090]

hmmmmm go to a wreckers pick up a cheap ecotec for $500 (ish) chuck it in and get rid of it, imo its the best thing to do mate, willl get more $$$ for it then, especially if your handy with the tools and can do most of the work yourself or know someone

or buy my ute and transfer everything over :P;P

[vr_calais]

expensive lesson i must say and your so called mate causes it and its your first car that has to be heart wrenching to know what other people do to property thats not theres to abuse nice mate you do him a favour and look at the respect people have at a guess would recon it couldnt be worth to much with a blown engine if the car is in good condition i would proberbly look for another donk to put in it and tell your mate to go to hell if he doesnt cough of up with money and never let him borrow it again

[XeKToReX]

swap cars with him, id be makin a mate cough up cash money if he thrashed my car..
