Vr V6 Running on 5 Cylinders

[Sara Pax]

My VR lost a Cylinder on the weekend
Well its still there but not firing
I put new plugs and leads in her today and still the same
I put the timing light on each lead and No. 2 is dead
So does this mean No2-5 Coil is stuffed
Or could it be a bad connection in the coil pack
All help appreciated

Gap the plug down to 1.0mm and see if it fires.

Hi Mate
Just wondering what your background is
Are you a mechanic
Let me know

[hako]

I'm not a mechanic, just a car owner who has always fixed his own car(s) over the last 50 years and also fix my kids cars as well. When I give advice it's to the best of my knowledge and given in good faith. I do have a technical background and prefer to have dirty rather than clean hands.
In the case of your cylinder not firing I suggested gapping the plug down to 1.0mm instead of the recommended 1.5mm. This may enable the plug to fire at a lower voltage if you have a weak coil or the plug lead to that cylinder having a high resistance. To my way of thinking that would be the first test I would do - plus it is simple and costs nothing.
Next test would be to measure the compression on that cylinder which is only possible if you have a compression gauge, however in the absence of a comp gauge you can roughly figure out whether the compression is down on one cylinder by first pulling the fuel pump fuse then running the engine till it stalls then crank the motor over - it should turn over smoothly if all 6 cylinders have similar compression ratios, but if one cylinder has lost compression the motor will stumble and not turn over smoothly. Do not run the starter motor for more than 5 seconds - wait a few minutes for it to cool down.

One big problem with giving advice or help on any forum including JC is that you never know the ability or inclination or whatever of the person giving or receiving that advice - which is why this is a long post to try and explain from my perspective! Good Luck.

I will not chime in here because obviously you are wary of harming your car, but doing what he said cannot harm anything so its worth a try.

Thats OK mate
So whats your Tech Background
I am not a Mechanic either
But have a dirty hands tech background too

please no offence, but is this a job interview?

what the fella said is correct, but will be a short term fix, if the coil is breaking down

Sure mate
Do you want to apply
Are you a Mechanic

yeah your cool do you want help from these guys or not........

i sure am but i wouldnt work with/for you,

[Sara Pax]

i sure am but i wouldnt work with/for you,

Why not
Maybe i know more than you
Considering your a Mower Mechanic

[waffles666]

stop being a tool, go pull the stupid plug out and give it a go or if you think you know better go to a junk yard and get a new coil. If my car was a screwed as yours sounds like i wouldn't be wasting time running my mouth, if you don't want help don't post.

pour some sugar in the fuel tank...guaranteed to bring the other 5 cyls inline with the crook one...

i am, but im also a light vehicle, heavy vehicle, heavy plant and earthmoving equiment,

in saying that though, if you knew more, you would have had it fixed without creating a thread on a website

i also wouldnt do jobs for you cause you seem like a nut case that expects more than whats realistic

My background has simply been chasing balloons - weather balloons. From the time I left school till I retired at least twice a shift I would release and track a weather balloon either with a theodolite, windfinding radar or GPS....sometimes with a radiosonde attached. We even made our own hydrogen for the balloons using ferrosilicon and caustic soda. My job description was Technical Officer and apart from playing with balloons you also had a raft of other instrumentation which you monitored and reported on 24 hours a day. You generally worked on your own, at one of many remote weather stations like Charleville, Mt Isa, Giles etc and if something breaks, you fixed or replaced it. We used slide rules initially and graduated to computers well before the general public became aware of them. I find it quite amazing that just on 50 years ago in 1959 when I joined the Bureau we were receiving satellite pictures for the TIROS weather satellite.....ain't nothing new!
Anyways, I always loved playing with anything mechanical and whilst half my time would be spent on administrative duties I would always grab the chance to pull something apart.
So to used that old saying, I know a little about a lot and a lot about little. Win some, lose some.
Apart from the paid work side of life I've done most things from rewiring a house to demolishing one and similar with cars, trucks,trailers and wheelbarrows. I tell my grandkids that I can fix anything except a broken heart....they understand that.
Really I think a lot of JC members have similar inclinations....good fun and as a bonus you get dirty fingernails. Good Luck.

All help appreciated

Shit no, I'll keep my tongue in my head.

Reminds me of a thread a long time ago, that someone is now using as a sig.

"You come on here and ask me for help, then tell me im wrong? here's a big @#$% off to you! "

[waffles666]

By the way you should listen to hako he's a good bloke, always giving helpful advice on almost all the threads i have read if only there were more people like him.

[Sara Pax]

Gee a lot of you have a great amount of "Shit on the Liver"
All i asked was if he was a Mechanic
Then all this bullshit started
WOW

What i am thinking now is that any of you lot that are mechanics would be better off collecting trolleys at K Mart
Thats where your Expertise is
You probably couldn't diagnose an empty fuel tank

And to Mr Hako sorry if i offended with the question
Sounds like you had an interesting job from what you have told

You certainly did not offend me - so no problems. My kids are often remarking to me that people of my era saw the best days but I dunno.
Anyway, this forum is for friendly car talk so is the VS still running on 5 pots?

Here's an idea, go to a mechanic if you want to talk to a mechanic. Dont be all up in peoples faces asking what their qualifications are when people try to help, Im surprised hako is even talking to you at all.

You come on a commodore forum for enthusiasts and expect to be talking to a mechanic each time? Sad fact is, someone pushing a trolley at K-mart would still know more about cars than you. Probably have a higher IQ too. Jog the fu*k on.

Anyone with some basic common sense would know that making a smaller gap in a spark plug is not going to damage anything. F*ck sake your making less voltage. The guys here are trying to help you. And they always seem to give me helpful ideas and advice when I ask for it.. Keywords being there "Idea's & advice". Take what's given.. Being a rude c*nt won't look so good when you ask for advice next time.

And yes, I agree with hako, smaller gap will decrease the voltage which will give you a "clearer" indication if it is the coil.

My background: Electrical Engineering, 2nd Year Uni student. Is that good enough for you?

[Sara Pax]

**** me dead you wankers cant stop

The car is fixed

Faulty coil

And while i was there i whacked in some new plugs and leads as they havent been replaced for yonks
the car was fixed while all you nasty tossers where typing ya crap
Pull the corncob out ya arses

[hako]

Good to see it was just the coil and not a bad valve or worse. Just for info, if the coil was the problem on number 2, was it OK on number 5? Reason I ask is I'm a bit curious as to whether the coil actually has 2 sets of individual primary and secondary coils inside the one coil.

you come in a forum, and ask for advice on why ur car isnt running its best, you get ur answers, then you critisise if the person giving advice is from mechanical background ?

You Fool
