HELP

I need an expert to help me

Car is running on 3 cylinders and a replacement coil pack has not helped.

246 bank is misfiring 0300 0302 0304 0306

Occasionally it will rev high with a lot of throttle then it will struggle to idle.

It was running fine until 08:30 yesterday when it decided to get very noisy, then shut off then restarted on 3

I haven't even got the power to reverse out of my parking space.

I am completely out of ideas and I just don't know what to do.

Cam timing is fine.

[KillerWatt]

0300 = Multiple misfires detected
0302 = Cylinder 2 misfire
0304 = Cylinder 4 misfire
0306 = Cylinder 6 misfire

I've read a couple of other posts you've made about this issue and what you've done so far....next thing on the list has to be a compression test (especially as you said it got noisy before the fault appeared).

I'll see if I can find it, any idea what pressure they should be?

[KillerWatt]

any idea what pressure they should be?

Off the top of my head, absolutely no idea at all Martin.

You definately want to see in excess of 100psi though, and I'd guess the true figure you want to see is probably around 130psi.

Do a test on cylinder number 1 as you know that works, and use that reading as a reference point.

[Martin_1962]

Will try tomorrow if not raining

Will look for pressure tester quite soon though

[Martin_1962]

1 150
2 very little max 80
3 140
4 eff all
5 150
6 can't get to plug

That tells you all you need to know then Martin.
Whatever has happened, you have lost compression on the 2,4,6 bank for some reason.

Next step is head off to have a looksee.

What a b*gg*r

Looks like I need to lift 246 again

I am so peed off I could set fire to it.

Even thinking now of breaking it.

You say cam timing is fine?

You fitted the cam sprockets correctly?

was this the bank where the gasket was put on  the wrong way round? If so have you replaced the gasket?

Yes they were still tight

Bad gasket is on 135

If theres no compression on that bank then I would have thought a load of bent valves.Timing slipped?,broken camshaft? :-/

[candyman]

check vour timing the old fashioned way before u lift your haed off. find tdc on each bank and watch the lifters as they rock. i had a daf engine once that craushed a woodruff key enough to put the timing out by 10deg.
