Cheers,

The NRMA guy plugged his scanner in - nothing came up except O2 sensor as a result of the raw fuel pushing past it. I have one of these for my Bimmer (BMW specific) and its a godsend.

Thanks! I might give these guys a call, they'll probably know what my problem is.

What evidence is there to say all 4 cylinders aren't firing? Sure it's not just one (or two)? Head gasket?
Mechanical problems generally don't come & go. IE: If the timing chain on that bank has slipped, it won't periodically 'come good'.
The only 'mechanical' issue I can think of that might fit that description would be a partly blocked oil gallery to the lifters on one bank, causing the lifters to bleed down. That would also make a lot of noise. But, I've not heard of that happening before.
Everything (other than the noises) would have me looking at similar culprits as those already mentioned. Fuel, spark, etc.
I read your post yesterday and have been thinking upon it. It sounds odd.
PS: If it is making loud internal noises then running it will potentially do more damage, sorry.

I'll be keeping my eye on this, good luck!

A couple of things come to mind here:

Yes the Toyota idea was a stupid thing to say, don't even joke about it. You would be better served by selling it off and buying a Patrol.

If something mechanical has failed then most of the mentioned tests, whether by you or a mechanic, will do further damage as they involve rotating the reciprocating components. A camera scope would be a wiser investigation.

Getting a generic mechanic to look at it, whether at his shop or your house, could be no better than the NRMA guy as they are normally mechanics anyway. Make sure they know Jeeps or go to a Jeep workshop or you could be wasting time and money.

Without actually hearing it in person, could it still be fuel related. Many engines if firing badly or only on a couple of cylinders can sound pretty crap. Especially if firing in an unbalanced pattern. Are you sure it's all 4 on the one bank.

Plenty of things to check after doing a visual inspection down the bores.

Swapping coil packs around. Good diagnostic tool that can fire the injectors without running the engine. etc etc.

I wonder if it could have stripped a keyway on the cam. Still none of this mechanical stuff ties in with it coming good and then going to $h!t again.

If not, just get rid of it as you said and get the toyota and good luck there. As if they don't fall apart.

thanks guys. Its going to an independent jeep specialist for a proper diagnostic. I'm not going to run it at all given the noise its making, if its timing chain slipped then that could be valves and rods smacking about out of wack from what I've read about the traps.

If its going to cost more than $2,000 or so to fix then its probably not economic for me - I mean what else will go wrong next, trans, head gasket..

Although after fixing the blend doors I do have heat in winter and cold aircon in summer - though I did have to cut into the A/C drain to remove old sponge that had turned to sludge and blocked the drain hole - a whole new story there...

I really hope its a fuel or spark issue, really, really do, but suspect the worst.

It goes in for its medical in a couple of days. I'll let you know what the result is. Who'd a thunk, 123,000km with full service history and in show room condition, it would break.

My R31 Skyline with the RB30 lasted 380,000km with only one timing belt change (at 120,000), still purred when I sold it.
