Yeah I think so. Or a holed/broken piston.

 

what brand of fuel were you running?

 

I have heard of somebody who lost a piston because their fuel filter was clogged, might be worth checking that when the car is being fixed.

 

Terry also said he can get full engines at a reasonable price so worst case that might be the way to go.

 

Feel gutted for you, this would be my worse nightmare. I wouldnt be able to afford to get it fixed and the car would just sit there while I save up for a new engine.

As soon as I withdrew plug #2 from the hole some of the same white smoke drifted out. The smoke smells of antifreeze so I guess the headgasket has gone as well. BHG wouldn't cause 0 psi on the compression test though, would it?

Ouch :cry: Look like 2 Cyls down there and the plugs confirm it ....well its now down to the lesser of 2 evils..Head off ..and see if you have taken out valves ( wish and hope ) or worst worst case is fried pistons and scored bores.....so sorry to hear this you need it like a whole in the head .

Don't panic yet, it's still all inconclusive. Get the head off ... you know Tel will sort you out with a new shortblock if you need it. Arnout does exchange heads for VVTi's with special bits ;)

 

If the engine let go you can guarentee the turbo's are dead too. :( But this is what this community is for...we'll find you the bits and save you a packet over Mr. T. But I'll say this now, don't scrimp, pay once fully and dont cut corners or you'll pay twice.

It was an Elf petrol station, JB. I was desperately low on fuel and was going to do a 'splash and dash' to get me to a Shell/Esso garage but I saw they did SUL97 and thought it would be OK just this once.

 

It wasn't even cheap! It cost over £60 to fill her up.

ELF & TOTAL are the same, I've used TOTAL on mine and she's still here.

 

Indeed, Lord Mycroft used to say that Elf/Total was the best fuel around. The only problem with Elf stations is they arent normally busy enough to turn over enough fuel so it could be it had degraded a little. I still think theres something else to it though, either a bad fuel pump or blocked fuel filter which caused it to run lean, and combined with the heat it just killed it. Im sure I lost my UK spec turbos last year because it was a seriously hot day and the cooling just wasnt there.

Indeed Mycroft did used to bang on about that ;)

 

The cause could be so many things....getting the injectors flow tested would be good, same with the pump and the filter. The FPR, could have locked up in the heat. Could have just been a build up on the plugs inhibiting the spark...Jake, does it have an atmospheric BOV? An atmos BOV could have caused the issue cause this car has a MAF, everytime the BOV lets go the fueling would have been mad rich. Have to say it never killed my VVTi before my upgrade, but I really noticed it once I put the 650's in.

 

Anyway, Jake needs to do lots more investigation work before we go bonkers on ideas why it happened.

Would a low mileage (less than 36,000) 1998 car have a tired fuel pump or clogged fuel filter? Seems unlikely but anythings possible I suppose.

 

That's why I thought of injectors...cause they've not been used much IYSWIM.

First thing I did when I bought the car was change the fuel filter, right after the oil change. You never know.

 

As for fuelling in general, without a wideband you're in the dark really.

 

So much for my theory of the VVTi 'overprotective' ECU, eh?

God no. I can't stand the things.

'Head off' is the next step, right?

I haven't had a car cylinder head off for like 15 years. I've done a few though. Anyone know of a "How to take your Supra head off" guide?

 

I'm not looking forward to this job but hopefully with you guys support I'll struggle though.

 

Thanks fellas, you're all stars

:respekt:
