I've blown my car up

To be fair if it is the turbos there are so many of them lying around spare now that shouldn't really cost you a huge amount to sort. A head gasket on the other hand would cost you a significant wedge. Like has been said though don't jump directly to any conclusions. i had smoke screens coming out the back of mine a while back and it turned out to be nothing more than an overfilled transmission. I'm not sure how many things can cause the oil cap to blow oil every where sometimes funny things can happen inside an engine. Backfires and misfires are weird affairs with airflows all fecked up, ignitions happening when they shouldn't in places they shouldn't.

 

First things first before you do anything else pop the plugs out and have a look at them. If theres bits missing off any of them then you can begin to get worried. If they are intact and look OK for correct fuelling then get yourself a compression tester from halfrauds (they aren't mega expensive I think they are about £40). Do a compression test and see where you stand. If all is well there then the turbo's need testing, how you do that on the car I don't really know. If all is not well then if you can get access to a boroscope or a cylinder inspection tool (most garages will have the latter) pop that down the affected spark plug hole and see if you can see any damage inside (should be able to see if there is a gaping hole in a piston or a bent valve etc).

 

Remember though before you go spending hods of cash on a serious rebuild that you can pick up TT engines with all the stuff bolted on them for around £1600 and may be a better option than rebuilding to have some inherent fault cause the same again.

Jake - I'm so sorry to hear about your trouble. Like some others I just wanted to offer sympathy and wish you luck in getting it sorted out :grouphug:

 

Yep - waiting for a report on what has gone wrong :cry:

 

CJ - :no: Didn't you just get your tangomobile back on the road? I hope you get things sorted out quickly too. :hug:

 

It's at times like these I'm really glad I don't have any turbos ;)

Yes, only been up and running about 3 weeks :cry:

I am begining to feel the same way!

I wonder if this turbo-failure streak is related to the high ambient temperatures lately, coupled with poor quality fuel and the 'performance' cone filters many people run (resulting in the turbos inhaling even hotter air)
Standard air box on mine John. Converting it back to stock was the first 'mod' I planned when I bought the car back in Dec.

 

The thing about high ambient temps had crossed my mind too.

 

The guy I work with drives a Saab Turbo. His turbo died on Sunday and already has been replaced with a brand new genuine OE one. £900 inc fitting

MMM mine had a nasty couple of backfires the other day when running in parrallel mode with cheapo sainsburies fuel in it (an AMG merc convertible of some sort needed showing some heels). Fortunatey thats as far as it went.

If ambient temp is 30C (I've seen up to 34C here in Kent lately) then underbonnet temps can easily exceed 50C with the car moving (way over that when idling in traffic)

That is a lot, considering that the i/c has 34C air to work with. Plus a lot of the heat the i/c core sheds goes back to the engine bay for those with FMICs (not very smart)

The rule of thumb is that for every degree the intake temp goes up(or down), so does the EGT. If your EGTs are already marginal (stock turbos running high boost), this could push them over the edge.

 

Not to mention fuel fizzling out much quicker in these temps (lighter components booger off)

MMM my EGT gauge started bleeping at me as well and hit nearly 1000 when I backfired. It dropped straight back down to 400 when I lifted off and coasted. Perhaps its time to fix the water injection kit.

Mine bit the dust over a week ago before the heat wave struck.

In a way I'm lucky that my (ICV) nipple snapped today, so it's effectively crippled to a ceiling of 4Krpm.

 

When I took it yesterday out for some 'tests' to adjust the EGBV bleed levels it kept making burbling noises for a long time after I switched it off. I expected the cooling system to behave better with the fresh coolant it's got, especially it being weak (75% distilled water).

Even though I have replacement turbos in the garage, I'd be pissed off if one went pop.

Having owned my Supe for over a year now, I've toyed with the idea of BPU'ing the car, but when I read threads like this it makes me think to stay as I am.

 

When I was in France last weekend it was quite significantly hotter there than here, and on the way back on Sunday was driving hard for over an hour after long stretches stuck in traffic. And it didn't miss a beat.

 

I don't have gauges that give EGT readouts but I know it was bloody hot as I set the grass on fire when I parked up at our campsite!!!.

 

Makes me wonder...... extra 80bhp for 1ksih or reliability? Dunno.

 

Jake I'm gutted for you hope everything goes ok.

 

CJ I'm even more gutted as I was sooooo looking forward to a blast in your car. Hope its nothing seriously major.

After the cops had breath tested me (passed for alcohol, failed for halitosis)

 

lol .. :D

I have the temp. probe of my boost gauge sat in the corner of the engine bay sort of in front of the driver, right up to the side, and in this kind of weather it's not uncommon for it to register 65c :eek:

Ian C said he got 70degC in France at the weekend...his Single didn't miss a beat ;)

We get 30+ degrees for around 6 months of the year here and regularly in the high 30's in the summer, touch wood mine has been running fine for a long time now at 1.25bar. Mine was dyno'd/mapped in hotter temps though so that may have something to do with things.

Nothing whatever to do with this piffling little warm spell, hell, all modern cars are tested to withstand towing a caravan through Death Valley with a full compliment of hefty passengers, too. It's not even been that hot, relatively speaking. For some reasonn it's detted, I would also very much doubt it's fuel related. What are the plugs in it? Copper ones :( ?
