My Car Just Went Bang

[lilcrash]

Cruising down the highway I dropped to 3rd to overtake and something went bang, complete loss of power and black smoke pouring out the exhaust. I had to drive another 5 mins to get home and i had to quickly swap cars to go to the dr so I haven't looked yet, my main question is do you normally hear your turbo explode?

[Tangles]

loss of piston ringland?

thats what my rb25 did the other week. No bang though, and the smoke was grey/white not black.

[chef_stagea]

was there noise after the innital bang? like ratteling in the engine? and constant smoke or just on boost?

[RubyRS4]

With the little info you've just given, sounds like you've spat the turbine wheel out the exhaust. Sounds like you're up for a new turbo now bud.

Or he has just blown an intercooler pipe off.

[lilcrash]

It is still running ok. Feels like when I blew an Intercooler pipe in my celica, that's what makes me think turbo. I don't think there was any other noises but my car has lots of random noises so I just might not have noticed. Smoke when boost should be. My wife said it looks like fuel smoke.

[chef_stagea]

check ur pipes i spose :S... wdnt suprise me tho under load it just spat it of or blew out a hole in a silicon hose

[lilcrash]

All still connected. Hole in Intercooler I hope. Going down to start it and listen. Wish me luck

[RubyRS4]

If you've got no boost (power) and all it does is smoke, then I truly believe you've blown the turbo.

If it was a blown cooler pipe, your car wouldn't run ... barely idle.

I say pull the dump pipe off and look for a missing turbine wheel.

[lilcrash]

No noises, it free revs as a 6 should. Kinda sounds like my bros torana. I can't remember if I could normally hear the turbo spin. Il have to drop the exhaust off and have a look I guess.

[RubyRS4]

Free revving because there is no load on the engine to make boost. Yeah, remove the dump.

[lilcrash]

Anyone got any ideas for removing the bolts in the dump pipe. I snapped one when I put the jjr dump on and now I've got one stuck again

If it's stuck, drown it in WD40 or similar, leave it to soak; then loosen a little until it binds. Drown again, wind the bolt back in until it binds; this will work the WD down the thread. Just work the bolt back and forth; you may get it out.

If you find it seizes solid; it may be better to just break the bolt off, (ie turn it until the head breaks off) remove turbo and drill out, re-tap and re- stud.

It's a pain in the arse I know, but then you know it's right.

yer its not going anywhere now, so yay more busted knuckles when i snap it.

[lilcrash]

ok not sure if i want to fix it so watch this space, i might just part it out.

[chef_stagea]

so it is blown or not? just drop the cat off.. it would have held it there if it blew it back... there will be reminence if the rear wheel went!

[lilcrash]

I am still trying to get the dump off, i dont have a cat, if it came off it would have went out the tips. There is nothing to stop it.

Try removing the turbo with dump pipe attached, by undoing the 4 nuts holding it to the exhaust manifold. Undo all your lines etc. Its a pita but you'll have it off quicker than f**king about with tight bolts on the dump. Once off you can then separate the dump and replace the seized bolts. Chances are, you'll need the turbo off anyway to rebuild.

I do this to my turbo when I want the dump off, because its a bellmouth pipe with bugger all room to remove whilst the turbo is on the car

[lilcrash]

Yer I have a bellmouth dump too. Is it hard to maneuver it out of the engine bay being over 3ft long?

[chef_stagea]

na its easy as...
