OK I got the T3/T4 on last night and went around the city block but blew my lower IC pipe I made off no probs I was making 14 PSI @ WOT when it blew with .96v 02 so I limped it back to work only about 1/2 block and fixed it out around the block I went 9:30 PM blew the IC pipe again so I called it quits.

Went back today and fabbed up a new lower IC pipe and went for a drive odd my car has so much lag its insane and won't build more then 7 PSI of boost at the shift it spikes to 10 then falls back to 7 psi and drops as RPM rises.

I drove it home and when I got out and left it running to cool the turbo I noticed its smoking quite heavily blue smoke meaning oil burning.

Now what causes this on our cars? Burnt valve? Piston??? Im totally shocked at the problem and don't know what to do. I am going to make a pressure tester tomorrow to check for boost leaks but Im pretty sure thats not the cause. Car never smoked before the install and now won't make boost today does anyone have any ideas? Car starts idles and rev's normally just very slow spoolup little boost and blue smoke.

Plz Help! :cry:
 
Well I pulled the plugs out this morning nothing there pure perfect tan color plugs also this morning all the way to work and when I got to work no smoke but still hesitant to boost. It will hit 10PSI in first spike to 12PSI second then fall to about 7 PSI Im going to buy some stuff to make a leak tester and check for intercooler piping leaks first It may not be as bad as I think. The blue smoke might have been a touch of oil I got into the DP pulling the trubo on and off maybe! Hopefully anyways!

Any other idea's as my car being very hesitant to boost? I know the t3/t4 is laggy but I can't make pressure first test ride out I made 15 psi easy now I can't.

Im leaning now towards bad IC pipe leak but I can't tell where cuz I made damn sure everything I reused is silicone hose and welded so it really can't leak.
 
If it worked ok at first then you blew a pipe then you have a leak somewhere. The turbo won't work then decide not to work unless you broke the wheel (which I highly doubt) Check over all your connections with a boost leak checker to about 25psi (make sure you regulate your pressure down on your air compressor before you do it, 100psi would be bad) and use water and soap on your connections to see how they are.

If you have a leak you cant get rid of try some hair spray on the connection. Pull it appart and spray the first two inches of the silicone inside then slip it over the pipe and double clamp it. The hair spray will form a really tight bond that will not leak.

Whatever smoke you saw was just from shit running off and down the exhaust. Your not going to pop a piston with 550cc and your AFC already tuned at 15psi, not gonna happen. Just go over everything and double check it all. Don't assume something is ok because it looks ok, take it appart and inspect everything so you KNOW it's good.

When I get back I expect a ride in a pretty fast car... :thumb:
 
Thanks Jim Im talking to John right now the smoke is gone pulled the plug and they are perfectly tanned so Im looking into the boost leak now much more intensely! I can tell you this it sure was a fast car @ 15 PSI till the IC pipe blew~!

Jim In going to pick up my burned 5 speed today got it for 1800 bucks. Needs motor and soon trans when I get to it! Every panel is perfect though and Im keeping the leather seats should make a nice parts car.
 
OK borrowed a leak tester fixed a nice sized leak at the s pipe to throttle body assembled everythign and went for a dive same damn SH*T I have pretty much given up at this point and I am ready to park my car. Any suggestions? Is it possible there is something wrong with the turbo? It spins freely when I freewheel it with my hand so??? Im at my wits end. Car DOES NOT smoke.

OK So what is it doing now then? The turbo can't be busted there is not way. If it spins and doesn't smoke then it works.

(BC is kick ass BTW...)
 
What about the BOV? Any chance when the pipe blew the sudden loss of pressure might have messed it up making it leak like mad?

When I had the tester on there it didn't leak out the bov vent tube @ 20 psi so I didn't question it but maybe there is something wrong with it?

It's starting to sound more and more like that turbo is going up. If the blue smoke isn't being caused by the engine, then its most likely being caused by a possible bad turbo.

I highly doubt the turbo is having a problem besides he said it is not smoking anymore.

Jamie check the wastegate and make sure that it's not out of alignment. The backing nut was loose when you got the turbo and It could have loosned off and is keeping the wastegate open. Your not getting anymore than 10psi of boost which means the turbo is working it just isn't working the way you wnat.

There is a little retainer clip that holds the actuator arm on the flapper, pull that off and make sure the arm is back enough to hold good pressure on the wastegate door. If it's partially open then it will keep the turbo from being able to spool up fast enough to make anymore than 10psi of boost. This is also why you could not build anymore than 10psi with the vac line off because chances are it's partially open and vac line or no vac line it's not gonna make a difference. A boost controller will not help your problem either.
 
Thanks Jim John has it now. What about a leaking BOV?

Also I am gonna call him to checkup on the waste last night on the highway if I was cruising at 120 and stand on it making her rev it would hold about 13 PSI till it hit 4th then fall back to about 9.
 
Well all is well it was the WG what happened is when I slid my stock fan in it was putting pressure on the accuator and was holding the gate open a hair can't build boost like that. All is well and now it sure is a fast car.
