well I was driving about 45 and gave the car alittle gas. didn't floor it at all. just enough to make it up a hill. The car studdered very bad and then started blowing white smoke. it will barely run and won't hold an idle at all without giving it some gas. also when I pull the oil dipstick white smoke comes out.

I blew a piston ring once on this engine and had toyota rebuild it. but the car drives much worse than that time and WAY more smoke. I had a trail the whole way down the road of smoke.

think i trashed it? I also notice some oil in the engine bay. I couldn't see a hole anywhere and the oil level is only about 1/4 of a quart low. suggestions?

ps. I'm on my phone so sorry for crappy grammar

 

well just did a compression test. 160 155 20 160...ouch I think its new engine time.

 

headgasket or piston rings imo.. time to get built.. you have a low oil pressure too?

 

dang i know how that feels... happened to me 3 time... not a typo yes 3 times..

 

Damn damn damn!

Sucks to hear.

Let us know exactly what caused it yo.

 

Damn ZPI

 

i dont think blown motor has anything to do with the turbo kit.. its more on the tune or maybe just increased wear.. eventually stock motor will go after sometime of abuse and increased wear by FI

 

Damn maybe i should stop abusing my girlfriends tC, I see blown motor threads floating around here quite often..
Sorry to hear, Time to build it!

 

That all depends, get an eBay kit and talk to me in 2 months

It really just depends on how much boost is being run and the overall condition of the motor before the install. There could be some underlying problems that might not have been seen prior and the addition of FI just increased the degradation of the motor. I do believe it has more to do with the tune and if you want your stock motor to last hundreds of thousands of miles you don't run huge amounts of boost.

Hopefully the OP can find another motor for not too much.

 

was referring to his kit in response to a post above, i dont think him having a zpi kit blew the motor.. the guy was boosted way before me a long time ago.. so with his case i think its the increased wear factor.

and oh about ebay kit.. there was a guy in the race track running one on his built civic he just changed the turbo, wastegate and bov and never had problems over a year of boosting.. he's running some good boost and run low 11s in 1/4mile

 

Once again, the increased wear factor is a minimal one at best. Properly turbo'd and tuned tC's have been known to run hundreds of thousands of miles with no problems besides the maintenance of the turbo. Like I said if there was an underlying problem FI would exacerbate that problem which could lead to a problem over time. I just don't buy the increased motor wear causes a motor to pop at a relatively reasonable amount of miles. It also depends on driving style and if they beat on it. The tC motor is a really reliable motor under most circumstances.

And in regards to that eBay kit, the guy swapped out all the major components of it. New turbo, new wastegate and new BOV; the only thing he kept was the manifold IC and piping it seems like, as long as that isn't leaking that isn't going to cause a problem. That's like me buying a Dezod kit and changing the turbo, BOV and wastegate.....can it really still be considered a Dezod kit; no.

 

i would disagree with you on this one.. how many guys turbocharged on stock motor do you know lasting hundreds of thousands of miles, if their is one they prolly dont it boost at all.. thats the normal toyota engine life on a non raced stock engine.. i can even see stock tc with blown motors.. wear is not minimal on our na designed motor.. a guy that turbocharged his car most likely race right? and we or not sure how often he does.. although like you mentioned if something is wrong with the system or the tune it would fail prematurely and but its gonna fail in less than a year or two

 

I'm boosted but I don't race. I've never gone to the track or anything like that. I don't launch my car or anything else. Its my DD that just so happens to bu turbocharged but its because I wanted to do it, not so that it can keep up with whatever else is out there pushing 300whp.

I guess that puts me in the minority.

I put a lot of miles on my car from driving back and forth from Auburn to Charlotte but that's just highway mileage, typical stuff, not blazing down some race strip trying to beat a 5.0 mustang.

 

its a bad thing to beat a 5.0 mustang?...lmao... j/k

 

but still you race your car on the street? or race the engine aka hard driving.. the guy had a bad piston before so that might be something to think about maybe its actually the tune.. but i think this guy races and drive hard and does tuning too

 

If that's your thing by all means go for it

I have mine for personal pleasure not for spirited racing.

 

me? I don't street race. I did it once but that's when someone asked me to take it from a roll at 20. That was before I had the turbo installed. I don't drive hard either, I speed but drive hard as in red lining, power shifting and all that nope. I just read what brake boosting was yesterday. I didn't even know what power shifting was until my buddy told me about 3 weeks ago.

Sorry, its my first turbo'd car and first stick shift.

I'm still trying to figure out how not to stall with the stage 4 clutch.


EDIT: I see that you were talking about the OP. I saw that he did have to get a piston replaced, the dealer did it for him.

 

Could be another piston ring maybe. Oil in the engine bay is definitely a no-no; there has to be a leak somewhere but maybe that's just the end result of the problem.
