car won't run....can anybody help

[crazysupra2JZ]

my car was running fine the other day. i got on the highway and decided to go fast on the on ramp. it hit 4th and the car started losing power and smoking REALLY bad. oil was burning somehere. i barely got it back home. it was puttering and barely stayed alive. so i thought maybe it was the head gasket. so as i was starting to replace it i noticed after i took the exhaust manifold off number 4 cyl exhaust port had oil in it, the others were dry. so i was like. uh huh...there's my problem! but i eventually got the head off and the head gasket looked fine. a couple of things on it were questionable, but number 4 cyl looked just like the others, no major damage. so i put a new gasket on and set the timing and filled up with water and checked oil. everything looked ready to go. so i started her up. it won't even start now. somwtimes it will catch and start idleing but i have to give it gas. but i have to press the pedal really fast cause too much will kill it. smoke is coming out of the engine again. but i know where it's coming from.

so i'm thinking the front main oil seal is gone, so i'm on my way to get a new one and all other gaskets i need to do it properly and i realize........maybe......the piston rings are fried on cyl 4. i'm losing compression, oil is getting into that cyl and burning, then coming out from where the main oil seal is. smoke is coming from that area.

soooo......now me and the mad scientist are gonna have to rip apart the block, and replace the piston rings i fried! cause i doubt the front main seal going bad would make my engine run, or excuse me, not run like that....anybody.

sounds like when i blew my turbo. have you checked that?

 

[Supraboostin]

so you did a compression test?

 

[crazysupra2JZ]

the turbo was fine. no shaft play at all. spins nice and free.

no i didn't do a compression test. as soon as i saw the oil in the exhaust port i figured it was the head gasket, plus the coolant was milky and for sure had oil in it. and i had the waterfall sound, which i noticed about 2 weeks ago.

let me be the first...

what supra owners fear most

 

[mk3_dude]

if you got a harcore oil leak, its your front main seal.

I say you are another 100,000+ 7M victem of the famous, BHG. rebuild time**

 

[crazysupra2JZ]

well, i changed the head gasket. it runs the same it did when it happened. can bad piston rings cause the engine not to run? if it's the main seal i'll fix it now, but if it's the piston rings then it will have to wait tilll march.

 

[mk3_dude]

CHECK your Intercooler PIPES before you do anything. If thats not your problem, Compression Test. If compression comes weak, i'll have to say your RINGS are going bad. Does it puff out white smoke out the exhaust at start up?

--i can guarantee you 99% that its not your front main seal. Front maint seals only cause major oil leaks that you cant control unless you change it, it has nothing to do with the way your engine runs.

 

[crazysupra2JZ]

ok, tell me what you think about this. valve stem oil seals. can i be losing compression through that. could air be forced into where the valve cover is and blow oil through the pvc system. i noticed oil around the air filter to my catch tank. then the air could also be forced into the crank case through that hose and anywhere there's a bad seal it could be forcing smoke through it. i am leaking oil in the front of the engine. i think the oil pan isn't sealed up good.

 

[crazysupra2JZ]

anybody think that might be it

 

[crazysupra2JZ]

well. i got it running. i used the safc to make it idle better. but it's nowhere near driveable. smoke is coming from the exhaust manifold. and i hear noises from the crank pulley area when i rev it. smoke comes out too, but only when i rev it. also tons of smoke is coming from exhaust, white smoke.

Blue is oil and white is coolant

Does the idle spudder or jump around go up stay then down stay and back up and so on.

 

[crazysupra2JZ]

yeah it spudders. i have a video of it i'll post in a couple minutes

I can't believe you pulled the head without doing a compression test. With that said. Go do a compression test. Now that you've changed the gasket that should narrow things down abit. then get back to us. GL

When my turbo took a crapp it was spewing white smoke like that's what it was made to do.

Crank pulley making noise... did you check to make sure the bolt was tight?

I would doubt your valve stem seals would make a big enough difference as to whether or not the car ran. You'd be burning oil, but not flooding the cyl. They're (bad valve stem seals) typically only noticed at startup and after hard pulls, aren't they?

I'm confused... it was running like crapp so you have recently pulled off the head and replaced the headgasket?

 

[crazysupra2JZ]

i pulled off the turbo cause as soon as it happened i thought the turbo was gone. but it wasn't leaking oil at all. the shaft was fine. i noticed oil in the number 4 cyl exhaust port. i then checked the coolant and it was milky. the head gasket was damaged a little bit but not to the point that i was sure it caused the car not to run. i had a spare one anyway.

the pulley itself isn't making noise. it's in that area. this has never happened to me before. so i can't think of what else to look for to get it running again.
i have it to the point now where it runs but that's it. it's doing a lot better than it was when it happened. except for all the smoke.

Not enough smoke to be a BHG imo but it still might be, check if the rad needs to be filled, then see how much fluid it needs by filling it.. if its alot and your reservoir tank is still full its a BHG... might just be that you blew a ring on #4.. check for compression.

 

[crazysupra2JZ]

after i changed the gasket most of the smoke went away. and now it idles better. but something is still messed up internally. everything on the outside looks fine. wires, pipes, i even checked the fuel injectors. i'm gonna buy a compression tester monday cause napa's closed during the weekend.
here's when it happened.
