New Turbo, Replacing Valve Seals

[Grescht]

Ok, so i bought a new turbo. The Turbo seals in the 14b went bad. I'm in an odd place right now. I was going to replace the valve stem seals but i dont have a spring compressor. I'm at a place now that i need to get the car done. Should i wait and put the valve seals on? or should i put it back together and see how it runs? The only reason i think its valve seals is because it smokes blue under WOT. NO SMOKE AT IDLE EVER!!! What should i do? im stuck.

yeah, just looked at the head gasket... looks like oil is coming out. i guess when the turbo blew it took the head gasket with it. :/

It could be a number of things causeing your car to smoke. Bad valve guides, bad valve stems seals, bad piston rings, an out of round cylinder. You need to do some more tests. A compression test and a leakdown test are in order.

You have that backwards. If it's your stem seals, then it will puff on start-up and at idle.

At what rate are you consuming oil?
When the turbo seals when bad in the 14b, did it puke oil into the IC pipes?
Is it still smoking with the new turbo installed?

Yeah, i did have the backwards. Compression is 170,170,160,179. The motor has 10k on it. Did a leak down, kinda. didn't have a gauge, used the compression tester. I has the Cams out and this is what happened. When i pressurized it to 60psi. I heard air going everywhere. Nothing is going out the throttle body, nothing out the exhaust ports, nothing going into the oil pan. i was very confused. As i was putting the Valve cover back on to begin reassembly because i couldn't do the Valve seal job ( no compressor) i saw oil seeping out the Head gasket. so i went ahead and pulled the head. Could the air i heard moving be coming out of the head gasket? I really dunno what to do now. I've got the head off. I'm definetly going ARP studs. I'm pressed for money. SHould i do a valve guide and valve stem seal job? im wondering because it never smoked at idle. ever. only during accel. and some people said it was white smoke. I saw blue but i'm not sure. Should i do the valve job? or just put it back together with the new head gasket and see if it still smokes. It just Ran really bad before i tore it down. Oil consumption rate actually wasn't that bad, but that was with some conventional mixed with synthetic. Yes, when the turbo crapped oil did get thrown into the LICP, but not a ton, just a little. (turbo still boosted though, lots of play in the shaft). I haven't gotten the motor back together to see if the turbo was my only problem. so hear are my main questions....

1. Should i do the Valve Seal and Guide Job? or (I'm pressed for money and pulling the Valve cover back and T-belt off isn't bad)
2. Should I put it all back together with the studs and gasket and turbo and see how it runs?
3. Where would air go if not past the rings/valves? (during leakdown)
4.When i revved it, it seemed like white smoke to me, only under hard revving though. head gasket?


One more thought. when i did a BLT before any of this. I did it from the turbo inlet. There was air going into the VC and pressure on the oil cap. When i did it from the LICP there was still pressure on the oil cap. When i did that leakdown, there was no air that i could feel coming from the intake or exhaust, probably because the mass amount of air I have yet to figure out where it went. so still a possibilty the valve seals are bad?

BTW all the valves are a tanish whiteish color, little bit of carbon.

kinda sounds like headgasket, but it could be something else, i would replace the seals anyway. You can make a spring compressor for like 5$, probably free if you have a garage with some tools in it. it'll take an hour more in stead of repeating the process again.( i hate doing things over right after). that way the seals are eliminated and if the problem persists a leakdown should tell you for sure whats up. If you can check your guides i would do it aswell because it dont take long if the springs are out.

DO you have a link to the instructions? or can you explain to me how to make one. That would save me a bunch of money because i already have the seals.

I am assuming that when you said you looked at the head gasket the head was off the car. You will also need a friend with some steady hands. I don't know where i saw it but basically take a spark plug socket(it will be wrecked as a spark plug socket after) and cut a little lass than half of the socket wall out so if you looking at the bottom hex part of the socket straight on it will look like a U. This is so you can get a magnet in to remove the keepers.

Take a clamp a wood clamp will work, a big c clamp would work, something that will reach around the whole head. put a rag on the bottom face of every valve as you go and clamp from the valve face around the socket which should be on top of the spring and retainer. stick a magnet in the cutout in the socket you made to remove the keepers. I hope you can understand this all in words. It would help if I had a camera but i dont sorry. If you have any questions ask.

I think that either a Autozone,Advance,or Orielys rent spring compressors. I'm not saying this won't work, but this seems like a big pain more than anything.

turns out my parents are gonna pay for the valve job for christmas! so I'm getting the valves ground, valve guides, valve stem seals, pressure test. Cleaning. Remachined head surface also. new gasket, arp head studs. Port and polish on intake and exhaust. Its gonna be nice. Should I replace anything like the knock sensor while i'm in here?
