Well both me and my brother have been in the dsm game for a year or so and working on our cars together. We've gone through a lot of crap but the fun of having this car makes up for it. Anyways we both were having some problems and decided to do some headwork at the same time. He's been getting most of his info off this forum and I figured I'd join too.

Well anyways heres my current situation. My turbo blew so I put an Evo III in. Then we did the head work due to some oil being burnt or so we think.

Right now I have two main problems.

1:

White smoke comes out the exhaust at idle. I havent gotten to drive it much to see if it comes out while driving. The coolant was recently filled and now the reservoir is a little low but I'm not sure if it has to do with it being lost or just being filled throughout the system. It seems like the oil is a little low but thats hard to tell also because of the same reason. I've checked the PCV valve and it works fine(only blows air through one side). No boost leaks from when I checked from the turbo but I still need to check from the throttle body. Also I will check the intercooler piping for oil asap. Not Head related or valve seals or anything. Just had them all done and the compression is near perfect. My brothers having similar problems but we both cant't figure it out.

2:

Idle is lumpy...like it skips a beat. Timing is good and no boost/vacuum leaks. The vacuum does read 10-11 hg where it used to read 20 before the cylinder head job. Will check the BISS oring soon as well as maybe clean the throttle body but 10 hg's difference seems like a lot. My mbc seems to be working well and have never had problems with it.



Any help on either of these problems would be great. Feel free to pm me or just leave a reply. It's cool to finally be part of the online dsm community.
 
Just cause the turbo has no shaft play does not mean that the oil and coolant seals in the turbo are not shot. As far as the oil leak tighten it up, if it wont use some thread locker, and/or retap the bolt holes and clean them out. Since oil was in the coolant system you need to flush it to get all the oil out and start with fresh coolant to see if the porblem was fixed. Oh and the black on the turbo exhaust housing is normal cause its carbon thats being removed from the engine after it fires fuel/air, but it should not have an oily feel to it or smell like oil. It may seem a lil oil but it is ###### gas and the smeel of that with confirm its gas but does not rule out the oil. So do a compression test. When you took the head off did you check with a feeler gauge to see if the head was warped, head suface was deeply scratched, etc?


Also I did a flush through the coolant and put new coolant in right after the head install. Should I flush the engine with an engine flush? Also I never did pressurise the block but didn't see any cracks. I cleaned the intercooler and all the lower and upper piping. Should I put the turbo on and start it up again after doing the flushes?
 
Sorry to triple post but I need some help. I am in a really bad situation right now this being my daily driver. Should I check 02 housing side of the turbo before I put everything back together? Also How the heck do I know If turbo seals are blown or not? I'll do a search but info quickly is needed as I am running out of light. Also is it possible it could be my block? Please respond as soon as possible so I can work on this thing. Thanks.
 
Going to go a little different direction. Have you checked the vacuum lines at the throttle body if they get changed around it will give the engine fits. DAMHIK!!:coy:
 
Under the hood has the diagram if not pepboys or any other chain parts store pick up a service manual for the 2g it will have it in there.

Ive got a Haynes or Chilton or both. Ill check it out. I'm pretty sure they are all good. I already discovered one earlier that was wrong which is possibly the culprit. FPS line was teed into the wrong one and same with the intake manifold one. I fixed it. Hopefully that fixes the idle problem, but there's still the dreaded smoke issue!!!!
 
I'll do a search on what BLT is. LOL Alternator fuses are good but I'll see if I see anything in the wiring. As for the torquing of the head we did a compression test about a week ago and It was the same. Well I think the seals would be good but I guess that's a possibility. Wouldn't that be shown with low compression though??

BLT = Boot leak test. I hate acronyms too, I guess I forgot.
It wasn't an alternator fuse, I think it was the rectifier diode. Bad fuse = no power at all, but a bad diode means low or pulsing power at lower RPM. I can't remember if it's the diode that causes the problem or another component, but it's not the fuse. The symptoms are different.

If there was excess oil in the pistons (from some leak), could seal up bad rings and give (misleading) higher compression. That's quite a long-shot though, it's just a thought.
 
Have you done any of the suggested stuff that was typed up or searched for any more answers?

Yes I have done almost everything. I just need to put everything back together and see how it goes. I'll update when I've done that. The only things I haven't done are the electrical stuff having to do with the lights but thats not my biggest concern right now.
 
UPDATE:

Car is back together and no more smoke from exhaust!!!!!! However the lumpy idle remains. Also after letting the car warm up we noticed smoke coming from the radiator. Also the fans didnt kick on and it was getting really hot. However the temp gauge in the car read normal. Any ideas? Were thinking of replacing the thermostat.
 
I had the same problem, but I had white smoke coming out of my exhaust. It turns out I had a bad head gasket and coolant was flowing into #3 cylinder. The head was also warped pretty bad. I don't know if that would be your problem or not. Since you said all of that was previously checked.
 
I have the same problem, no boost leaks, 160-149-160-160 Compression....Don't have the idle problem but I am only registering 8-10 in vacuum as well... TONS of smoke coming out of the exhaust..... turbo had tremendous amount of shaft play so I am replacing it as we speak.... hopefully that fixes all the smoke :thumb:
:dsm:
 
I fixed my smoke problem. My idle is crap though. Im gonna put a video up as soon as I can...hopefully that will get some more help. I cant turn the AC on or it gets even worst too. :( the idle will start at about 1500 then set down to 1100 and bounce around in that area a little. Drives great other than the idle but annoying as hell.
 
I fixed my white smoke as well, it was the turbo, so I upgraded to a 57 trim :thumb: and no more white smoke! although the housing on the turbo is soooooo big that I am still having problems mating the exhaust manifold with the block.... bad exhaust leaks, so it is still not up and running yet..... but it runs ;) ..... I can't wait to get out and see what that turbo has in store for me since I upgraded from a 50 trim..... :dsm:
