Ok so i just got done installing a new dorman intake manifold.I start the car up and it runs fine,but there seems to be awfull lot of exuast smoke (white) after running the car for 15 minutes.would this be normal?when the intake blew the car was not over heated at all as it happened in my driveway.any thoughts?

check your coolant level immediately just incase coolant is seeping past the gaskets into one or more of the intake ports

did you torque down the manifold to the correct torque figures AND in order?

The coolant level has not really seemed to move at all (only 15/20 minutes of running) i did toque to the right figures and in order.Every thing seemed to go alittle to smooth.

once the engine warms up in the normal temp then shut it down and you have to retorque all the intake manifold bolts in sequence again. the resevoir level might not be noticeable drop because it doesn't take much coolant to produce the white steamy smoke.

well looks like i might have possible jumped the gun.I went and put 2 more ft #'s of tork on the manifold since my wrench kinda sucks.started it up and the smoke was cut in 1/2 from what it was, also it's 15degrese here.took it out and drove it and seems to run much better than it did its real smooth now.i did find a clogged vacuum port on the throttle body that think was causing the cel light to come on.scans showed it had a egr problem but i replaced everthing a year ago so

would that clogged port give it a crappy idol during the first start up of day, during the winter? say 20 out?but let it run fine once warmed. thats a problem that i have never been able to cure.

seems i took your advice before getting it if you know anything about the rough running during winter warm up please let me know.

a new plug might not be a bad idea seeing how yours been contact with coolant before and it might foul a little bit now.

not to jack your thread, but when I installed my dads intake (96), it worked perfectly, but then I noticed a dropping issue on the vac, more specifically on the brakes.. Happens rarely, but when it does, I have to press the pedal all the way down... Kinda scary.

seems like something about to let go. maybe vacumm related stuff like hose or sort like that?

Sounds like the brake booster possibly,I had a toyota that started doing that after replacing vac lines.the thought was, that i fixed a vac leak somewhere and it put more vac to the old seals in the booster causing them to leak or loose pressure.I'm probably wrong but thats what happen to that car and the problem was fixed.

Brake booster is not the master cylinder, right? or is it?

No its the part the master is connected to.Might be worth looking into if you have checked everything else.I have not eyed the one on my car lately.So i'm not sure it is set up the same as a toyota supra but i'm assuming so.

Thanks dude.. Will check it tomorrow.

A vacuum leak will cause a weird idle.. it will cause the car to "search" for the right idle speed, say 800rpm then it will go to 900 rpm, then back down to 800.. etc etc. check your vacuum connections and all your intake tube clamps to make sure you dont have a vacuum leak! =)
