Alright, here's my problem... ( see bottom of post for reader's digest version**)
Just got a built 6-bolt swapped into my 95 GST. Shortly after, I blew the headgasket (only thing that wasn't aftermarket on the entire engine, go figure ) so it was replaced with a 4-layer metal HG from Mitsu.
After changing the head gasket out, I started the car up, and besides the idle surge I was experiencing prior to the HG blow, it ran good, and sounded good. Shortly thereafter (before I even drove out of the garage ), I heard a cracking noise, at which I turned the engine off. Inspected everything over and under and noticed a small hole in the lower timing cover just below the oil pump sprocket. Upon further inspection noticed that a broken piece of bolt had fallen into the timing cover during re-installation and had caught on the timing belt and shot out of the cover. Checked timing, its was still perfect, so the timing belt didn't slip off, but it put a gouge in the belt. So I went about changing the timing belt. Now I start it back up and noticed the idle surge, and high idle, again, but still sounded good. Turned it off and checked the timing again, and it was still perfect. So I mess with the idle settings on the MAF-T and then take it for a test drive to see how its running.
Now here comes the problem...when I come back I noticed a little oil around the oil fill cap so I take it off and find some white smoke pour out. After letting it out, I started the car again and check the oil fill cap again, and more white smoke coming out. It almost smells like exhaust. Now I'm aware of blow-by and what not, but it seems a bit excessive for a newly rebuilt engine. The only negative thing that happened was after the timing belt change I let it overheat slightly on accident due to the temp sensor being unplugged (totally different story), and the only other thing that is out of normality is that when I topped off the oil before I took it for a drive, I over filled it slightly.
**To sum it all up...
Freshly built 6-bolt swap into 95 GST, high idle, and idle surge experienced (beleived to ISC, problem is being diagnosed). Blown stock headgasket, replaced with mitsu 4-layer HG. Broken bolt put hole in timing belt after HG replacement, and Timing belt changed. Overheated car once, and oil is slightly over filled. Now experiencing white smokish vapors from oil fill hole in valve cover, but seems a little excessive for blow-by on fresh engine.
Any input, help, or suggestions would be greatly appreciated. Thanks for your time...
