Warmed up the car 5 minutes prior to starting it up again and recording.When i first started it, i heard some weird clanking noise that came from the engine but died out after 5 minutes of warming up. Also saw alot of white smoke coming from the exhaust manifold but went away also after 5 minutes.heres a clip of starting the engine for the 2nd time. u will see that after steeping on the gas a bit, the idle drops pretty damn low. the other day it dropped so low the engine shut off. heres a clip of the engine, let me know if u see/hear anything out of the ordinary on how to make it pur besides buyinga new engine?btw its a 96 b18b1 recently rebuilt with new valve springs/retainers. tahts about it. about 10k mi on it.
