engine smoke from dipstick Reply #4 – April 16, 2006, 03:30:18 AM lol the mechanic told me to floor it he was wrong i was sketchy about that too cause rebuild is like if its new and you have to go easy on it but he told me to floor it. So if i drive my car at normal speeds for a while it should go away? And does anybody have a spark plug diagram for a 91 tbird? thank you guys for the help. Quote Selected

engine smoke from dipstick Reply #7 – April 16, 2006, 11:34:19 AM tbird232ci is right. ya can't beat on it during break in. and break in is usually what 500 miles or so? im not too exact on it but the reason why your getting smoke is due to bad rings due to improper break in. Quote Selected
engine smoke from dipstick Reply #8 – April 16, 2006, 12:09:41 PM If any kind of smoke starting coming out of my dipstick and oil vent cap, the first thing that comes to my mind is a non-functioning PCV system. While I don't know all the exact components that operate that system or exactly how it works---have you checked that? If the crankcase is venting smoke that tells me that the air pump and/or other hookups are not connected or working. If your engine is otherwise running fine, an early hot dipstick condition relates to several factors--how much you gunned the engine and where you live (hot or cold climate--sorry I did not note your location). As a novice mechanic, I would say the first thing to get hot in an engine is the oil in the oilpan (elementary?). Hopes this helps. Quote Selected
