A friend of mine told me the other day that when I started my quest with the fully rebuilt engine that has just 3000 miles on it, that he saw a small puff of blueish smoke...I asked him was he sure it had a blue tint he said yes. So I checked it and it does have a quick puff right as it fires up...but nothing after that. Is this something that I need to worry about or not, thanks for the input.

I've noticed that my car has a pretty good engine stumble after I give it throttle and when it goes down back to idle it dips below 1K rpm and stumbles like it's gonna die. Now it's done this for awhile before since I installed a lightweight flywheel. But now that I've deleted the balance shafts it seems to be worse. Could this be a combination of no balance shafts and a lightweight flywheel or something completely different? Any remedy to correct this or lessen the issue?

Help! I need a sunroof crank assembly. Does anybody have one I can buy?

Just received my mookeeh 3in downpipe and now a I'm curious what to do about the O2 sensor.. what have you guys done? do I just buy a universal one and crimp it to the old wire?
