Well , I checked the rad and the oil , both look fine , no odd colors to them , still look like new in both.I took the plugs out , a couple were a little carboned more than the others , and some had a little brownish/white on them and otherwise looked ok.I tried a compression test , but I have a cheap thing that you push into the hole , and as soon as it hit a little pressure it spit it out.So , all I could get was around 90 before it spit it out.Would probably work better with someone holding int in <img src="/forums/images/graemlins/smile.gif" alt="" />

I also took the opportunity to change the plug wires to a better brand , but still 8MM , these should work better with my MSD ignition.Starts and runs like a top.Looks like normal exhaust coming out the back , no odd smells or anything.It seemed to be only when I had it floored that I saw the little smoke coming out.I did put some new gasket things in my headers , but I think they are crap , I have another set I will put in and see if that helps any , they are the copper ones.

Other than that , thats all I know right now.Would roller rockers cause it if they need to be tightened a little more?I did it till they stopped jiggling , but maybe they can use a hair more tightening down.
