I recently completed an H/C/I swap and was able to drive my car about 100 miles with no problems. I was coming up from my house to show it to my uncle, who didn't think I could do it. I had about 100 miles on the motor and 2 miles to go to get to his house when blue smoke came spitting out the back. Half the neighborhood came over and thanked me for clearing out all the bugs for them(thats what I get for knowing everyone) and they all gave me a hard time, but my uncle helped me find some garage space to try and figure out what was going on.
Originally, I suspected that the piston to valve clearance may have been the issue since the new heads I had installed had 2.02 intake valves, although I notched the pistons to get the optimal 0.080" of clearance on the intake side. The exhaust side was nowhere close to hitting, so I left them alone. I also used the converted solid roller lifter for the measurements.
I pulled my valve covers off and found the intake rocker on cylinder #3 had slid off of the pushrod and valve. I'm guessing the compression without the intake opening caused the oil to get pumped up through the piston rings and valve seal.
I need to find the answer to 2 problems, 1. What caused the rocker to fall off the spring and rod? 2. Did I cause any damage to the rings/valves/guides/seals with the piston trying to pump air through a closed valve?
Anyone have any ideas or advice on what I should be looking for, or what my next step should be?
