So I had my motor replaced 1k ago, before that my old motor had 200k and leaked oil like crazy it also didnt help that the crank was moving back and forth in the engine grinding the block down. Now onto the problem I had the motor replaced and rebuild the head and carb, it runs great but still leaks oil I took it back to the shop and the guy said he doesnt know why it whould leak he only put 5qts of oil <img src="/forums/images/graemlins/rolleyes.gif" alt="" />. As far as I know my trooper doesnt take 5 qts more like 3.5 or 4. I have already check the PCV valve so thats not plugged, could overfilling the pan cause seals or gaskets to blow? another question is can I advance the time for better topend power.
