i just went out.. the dip stick dont leak but the oil cap does and I replaced the seal on it about 6 month ago.. I did call mitsu and get a new seal ordered.. I might double stack it for a tight fit. I dont see smoke behind me when I drive so I dont think I'm burning that good expensive mobile 1 oil. I might put some Marvlin (sp) stuff in it.. not sure... I DONT WANTA TEAR MY ENGINE DOWN... waaahhhhh if do, When i replace the rings and hone it out the wonderful cylinders can I use the stock pistons back in it.. Do i need a machine shop on any of this. hmmm i wonder if jeff's site has a step by step on this...
If your cylinders are in reasonably good shape, you can hone the walls so the new rings will seat. This can be done with a drill hone. The stock pistons can be reused. Depending on your car's mileage it might be just a temporary fix before you have to rebuild the motor anyway.
If the car isn't burning a lot of oil or fouling the plug, just leave it till it gets worse. Sometimes getting accurate compression readings at home isn't that easy. What I'm saying is, I would double check, before jumping to conclusions.
