OK, not a newbie, but didnt want to post this anywhere more specific, the car is a 92 Eclipse GS DOHC 2.0L non turbo 4g63 engine...I pulled the head off the car today to replace the had gasket and find and fix a strange oil leak(it wasnt leaking from the head gasket) its the front timing cover area, I got it all apart and lo and behold..I found the balance shaft belt broken, somehow it didnt take the timing belt with it, so now I have a leak down there, I have read the threads for the tensioner can leak...where else should I be looking? I guess I'll replace the front main seal while I am down there...assuming I can figure out what type of puller I need for the crank sprocket...any thought are helpful
 
Check the oil pump seal, its the one behind the balance shaft sprocket that's driven directly by the timing belt. I just spent all weekend chasing an oil leak and that was it. You also should need a puller for the crank sprocket, it should just pull right off.
 
ok, so just to review..gaskets/seals to repace while I have it apart...head set(for head gasket stuff, all upper gaskets) front main seal, oil pump seal, RTV on the tensioner bolts...anything else on the front end? I have new balance shaft and timing belts, head is getting re-surfaced, valve seals are getting replaced, do I have everything covered? trying to make this car last another 50k miles or so, but dont feel like pulling the block apart to do rings since cylinder wear is minimal and I need to get it back up and running sooner than that would entail
