'93 Corolla with some oil leaks - Toyota Nation Forum : Toyota Car and Truck Forums

Hello everyone, I have a 93 Corolla that has a oil leak in the timing belt end of the engine, it might be the camshaft seal but i'm not sure. What i am looking for are other ideas on where it might be. Valve cover looks dry. Its a pretty big leak, a quart every 1000 or 1500 miles on the ground. At this point I have the belts off and the plastic covers. Thanks for any info or ideas..before I put on new stuff I'd like to think I fixed all leaks....

Crank seal or Camshaft seal.

Thanks Woz
Both the cam and crank seals are hard as rocks, so I'm replacing both. The cam has a slight groove in it so I will just have to see how that works out. The crankshaft has a repair sleeve on it, any idea if a stardard crankshaft oil seal will work over the old sleeve? Thanks again

Sorry, no idea. Never worked on this engine before.

The sleeve is thin enough that the standard part works, BUT It shouldnt be leaking!! If you cannot remove the groove from the cam surface with a very fine emery paper, install the seal slightly inboard or outboard so the seal lips miss the groove.

Your major leakage is the crank seal, but you may have other things leaking too.
