[TR] timing cover leak?

[DAVE HOGYE]

Hello Peter,
The first thing to do is perfectly clean the engine, especially around the cover.  The leak will be much easier to pinpoint.  
I have seen a few covers with holes worn into them from the chain tensioner.  Over time, the hole gets bigger and leaks more oil.  
Leaks could be from gasket seal failure, or crank seal to.  If you clean everything first and it's leaking that much, you should see the leak after a short drive.  A dusting of a powder could help.  
Have you checked the tightness of the cover fasteners?   Loose bolts will allow the gasket to fail.  The cover will need to be resealed.  
Check the oil pan bolts to, being careful not to over tighten.

Head gasket does weep - about a quart per 6,000 miles - copper head gasket .093 thick required because of extensive shaving. It has now gone to a quart in 1,000 miles which is what it was before rebuilding diagnosed leak as timing Cover seal. Leaves a drip on ground when stopped only about 2-inch in diameter. Seems really small for usage, last time left much bigger drip.
