Open ended question.
Engine has never had an oil leak until.....
During oil change about 2 weeks ago, when finished the tech said there was a slight oil leak that looked like maybe it was the gasket, could not say for sure. 1st time i had ever used this tech, previously i always stood under car with different tech who is great about talking shop and showing me as he is working. Did not stand under car this time.
Took car to excellent engine mech for check of leak source. He said the oil pan bolts were all fine, but he found a bolt on the timing cover was loose and leaking oil. The bolt that an allan wrench tightens. By a lot. Like half a turn, maybe even 3/4ths of a turn. Car seemed to not leak for a week, but now damn it's back.
I don't own a hoist so cannot say where exact leak source is, but it shows itself on the pavement about a foot in towards the engine from the front tire of the passenger side. About the size of a quarter, and it does not seem to continue once the "quarter" has formed in the 1st couple minutes after engine is shut off. Does not continue to leak when engine is off.
Any ideas what is causing leak, and better yet what a cure may be?
I know that is general, but just getting some ideas.
We will look at the leak again tommorow or Tues depending on mechs availability.
If you have thoughts on what to look for when car is on the hoist, please post!
