New head gasket leaking, what next?
On my '91 M20 I Just replaced my head with a new head casting, cam, valves, etc... all work done at a local reputible machine shop.
I got it all back together, runs like new. Now a week later after about 200 miles I notices a small spot under the front of the engine. It's leaking oil at the head gasket, right behind the distributor, a very small amount. Changed the oil, No coolant leak. Never overheated either.
Any advise? Start over? ugh... The amount of leakage wouldn't amount to anything more than an aggravation, but it irritates me that after all that work, it isn't right.
I polished the top of the block clean, and the head was newly machined. I torqued properly, then 90 degrees, then 90 degrees again.
What could've gone wrong?
