1972 500 Front of Motor Oil Leak Help!!!

Hello, Thanks for all your help guys!! Unbelievable what technology can do.

I have a new problem. After 2-3 miles of tuning after rebuild(not engine), I have developed a small oil leak on the front of the motor. It seems to be coming from a bolt just above the exhaust outlet on the left side of the motor. A loose exhaust nut has sprayed the oil all over my motor. It smells good, but I could do without the the smoke. The bolt on the other side in the same position seems to have a washer, where this one does not. I am going to look in my manuals tonight, but I thought I'd start here. Any Suggestions???

Good news/ Bad news!

Good news is you have oil pressure!
Bad news is it shouldn't be from the exhaust.

Check out the oil pressure switch while your at it.

It coming from a bolt above the exhaust. A loose exhaust nut has sprayed it around. Thats how I found it.

I do believe I have a head gasket leaking. Possibly a gasket under the cylinder head. Why not do a top end rebuild. I've always wanted too. Thanks to Lunmad, I am not scared.

If its a headgasket leak,put your hand near it and see if you can feel a gas leak.Alternatively,spray it with penetrating oil and see if it blows it around

BOTH!!! Push rod tubes are leaking and head gasket. Guess I should order that gasket set.....fun, fun, fun!!! A fin on my head has cracked off fairly close to one of the head bolts. I don't know if it's salvageable?? Anyone have an extra 500 head lying around??

It'd be cheaper to get the fin fixed

If you have the bit, a decent welder can fix that.

if not, it's harder, but do-able
