Britbike forum Forums Thread Like Summary - Need help evaluating head gasket oil leak.

A65. I removed the head to address coil binding. Upon reassembly I annealed the copper gasket before fitting the head.
I've put probably 100 or so miles on it since.
I have not re-torqued the head bolts since reassembly.
Now I'm getting a bit of oil seepage from the back of the cylinders around the push rod tunnel.

I know I should re-torque the head after a few runs. Is it reasonable to expect that tightening the rear head bolts will address the oil seepage?
Or should I take it apart and evaluate?

Thank you

do a compression test and see if it is anything more than a cosmetic issue

test comp before and after torqueing ..........i have never bothered annealing head gaskets sometimes annealing makes them to soft so definitely re torque if you have used an annealed gasket

I take it back enough so that it is free to turn by hand, you don’t want to take it out again.
