Engine Oil Cooler

[ccm911]

Hello:

Has anyone ever resealed their oil cooler(on engine) with the engine in situ?  I have ordered the seals, and am hoping that this will not be a large job.  I read the tech article on Pelican written by Steve Stomski, but it was kind of vague.

In order to make my car oil-tight once again, I plan to replace the O-ring on the engine thermostat, replace the valve cover gaskets(along with a valve adjustment), replace an oil line, and also replace the axle flange seals on the trans.

Is there anything more annoying than a leaky 911?

Thanks.
