oil leak?

Anyone know how to fix an oil leak from the device where the oil filter and cooler connect to? The leak is from the lower back corner where there is a quarter size dial of sorts. The dial can be adjusted but makes the leak worse.

oil leak?

Forgive me Im not too familiar with the M20 but There should be nothing more than plain o rings sealing the lines to and from the oil cooler on those motors. Is it leaking from one of the lines?

Re: oil leak?

You must remove the snap ring holding in the dial, as you called it. Now just replace the internal o rings. Look at realoem for a picture of the parts involved.
