Oil return line

Hello Fred

You need to do the oil system pressure test as shown in the installation manual.  If your crankcase pressure is too high then oil seals will weep.

The installation manual also shows the correct size for lines on the system.  I suggest a 13mm ID line (½ inch) at the least.  Be sure that your fittings are not too small also.  The most common problem for high crankcase pressure is a restricted return line from the crankcase to the oil tank.  

Cheers

We have Checked the pressure well within limits on the ground so maybe under load it is higher? Replacing the seal then recheck.

any other reason to push the main seal out.?

the banjo has a smaller nipple to match the smaller hose same with the tank fitting.

thank you for input
