2022-05-29 Oil Passage Leaky

Part #24

Leaky at rear O-Ring

Had tough time breaking it free. Initially used water pump pliers with jaws wrapped in electrical tape,
then tried 'tapping' it free using a small ball peen hammer. Did not want to damage the powder coating.

No luck, so on to Plan B. 

AKA screw the powder coating! 


Used a small butane torch to heat the powder coating that had sealed the junction.

A little wiggle and waggle and she broke free, a very good thing as other wise the exhaust
would have to be removed and it's a royal PITA to stuff all those headers into the collector.

And if I did that, would drop the headers and send them off to Jet-Hot for ceramic powder coating.

And if I did that, would install a new water pump mechanical seal.

So pretty happy to avoid all that work, for now!

Turns out there are two O-Rings. The leaky one is up front, 25mm.

The parts fische indicates qty 4 22mm O-Rings are used on the oil pan assembly. 

Ordered OEM O-Rings, and the 22 mm units are NOT even close. 

This pic of the oil drain plug.

Same issue with the other two locations where the 22 mm O-Ring is used.

OEM part. Fail.

Top one is new, too small.

Another view.

While I was there, replaced front brake master cylinder rubber-thingie!

Much better!

I did replace the 25mm O-Ring, fortunately, it was the leaky one. It looks like my fix worked.

Many Thanks to KZ1300.com for replying to my silly questions!
