Thanks Cobber, it gives me at least a new line of inquiry about finding the source. Do you know where I can find where the breather is on the K series?

Hello friends.

Im hoping someone can assist in figuring out what the issue with my 1.8 135 TF might be. I have had a cam seal oil leak for a while now, so forgoing my limited mechanical know how, took it to the MGOC to have all the seals replaced.

All done, 100 miles later, leaking again.

Taken back to them, seals changed again, they tested, all good.

100 miles later, leaking again.

Most confusing - I have been told it may be a blocked breather that is causing too much pressure in the top that is blowing the seals - sound about right? My only other thought is that there may be a nick on the mating surface, but that wouldn’t explain the delayed leakage. Thank you in advance for any knowledge you may impart!

Cat tax for attention.
