150 HPDI LZ150TXRY Oil Leak Please help!

[chapin123]

Hi, I owned twin 2000 Yamaha 150 HPDI with about 600hrs. I noticed and oil leak coming down from the lower crank and replaced the seals. I taught I fix the problem , but the engine keeps leaking from same area. Any ideas on what to look for. The leak is clean oil and I already check the tank cap connected to the engine. The oil is coming from inside crank I think.






Please send your comments.

Thanks,

I saw clean oil in throttle body on both motors after removing plastic.

Now i am really lost.

Any ideas please!

two typical places it leaks.
1 is the engine oil tank cap. usually only when tilted.
2 is the seal around the airbox.

oil standing in the throttle bores is normal.
