As for the sound at the engine end, it was a loose...

Re: Massive oil leak Yanmar 4jh2-te

So, just an update:

The patch in the pipe proved that the leak came from there so now I’m going to try and get a permanent replacement if that part.

As for the water in oil, I’m going to start...

Re: Massive oil leak Yanmar 4jh2-te

Sounds like an option…

I probably can order a genuine Yanmar pipe but it will probably be 50-100$ for a piece of metal with 2 banjos so I’ll try to jbweld it until I can find a good solution.

I’m going to attempt to jbweld it until the new one comes in...

Re: Massive oil leak Yanmar 4jh2-te

Hii everyone!

Thanks for your inputs!!

Re: Check before starting an engine after rebuild

Ok, then I might have to do an oil change when I’m done as I initially also sprayed the springs when they were stuck up…

As for the plunger shaft, I just woke up but they’re all still stuck so I...

Re: Check before starting an engine after rebuild

Ok, so probably with more pb, they should break loose at some stage?
