Re: Water in oil

Is there a reason you have your cap lock on?
makes things harder to read.

Do you do the leak down test like you were told before?
If so what did it show?

Have you found any water in your fuel?
What pressure does you fuel run at the point it is in the cooler?
Is it higher than water pressure?
I would think so if this is a injected motor, and if it is higher on the fuel side it will get fuel into the water not the other way. But that is just an opinion

Sorry about the caps. Leak down test did not show any malfunction.No water in fuel as tank was drained and fresh fuel added.Going to check fuel pressure today and snoop around that area,thanks
