540 Issues
 

I did a leakdown on my motors coming out of my boat...it's been all downhill since then.

Guess how many hours are on these bearings?

Mains

Rod Bearings

I'm gonna guess you were hoping for quite a few more than you have on it before you got this deep

They look like they have 300+ hours on them, I freshen my blown 540 every 120 or so hours and they have always looked like new (h series running on a 4340 crank that is permatoughed ) running about .0028-.003 main and .0033-.0035 main or so clearence, Smitty

Doesn't look good, any gas in the oil ?

ya running too rich will do that

I never had gas in the oil. They never ran really rich either. I'll add some pictures of the cranks in the morning.

Any chance of detination ?

they dont look that bad to me,im not good at guessing,how many hrs do they have,and what brand and weight oil do you use?

i forgot to ask,what brand are the bearings?
