Pulled head 02 di is it ruined?

[pinktexasbred]

Got time to take it off and this is what it looked like.

It is hard to tell since that is a very lean burn engine but it does look pretty worn.
What compression numbers were you getting? You did check before you pulled it didn't you?

 

[pinktexasbred]

I was able to and got a 20 and 0. What else am I removing before I get to pulling the actual piston?

 

[mikidymac]

How many hours? A high hour crank will not survive s new top end.

 

[pinktexasbred]

I do not know for certain I was told around 130

One piston moves very freely but the other is stuck

 

[mikidymac]

What oil was being run in that ski?
If it were mine with that much wear on the pistons I would replace the crank.

 

[pinktexasbred]

Yes oil was in there, there was also some white creamy buildup inside where the water cools the head. Is there a reason why one of the pistons is stuck? Aside from replacing how would I pinpoint the source of the problem so it doesn't happen again? Thank you

 

[mikidymac]

What brand/color of oil is in the oil tank?
So do you mean one piston won't rock back and forth on the connecting rod? What do you mean stuck?

 

[pinktexasbred]

I use the xps synthetic oil it's in a yellow bottle, where would I check to see he color of the oil? The one piston will not move on the connecting rod. That's what I meant by stuck sorry

 

[mikidymac]

So yes you are using the correct oil. If the piston won't move on the rod then the wrist pin bearing is seized and the rod is probably galled too. This will require replacing the crank.

Is there a way to visual confirm it is a seized wrist pin bearing and the rod? Thanks again.
