Engine rebuild after failure, check piston squirters
 

Rebuilding engine after PO has rebuilt after #6 damage.

Exact issue unknown but suspect rod bearing failure originally.

Found this in one of the piston squirters, stuck partially open

Might have been why PO gave up on engine as it was said to have piston slap.

It had many more issues, but I'm sure this didn't help.

Is that silicone or plastic?

What a nightmare

can this be done without splitting the case ?

The tubes i think but the squirtter heads themselves require splitting.

No, the case has to be split.

Ok thank you. Is there anything to do with them when case is still together? Maybe insert something pliable yet soft to confirm it's at least not clogged at the tip?

If that was in a squirter, what other debris is in the rest of the motor?

I think I acquired this after the second tear down.

I believe the first failure must have been #6 rod bearing -- as the case
has signs of damage where a connecting rod hammered the bore.

That work had been fixed -- and the PO had the engine rebuilt.

Shortly after that rebuild -- he had it torn down claiming it was piston slapping,
but over the past few years of getting ready to rebuild this engine again
we found numerous problems.

The piston squirters were the last thing that we had looked at prior to reassembly
and I'm glad my mechanic tested each or we might not have noticed the oil squirter issues.

6 new ones going in today.

Nice pic but any chance of getting some pictures of the case and the affected area ? SmileWavy
