I removed the head to replace the head gasket. it was quite the mess in there.
1) what is that goober on the side of the middle piston in the pic below. it flaked right off and underneath didnt seem rusty. theres a tiny bit of crap below that looks like rust but i'm not sure....looks like coolant could have dripped in while it was sitting for the last 11 months and sat there and rusted....your thoughts?
2) is there a way i can tell if the cylinder walls are tooo worn? i dont feel much of a lip when i run my finger on the cylinder wall....there is one, but its pretty light...feels like a scratch more than a lip....if that makes sense.
3)can i re-polish the cylinders somehow to clean up the rusty stuff from #1 above? maybe a thing for my cordless drill where i don't need to remove any more of the engine...........just to clean it up a touch and make it "good enough for the bash"
4)how do i clean the top surface there with the valves and pistons and all that? are there any cleaners that are meant for that? I don't want to spray some cleaner only to have it pool around the edge of the piston and cause a problem when i start it up next. or have it get under the valves and get blown into the engine during start up....or something...
5)anything else i should do now at the same time since it got it all open and stuff??
I'm hitting the cylinder head with all sorts of de-greasers and gasket remover.....since theres no moving parts there, it doesn't worry me.
the pattern of the gasket re-enforces my belief that it was the cause of the smoky engine and oil in the coolant........hopefully that was the only major problem.
Once its back together I'll do a compression test.
share the wisdom!!
