I had a mishap with some water that rendered my engine useless. Snorkel worked great but I was underwater for a long time with the jeep running and the drink slowly seeped past the seals into the crankcase killing my cam, main bearings, and piston rings. So, I need to put in a replacement. I have a spare engine with 100k miles on it but the service life of this engine is unknown.
As to address common issues while the engine is easily accessible I have decided to chance the oil pan gasket, timing cover gasket, rear main seal, intake gasket replacing the currently cracked exhaust manifild with an uncracked unit, as well as the valve cover gasket.
Some questions though...
How do I tell if the timing chain is alright? I've never heard of problems with these at 100k but I figured I should check it anyway.
How do I know if there is too much wear on the cylinder walls?
If I take each rocker off and remove the pushrod one at a time to clean them will this affect anything? I'd reinstall before removing the next.
How sould I reintall this stuff...with a little layer of clean motor oil?
Is there anything else I should do while I'm in there?
Thanks
