On to the boring job of scraping and washing away the accumulated crud from the block. I can’t get the block outside to use a pressure washer and I’m not sure that some of the water wouldn’t make it’s way into the engine.
I used an old paring knife and a razor scraper to get the main part of the grunge off and then using a toothbrush, parts solvent and rags, it cleaned up not too bad. I’m planning on painting the block, but before that I’ll have to go over it again with a small wire bush and parts solvent and then finally with paint thinner.
Ditto the opposite side. I’ll remove the ring gear and then do the back and then the front of the engine as well.
Valve covers off and a peek at the rockers. Fairly clean and oily on the right side.
Left side not so oily or clean. Lots of carbon. I’m thinking that after 100K+ miles the wear on the engine components is lowering the pressure and not enough oil is getting to the top of the engine.
I didn’t want to take the pan off, but best laid plans… I have a new high volume Melling oil pump that I bought for another engine. I’ll get that in and it should get more oil up to the rockers.
