What the hell did this thing go through? The insides look as though it was set on fire and then submerged in a lake!
The lifter valley was full of oil/charcoal deposits the size of golf balls! The liquid sludge was thick, and covered everything inside valve train as well as caked the exterior. I can’t wait to pressure wash it and then have a machine shop tank it.
It is a 4 barrel and the intake appears to be in reusable condition. We were able to get the engine to rotate manually so nothing was seized. We discovered a flat tappet cam so we will be inspecting and measuring the cam thoroughly. The rockers and pushrods appear to be fine, but we’ll confirm the geometry upon re-installation. The spark plugs all yielded nothing but more sludge 🙁 We will do as much degreasing and cleaning ourselves as possible, but we plan on taking the block and heads to a machine shop to have it hot-tanked to ensure all the oil passages are cleaned.
