2000 5.9L spark knock
#31
Champion plugs which are going to have to be replaced regardless now because the tip is gone on #7, entire thing soaked in oil, so those and wires are definitely on the to-do list. #7 cylinder is down to 30 PSI and should be at 150...not sure what the problem is that is causing the lack of compression or how to figure out what the problem is

A leak down test can tell you more precisely where the leak is coming from, but oil and bad compression might be a bad valve guide seal or worn rings around the pistons
A leak down test is where you push compressed air into the cylinder, and listen to the various spots it could be leaking.
1. bubbles in the radiator/coolant flying out of the radiator fill port, blown headgasket or some other breach into the coolant system. (cracked block or head into the water jacket)
2. hissing at the exhaust pipe, leaky exhaust valve.
3. hissing at the intake/TB, leaky intake valve
4. hissing at the oil dipstick or crankcase breather: bad rings
