This is my first post. I am in the midst of a 24 month tune up. I had drained the radiator and engine block and ran water through both until it was clear. I noticed worn belts and removed the radiator to change them all. As I was removing the lower hoses a reddish oily substance came out of all 3 of them. Maybe a 1/2 cup in all, maybe less. The oily stuff came out before the rest of the coolant drained.
I have had no overheating problems, no sign of coolant in the oil or oil in the coolant, no oil loss problems (or coolant loss for that matter.) I repaired a head gasket leak around 20K miles and 2 years ago. The truck has run well since until recently when I began having hesitation problems and even stalling after running around town for a couple of hours.
Codes pulled were 13 and 22--the wire from the distributor to the ignitor was getting hot. All 4 plugs were sooty and the the inside of the throttle body was coated with black tarry stuff. Compression from front to back: 155, 150, 145, 140. Hmmmmmm.?. Head bolts have not been checked since the head job. The head gasket leak at that time was in the very back of the engine.
I replaced the fuel filter and will be replacing the O2 sensor, plugs, plug wires, cap, rotor and taping, re-routing and heat protecting the ignitor wire and testing my coolant temperature sensor and tps tomorrow, but...
The immediate question is WTF is that oily stuff coming out of the lower radiator hoses? It was mixed with coolant, seemed a little reddish and could have been AT fluid. Or not. Any ideas? Anything else I should check before flushing the radiator/block putting in new coolant, etc. While I still have everything apart?
Thanks in advance,
