Volks, I adjusted my valves last week and changed the oil/filter (replaced with a FRAM - smaller outside diameter, but same seal). Started OK next morning (cold - 35 degrees F), but neede a jump that night from work. While idling, a co-worker mentioned my oil leak - and it was running out of the oil cooler area. Looked like water in oil, but careful examination the "whitish" look was tiny bubbles. What the heck has happened? Did I blow the oil cooler seals? (probably) Isn't there some kind of pressure relief valve that bypasses the cooler when pressures are high? Any ideas or suggestions are welcomed. BTW, I have the engine out of the van now...When I removed the top tin, I noticed that there is black blow-by at the cylinder/head on the left side (actually, I haven't removed the right side yet, so it could be the same). This is a "new" rebuilt engine I was told and all looks that way. Is black blow-by an indication of bad heads? Bad head gaskets? Does it matter? Although the fan housing number matches the '72 year (CB), the block number appears to be from a 2000cc (GD). I guess I will have to remove a head and measure bore and stroke to determine exactly what it is I do have in this. Thanks in advance.
