It always surprises me to see an oil leak because with the gapless rings I have a hard time telling the difference between oil, fuel, and other leaks because the engine oil isn't soot black... I thought the steering damper was leaking. Turns out one of the oil cooler hoses is leaking at the cooler side rubber crimp.
This isn't the ordinary oil cooler line failure. It was one of the first things I replaced on my 1993.
It outlived the original engine and was exposed to high towing temps all the time.
They then were bent slightly when the oil cooler was broken while hitting an elk. outlived that truck.
They outlived the engine in the next truck they were put in as the engine was worn out.
The 6.2 replacement engine was hauled out for new rings, heads, and pistons.
2 years and 50,000 hard hot miles.
So with the 32 degree weather we have one leaking bad enough to drip on the ground. This is a real red flag - a drip.
So I will say GM has improved the lines since 1998 when they usually didn't even make it out of 12/12 warranty on my 1993 gasser. But I hate the clips on the engine enough to recommend a thread in kit like PMD Cable sells. I have spent way too many hours trying to get the clips and lines off the engine and find the clip after it goes "boing!"
Sigh! Here we go again...
