Okay, the K5's climbing abilities are awesome. I've climbed hills my buddies swore couldn't be done. My question is how steep is too steep when going downhill in a 90 K5 w/ TBI. Uphill is no problem, but I'm worried about running the oil pump dry on steep downhill grades (dropoffs). Is this something I should be worried about? I can shut off the engine IF the oil pressure gets too low, but there goes my power brakes. Anybody?
