I got a big problem. I got an 88 Blazer 4.3. The oil pressure had been down around 20 psi at idle, then it was around 15 wile driving. It's been that way for months now. I put off and put off changing the oil, cause I never had time to change it. This motor is a remanufatured motor, bored 40 over I believe, but my father has been running 10w-40 in it since we got it. Well, since it was way over due for a change I ran some motor flush through it then drained it out, and the shavings that came out of it just shined like gold. I got a wild hair and decided to run 10w-30 along with some engine restorer to try to raise the oil pressure. I got it filled up, cranked it up, and the oil pressure needle was pegged at 0. At first I thought the sending unit may be bad, but when she started knocking home sweet home, I knew it was serious. I told my dad that I changed the oil type and he says you're never supposed to do that. He called our "other" mechanic and he thinks it's either the oil pump or the camshaft. I want to see what the gearheads have to say before we fork out the money to rplace these things.
