pecking noise
i think my old truck has finally done in something major. i was coming up elizabeth hill (long, steep grade around my house) and it just lost power and started hammering like i team of railroad workers inside the ol' 5.0 just went to work. like i said in previous post, comp was good, everything was good, and now i think it has had it. was able to coast it home and let it set for afew hours, noise has lessened, but still there, and you can feel the vib. in of all the odd places the intake, nothing in the valve cover. i can lay my hand on the valve cover and it feels like it is running just smooth as can be. how accurate is the factory oil pressure gauge, what psi does it drop out of normal opp. at? im a mess right now, this sucks @$$.
thanks in advance,
Daniel

Someone who seemed to be in the know told me it drops off about 7psi.
I lost oil pressure once in the Bronco on the highway and when I heard the racket over the stereo and wind/tire noise, I looked at the oil press gauge (a real gauge, not the fancy idiot light we have in our year trucks), it was falling to zero real fast. I shut it off right away and coasted to a stop, checked it out and found that the oil pressure sender extender rod (say that 5 times fast!) had cracked and was shooting oil out of the engine. It has had a valve train click ever since then but no bottom end damage that I could tell. I think the oil went down to around one quart cause there wasnt much that came out when I opened the drain. There was no metal in the oil iether.
Drain the oil and see what it looks like.
