Lost oil pressure, now knocking sound.

Ok, long story short.

driving back from school in my 72 e-200, 302 ford power, when the oil light comes on. It ran for a few moments before I shut it off, and pulled over. Pulled the dipstick, not a drop of oil. I checked the oil about 75 miles before, and it was full. The ENTIRE bottom of the van is covered. Anyway, I filled it back up, started it. No oil light, but there is a knocking sound now.

Could it be a rod knock? if so, that means a set of bearings, correct? Any other thoughts on what it could be? any help is appreciated.

Knock

Well if it a rod bearing you will have to do a tear down. Find out which rod bearing spun. The rod end will also have to be resized. Also have the crankshaft checked. If ok install new bearings. Are you sure it's a rod or could it be a lifter? That would be a lot easier. If you have a lot of miles on the engine it would be a good time complete rebuild. Good luck.

From what you describe, a rod bearing has spun. You'd be darn lucky to just get by with a new set without having to do a bottom end rebuild. Might be cheaper to just find another used engine you can drop in over a week end if it's your daily driver. I hate to be the bearer of bad news, but I've spun a few myself and haven't got lucky yet.

X2 you would be very lucky to spin a bearing and not have to do a bottom end job. JMO

Its not my daily driver, being as I have another vehicle. I think I'm gonna look for a roller cam block (80's) in either 302 or 351.

About what does a roller cam 5.0 liter go for these days? Im talking like what the fox body mustangs/crown vics had in them.

Even though it's a moot point, where did all the oil on the underside come from?

I was wondering the same thing, were did the oil go?
I wouldnt just replace the bearings either since that most likely doesnt do the trick. I had a similar issue and I just got me a good used 360 for $300
(Mopar Truck) and dropped it in. Worked well for me.

Im not sure where the oil came out of, but its everywhere.

Im looking into finding a short block before too long. I think a 351 would slip right in where the 302 did, but im not sure.
