What vehicle(s) do you drive?
1970 cadillac
Need a little help:
Got my 1970 472 together (again)
Was doing the cam break in, everthing sounded great, till i blew an external oil line that is.
Got it shut down and fixed the oil line.
The cranked it up to see if anything was hurt.
Heard what i thought was the very faintest of rod sounds in the area of number 7 cyl.
Pulled the oil pan and the 2 rod caps and took pics.
Please have a look and tell me your thoughts.
The crank looks good.

Have an aux priming pump. The toy truck will have months at a time when it wont be driven and ive never liked dry starts.
The priming pump gives approx 60 psi with a dead engine, and now i know to run a steel line, lol

Jerry, I don't see anything on those bearings to be concerned with. If that were mine I'd put them back in and run it. If the hose blew while you were standing there and the engine was shut down immediately there should be no damage to anything. The existing oil film will last long enough to protect in that case.

thank you for the reply and advice. as it turned out i took them to a speed shop the next morning, even before i saw your reply) and the 2 men who are supposed to be sharp told me that exact same statement. so i did just that.
I'm now knee deep into fitting it into the toy truck. got the drivers side ehaust complete with only one small dimple in the cadco header. 2 1/2" 304 tubing all the way with flow master 70.

thought i was in great shape, then i started fitting the passenger side header, WOW what a nightmare. had to flatten the #3 and 5 tube a bit as well as notch out a bit of frame.
my plan is to add a section of 3/8 wall to the remains frame to make up for the loss of strength. good thing i have a tig rig in the shop, huh?
has anyone else had issues fitting headers to these big block caddies?

External oil line isnt the fix. Fabricate a .875 i.d. pickup tube with free flowing screen section. Need more oil in to get more oil out.

Big Cadoo, do you have any flow data on the .875 id tubing in relation to the stock pickup? I've been pondering a move to a larger pickup tube on my new build.

Flow Data. Like in a testing laboratory? I posted the modifications I made to Cad500 to eliminate a problem. It worked for me. I dont extrapolate data or bench race. I see a problem, I evaluate and then I physicaly address that problem to remove it. Look at my postings and see what worked for me. You can do what you decide on. Dont ponder too long with an oiling problem.
