Aren't the oil squirters on the connecting rods and caps supposed to face INward or toward the outside? I thought they were inward to throw oil against the camshaft.
The reason that I ask: A buddy with a 340 Dart is having a strange knock/rattle in the bottom end and I wonder if his engine builder made a mistake. It is a fresh build with very low miles, maybe less than 100. Oil pressure was 50 at cold idle. Oil is clean. He pulled the RH valve cover and watched the rocker arms and pushrods move at idle. No problems there. The flexplate is not cracked, the torque converter bolts are tight, the shield isn't hitting anything.
This noise is intermittent. It can start at idle or be silent. Once the engine is revved, the noise sort of "flares" then quiets down to about half as loud.
I tried to pull the oil pan but he didn't have a pickle fork for the steering linkage. I should be able to get the pan and windage tray off tomorrow to get a look at the rod caps. If any are loose, that is obviously trouble but I was curious about the oil squirters.
Thanks!
