Hey guys, I have a quick question about where my heads get oil from. It’s a 69 Buick 430. I just installed a high volume oil pump and I’m getting 55ish psi from a drill but I had to loosen my rocker arms to get oil up top. My dad (waterboy) said my bolts were just too tight on the rocker arms because it oils from there. Just double checking on here. Really hoping I don’t have a bad cam bearing... Any help is appreciated! -Scott
The oil comes through the front pedestal, into the rocker bar then out the lifters. Tighten to around 25'lbs if I remember correctly
Sometimes the feed hole in the head gets filled with build up. If you remove the shaft and look right beside the first bolt hole you will see the feed passage , make sure it's clearly open
The heads were pulled off and completely redone by our local Buick shop, but I’ll be sure to look anyway. Valve covers are off so 4 bolts are not that hard
You can tap the end cap off the rocker bar and make sure its clean. Mine were completely filled with sludge.
Correct. just pressed on. I took a crescent wrench and adjusted it to where it just cleared the shaft resting on the cap. with the shaft clamped in a vice between 2 pieces of wood, smacked the wrench with a dead blow hammer several times until it popped off. Shaft was nearly full of hard sludge.
I didn’t know you could do that but I’ll have to give it a try. I cleaned out my oil pan and there was a ton of nasty sludge in it, so I’m sure there is sludge other places....
