hard or soft copper line for a valley oil gallery bypass line?

What ever. I’m saying there is no reason to do the crossover if you think it’s going to save bearings.

I pulled out the other book and looked through it. The only thing that I see that he says differently is to block the oil feed from the cam by clocking the cam bearings to block the feed holes.

That’s a great idea but I wouldn’t pick up the oil to feed the rockers from the main oil feed down the passenger side. I have been looking at doing that on my junk especially when I do the W2 engine. But I would get the oil to feed the rockers from the feed to the oil pressure gauge. Then it doesn’t come off the main feed but I haven’t had a chance to look at it close to see if it would work.

Saying that, my ***** about this whole thing is guys are doing a mod that doesn’t do a damn bit of good as far as bearing life is concerned.

I went back and read the OP. I asked him why he wanted to do the crossover. He said to slow the oil down so it is evident he is looking for bearing life. As I have said many times it doesn’t.

It’s one thing to do a modification if it serves a purpose. For the OP the crossover doesn’t do that.

As for the mod to not feed any rockers off a main feed I did that in 2000 or so. Each shaft was fed from a separate feed that didn’t come off the main feed and it helped a ton.

The engine I’m getting ready to do won’t get all the modifications I did back then but I want to at least stop feeding the rockers off the main oil feed.

The block is already tubed on the passenger side and the oil to the drivers side is blocked with a set screw.

That’s my *****. Guys doing the crossover for the wrong reasons.
Wow you sound just like yellow toes. Or yellow rose that is. He never had a good thing to say about the benefits of the cross over tube which was designed by Chrysler engineers.
Robert I use aluminum tubing or braided line.
