Overlap Triangle

I will be dropping off my block off at the machine shop this week. Would you tube the block or bush the lifter bores if it were yours?

If you have the money you can bush them.

If not I just tube them and block the oil off to the drivers side with a plug

Yall smell that? I farted.

I’ll answer your question with a question……

Do you want your DLC bushing lifters to have pressure fed oiling to the bushings……. Or not?

I can honestly say I don't know. What method would be better?

If you need oil to the rollers or if you pushrod oil you can drill the bushings before you install them. a .060 hole is plenty big.

If you tube it, you can drill the tube after its installed and finished. I don't do the oil holes until I run the peening tool through the tube and make sure the lifter moves freely on the bore. Then I drill the holes. .060 is plenty bug enough for that too.

On the drivers side, I use a set screw with a .125 hole in it down at the main bearing. That is enough oil to feed the rollers and/or pushrod oiling.

I haven't done it yet but I will probably start tubing both sides. I can't see why not to do it. But if you just tube the passenger side and restrict the drivers side that's good too.

I did tube my last block. After the peening was done, I had to use a sandpaper roll to get the lifters to move freely within the lifter bores.

Now I did not drill any holes in the copper tubing in the lifter bores.

If you aren’t pushrod oiling or you don’t need to pressure feed the lifters I don’t drill any holes either.

Ok.

I am pretty green with this stuff and still learning.
