How are the lifters oiled on a slant six? I don't see any oiling holes in the lifter bores. Am I blind? am I not looking in the right place? I admit, I haven't looked CLOSE yet like with a mirror or magnifying glass. Thank you drive through.
 
I haven't looked inside a sl/6 for like 25 yrs or more, but I do remember that the oil pump bolts into the side of the block, midway along the block down low on the Rt side. It's driven off the gear teeth cut into the middle of the cam, and the oil pump mounting face has ports cast into it to mate with ports on the side of the block. Now on the earlier, pre-1980(?) mechanical lifter slants, there may not be a lifter oiling gallery. It might just be splash/drip lubrication.
For the hydraulic lifter slants, they must have an oil gallery, but I can't say I've ever seen one taken apart, so I can't say what it looks like, or specifically where to look.
 
Solid lifter slants, have splash oiling on the lifter base, and just, for lack of a better word, drip oiling of the lifter bore.
Hydraulic lifter slants, have the lifters lubed, through hollow pushrods, rocker arms, and rocker shaft.
A FYI: the rocker arms, rocker shaft, push rods, and lifters are different between the two versions. As, of course, is the cam.

Ok, so on the hydraulic slants, the lifters oil "backwards" from top through the pushrods and into the lifters, correct? Then I need hollow ball and cup pushrods. That's what I thought I was lookin at at the oiling diagram for the slant. Thank you.

No, the solid (adj) rocker arms will not allow oil to the pushrods. You need the hydraulic rocker arms, and shaft. The oil holes in the hydro shaft are located in a different position, then in the solid shaft.
 
My plan is to run a solid roller camshaft so I don't see how a hydraulic setup will help me. Connect the dots for me. What I had planned on was running hollow adjusters and pushrods on the solid rockers I have. That way the lifters would get oil, would they not?
 
I never looked into running solid rollers on a slant, so I have no personal experience, here. Why not just run the stock type solid adjustable rockers and pushrods? I wouldn't think you need to get additional oil to the lifters, then the splash oiling. Look at what they do on small blocks when using rollers, they install a tube in the main oil gallery, which blocks off oil to the lifters. There are a couple of oiling mods some slanters do for additional cam lobe and lifter oiling. They cut a small vertical groove, down the lifter bore, and install "standoffs" in the drain holes in the lifter galley. There were pictures of these mods on slant six dot org, but photobucket screwed that up.

There is no oil gallery to or through the lifter bores on any slanty, there is only drain-back oiling and the oil running out of the pushrod cups and down the side of said pushrods to the lifters on mech valvetrain, holes up the middle won't really help since the adjuster balls aren't hollow. I doubt much will get thru there.

I plan to run hollow adjusters.
 
OK, still runnin' with those Buick rockers?

I'm not sure. It will be one or the other. The Buick rockers are going to require a LOT of labor intensive drilling. I have a lot of time, though.
 
Did you retire? What's o'Reilly gonna do without you?

Yeah, it was kinda a dirty deal. It was going to get ugly for me if I didn't back away so I did. I was planning on finishing out the year and then calling it done, but I am glad it happened now, because my feet are so much better. My hard headed butt would have kept pushing until I had to have surgery probably.

Well, congrats! I hope everything works out for you!
I worked auto parts counters many years ago.
I can retire from the IBEW in 3 years and I think I'm gonna work part time at autozone when I do. So I'm kinda doing the opposite of you.

Thank you. It will! I just kinda hated it because this was the first job I ever really loved. It's ok though. I am having a good time bumming around the house.

I here ya pal! My best times are when my company has nothing for me to do and I have to take off a few days. The guys I work with crack up because they know I've got retirement figured to the day: 3 years, 2 months, and 19 days to be exact!
 
Just think about all the time you have now to work on your car stuff !
 
Rusty do you think that the 170 will serve you better for your driving than the 225 would, everything else being the same?

Possibly. That's why I am not ruling out selling the 225 when it is completed. This early in the game anything is possible.
 
Not trying to hijack the thread, just a FYI.
My 64 Valiant more door, has a 170, 3 speed on the columm, and a 7 1/4 rear with 3.23 gears. gets upper 20 mpg. Engine is not stock.
 
All honestly I never could tell (power wise) any difference in a stock 170,198,225. They all ran about the same to me.
