Good work Phil. Torque on those valve cover bolts is a measly 106 in lb or a bit over 8 ft lbs.
yeah...... about that. I hand tightened, used the house dewalt impact drill until it didn't move the bolts, then I used a wrench and tightened them maybe another quarter turn. They are snug, but nothing crazy at all. I was real careful with the impact drill as I didn't want to snap a bolt or crack the cover. That aluminum seemed cheap so I didn't want it too tight.

You’re actually lucky you didn’t break the bolts even with that impact even if it’s a cheap 1/4” one. They’re super long and skinny as you saw and they twist right off. I should have mentioned that before. 8 ft lbs isn’t any more than barely snug.

Well after trying to figure out my brake issue the front hub started making little noise today. Guess that could be the issue. Bought the moog hub and it lasted just over a year :confused:

Whats the better one thatll last more then a year atleast. delco, dorman or timkin?
I’ve put Timken SP500301 hubs on both of mine.
Same advice as last time, Timken, they were the OE supplier at one time, or still are.
Seems like everyone swears by timken here. @07Burb, recommendation? Didn't you replace your red one with timken?

Should I loosen them a bit or just let it go?

Just buy a set, the ones I got were about $12-15 for 2 pairs that were slightly different from each other. They don’t loan them afaik.

Maybe I'll find someone to borrow them from, I just want to take the spacers out and drop the rear another inch. No need to buy them just to use them once

take the moog back to wherever you bought it, should have a 3 year warranty

You might want to loosen them so they don’t seize later. Just snug them up with a 3/8” ratchet.

Sorry, I was thinking about a different type of spring clamp so disregard what I said about those being so cheap lol.

Engine is out of the hoe!
mounted it up on the engine stand, didn't have bolts that fit so i made some spacers out of tubing and used the power steering/alt mount ones.
yup, to0 long to turn the engine.
:Big Laugh:

i'll get some bolts during the week some time that actually fit.

And i pulled the lifters outta there, noticed some light grooves in the rollers, it catches my finger nail just slightly.
I think i'm replacing them...

I borrowed a set from O'Reilly and they started bending. Borrowed a similar set from AutoZone and used all four to distribute the load. It worked fine, but took twice as long setting up and having to turn four compressors a little at a time. It's a cramped mess of steel everywhere.

You don't need compressors to remove spacers in the rear. Unbolt the bottoms of the shocks, unbolt the bottoms of the sway bar end links, jack up the frame on one side until the coil is loose, remove spacer, lower that side making sure coil is seated properly, jack up and repeat for the other side, reattach end links and shock. Done. Just gotta watch the brake hose in the middle when jacking up the frame/body so you don't go too high. You shouldn't have to go very high with lowering springs, though.

Yeah I got confused on another thread where the convo was about my favorite kind of clamp (spring) for hoses and the pliers used to install and remove those. The last set of spring compressors I borrowed from an auto parts store almost killed me, years ago. My NNBS Silvy doesn’t have these contraptions yo. :cool:
