yeah... I hear ya on that. Although, if you get yourself a simple push button switch and rig it between the starter and the battery and disconnect your ignition its super easy to bump the motor around as needed vs. turning the motor manually. I just hate leaning over the engine bay for the time it takes to adjust these puppies.

CamaroCorey :
I couldn't really tell much from the videos. Sounds like you got enough advice but for the sake of pitching in, I would lean more towards starting from scratch on the adjustments everytime. Simply since you cant really know how much something has possibly loosened compared to the rest and this way you get them all to the exact same setting. I was encouraged to set it to 1/8 turn past zero from a trusted mechanic. I agree with someone that said above though, its a little tough gauging 1/8 turn. hehe...

You guys suck... now that I'm thinking about all this I think mine need to be rechecked. grrr...

Thats how mine sounds...None of my rockers are loose at all so its probaly not enough preload just my guess.

Does anyone adjust theirs when the motor is running? Ever since I got my new valve train it's been pretty loud..I've gone back in and readjusted them 0 lash then 1/2 turn. Its only the driver side too... sorry to hijack, just quick question and i'm done! haha.

I've never done it running. I get flashbacks of a buddy's experience getting oil everywhere and lighting a rag on fire from it touching the exhaust. hahaha... funny now but yeah, not so funny when it happened.

Haha, I can understand that.

Yes I've done it that way a couple times but I prefer not to just because of all the oil squirting everywhere.

I decided to do it with the motor running, it is alot quieter now you can hear the ones that are making alot of noise that way. Figured I'd give it a shot.

I've been doing them "running" since the 70s. Yeah the oil can get messy, but I used to have a set of valve covers with the tops cut off, to try and control it. However, that wasn't within the "spacious confines of a 4th gen's engine compartment". But, the good thein, is that an LT-1 with the stock oil pump doesn't squirt as much oil out the pushrods as the old SBCs and Pontiacs I used to own.

how much preload did you put on them? Curious because I need to quiet these Pro-Mags down.

I ended up just going back and re adjusting them to spec. I've been told 1/8th turn is all you want?.. I think I ended giving too much preload when it was running I just tightened what sounded like it was making sound, so different amount to different ones. I don't think pro mags will ever be silent. I'm going to completely gut out the valve covers too, cuz even with that side cut I think I'm still hitting somewhere. Hopefully that'll help some.. Good luck, sorry I wasn't much help!

Yeah Lloyd told me 1/8"-1/4" so thats what I did but its just so damn loud and I had different 1.6RR's on there before that were nothing compared to these.

Yeah, I've been told to get some lt4 valve covers to try to quiet the noise down.. Other than that, I think I'm just going to have to get used to the extra noise...just gonna have to run the open cutout more often I suppose. if you get them quiet and the valves are still opening and closing properly let me know! haha.

Same here I picked up some thick aluminum covers to keep the noise in but haven't installed them yet because I have to cut and splice some new plug wires but hopefully they will work. If I get it figured out I'll definetly let you know.
