A little grease on the retainers helps them "hold" onto the valve stem. Just a old school thing. :thumb:
 
You're nailing this build. Subscribing. I love your attention to detail- you've done your research.
Right on man thank you I really appreciate it! Yeah I spend a lot of time going back and forth between manuals, threads, forums. I just want to make sure I get it right and minimize variables when troubleshooting down the line
 
I agree with everything except packing the oil pump. If it sits too long, any grease will "set up", for lack of terminology. I use the same assembly lube, even on the internals of the pump. My experience was with a Saturn 4 cylinder motor from a parts store. It was packed with grease (not petroleum jelly, so you are fine) and that shit set up hard and the engine never got good oil pressure. I figure that rebuilt motor had been on the shelf for a while since the "lube" got hard.
Otherwise, nice pics and tutorial for beginners! Adding the impact driver part is super important on those 7 bolt motors. 6 bolt oil pumps don't have that one stupid screw and it WILL STRIP OUT if you don't do like you said! :thumb:
We ended up rebuilding the original Saturn motor and it now has 80k on it and purrs like a kitten at 35mpg!

Thank you I really do appreciate the feedback! That is my intent with this thread is to take what I'm learning along the way and consolidate it in a nice, easy to follow package. Also a good opportunity to recieve feedback and extra tips to refine/improve the build and advice. It gives me better direction but also gives someone that finds themselves where I'm at a good starting point. I'm already at square 1 so may as well document it as best as I can haha.

Yeah I was apprehensive about using grease and felt better with the Vaseline. Seemed weird but it was general consensus across various builds/builders and makes sense with the way it sits at room temp in the jar itself.
 
The only thing about petroleum jelly is if it is in a warm environment, it will melt. The assembly lube doesn't. I took a motor built 12 years ago and robbed the roller rockers off of it and my (and yours) assembly lube was still where it was when I put it together. It had sit in my house temperature garage the whole time. Just differences but good for your thread! ;)
That 12 year old motor is just now sitting in the engine bay of my oldest son's 86 Z28. We will try firing 🔥 her up in the spring.
Keep up your documentation, it's a great thing to have here on the forum! :thumb:

Definitely good addition I appreciate it! Also great time tested documentation of the assembly lube, that is definitely great to see! Hopefully that motor fires right up for you guys that would be killer!
 
I don't want your readers/followers to think that I assemble my oil pumps dry, because I do not. Always assemble them with some kind of lube if you have them apart. You use petroleum jelly, I use break-in lube. Any lube is fine. You DO want something in it to help with oil pickup on initial start up or when you prime the engine, whichever is done, even if it is clean engine oil (it is thin, but will work too).
Just clarification. Good thread!

I definitely appreciate it. Can’t wait to get to the point of starting to assemble stuff. Love the way you are laying it out.
 
Oh first one well welcome, to the love or hate platform, i still love it, ive been breaking parts and fixing since, 94. I think im on number 6. Just take your time i need to redo some stuff once shes broken in and running too.

Oh I've been loving it so far and the people on the forum have been awesome! I just can't wait to finally drive it! I've always been chasing an evo and still am but I love having this car too. Plan to keep this and get an evo too. I can learn through building this now and use that down the line for the evo!
