Help me not screw this new motor up!
I get my new GM crate delivered tomorrow and I'm making a list of stuff I need to do/get while I have the motor out... anything I'm missing you guys can think of? Don't want to have a "Doh!" moment with something busted two weeks later.
manifold gaskets header gaskets fuel pump gasket fan gasket new motor mounts clean up fuel sender line pressure wash inside and general cleaning new radiator hoses fluids - oil, coolant, tranny And is it beneficial to take out the vacuum canister? Or does it do something good? There's no smog requirement on this truck anymore so I don't have to have it in.

Re: Help me not screw this new motor up!
One Thing That Ive Notice Is Be Sure To Check All Bolts Under Hood Like The Chassis Front End Etc. Years Af Use And No Maintenance Is A Bad Combination

Re: Help me not screw this new motor up!
You don't have plugs or wires belts. Also while I had it out I would rebuild my ditribitor with a new moduel and pick-up coil plus cap and rotor.

Re: Help me not screw this new motor up!
I've got a new distributor with cap and coil, so I'm ok there... I thought it would come with new belts, since it's a crate long block - no?

I would also get a new fuel pump and fuel filter while you're at it. The pump is only about 15 bucks new. |

Plug the dipstick hole you do not use if yours came with a right or left choice.

Re: Help me not screw this new motor up!
Cool!
I bought a new fuel pump, thermostat, belts, and a new air filler neck today. I also cleaned all the rest of the parts - bolts, pieces, whatever else will go on the new motor. De-gunked the intake manifold and the gak on the starter and alternator. Those were both newish too but the motor was leaking so badly they look like they have been on there forever. Also got a special break-in oil ordered today that has zinc added, and some other goodies. I guess it's technically considered racing oil, but prevents damage to the flat tappets. The creaky old guy at the auto store recommended it, and I figured, ok... better than the walmart oil.

Re: Help me not screw this new motor up!
About the oil you use I use rotella 15/40. The reason is I have the flat tappets. The rotella still has the good stuff in it. Most of the other oils have been reformulated for the newer roller moters. We have been useing at work in everything cars trucks semis you name it. There is one car that won't die. It's a 96 grand prix, has over 300,000 on it and still runs very well.

I just want to know what to use from now on... the whole reason I have to replce the motor is a blown cam plus some other yuck. If I can use regular oil with an additive, great - if I should be using something special, I will. I appreciate y'alls advice - I have gotten TONS of great info here I could never get searching online...

Re: Help me not screw this new motor up!
don't forget to plug the one bolt hole in the lower right side of the engine that has passage into the fuel pump rod cavity. if you don't it COULD leak oil badly. A lot of seasoned guys still miss that. I always use it for the battery ground with a 3/8-16x3/4" long bolt so i know something is in it. crossy
BTW- what's a fan gasket. Is it next to the muffler bearings?? :-)

Re: Help me not screw this new motor up!
The single most important thing is to preoil the heck out of the engine and to take a little time to ensure all the seals are wet. The second most important thing is to do a proper cam break-in. Finally, run top-quality dino oil (Rotella is a good choice) and a pint of GM EOS and change the oil and filter after break in, after 100 miles and at 500 miles where you can consider the engine fully broken in.

Re: Help me not screw this new motor up!
Ok, that's two votes for Rotella oil plus another few agreements from out in the field. Sounds like that is a good one to use. I picked up my case of oil today from the auto shop, but it's nice to know I can get something that doesn't cost $5.50 per quart.

We got all the peripherals we could (fuel pump, upper motor mounts, manifold, custom egr block, balancer) on the on the block, then dropped the motor in. It wasn't as bad as it could have been, although a pivot point on the chain hoist would have been nice. We ended up leveling out the engine with a jack underneath, then shoving it into place onto the lower mounts. The tranny is bolted up, and one side of the headers are in, but we are having a hell of a time trying to get the driver side headers in. The #1 exhaust pipe has a 120 degree bend that's making it nearly impossible to thread on, much less bolt to the block. We stopped for the night rather than risk busting up the threads. Oh, yeah, it's just to the right of the wiper fluid dipstick. (doh. meant water pump, thinking behind fan...yeah...)
