87 engine build

When putting in the cam and crank should engine assy lube be the only thing I needed or should is there something else. When putting in the pistons I lightly coated them and the walls with clean oil to help, was that a good idea?

I read that the rear main seal should also be heavely coated with rtv to ensure a good seal, thoughts on this?

My machinist said I need to seal the head bolts? Is that entail putting rtv on the treads and torque them down?

Is it safe to spin the crank once all pistons are in and set to ensure clearence and operation? It won't hurt the block will it?

Thanks for the help you guys, I am having a lot of fun doing this.

I have received most of my gaskets and am still waiting on the misses to allow me to purchase a few more parts. Cam, crank, pistons and timing chain are all on. It is much easier to put her back together while on an engine stand. I went with Fel-pro gaskets for everything so far, when I get the headers I will use what comes with them most likely.

Question tho, What should I RTV and what should I not RTV.

Thanks again for the help and support guys and gals.

Hey "cousin" Jack, just wanted to update everyone on the build, the pics are too big to upload even after i cut them down. They are all in a folder on facebook tho if anyone is interested.

I got the new oil pump gears yesterday and was looking at the different springs, The one I pulled from the "stock" unit matches the plain spring in figure A, however according to the measurements and the diagram I should be using the 40psi spring in figure B. Just your thoughts on this and if it is better to run stock 40psi or put it up to 60psi.

Also on that, if the last owner had the longer spring and not the shorter correct one wouldnt that push the oil pressure up anyway? Is there a drawback to running more pressure than stock? Thanks for the input.

Ok so the motor is back together, placed in the car everything hooked up, at least everything i think needs to be hooked up.

Here is the problem.....

Primed the engine so there wouldn't be a dry start, Everything is the same as it was except no AC or Heat. When I tried to turn it over for the first time it cranked and had "little puffs of air" coming from somewhere by the throttle body. Never did start up, didnt want to crank on something that might be broken or not getting what it needs to start. Any help is appreciated everyone.

also gonna try to post a video somewhere in case you want to watch and hear it.

I found my coolant leak.... where my coolant temp sensor screws into the intake, it is cracked straight through the sensor location hole on both sides. Looks like I will be getting a new intake manifold unless someone has an idea to fix a hairline crack in the manifold.

That's not good... maybe have it welded.... then rethreaded...

Yeah I thought about that, i just hate to rip it back off after i resealed the shit out of it. on another note.... It being a tiny leak i still tried to get her to turn over, I do need a new battery but not sure what to get, leaning towards a red top.

Also, when it does crank it sounds like there is to much compression, it will puff once and then the motor seems to bog down during cranking. Any ideas before i give in and take it to a shop?????

sounds like cam sensor timing is off, check out the procedure here...
