Priming the motor

[michael.konor]

Check around some local car speed shops and even machine shops and see if you can borrow/rent one. That's how I found out about them in the first place.

Those are very cool and look to be exactly what I would need. However, I just don't want to pay 200 bucks for something that is (hopefully) a one time use.

bug sprayer does the exact same thing, its only $13 but required manual labor to pump it up, and it takes a few extra minutes.....

I used the 'bug sprayer' approach, but just turned the motor manually. It wasnt in the car yet

^^^ me too. I also primed it again in the car while slowly turning the crank. No plugs in it and obvioulsy it turns over much easier. First time I fired it up had oil pressure instantly. Primed it right before I stared it for break in.

tmcolegr included a nice piece in his build thread.

I used the exact same setup and worked real well. I actually bought two sprayers ($13 ea. at lowes and the filters were $4 ea. at Napa IIRC) and use the other one to fill the auto tranny on my BMW and the mustang.

Does anyone prime their motor after sitting all winter?

 

[Riptide]

I've not read of many people who bother. If it's been six months or less most people just seem to go start it right up and drive it. Mine has sat for 4 months without being started and AFAICT there haven't been any issues.

This should only be needed on a new build.

I figured as much, I never start it all winter. I had a friend tell me on the weekend that the lash adjuster or lifters will bleed down and that isn't good when restarting in the spring.

One trick I heard was in the spring to pull the fuse for the fuel pump and crank the engine for a few short intervals to get some oil flowing. Worked fine for me. I also hear of people just starting it without issue.

I don't see how this helps at all if there is no oil on some parts. It'll still cause damage/wear where there is no oil.

I believe the idea is that it's better to have it spin at a low "starting" rpm for a bit rather than have it jump straight up to 2k and have it idle down from there. Easier on the motor getting the oil started through at whatever rpm a starter would turn a motor at rather than startup and idle, I'd imagine.

This is my understanding, I could be completely wrong though.

So what if your new engine was built using assembly lube, then primed with two quarts of oil; then shipped.

If the engine has sat for a few months since its been assembled/primed, would you bother to prime it again or just start it up?

 

[recordbreaker5]

I personally wouldn't "take the chance" of turning over a new motor that hasn't been primed. I don't know if anyone has asked, but did the motor come to you from a builder as a long block? I couldn't imagine a builder/assembler not priming it prior to it leaving their door.

 

[cwhit23]

No , I have been building the motor with some help along the way. I had some experts come in and do stuff that was above me and I had a machine shop do all the typical machine stop stuff, cleaning the block, balancing, etc. But the block has assembly lube, but I just haven't primed it yet.

 

[crownaviation]

I won't let the car sit for more than a couple weeks without starting. Also have stiff springs for my comp cams. cwhit23 gonna leave now to go get those parts.. could not make it there this morning and finally done for the evening.. will email you some pics but need your email as our pms will not let me send you a pic for whatever reason..
