Can I use vaseline in the oil pump to prime it? I removed it to change the rear main seal. Can I fill it with oil before re-installing it or will this be usless? I don't really want to remove the distributor. I'm afraid I will be one tooth off.

:thumbsup:surething, I just did my rear main a month ago and i forgot to fill it with vas . I did a dry start thinking it will pickup because pump is immersed in oil,wrong! 10 seconds no oil pressure, last resort as i was not concerned about bearings as they are stuffed anyway was to give it a big rev to 2,500 rpm then she picked up WHEE.:D Vas in pumps will always pick up:thumbsup:

Don't sweat the small stuff. Pull the distributor and prime the system with a drill. Remember the rear maim you pulled has no oil in it, retiming is well worth the hassle than taking a chance of burning a bearing...

I would never put Vaseline in side my engine.

I gotta' go with Ivan. Pulling the distributor is nothing compared to the chance of plugging something up with vaseline or starting with a dry bearing.

vaseline is a petroleum product. it will dissolve in oil. I would run in the engine and then change the oil. The last time i put in a new oil pump the instructions that came with the pump said to fill it with vaseline for what its worth.

Did you put some assembly lube or motor oil back on the RM bearing befor re-installing it?

Vaseline in an oil pump is common. No problems there.
HOWEVER, for the little trouble that its worth, I would still yank the distributor to "prime" the system. Vaseline only lubricates the oil pump...you will still starve your bottom end for a few seconds, and to me, that's not worth the gamble.
You CAN just turn the motor over with the starter to prime the system, but again, I would just yank the distributor real quick and use a drill to prime the system. Remember, you have NO oil in the pump/pickup, unlike when you change your oil. Also, did you remove the oil filter? That is another part that could be a potential problem! I always fill the oil filter FULL of oil before install....especially a new filter! Its a verticle oil filter and easy to do.

Is a new oil pump's warranty voided if it's opened and packed with Vas?

I'm with Ivan and Tim. When it's so easy to pull the distributor and prime the engine properly...you get so much more benefit from this anyway...why mess with the pump? With tight tolerances I wouldn't want anything as thick as Vas being pushed through the engine.
