Question:
Do you need to pack the gears of a new ungraded oil pump with Vaseline IF you are going to spin the pump through the distributor hole before engine startup?.
I'm fitting an oil pump upgrade kit as well as new cam chain and gears.
The Vaseline will dissolve into the oil, it won't do any harm.
I would make sure the pump isn't dry before spinning it up though, just coat the innards in oil when assembling it, as a dry pump will take longer to prime.
Thinking back to the 2000/2200, and how high their oil pump was, I dont ever recall having a priming issue after an oil change.....Isnt there a weir of some sort holding a pool of oil up inside the pump?
