I’m looking to buy a oil pump primer tool and while shopping around online I noticed that the majority of BBC and only a few BBF tools had collars on the shaft. I guess this is to provide a better seal so more pressure can build thus getting oil into the valvetrain? I tried looking into why more BBC tools had the collar whereas the majority of 429/460 tools were just a straight shaft. The only thing that I came up with was something I read on a BBC forum that said….
“Is the tool you purchased just a small shaft that spins the pump ? If so you will never get oil to the rockers. You need a tool that has a collar to simulate the bottom of the distributor housing. The distributor housing actually seals up one of the lifter galleys.”
And
“You really should get the correct tool. Without it you will never get full oil pressure to the bearings etc. If you look down in the hole where the distributor goes while you are running the tool you have, you will see a massive gusher of oil ..... that is where all of the oil is going, right back into the pan instead of to the bearings etc”
I guess what I’m trying to ask in a very long winded way is….Should I get a tool with a collar? Is it necessary on a 429/460 or do the big fords not have the priming problem getting oil to the rockers/pushrods that the BBCs apparently do?
Can anyone reccomend a good brand/type?
