Hi all (again)

After getting the oil pan pan on and verifying the clearance on my modified dipstick tube (for 4-bolt splayed mains), I went ahead and started priming the motor.

I am using a Generic (OEM brand) SBC priming tool (with a sleeve) to prime my oil pump. the tool slides down the hole in the block and meets with the oil pump drive shaft, but it appears that the sleeve on the tool (the one that seals up the big opening to provide oil pressure to both sides of the motor) is bottoming out on the cam gear and not allowing the spline on the tool to fully seat on the notch on the oil pump drive shaft. When i run the drill on the tool, it keeps jumping out of the notch on the oil pump drive shaft (since its not fully seated in there).

Is it just the tool I am using? I noticed that most use the proform tool. I just want to confirm before I go buying another tool. Any ideas? Thanks in advance!

i had the same problem with it not fitting so i just took my factory oil pump driveshaft/coupler and put it in my cordless drill, worked perfect.

I bet you go through a few batteries on those cordless drills. I just primed my motor last week and had to spin it for 20+ minutes before the last rocker had oil. My uncle has a primer tool on a corded drill. I know he didn't buy it....pretty sure he made it from an old sbc distributor.

Are you talking about the bushing or the piece that is higher than the bushing?

the bushing...i know the piece higher than the bushing is meant for the hole on the intake where the dizzy goes, which we dont have on LT1s

The picture you show has a beveled bushing. Mine is just straight. Here is a pic of the tool I am using

I take it the bushing is fixed? Remove it if you can. It will work fine. I used a right angle drill. Depending on the size of the drill you may have to cut the shaft down in order for it all to fit under the cowl.

Mine looks like that and worked fine. If the bushing is removed, you won't get any pressure.

Yep. My mistake. It's the top piece that I removed because I had to make the shaft shorter for the drill I was using. Here's mine:

So, that's the cowl mod for the priming tool?

Problem solved! Turns out the spline at the bottom of the tool was just a tad wide and didn't fully slide into the notch on the oilp pump drive shaft. Ground it down a hair and works perfectly now!

Thanks for the help!
