There was a problem filtering reviews right now. Please try again later.
I saw the review about adding washers to the bottom the the main bushing to raise it up in order to build oil pressure. Not needed on my standard sized Big Block Chevrolet (BBC). I also looked at the reviews that said to grind/bevel the end of the tool to enable it to mate with the oil pump better. Again, not needed for my application.
I forgot about beveling the end of the tool until I had it about 3/4 the way into the engine to mate with the pump. 3 seconds later I had it mated with the pump. My pump is an aftermarket Mellings oil pump, so that may have something to do with it. I re-installed it multiple times, same result, worked great, easy install.
About the review that added the washers to make it work... No problems here. I have an aluminum Donovan block, Mellings oil pump, and a Corvette 1969 intake on my custom big block motor, and it was obvious within 5 seconds that it was building oil pressure in the motor, no modification required for the tool. The only thing I will note is that I had to run my Dewalt cordless drill in the 3rd speed to generate the pressure to get oil to flow through the "open" valves (my valve springs are about 700 pounds of force full open, about 3x a stock motor (all other valves flowed freely (I did not note the oil pressure on the gauge in the car, but from experience, more oil was flowing with the tool than the car does at running at idle (20 psi)))) (yup, that's a quadruple parenthetical...). With the highest speed of my cordless drill and the valve covers removed, the oil coming out of the valve train was flowing so fast, I had to damn it up at the back of the heads to prevent it from running down the sides of the block.
My $20,000 race car motor is not a stock application, but it uses a standard deck height, and standard size pump. The tool worked great! I would purchase it again for as well as it worked.
If you need to bevel the edges where it mates with the pump, then buy a dremmel to go with it, and be happy you bought two good tools. Worth every penny.
Happy racing
However, on my 1984 305 H.O. the lower slug on the tool's was exactly 5/8" lower on the priming tool shaft, compared to the actual distributor shaft. So, I had to modify it in order to raise the slug so it matched the distributor shaft (on an 84' engine).
I didn't have any washers that would fit the shaft and still give the sidewall clearance needed. So, what I did was took the snap rings off the tool shaft, removed the slug, and then measured 5/8" up the end of a 12pt 13mm socket. I then and cut the socket end down to 5/8" to use as a spacer under the slug to rise the slug up on the shaft to match the exact profile of the HEI distributor I'm using. Then, I used a little hose clip that fit the shaft, and put it right above the slug, in order to prevent the slug from riding up the shaft during use (there is originally a snap ring right above the slug, that holds it in to prevent it from riding up. But, since I moved the slug up 5/8" from IRS original position, the snap ring groove is now obscured behind the middle of the slug. If you had a lathe you could easily put another snap ring groove on the shaft in the new position, but I don't have a lathe... So, I just used a hose clip fixed to the shaft, in place of a snap ring. A hose clamp, zip ties, or really anything would work just the same above the slug, since there's no real pressure exerted up on it. It's really just there to assure the slug doesn't jump up while the shaft is running.)
Hope this helps someone out. Even with this, I'd definitely recommend this to anyone needing a good oil priming tool. It really is worth it.
The tool itself is pretty basic, but most importantly it contains the upper bushing that allows the oil to circulate throughout the engine as it would when the distributor is in place, rather than just spinning the oil pump and allowing the oil to pour back down into the oil pan without going through the bearing galleys, lifters and pushrods. Don't buy one without this upper bushing...
