That is the best tool available. It is one piece and no chance of anything falling into the pan, causing undo time and labor, to retrieve. The only real reason for pre-priming the beast, is to make sure all components are oiling and pressure is built up to the required spec's, with no leaks etc. This also pre primes the hydraulic lifters if used. Other than that, a good engine builder will have used some type of assy. lube on the bearings, cam lobes, lifters, etc. A mix of oil and Lucas treatment, or even better, a tube of brand name assy lube grease. You can spin that engine over for quite a awhile and without worry of engine damage, if all components are assembled with correct clearances and such. Also the oil filter should be filled with oil before installing, to lessen the time it takes for the pump to fill it on crank up. This should be done on normal oil changes in any car you own. Some filters are at unusual angles, so this can be a bit messy, but worth it in my book. By the way, use a good drill motor when using the priming tool, especially if you have a high volume or high pressure oil pump, those el cheapo models will lug down and burn up, if your not careful. You will find out just how much energy is required to spin that pump in your favorite engine combination.
not for nuthin... what i do is.... take out (and mark) plugs. remove the coil wire. crank engine until oil light goes out. of course, don't run the starter for more than about about ten seconds at a time so you don't wreck the starter.
The idea of priming the motor is to get oil moving around BEFORE you turn it iover with the starter. I agree with Old Guy though. My new motor was assembled with enough lube that it wasn't needed. But, I did it anyway. I like insurance..
i wouldnt recommend the magnetic ones put together.....they could get stuck in there or maybe fall into the pan...not sure if that could happen.... but i used one like it....only difference....get one that is about 8 inches long.. or go to autozone or checker. you can rent one...or buy one....and they are like 8 bucks i think.... all i did was rent one... make sure your valve covers are on first.....or you get a nice mess all over your headers.... and good idea to have someone watch the oil pressure gauge....make sure you get over 30 psi... if not....crank bearings could be wrong.. this happened to me,... i was given the wrong bearings and i never plastigauged.... leasson learned...
