Description

This is a oil priming tool for GM Gen III and IV car and truck V8 LS1 style engines. It will work on late model '99 and up GM Silverado and Sierra trucks, as well as "97 and up Corvettes, and also including '98 and up Camaros. Now currently available for Ford 1999-2012 modular V8 Mustangs and Trucks.  It will also work for Mopar distrubutorless ignitions with the addition of optional fittings. 

The oil galleries of newly assembled LS will be dry of oil. All engines should ideally be "prelubed" before starting for the first time, which incidentally is where most of the engine wear occurs. Unfortunatley, the design of the LS oil pump does not allow an easy way to do this. Since the oil pumps on Gen III and IV engines drive of the crank snout, the oil pump can't turn seperately from the rest of the engine. Therefore, it is not possible to use a drill operated tool on the the distributer gear of older GM V8s. This tool solves that problem. With MDR Tuning's Engine Oil Primer, everything you need is included to easily prelube and prime the oil system of your newly built engine, or even a vehicle that has been sitting for an extended period of time.

  • Required to prime engines with crank driven oil pumps
  • Prime your engine through the oil pressure sending unit port (Hemi, Coyote, Ford Modular)
  • Perfect for modular engines that have crank driven oil pumps
  • Prevents engine damage caused by only using starter motor to prime oiling system   

Dont let this happen to your engine!

                  OIL STARVATION

Appearance: Bearing surface streaked and smeared with worst damage at center. Heat discoloration. May show pick-up of bearing material on shaft depending on severity. NOTE: This condition will progress into “Wiping” and “Hot Short”.
Causes: Low oil level, blocked oil pick-up, oil pump failure, blocked oil hole or oil passage, excessive dilution of oil by fuel or coolant, lubrication system not primed before start-up, overspeed. 

                               WIPED

Appearance: Bearing surface smeared or scratched and torn. Bearing metal melted and re-solidified along the edges.
Causes: Lubrication system not primed before start-up. Clogged oil passage. Oil pump failure. Improper installation (oil hole blocked). Concentrated loading in localized area of bearing. Misalignment of shaft and bearing surfaces. Insufficient clearance.

Dont forget to add a Break-In oil Kit to your order for the best

After doing a bunch of research on how to prime a LS engine, I can’t believe the amount of bad advice that was out there. There was no way I was going to chance cranking my new engine without priming it first. So I was happy to find this product, cheap insurance. I chose the X Prime HP model. It worked great and when I fired up the engine, instant oil pressure, no dry tapping lifters, no staring at the oil pressure gauge hoping for it to move. I definitely recommend this product.

Many of us have invested significant amounts of time, energy, and money in our LS Engine transplants / rebuilds. After laying dormant for ~2 years, I was concerned about starting my engine dry. I researched the official GM tool, the Car Craft pre-luber, over-filling the crankcase, jacking up the rear of the car, the grease gun method, various hand pumps, and cranking with the starter with the plugs removed. After pre-filling my filter, removing the plugs, and bumping the engine with my starter – I got 0 oil pressure on my new OTP mechanical oil pressure gauge. Concerned about my investment and resisting the urge to just start it and hope for the best, I got serious. Further research led me to MDR tuning’s X Prime LS engine pre-luber.This kit is elegant and simple - with several options. A simple electric pump and hoses with the appropriate adapter fittings allowed me to remove my driver side front oil galley plug (GTO alternator removed), hook the kit up to the pump / 12V battery, and push 2 quarts of oil through the engine in about 30 minutes with the standard pump. Oil pressure showed ~5 psi with my engine / oil viscosity combo. It’s probably overkill, but I also rotated the crank a couple of times as the oil was being pumped into the engine. After re-installing the alternator, I was rewarded with 45 psi oil pressure during first crank / start-up and no lifter rattle. With all of the time and money I put into my project – it just seemed like money well spent (about;$100).This isn’t any paid advertisement – I paid for my kit like anyone else. Just wanted to thank Mike for putting together a nice kit, with several options, priced right.
