6 MM Stud Conversion Kit for Oil Pumps, 3036-10
6 MM Stud Conversion Kit for Oil Pumps, 3036-10
Price: $6.95

6 MM Stud Conversion Kit for Oil Pumps, 3036-10 helps you install the 8mm stud oil pumps into your 6mm studded case that you are using. Using this kit prevents leaks and problems, and is needed because new 6mm stud pumps are no longer available! ACN recommends that you use a 21mm pump in any single relief case application.

The stud spacing on the 6mm studded cases is slightly different than the 8mm version. If they were the same you could just drill and tap the holes to 8mm, and use an 8mm studded pump, and bolt it together. But it's not that simple. That's also why you cannot simply use a "step stud" with a 6mm case end, and 8mm pump end. So this kit includes 4 long studs, nuts, and washers. You put the studs in, and thread them so they protrude in the case enough to get the nuts on the inside. Use loctite, and tighten the nuts against the case, with no stud sticking further than the top of the nut. Now the pump nuts on the outside can be tightened without the risk of the stud stripping the case threads, since it's backed by a steel nut on the inside!

Bugpack Oil Pressure Boost Kit, 1970 & Later (Dual Relief Cases), 3041
Bugpack Oil Pressure Boost Kit, 1970 & Later (Dual Relief Cases)
Price: $7.95

Bugpack Oil Pressure Boost Kit, 1970 & Later (Dual Relief Cases), 3041 do NOT do what most folks think they do. These raise the max pressure at which oil is bypassed back to the sump, and it routes more oil through the oil cooler sooner. It will raise the maximum oil pressure that the engine exhibits. If you have a low oil pressure problem, you need to make sure the relief piston tops are FLAT (they are often not flat at all), and take a peak at the piston seating surface in the case, they are often not flat either, and either of these situations will bleed off vital oil pressure. The other thing to check is your oil pump gear clearances, and end play clearance. Blueprinting the oil pump followng the methods shown in http://vwparts.aircooled.net/How-to-Hotrod-Your-VW-Engine-by-Jeff-Fischer-p/how-to-hotrod.htm will maximize oil pressure at idle.
