Replacing the original 24mm oil pump with our larger 30mm high volume oil pump provides two main benefits:

First, it helps solve the notoriously-low oil pressure issue that is typical of the waterboxer engine design and the accompanying low oil pressure warning buzzer issue. If you've read our article on the subject—you know that our high-volume pump kit can help quiet that buzzer for good! We include this larger-volume oil pump on every rebuilt GoWesty engine. Second, it solves the common oil leak issue between the oil pump cover and oil pump. We achieve this by procuring the absolute best quality pump available, machining the pump housing to accept an O-ring, and capping it off with our custom Super Seal Oil Pump Cover. No more wish-I-could-get-this-silly-paper-gasket-to-stop-leaking gasket!

Fits: All 1983-91 Vanagon Waterboxer

Features:
• 30mm high-volume pump with pre-checked pump gear & shaft*
• GoWesty O-ring modification**
• Custom GoWesty Super Seal Pump Cover
• Bolts, O-rings and sealing crush washers to replace the leak-prone stud/sealing nut combination

*We have found over the years (the hard way) that the press-fit between the driven pump gear and the shaft that drives it can vary to the point where the gear can literally spin on the shaft causing all sorts of hard to diagnose oil pressure issues, and even engine seizure. So, we developed a special tool to test each and every driven gear/shaft fit by applying a torque to the gear. We have flunked as many as 50% on some of the brands we have sold in the past because the gear press fit does not pass our test. This test adds very little to the price we charge for our pumps, but the value to you can be enormous. We are always striving to find the best pump on the market, and if we ever find one with gears that check out good 100% of the time: We can finally stop checking them! Yeah, GoWesty has your back.

**Between the pump body and cover we have added an O-ring to replace the gasket. We do not install additional O-rings between the pump body and engine block bore (the “triple o-ring” idea) because all they do is plumb the pressure side of the pump to the suction side and which actually reduces the pump efficiency.

Pro tip: On our rebuilds, we don’t use any of the gaskets that come in the box with the pump. Between the engine block and pump housing we use sealing compound.

Note: Installation instructions are not included. This kit is intended for professional installation only. Please refer to your Bentley Repair Manual for the proper procedure. Oil Pump Puller tool (VW201) required for removal and installation.

To small diameter

It is a loos fit in WBX crankcase.
Oil pressure will bleed off in crankcase, loss off pressure waist off money

Ho Koen, we are sorry this oil pump is not working for you. It has the same exterior dimensions as the original pump, so it should fit identically to the old pump you removed from your engine. If you would like to return or exchange it, please let us know. All the best, GoWesty

Finally fixed my oil leak

This finally fixed my vans oil leak. The first time around I only replaced the paper gasket on the original oil pump, this lasted a little while before it began leaking again. I decided to replace my original oil pump with this one since it does away with the paper gasket and used the O-ring instead. So far I have had no new oil leaks from this one.

Installing this is a chore but it is doable with the motor still in the van, you will have to remove the exhaust and engine mount while supporting the engine to gain access. I would also recommend buying a oil pump puller tool if you are planning to do this job yourself.

Installation cost

Just had this installed on my '86 Westy with 80k on rebuilt stock engine. So far, no more oil buzzer! Beware, though: professional installation was $950!
