Mexican oil pump worth it or leave it alone?

[wcfvw69]

I think a filter will add life to the bottom end of the engine, no doubt. But, there have been many owners of VW's without filters who put 100's of thousands of miles on their VW's and achieved 150k miles before tearing it down for a rebuild. I remember all of them changed their oil like every 1500 miles. Of course, oil was cheaper back then as well.

When I tore my 67 bug engine down to rebuild it, the bottom sump area of the case was covered in a fine grit material that felt like fine sand. Maybe it was a piece of the fuel pump stand that was grinded up? When I saw that I knew the bearings were going to be in terrible condition from it. None of the main bearings or rod bearing had any damage or wear from that material. It appeared to have just been sitting at the bottom and was not circulating.

I've thought about adding filters to my stock engines in my bugs but then remembered that I don't put more than a couple of thousand miles a year on them. I change the oil annually and figure the engines will out live me by a long shot.

If It was the 70's or 80's and I was daily driving my bug or bus, I'd absolutely add an oil filter.

Zundfolge, where did you get your OEM Mexican pump?

In truth that filter is only on there to keep out dirt and debris while it’s sitting. I was impressed with fit and finish on the OEM VW part.

Here’s more pics of Mexican pump installed. I probably had to back the studs out just a bit other than that it mounts up easy. Oh God there’s a Toyota filter.

No cutting or trimming to fit. It clears the tin and the pulley.

From the Mexican thread:
OEM Mexico set up used longer case studs with nuts. just FYI for anyone interested
this is of hopkin's Mexican Beetle filter

Studs do not work so well, getting standard 8mm (13mm head) nuts to fit on the left side is tight, socket does not fit, tried it, the 11mm or 12mm style nuts might work then if the stud on the right side is a little long the tin will need relieved. Probably why CB started shipping the pumps with allen heads.

Allen bolts.

I can confirm that at least within the past few years the CB Maxi2 comes with the allen head bolts pictured and not longer studs.

Mr C., now I'm confused. From your resurrection thread the pictures and discussion seem to suggest the CB pump came with allen head bolts? Did it actually come with studs and you just used those allen heads instead?

I'm also strongly considering getting a spin-on filter pump combo(either OEM Mexican or CB Performance), as I have a muffler with the heat riser on the passenger side- so I don't have clearance issues to deal with

[I'm aware CB requires 'adjustment' of the pump fins to clear the pulley tin.]

Anybody know if the OEM Mexican oil pump uses the stock studs in the case to bolt to or does it require removal of the studs and use bolts directly into the case- i.e. like the CB Maxi2?

Does the OEM Mexican pump also have pulley tin clearance issues?

(if this is a thread hijack or better suited for another thread let me know)

one of the reasons i was really paranoid of flying was seeing the "repairs" performed by my aviation mechanic customers on their own cars...
