year of case?

how do I work out the year of my case as its not the original one,my bug is a 71.
any info please
ROB

You probally wont be able to work out the year just the engine size.... whats the engine number and prefix ???

hey vw54 the only reason is that I'm going to put a full flow pump and they come for 66-70 or71-79.now my case# is AD 327285 if thats any help

I'm doing up an order from this mob and I want a spin-on oil filter pump but there are a few.http://store.cip1.com/Merchant2/merchant.mv?

You need to know if its a 3 stud cam, or a 4 stud deep dish cam, these are on the later engines

According to info. at Type2.com, an AD case is a 1600 replacement:
"(Never supplied in new cars -- only sold over the counter. All are
dual-relief with 10mm oil passages)."

no year was given.

thanks modulus,hey Dave Becker how do I find that out about 3 or 4 stud,are they the 4bolts/nuts that I can see on the oil pump plate?

FORGOT TO ASK...MODULUS is that a good thing or a bad thin about the case?

Short answer: Good.

Longer answer: VW had a single, 2-function pressure relief valve which controlled both direction and pressure; they later split this into 2 valves each with one function, thus the "dual oil pressure relief" case. This was not so important, the old relief valve worked fine; however, *at the same time* they increased the case oil passages to 10 mm (from, I dunno, something smaller...) to allow more oil flow to the heads; this is the good bit. Most hi-po Type I engine builders use "dual relief" cases for this reason.

The only way to be sure if it is a 3 or 4 bolt cam is to pull the oil pump and have a look. You cant be sure that it hasnt been rebuilt.
You are going to have to pull the pump for the new one anyway, so......

With the case as well it "should" be a 8mm stud case saved as opposed to 10mm not saved?
This is also a desirable factor. The 10mm studs grew move and pulled out of the none saved case holes

ok but when I got the motor rebuilt,the guy said he had to put a new/another case in cause the old one was stuff.it cost me $200 and he said it had case savers...me at that stage said "yeah what ever".but this good right??
ROB

yep

case savers are good

A case with savers and 10mm studs though makes a bad contender for boring for bigger cylinders. 8mm and savers is the choice. 10mm and no savers is last choice

hopefully this will guide you to the year make. it is accurate for me.
