Ok... After a bit more research I see the oil cooler at the filter base has been somewhat of a reoccouring problem with any vw with a cooler. I must say I have (in the past) been rather unfamilier with the anemities of the 88and up vw's. My rabbits and bugs never bothered with that cooler. Does it actually need that??? If so.. What increases temp from my old GTI motors? Just a thought. MOST importantly, any good source for the coolers? I am reluctant to get a used one because I do want to keep this one for a while. Thanks for all help in advance!
