So far it seems I'll need the following parts (let me know if I am missing anything);
Fan Shroud VWP# 113-119-025
35mm Fan VWP# 113-119-031
Doghouse cooler VWP# 113-117-021
Doghouse mount VWP# 113-117-301
Upper Duct VWP# 113-119-431
Lower Duct VWP# 113-119-419
Cooler Seal Kit VWP# 111-198-029
Hoover Bit VWP# 113-117-323
Yeah, I feel like I just can't ignore Zen and The Godfather's advice. Also, this web site seems to back up what they said:http://www.vw-resource.com/oil_cooler.html
I'll definitely order the cooler ($40), mount ($20). upper duct ($10), lower duct ($10) and a seal kit ($3) from California Import Parts http://www2.cip1.com/
on Sunday. That way I can get in on their 20% off sale that ends on the 30th. I just might try to pick up a doghouse fan and fan shroud at a show or swap meet since we've got a few more festivals left this summer.
The hoover bit seems harder to come by. I can't seem to find a parts house online that carries them. Though, I've seen a few hoover bits on the Samba for around $20. That seems pricey though. Worst case scenario I guess I could cut one out of some metal flashing with some tin snips using this guys sketch:http://www.type2.com/rvanness/sealfram.htm
This seems like a lot of extra effort and bread but if it buys a little more life and dependability out of the engine I guess it's worth it.
