Re: Oil cooler seal Poll

["Jim Adney" <jadney@vwtype3.org>]

Okay, I made some more measurements of oil cooler seals and related 
parts.

spacer washers, only found one set which appeared to be thinner than 
I remembered: 2.5mm.

8/8 seals: 6.5mm
10/10 seals: 3.7mm
10/8 seals: 3.7mm

cooler offset: ~2mm

This gives the following clearances:

A cooler mounted with spacer washers has 4.5mm of room for an early 
6.5mm seal, leaving 2mm of crush. If the late seal were used here it 
would be 1mm shy of touching, let alone sealing.

A cooler mounted without spacer washers has 2mm of room for a late 
3.7mm seal, leaving 1.7mm of crush. Same for the adapter seal.

I would be tempted to put a 0.5-0.8mm spacer in this latter case to 
reduce the crush, but I have never done so. My late engines have 
always assembled nicely with no spacers.
