Hopefully that's not an omen on mine. I had a really good rebuild about
140,000 miles back, and has never given a lick of trouble in that
regard. However - you never know with Vanagons.
I got 205,000 miles on the original engine on my first Vanagon - an '85
GL with the 1.9L engine. The only coolant failure thing on it was a
water pump failure just over the 200,000 mile mark.
On my current '88 GL -it had an engine replacement somewhere between new
and 96,000 miles. I bought it with 86,000 on it and at 96,000 miles it
came apart. On teardown, a yellow tag saying Volkswagen of Canada
Manufactured Engine - so somebody abused the HE-Double Toothpicks out of
it before I got it. I'm very easy on engines, so it wasn't me that
brought it to the brink of destruction = But TWO new engine in
96,000 miles - WOW, Anyway, Jim Connell of Jim's VW in Leeds Alabama
built this engine I currently have and it's been a terrific performer.
Right at 150,000 and no major trouble so far. Just the external bolt on
stuff like alternators, etc.
I'm hoping Jim's engine will make that 200,000 mile mark.
BTW, Jim is a major aircooled aircooled builder in our area, abut his
WBX are great and are around $2800 up or down depending on what he can
re-use from your old engine.
