Yeap, it can be quite a few things... but like you / I said, when you
have spare parts to do some testing, you (90%) find the problem quickly
and effortlessly (if my English is good). Anyway, we are reading
"symptom" of a problem on a mailling list. Everything you say or other
says are assumption, like alsways.
Dificult to diagnose without a smell, noise and feel. I personnaly have
to look, feel, look, listen and smell an engine to began some testing.
If i had this van in my shop... it would take me 30 minutes max to find
the problem. Why, because i have over 10 Vanagons in parts available.
Swaping is way more fast then reading and testing.
I have to think more, i have seen that problem more then once.
Anyway, i'm sick like hell (cold) so i should go to bed... i hate Canada
weather, another 12in of snow tonight, 70mph wind.... beuaaaaaarrrkkk.
I will move to the US sometime.... soon i hope. When Bush is out!!! ha
ha ha ha... just a JOKE!!!
Where is Mexico when i need it! :-)
Regards, Ben
