I recently did an engine swap in my '90 Westy Auto Trans. I replaced the 2.1
liter Digifant and put a 2.1 with only 86k miles on it. I did head gaskets,
water pump, and a few other seals.

I put everything back together and the van starts, but will not idle. This
is beyond a basic timing setup- Even when the van runs it does so very
roughly. There appears to be a vacuum leak as well, but it does not seem to
be on the outside of the engine.

My biggest suspect is valves. Does anyone have experience with the Bentley
procedure for adjusting valves? I suspect they go overboard when they tell
you to turn the adjusting screw 2x after it hits the valve stem. It seems
like this is too tight and keeps the valves open for too long. I did their
procedure but I will try again today with them a little looser.

The push rods appear to be seated properly, but if anyone has tips on
ensuring that they are in place (its hard to look with a flashlight because
there is oil in the engine) that would be great.

The van is circulating coolant and all 4 plugs are firing.

Thanks,
Dan
