EA81 stalling....

[Al Blake]

the saga continues.....we had water dropping into the oil of a 1983 EA81 4AD
subaru. Head has been skimmed and replaced. Engine starts and runs fine
but...........

now the engine randomly stalls. You are driving along at normal speed and
without warning the car slows down come to a halt and stalls. You start the
engine and off you go again until the next time it happens. Never seen
anything like this before. Ignition seems good but I was wondering whether
during the head work something got disturbed and isnt happy any more

We removed the inlet manifold as a unit so it probably got moved for the
first time in 20+ years. - and the carby would have got juggeld about in the
process.

A friend mentioned the PCV valve as a possibility (I dont even know what
that is but I'm gonna find out).

Any other ideas?

My first thought was ignition, as in no or weak spark, then no or low fuel
pressure and then maybe a massive vacuum leak. But from your description
it sounds like you have no problem restarting the engine. I wonder if you
have an engine ground problem? You had to remove a lot of stuff to replace
the head gasket and also I would guess had to remove one or more ground
wires. may have overlooked one when putting everything back togather.
I'm not familiar with the EA81 engine and don't know how much of an engine
wiring harness it has but it is always worth the time to recheck all the
connections.
