Had the same problem on my '88 GL. Dennis clued me in. Pulled out
sufficient oil to get it halfway between 5he marks. Now no more problem.
One other thing - every time I dropped from highway speed to idle, say at a
stop light, in my CARAT with the auto-tranny, the oil light would come on.
Nerve racking! Dennis clued me in there too. Raised the rpm by 50 and no
more problem. For some reason the WBX 2.1L engine when mounted to an
auto-tranny just needs that extra 50 rpm to keep oil pump pressure where it
needs to be.
