hey everone
my '91 vert might be a water pumper, but i cant quite entirely tell. I live in MA, so today is the first day I was really able to do the other half of the fact finding i wanted to do, so here goes.

if it is nice and cold out and i'm starting up ma'car for the first time in the day, i get quite a bit of "white smoke" but it goes away as the car warms up. so previous to this, i just figured it was because the car was cold, and the accelerated warmup puts the car at 3000 rpm, so unlike most cars, its pumping through more fuel, and so making more condensation then most cars when warming up.

Roday was 60 or so, so when i turned the car on, i dashed outside to look at the exhaust and noticed nothing, then (i think the heater might have kicked on as i had left it on my previous outing) I saw a little bit of white (virtualy nothing) for a little bit, maybe a minute, before it dissapeared.

do I have the beginnings of a pumper sages? or is there another culprit I can look for.

also, my warmup is accompanied by an intermittant light "pink, " or "plink" sound coming from the engine(tach takes a mini dip on each one). Related?

thanks for any help!

 

Best way to tell is take out the spark plugs and have a friend crank it over while you look for moisture coming out of the holes.
