I need some help! On a carberated 5.0 I have medium amount of white smoke from the passenger sidepipe while idling and low revs. Haven't had it on the road to know about under load. No smoke out of driver's side. Replaced carberator and plugs. Old plugs looked clean. Compression check was as follows:
1 = 137lbs
2 = 145lbs
3 = 147lbs
4 = 135lbs
Check done at normal operating temp. Is this a valve guide problem, and if so, why are the pulgs clean?
