Don Jordan Posted February 24, 2008 Report Posted February 24, 2008 I've seen white smoke when they elect a pope and I guess that's a good thing. I was out for a drive today in my 47. Going down hill when I take my foot off the gas lots of white smoke. Is that rings? I haven't done a compression test yet (I'm waiting for it to warm up). That should tell me shouldn't it? Does the 47 218 have babbet bearings or inserts? I know once I start with one thing it ends up being everything. Quote
grey beard Posted February 24, 2008 Report Posted February 24, 2008 Hi Don, White smoke in significant quantities usually means antifreeze or coolant is getting into the combustion chamber. This can readily be veified with a quick compression check. When you pull 'em, look also for a very CLEAN spark plug that may indicate coolant fouling. Having said this, if your engine was not completely warmed up, and you noticed it only on deceleration, I would not panic at all untill it has some significant miles at operating temp on the engine. If the white smoke is still evident then, it is time for a little serious diagnosis. Light blue smoke - which usually means burning oil - can appear to be whitish, but a little road time and maybe a friend following behind as an observer - on a well-warmed up engine - should put you on the right track. JMHO:) Quote
james curl Posted February 24, 2008 Report Posted February 24, 2008 On a well-worn engine on de-acceleration if you get what appears as white smoke when you start to accelerate again then the rings are usually worn out. Quote
Plymouthy Adams Posted February 24, 2008 Report Posted February 24, 2008 the mopar 6 has had inserts from the get go... Quote
Don Jordan Posted February 24, 2008 Author Report Posted February 24, 2008 Inserts - that's the good news. Are they available? And before I get too anxious are rings available? I don't think Chevy had insert bearings until 54 - that's just a guess. Quote
Plymouthy Adams Posted February 24, 2008 Report Posted February 24, 2008 chevy was behind the time..that is why so many chevy bodies exist today..babbit rods failed..cost to repair high..cars were parked cause you could not sell a car with a failed engine..now the old Mopars ran and ran and well just flat out used up for the most part...

Joe Flanagan Posted February 24, 2008 Report Posted February 24, 2008 Don, You can get pretty much all the parts for you engine at Vintage Power Wagons. When I rebuilt mine I got all my stuff there. Quote
