JIPJOBXX Posted September 8, 2011 Author Report Share Posted September 8, 2011 I think I fixed the problem as I really never did a through cleaning of that breather cap. I just got back from a 30 miles drive and no problems what so ever. May it was the breather cap? Thanks guys for the help! Jon:cool: Quote Link to comment Share on other sites More sharing options...
Joe Flanagan Posted September 8, 2011 Report Share Posted September 8, 2011 Sh!& siding? No, never heard of that. I'll bet dirt-poor people had that kind of siding. Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted September 8, 2011 Report Share Posted September 8, 2011 Sh!& siding? No, never heard of that. I'll bet dirt-poor people had that kind of siding. Some old timers need to chime in here but that siding was common to many homes in the 40's and 50's. Quote Link to comment Share on other sites More sharing options...

ActionGrant Posted September 9, 2011 Report Share Posted September 9, 2011 I'm actually having an extremely similar problem. (1951 DeSoto Custom with the 251 Flat 6) I took a video of the problem, hopefully you guys can shed some light on this problem for me. It seems to smoke more when the car is in gear and not moving (e.g. going up to a traffic light), and that is how this video was made. Any thoughts would be greatly appreciated! - Grant Quote Link to comment Share on other sites More sharing options...
greg g Posted September 9, 2011 Report Share Posted September 9, 2011 (edited) were you to do a compression test of the engine cylinders, I would bet that you would have readngs in the 70 to 80 range. An engine in new condition would have about 110 to 120 per cylinder. The rest of yours is passing the piston rings and pressurizing the crankcase. This is commonly attriuted to worn or broken piston rings, and taper worn cylinders. Many of these engines will actually have rigs broken so badly, that they may have also broken the top of the pistons as well. Your engine can run for years like this, or you can chose to have it rebuilt, or at least, bore the cylinders and buy new pistons and rings sized to the new demensions. the other critical indicator of the condition of the internals of your engine are oil usage, oil pressure, and manifold vacuum reading and interpretation.

Dodgeb4ya Posted September 9, 2011 Report Share Posted September 9, 2011 My goodness what a sick DeSota! Quote Link to comment Share on other sites More sharing options...
ActionGrant Posted September 10, 2011 Report Share Posted September 10, 2011 Well it only has 34,000 miles on it, so I was thinking it might be valve related. Is it possible for this to be caused by something like that? Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted September 10, 2011 Report Share Posted September 10, 2011 (edited) That DeSoto kinda sounded like it had a stuck valve-intake and or exhaust and maybe some piston and ring damage. Compression check time. Edited September 10, 2011 by Dodgeb4ya Quote Link to comment Share on other sites More sharing options...
greg g Posted September 10, 2011 Report Share Posted September 10, 2011 get a vacuum gauge and see what you find. Oil smoke and condesation fumes come from the crankcase not the intake exhaust area. Although a stuck/burnt valve will effect how it runs, it will nor cause the breathers to belch. Again a vacuum gauge and compression gauge reading will answer a lot of your questions.
