95k1500 Posted December 11, 2007 Share Posted December 11, 2007 My "B" with an END 673 engine will blow oil out of the exhaust. When I got the truck this problem was not evident. The engine ran fine, and still seems to run fine and strong. The truck has really not been driven in a number of years. Not long after I had purchased the truck, I had to relocate it to another home. This was about a six mile ride; during the ride it blew oil out of the exhaust. It ended up all over the windshield of my pickup which was following this ride home. So the question is... what could be causing this? What is the cure? Is it anything to be worried about? Is it just a product of sitting for a long while? Some other info...the engine is a remack installed 6-72 unkown miles, but believed to minimal, no water in oil, etc. Any info would be great! Thanks!Dave Quote Link to comment https://www.bigmacktrucks.com/topic/3188-oil-in-exhaust-673/ Share on other sites More sharing options...
scooter Posted December 11, 2007 Share Posted December 11, 2007 I forget if your engine has a turbo but that much oil it can only be the turbo! Don't know the seals would go out from just sittingcuz they are metal ring type seal. If you don't have a turbo the oil rings are gummed up and need to be unfrozen, either by driving or oil additives or the unthinkable (inframe) Quote Link to comment https://www.bigmacktrucks.com/topic/3188-oil-in-exhaust-673/#findComment-15668 Share on other sites More sharing options...

I would like to think, the rings would be gummed up as you said. I would hate to have to inframe, but now is the time to do so if needed.Any other thoughts?Dave Quote Link to comment https://www.bigmacktrucks.com/topic/3188-oil-in-exhaust-673/#findComment-15673 Share on other sites More sharing options...

Most of its run time has been in and out of the building. Usaully try to bring throttle up if it is going to sit and run.Dave Quote Link to comment https://www.bigmacktrucks.com/topic/3188-oil-in-exhaust-673/#findComment-15675 Share on other sites More sharing options...
gvam Posted December 12, 2007 Share Posted December 12, 2007 I have used Marvels Mystery oil when I have had a similar problem in a couple of farm tractors I have worked on. Had good luck with it. Probably the same type thing as adding Rislone. Just my few thoughts Quote Link to comment https://www.bigmacktrucks.com/topic/3188-oil-in-exhaust-673/#findComment-15680 Share on other sites More sharing options...

Kav Posted December 18, 2007 Share Posted December 18, 2007 I was thinking about the sea foam, as an additive because I happen to have a couple of cans the the shed!DaveWhat is the sea foam that you use. When we used to have this problem from excess idling in a paddock loading bags of potatoes. we used to drop the oil out and do about a thousand miles with Castrol hydraulic oil in the motor. This used to bed the rings in again. The other way to cut the glaze was to put a couple of teaspoons of Bon Ami cleanser into the inlet manifold while the engine is running. You cant do this too often as it will wear the rings out. The old Caterpillar books used to describe this in detail. If your rings are totally gummed up, some of the newer additives would be better. Heavy work is the best cure.Michael. Quote Link to comment https://www.bigmacktrucks.com/topic/3188-oil-in-exhaust-673/#findComment-15783 Share on other sites More sharing options...

I have seen that done many years ago when the engines had a ring break in problem even seen fine dust off of top of stove used. glenn Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/3188-oil-in-exhaust-673/#findComment-15785 Share on other sites More sharing options...
