I have a Deere 4020 that we overhauled for a neighbor last summer. We ran it about three hours fixing some other problems and it started putting some oil out the exhaust manifold. We replaced the metal exhaust gaskets that Deere now uses with the old original type and borrowed a dyno and broke in the engine like company said. Told the owner to use it and not let it set and idle. He did not work it at all and called that it is leaking oil out the exhaust manifold gaskets. Went and got it today and now have it on the dyno running at about 90 hp. All the oil is now burnt but we still have to much blowby for a new engine.It is a Reliance engine kit and all the machine shop work (head ect) was done by a top of the line shop.I wonder if the rings are to hard and will never seat? I do not think it is a broken ring as it was leaking out several of the exhaust manifold gaskets.I could pull it down but would have to buy new gaskets and head bolts as we used the new torque to yeild bolts.I read or heard years ago that Cat made a product years ago that you would dump in the air cleaner. It was something like Comet and would cut the rings some? Anybody else ever heard of it? Anyone have any other ideas what to try. Tom

One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I’m handing him tools and he says, "give me that..." and I’ve already got it in his hand or "hand me that....."and I’ve got the portable light right where he needed it placed to see. "Run in the house and get me a...."as I open th
