O. K. The 1550 diesel will have rotators on the intake valves. Here is what you do. Take the intake manifold off and have someone turn the engine over with a socket and a bar slowly. While the engine is being turned over look at the valve stems when each valve is open. See how oily they are. We put P/C valve seals on many Oliver engines and it was a field fix for the older engines after they became standard. Also there are 2 1550 diesel heads (different valve sizes) How about a tractor and engine serial number in case you have more questions. You can also change valve seals without removing the head. Your questions? Oh: when you take the valve cover off look for sticking exhaust valves as well. J.

Hello J. I have just yesterday taken off valve cover and checked valve lash settings do to excesive smoking and running rough. I'm suspious of bad injectors or pump but trying to eliminate other possible causes first. All were moving and lash was pretty good, did ajust a couple. I'll do as you suggested with intake and check valve stems tommorow. When I was putting valve cover back on notice that side was quite oily/dirty. Thought it could be Energy Cells leaking. Cleaned area and ran it today for 1/2 hour feeding. After that noticed seepage from intake. Tractor Serial # 355=42007 #'s off engine behind starter 185320 and 160913A. Tell me more about these P/C valve seals and procedure for installing them please. Also Would like to test pump preasure, could use advice on that. Rocko.
