/ The guy that put the engine internals together says "The rings are not seated yet end the smoking is normal. Just give it a couple hours of work"
#1
The engine only has about 30 or 45 minutes of runtime on it right now and that is basically been slow and fast idle. It is boiling black oil out of the exhaust manifold that runs down the engine. He said since it is Florida that it is not necessary to put a thermostat in it. I noticed that it never warmed up more than 110 or 120°. I put the thermostat in it and let it warm up to normal operating temperatures. When it warms up to normal temperatures the low oil pressure alarm goes off when the idle goes below 1000 RPMs. This coincides with a manual oil pressure gauge that I put on the side of the engine. We trailered it over to his shop and he said that the oil pressure is normal that it should be about 10 psi per 1000 RPMs. So at 1000 RPMs an oil pressure of 10 psi would be OK. He suggested using Lucas oil treatment and thicker oil. It currently has 15 W 40 oil in it. In his defense he ran the tractor around the property for a short time while riding the brakes to put some stress on the engine and it did seem like it was smoking less. The oil pressure issue remains the same. So my question is what is a good oil pressure at an idle on a brand new engine. I understand that a new engine will smoke when it is first started. How much is too much how long before it should stop or go down to the minimum. I am certainly not an engine rebuilder but I have done everything on this tractor except for actually assembling the internals of the engine. I feel a little bit uncomfortable about putting a big bush hog on it and running it for a couple hours without checking with someone else to see how they feel. What do you think. Thanks for your time and attention. OK
Sorry I should have included that information from the beginning.
-Bored 040 over
-Machined Crank
-New Pistons all
-New Rods all (one was bent)
-New Rings
-New Injectors
-New Valves
-New Guides
-New Oil Pump
-New Cam Bearings
-Lifters looked perfect just cleaned
-Push rods checked and re-used
-New Idler timing Gear
-New Water Pump
-New Radiator
I dealt with the machine shop dropped and picked up. The machine shop got the Reliant rebuild kit and did the cam bearings, the rings were installed when I got the pistons in the boxes. They said everything was correct and ready for assembly. I have done mechanical work since I can remember and do pretty well on any project BUT, I wanted an experience builder to actually put it together. I have put engines together but I am NOT "The Engine Guy"
The guy that put the internals together came to my shop with his father and put it together. I had everything cleaned, labeled, and laid out on a table like a surgery before the doctor gets there. I watched them and waited on his every request (tools, bolts, supplies...etc). He seemed to know what he was doing. No big red flags on the build.
