For those of you sitting on the edge of your seat, I now give to you day two!
Got the manifold and head removed, found a few interesting things but nothing I would consider my smoking gun when it comes to the strange chirping noise........well one potential thing but we'll get to that.
So in doing a compression test the results were as follows and in order of the cylinders, 120, 115, 120, 110. So nothing too exciting there except that when I removed the spark plugs, all were dark/charred except for #4 which was nice and shiny just like it was when I cleaned it not long after getting this tractor but #4 was the cylinder that had extra oil and crud in it. It would occasionally burn a bit of oil so now I know it was #4 that has the oil control issue.
In looking at the head and gasket once removed I noted that it looks as though the 2 and 3 cylinders may have had a very small leak between them which might explain the chirp heard thru the exhaust........being as how the 2 and 3 piston travel together it would make sense that when one is at the top of it's compression stroke the other would be at the top of it's exhaust stroke and vice versa.........therefore if there were a leak between these two cylinders it would make sense that the compression from one is leaking out the exhaust of the other. BUT that does not explain the decent compression readings unless it's a VERY small leak.....and maybe it is/was I'm not sure.
Something else of interest on #4 is that the piston has a nick/burn/something amiss. In addition to it looking much dirtier than the other 3.
And for some reason the #1 piston is installed with the arrow towards the rear.
And last but not least, for Tony, the picture of the MHF202 from my service manual.
