the last 2 words in the post before are very important the diesel bugs can not exist without water so no water no bugs,use see thru bowls on bulk diesel tanks so you can see if water is present,if you do not have a see thru filter system get in the habit of using the petcock to drain off a sample for inspection.

I stand corrected it has been a couple of years since I seen that can and I mistakenly thought that I remembered seeing ppg as the parent company of valspar.oops

I know they use them on logging skidders all 4 wheels,but I do not think I have ever seen good tires on a skidder unless it is new on the lot for sale,I think the key to not tearing up a tire is to make sure you get a correct fit with the chain.

I just fixed a couple months ago a john deere 655 (yanmar) I think that was the model with the same set up on the valve .He had overheated the engine and I think that made those o rings brittle so they started weeping .In the bottom of the hole that those valves came from there should be a copper compression sealing washer,that I think is the main seal to prevent leaks the o ring must take care of a lower pressure flow. replace all with the sealing parts with new ones replacing just the o rings might not take care of the leak,I know this by trying not to replace the copper sealing washers,I would try a diesel injector shop for the parts if they are not on a parts breakdown you have. lube the o ring with just diesel.

I assume you got all the caps back on pointing in the same direction as they came off. and maybe a different oil pump will make adjusting the oil pressure relief valve necessary.but now thinking was the engine run with low oil or no oil maybe you need to plasticgauge the bearings.
