I was out playing with my 8n looking for the source of a couple of leaks and discovered some other not good stuff. First the leaks. I have one that looks fairly easy to fix on the governor, appears to be just a bad gasket. The other one is on the oil pan on the left side in the front. The bolts are pretty snug so I think it is a blown gasket. How difficult is the oil pan gasket to replace? I was planing on removing th front axle for new bushings anyway so it will already be off, and if I understand the manual I don't have to split the tractor to do it. Now the bad stuff. I had been suspecting a bad spark plug for a while. I pulled them to clean them and still had the miss. I then pulled the wires off individualy,and found the #3 and #4 wires cand be off with no change in engine performance. Not good. plenty of spark with a grounded plug though. I don't have a screw in type compression tester, but will get one before the weekend, so no compression test results. So my plan is to do the wet/dry test first. If I have little to no compression on the two adjoining cylinders would my prime suspect be a blown head gasket? If not and I am lookig for sticking valves do I check that with the head off or is that done with the valve cover off the side of the engine? Thanks, Andy

Andy,

Be Careful! That pan is heavy!

I've seen postings here that you can check for valves sticking by looking through the side covers. Makes sense to me. You can also free a sticking valve sometimes by soaking it with MMO through the side openings.

Definitely do the compression tests. But I would replace the spark plugs too unless they are real new - old plugs sometimes fire fine until they are under load.

with the front end already off the oil pan comes off very easy (mine did anyway)just take out bolts and I used a paint scraper to get it started then a screwdriver to help it and it came off very easy

Are you sure the wireing is correct on the distributer? The fireing order is 1 2 4 3 counter clock wise. #1 is top left. Try changing the two wires and see what you get.
