D17 oil use again

   First of all thanks for all the advise when I wrote about this earlier.  I drove the tractor and mower home Sunday from my sons and it was 1.5 quarts low. (3 hour drive).  When I stopped and filled up with gas on the concrete I found oil on the concrete.  So thank God it's a leak. Why I didn't find it earlier i don't know.  But the clean oil on a clean surface didn't show up well.  It is leaking pretty fast.  Appears to be from the top of the oil pan in the rear.  I haven't just tried tightening the pan yet, but I figure I'll have to drop the pan and re-seal it. When the motor was out it was easier (evidentally not easy enough for me to get it sealed right).  I need to work on some leaks on the PS and will be removing the radiater.  Any tricks to getting that sealed well?? 
 Also have a rear axle seal leaking out the left brake hole.  Ahhh winter projects.

	I'll fix your oil leak if you put mine back together. LOL Be carefull to not overtighten the pan bolts. If you overtighten, the rail will warp and you could split the gasket. The original A-C service manual talks about measuring across the pan to make sure it isn't too wide. Aparently it must be a problem prying the pan off and stretching it. I'll have to look in the A-C manual tonight after work. I'm sure I read in there that it is a bunch easier to R&R the pan with the front off, especially with P/S. One thing you might try is put leak tracer dye in the oil and run the engine some. You'll need a U.V. light. You can get both the dye and light at NAPA. (commonly used for finding a/c leaks) That way you would confirm that it's the pan and not the rear main seal, or elsewhere.

	If you get the pan off, check flatness of the gasket surface with a good straight edge. My SIL can over tighten the pan bolts using a nut driver.

	The shop manual says to measure the pan across the arch. It should measure 4 7/8". I don't know for sure if it would or not on a gas. On a diesel, absolutely. Is there a plate bolted to the back of the engine that fully encloses the end of the crankshaft?
