135 oil leak

Hope I am posting within the forum guidelines? I hope it's Okay to start a new topic about the same tractor. Recently posted that I purchased a MF 135 and had some questions about getting it up and running (which it is now.)
On to my most recent issue, the 135 is leaking oil. There is what appears to be a small (maybe 1/8") weep hole just below where the tach cable connects to the engine, when I start the tractor this hole starts puking a steady stream of oil????
 
If you are operating a 3 CYLINDER PERKINS DIESEL Engine,(A3.152..AD3.152) or a gas Perkins? with the same tack drive arrangement then this info may interest you? If you PLUG the weep hole, you shall be allowing engine OIL to pressurize the TACH.DRIVE connector. "OIL SHALL" work it's way up the TACH.Cable and pressurize the TACHCOMETER! The weep hole is telling you, the OIL SEAL on the REAR of the CAMSHAFT requires attention/replacing. The last seal I replaced,I had to installed a SPEEDY SLEEVE on the CAMSHAFT, as the SEAL had worn a GROOVE in the matting surface of the peripheral of the CAMSHAFT. Here are several PICS. I have NEVER installed a SPEED SLEEVE other than on a COMPLETET overhaul. The seal can be replaced by removing the 3 CAP screws that attach the TACH.CABLE connector to the rear of the engine block. Possibly only the SEAL requires replacing.

Chances are it has a 40+ year old seal that just needs replacing in the tach drive cap. MF part number 636762M1 Seal, Housing To Block (7/8 X 1-3/8 X 1/4") (Perkins No. 30854).
 
Thanks guys, called the local tractor dealer and he has the
seal and gasket in stock I will pick them up tomorrow.

Installed the tach seal, solved the oil leak! The seal was only about $2.50 the gasket was almost $10.00? Tractor is running good now with no leaks. Plan to drain and replace all fluids. Purchased NAPA hydrolic/trans fluid and engine oil, just need the get some coolant and find some things me.
