Most likley abswer is to much oil in the system. Try running it halfway between add and full and check it when it is HOT

Have a 1973 Ford and I was wondering can the oil leak from the stem of the disturber


TYes it can, although not common. there is an O-ring on the shaft that seals inside the dist. hole. You can replace it easily after removing the Dist.Make sure You leak is not coming from the the end seals of the intake manifold?

Why does oil pressure build up in the oil reservior


Did you add oil , engine is a dry sump, and reservoir oil tank will gravity feed and swamp crankcase, when sitting over winter. Also make sure tank is vented.

Why does oil pressure build up in oil reservior


Check for a pinched/blocked vent line.
Possible bad piston rings and over pressurizing the crank case (compression blow-by).
Overfilling the oil tank. Check with engine hot.
Also, it could be just a aged/dried up/ cracked o-ring.

Most likely too much oil in the system. Check it HOT and only have about half way between add and full. Definitely not more than the full mark.

Pressure is building up under valve cover. its pushing oil out. when opening oil cap lots of air comes out


either oil ports are clogged not allowing drainage? or compression is bypassing the rings placing it in the crankcase assy area, Meaning worn cylender or cracked ring most likely

Pressure inside oil tankl


All air compressor will build pressure in the oil reservoir. This is caused by blow-by past the piston rings. The reason all compressors have this is due to the relatively slow rpm that the compressor crank is turning. Unlike a car's engine that is turning so fast the compressed gas doesn't have time to leak by the rings.
To deal with this problem air compressors have a special oil fill cap that alows the pressurized air to be vented out of the oil reservoir chamber.

There are three reasons that you are having this problem. The first is you have a clocked oil cap vent. Second is you have the wrong type of oil cap.
The third is the bad one. If the problem is unrelated to the oil cap then it means there is more blow-by then the vent cap can handle. This would indicate that you have worn or broken rings and/or worn cylinder wall.

If your compressor is not old (low hours), then take a close look at the cap. If it has more then 2000 hours then you will most likely need to rebuild the compressor, depending on the make and model.
Hope this helps and good luck.

Low oil pressure


Your main crank bearings and crank cap bearings are probablly worn well above spec which means that the oil flow is going throught them to quick and your not getting resistance to build pressure which means you need a motor rebuild
