OIL PRESSURE BETWEEN 35 PSI @ IDLE -55-60 PSI@ OPERATING SPEED..:irked:

That "wire mesh filter" you identified is the crankcase breather. It requires periodic cleaning. If this is not already part of your maintenance schedule, I recommend you remove it and wash with kerosene at least yearly. Consider also that the engine oil filter may be bypassing. Doesn't cost much to replace it. May as well change the oil while you're at it. Also, remove the valve cover and wash it out. Then use a paint brush to wash away the crud on and around the valves. You'll then find a few oil ports, where splash lubrication passes between head and crankcase. One or more may need unblocking. Because of the potential of contaminating the crankcase with kerosene, this should be done before you change the oil and filter.

I changed oil in a Jinma 254 that I had just bought and it smoked and blew oil out the crank case breather just like you are saying. I had put in 6 1/2 qts like it called for. That was too much oil. I redid it and it actually held just over 5 qts. No more smoke and no blow by. Pat
