low air pressure


Sir I have a TradesPro mod. 835486 1.3HP 5gal tank. It will only pump to 30/35 lbs. It has a lot of blowby coming out of the oil filler cap. This unit was working just fine and went from 100lbs to 30lbsIt has not run for 3 or 4 mo. It did this when restarted. The reed valves look to be OK. also piston rings cylinder look OK Can you tell me anything.Also price for rings piston and cylinder if you think this is what I need to fix.
