Hello, I just got my waste vegetable oil burner on the road and have had a problem. I changed the oil and filter one week ago. Today while driving I noticed the oil pressure drop from 3 down to 0 then back up and down intermittently. I got home and found that it was about 3 quarts low. I have driven roughly 500 miles in one week with no problems. I did notice some oil below the air filter housing last week and found the drain tube leading to the valve cover had come loose below the air filter. I reinserted the tube and thought I had corrected the problem. Today I found that there was oil on the manifold below the air filter housing but the drain tube was still in place. I thought that maybe the PCV valve was clogged but then I removed the rubber hose on top of the valve cover there was no PCV valve. This is my first diesel so I am still learning and unsure if there should be a PCV valve or not. I do see some smoking from the exhaust when starting but nothing that would suggest 3 quarts usage in a weeks time. Any advice would be appreciated until then i will keep toping it off! Thanks, Noel.
