Engine 2.0 76
Rebuilt engine and should start it today. Pulled the plugs and filled oil. Cranked engine to get oil pressure but nothing. Pulled pressure switch and tested with compressed air works fine. Loosened oil filter and cranked again oil ran from filter, tightened filter and tried again.... Nothing. Oil type 20W 50 Need some advice on what to check to find source or problem.... It's just a Pita |

QUOTE(Geezer914 @ Apr 20 2015, 08:38 AM)  Why is it recommended NOT to fill the oil filter when trying to build up oil pressure??? (IMG:style_emoticons/default/confused24.gif) To prime this system, the pump needs to pull oil up from the sump. While it is doing this (for the very first time) the pump only has air to use as the "pumping medium". This is why it takes so long to prime. IF you are asking the pump to prime itself WHILE trying to push oil OUT of the filter, it will take longer. I think the best idea is to leave the filter off, and prime till oil is coming out of the filter bracket. Then you can put the filter on (ful OR empty) and continue to prime until you get pressure. |
