I just installed my head on my car and tightened up all the nuts and bolts and the 4 oilers on the top of the head that squirt oil are hitting the valve cover for some reason. its a loud ticking noise from the valves squirtters moving up and down and hitting the cover. Is there something i did wrong? Can i just remove the squirtters or do they have to be in there? My friend had a regular dx civic and his doesnt even have the oil squirtters. Any suggestions would be helpful. thank you.
