Don't run it this way. You will ruin the bearings. It may be a head gasket leaking also. Pull plugs see if one look different than the others. Usually it is he intake leaking. I am not crazy about the "turkey trays" especially with the aluminim intake. Use Mr. Gaskets intake gaskets. Get it CLEAN! CLEAN,CLEAN,CLEAN, did I tell you that the heads, block & intake must be clean? Clean front/back of intake underneath where front/back engine rail will be. After it is CLEAN, take rubbing alcohle and clean it some more. I like using a product called Gasket Cinch, hard to find in parts stores, I buy it at the Honda shop. Also us RV sealer instead of the rubber rail gaskets. Do the gaskets with the Cinch both sides, wait 5 min's, do again, wait 10 min's put the on the heads. I Cinch them and hang them on a wire while waiting. Put bead of RV on front/rear rail lapping a bit onto the gasket, I make the bead about a 1/2" high, Put intake on carefully, Nice the have new or really clean bolts, The bolts by the water ports smear some RV on them, just in case they go through into water jacket, I think one may. Thighten starting in center, in stages working across front/back, TORQUE in stages, and don't over thighten, let it set a couple hours and recheck torque. I always take gooseneck off and fill radiator letting block fill to gooseneck opening the put a new gooseneck/thrmostat gasket. Change oil/filter. After running to normal temp, shut off, Let it completely cool, check oil for water, retorque intake. Good luck, Ken
