OIL TEMP TOO HIGH
Thanks for your response,
I built two 400 small blocks for a boat w/.20 over with JE pistons 9.0 comp,bore to piston .005 clearance ,standard rings .002 extra clearance on the ring gap, cranks cut to .10 under size, I checked every journal with plastic gauge and the clearance is on the loose side. I also installed a high volume pump w/ six quarts in the oil pan (mobil 1).
The engines rpm stays around 3000 with a max of 4200. I installed a set of world cyl heads and a oil cooler (water to oil). The fuel mixture is great I checked it with an oxygen sensor. The engine water temp is 160.
The idea of the exhaust near the oil filter was great but not for my application. The exhaust on the vessel is water cooled. I feel I covered all my bases but I still deep frying. I have the bypass valves blocked. The timing is perfect and some one else mentioned to me that blow bye could also do this but I don't have much at all. When building these engines I really took my time and double checked all clearances. Please help..............
