I've got a 4L MPFI EBII, and just recently, its been running at fairly high temperatures, for example, 110 down the highway on a 15 degree day, and its on mid-temp! then i have to watch out when i turn off the engine, as the radiator starts to bubble and the temp slowly rises. Now my bottom end seals are stuffed, sorta, and im getting a new engine rebuilt as we speak.
Now, could this sudden temp problem be caused by the worn engine? or would it still have to do with the cooling system?
Soon to come: Full engine rebuild, Race pistons, Performance cam, Full Defillipo Performance Exhaust
