Hi, I'm new to the forum and I'm very impressed with all the info available. I have a problem with my 1987 FJ 60. The Oil filter has blown apart three times now in the last 2 years. The threaded part stays on the mount, but the entire outer shell comes off, along with all of the oil of course. Each time I put a new one on It will last a few months and than blow off. There is a pressure relief valve on the oil filter mount, which I have removed and inspected, but it does not appear to be damaged and it appears to be freely moving. Also the spring looks O.K. The oil pressure gauge appears to working properly (The pressure stays within the normal range). As a side note the Toyota Dealer gave me a diagram of where to find the pressure relief valve for the oil pump but I can't find it. I should be able to access it from the outside of the engine on the lower left side. Do I need to remove the oil pan? Can anyone offer any suggestions? Its a 2H engine.
