pairrothead01 I saw you mentioned you had to replace the water outlet hose going to the water control valve. I think I might also need to replace this. I have a coolant leak and have removed the upper intake plenum and the lower one. After removing them I noticed a puddle of coolant in the valley of the engine V. I have not yet removed the last part of the intake that mounts to the head as it started to rain and I don't have a garage so i quickly reinstalled everything. I have a feeling it is either the gasket on the outlet or the hose that goes to the water control valve. Does this sound similar to what you encountered? Just trying to see if I'm headed in the right direction. Thank you

Did the o ring solve the leak. That sane spot on my 02 is basically covered in built up oil sludge/residue. I had been thinking that it was either the camshaft position sensor or the vvt solenoid. Had planned on replacing the vvt gasket and the o ring on the cam sensor just curious if it solved your problem.

Hello, new member here. I have a 2002 pathfinder sec4x4 with 3.5 and a/t and 230k miles. I've been trying to diagnose an ac problem. The ac would be cold and work fine and then other times it will only blow hot air. I hooked up manifold gauges and I was getting high low pressure side #s (120 psi) and low high pressure # (under 90 psi). I suspected a possible clog. I evacuated and pulled vacum and refilled with as close to exact .99lb r134a as possible using scales. It then worked fine for a day then back to intermittent warm then cold. Usually if it was cold it would stay cold for the day even with starting and stopping the car running. When I pulled the vacum I held it for 1 hour and it dropped .5" mercury. I figured that could have been connection of manifold gauges. When the air was blowing hot the suction line was hot. So I again assumed clog. I replaced the condenser and expansion valve. Bingo, great very cold air. Now 2 days later I'm back to high low side pressure and low high side pressure. Static pressure with car off for 1 hour are 90/90 with ambient temperature of 80. Any help would be greatly appreciated. Thank you
