[QUOTE="TARM, post: 1021875, member: 578"] CEL ? You really have to get the codes pulled as it could be a number of things. UVCH, IPR, ICP, injector and or its orings, etc You could try unpluggin the ICP sensor and see what that does. Its on the driver's side head oil rail near the front. See if there is oil around the sensor connector. While you are at it check the lock nut on the IPR is tight and has not fllen off It is the back of the HPOP on driver side. For it to go out the way you said if it was an injector my guess would be oring/s tore thru. You say passenger side. You can pull one of the HPOP connector in the passenger side oil rail. hook a connector that you can attach your air compressor line to. Then with the VC off you can listen to which on it blowing air. You could also unhook the UVCH and crank the engine over with the VC off and see if one injector was puking oil as that would indicate a poppet seat issue ( worn injector itself). I like to start with the stuff that is the least work and go towards whats more work hence I would with codes or in your case those sensors then codes. Finally pull the VC. How many miles are on that engine, assuming orig injectors? [/QUOTE]
