Title: CHEROKEE 2.8 CRD INJECTOR SEAL
Post by: Mouse on December 27, 2010, 12:49:23 PM
I've just removed No. 1 injector as it had air blowing up past it and expected to see a Copper washer at the base of it. All I found was half a Rubber 'O'Ring about 30mm up the injector. Can anyone tell me if this is correct or should there be a copper washer at the bottom to seal it.Thanks in anticipation.Mouse

Mine runs the copper washers and I need some new ones as I have 1 blowing but they are on back order at the min.

I have not seen a rubber "O" ring before but I have only looked at my own Jeep and no others.

Just fitted new Rubber 'O' Rinr and sourced a copper washer and it is now running better than it has since I've owned it, I can only think someone took the injector out before and never fitted the copper washer when they refitted it. I hope this has now cured my misfire when hot.

Result, could you let me know what size the O ring was and the washer you got ?
