Ok so here it is. I recently went through a puddle that blew my motor and I went to the junkyard to buy new one. After installing the junkyard motor I got the Jeep started but it runs rough. It misfires and bucks then shuts off for about 20 minutes. I believe that it was the timing so I reset the timing and reinstalled the distributor. When I install the distributor I noticed that it would not one of with the number one post on the distributor cap its it's about a quarter inch behind. I know the distric annoying be installed one way so at this point I believe my timing chain might be stretched. Any thought or ideas on the subject would be so helpful. I have been at it for two weeks now. I live in san diego ca so if there are any xj pro's out there that would be awesome but any advise will help.
