on my e99 powerstroke it runs real rough at an idle and it doesent seam to have the power it had i was told that it might be the o-rings so i replaced the ones on the driverside today (dealer only had 4 sets) but it does have a lot of blow by and i am starting to think it mabe a hole in one of the pistons but not sure im going to get a compression gauge and check it tomorrow and depending on how that goes i am going to have a contribution test done does any one have any suggestions please and thank you
