I need to change my signature...don't even own a diesel anymore...

Just run it, injectors are expensive. Mine have been rattling for 50k and it's a little down on power. I was paranoid about them so I went to a local cummins shop and had my fuel pressure tested, they pulled the injectors and tested them also since I complained. They were still good so I wasted 300 bucks for nothing. The shop (cummins ) told me I would know when it was time to replace. Don't exactly know what they meant but I guess we will find out some day.

BIGRED7.3 when i first got my truck, (with 208,000 miles) i had oil all over the block and the axle, i was thinking it was the head gasket or valve cover gasket, but it ended up being the hose that goes from the breather on the valve cover, it was dry rotted and ripped almost all the way around.
