I was wondering since I am replacing valve cover gaskets, and am going to have to remove the turbo and the exhaust, should I be replacing the glow plugs and the injectors. The truck was running just fine before I removed the intake to replace the valve covers. The truck has around 150,000, where would be a good place to purchase replacement parts?
I've been reading the threads on this site and the pdm has not been moved on my truck. I'm wondering if it is working. Should I buy replacement pdm and move to bumper? IF pdm is not working, does that mean the fuel pump/transfer pump is not working and has been running on injection pump? Like I say, truck was starting and running fine. This is all new to me, any help is greatly appreciated.

 

not sure how many miles you got on the truck if you have 100,000 miles on it time to replace the injectors

for PMD you want to move it to front bumper if it still on the injector get off there move it to bumper

 

x2 but only use geniue bosch injectors and i recommened bosch duratherms for glowplugs
