have fun

 

thanks haha

 

Hi, new here. Found the site by doing a search on Duramax injectors.

2500HeavyDuty,

Couple of questions on this excelent post.

Have a 2002 Duramax. Injectors were replaced at 77k miles, and 160k miles under warranty. Now have 210k miles and this time I get to pay someone else to do it or do it myself. Reading your post, I feel pretty confident that I can do it myself, as I spent about 7 years as a GM mechanic back in the 80's.

So here's what I'm not sure about.

a) is there a parts list for this job... what do I need besides injectors?

b) I see several folks talking about using bigger injectors. Is there any advantage to this besides more power? Will they last longer? My Dmax has been an excellent truck and other than this issue, I have no complaints. I use it to tow a 10,000 lb boat, a 16' cargo trailer, and a 5,000 lb boat. I love the truck and want to keep it till it falls apart or 300,000 miles... whichever comes first, LOL, and my injectors seem to last 60k-80k miles which means I'll probably be doing this again. My truck is bone stock and does everything I've asked of it, so not really interested in installing different injectors unless they'll last longer.

Thank you for the post!!!!!

 

For the Parts list you will need injectors, a set of copper washers, O-rings (the washers and o rings should some with the injectors), injector return line seals (eight injectors ones and two for the heads), The rubber gasket for the lower valve cover is typically re-useable, a bottle of silocone sealent for the upper valve cover.

If the cups get pulled out you will need two new orange o-rings and special sealent to reseal it.



Larger injectors will help you get in more fuel in less ammount of time and require less timing. Its a good upgrade for people who want to go to the next level in performance, but fwiw if your are not looking to make alot of power then the stock ones are fine.

if it helps you can find a shop or company that will sell you injectors with a one year warrenty, and dont buy from pensacola.

as for longevity keep ur filters clean

 

Should I buy GM injectors or is there an aftermarket version available?

 

i bought my injectors from the dealer, for you they would be 350 a piece. maybe one of the vendors here can get you them at a better price that are new with a 1 year warrenty.

 

Nice work Danno.

 

FWIW, I found them from an online GM dealer for 201.25 ea. I've purchased stuff from them before, so I know they're legit.

Still searching to see if I can find them cheaper.

thank you much for your help.

 

Nice write up. I just got done doing two in my truck.
