I have been reading several threads lately of members trucks surging.
Mine for the last 2 weeks has had a slight surge. I can even see it in the boost
gauge when I start off and the rpm's are low.
I had my diesel tech take a ride with me and he felt that my turbo probably
had some carbon build-up. So I finally dug in and began to take my turbo out
and do it myself to save some money and to also have an opportunity to learn.
I consulted my diesel tech on how to go about taking it out of the truck and
he also gave me some good tips on what combination of tools to use for those tight spots.
Below are some pics of the internals and how they looked during the resurfacing steps.
Thanks for posting. Your turbo looks just fine. How many miles do you have on it? Were they city, highway and what percentage were towing miles?
Almost all my miles are freeway miles and i have noticed with a fuel additive like Amsoil that the turbo seems to operate pretty smoothly. I did have some of what you were describing when my truck was nes and after city driving.
