Have them check the engine timing on the camshaft. You stated that you had the camshaft replaced why was that done. On a 60 series if that was done it means something else is going way wrong since that is an overhead cam engine and to be honest a BITCH to work on. I had a 98 Century at Henderson Trucking that was a dog til they put on a new charge air cooler and hoses for the same there was a pinhole leak in it and that right there caused 90% of my probelms. Just because the leak is not visable does not mean there is not one is the system someplace. After that was fixed that 500 detroit mated to a super 10 would hang with the 550 cats up Parley grossed out at 80K considering the run before I needed to be towed to a shop due to a overheat shutdown.

 

for some strange reason the post i put up yesterday is gone?????? anyone else have this problem?

 

Same here marcell You might also want to have them do a leak down test also and look not assume that the roller did not bend a valve or hurt anything else in the head.

 

There are lots of possibilities, but 95% of low-power complaints that I've encountered were solved by fuel filters, an air filter, or a turbo boost pressure related problem(Charge air cooler, hoses, etc.) Since your truck gets serviced regularly, I'd check the turbo(make sure it spins freely), CAC, and all the hoses. Don't forget to check the small hose that goes from the bottom of the engine intake manifold to the air compressor intake. It's just a heater hose, but it's used for the compressor air intake. I've seen a lot of detroits lose their boost pressure there.

 

My post is gone too.

 

i just reposted info from yesterday...it was on here 3 hours ago now its gone?!??????????????/ :sad:

 

Hi, just to add to this subject regarding leaking charge air coolers, I work for a company called vestas aircoil who design and manufacture charge air coolers. It is known to block some of the leaking tubes, obviously the cooler will not perform to is usual but it allows things to limp along until total failure.
