I was just at the San Antonio, TX Rush Perterbilt today and they are advertising an overhead special with PM Service (Oil change, oil filter, fuel filter & lube) for $300 out the door, they claim it's a $400 savings and the offer is good until the end of the year. The service guy also said they will throw in a "21 point" inspection too although I didn't have time to ask him what that consisted of. Will more than like head back there tomorrow or the day after and have it done.

$300 is an AWSOME price on any engine for an overhead and PM.

Yeah that's what I was thinking. My truck has 521k+ on it and I doubt that it's ever been done before so tomorrow I am heading over to the shop to "git-er-done"

I.c. t.y.

My problem with this truck is loss of power. The reason I was asking about overhead service is because I've tried everything else I can think of. The injectors were replaced. The motor was hooked up to the computer at the Cat house and everything checked out perfect and they even updated it with the most up to date software. I had my air to air checked thoroughly for leaks and all was fine there too. The truck is not consuming excessive oil, it's not smoking. Only thing I can think of is maybe some sort of problem with the turbo. I'm open for suggestions. The motor is a 3126B and it's supposed to put out 300 hp which it did when I bought it 3 years ago but slowly it has lost power. It feels like about 200 hp now. It has 500k on it. I've put about 175k on it in 3 years. It's a dump truck that never touches the interstate. I rarely run it over 60mph. It's mostly 20-30 mile short hauls. I even replaced the radiator. It never runs over 200 degrees even on a 100 degree day. Any help would be appreciated.

Have you charge air cooler tested. If it's leaking air then you are loosing compression and horsepower.

Things to check:

Charge air cooler for leaks- You have done this already. Did they give you a psi drop over 1 min?

Boost output under load- Take a look at your gauge to see your maximum boost psi. If you see a decrease over time you could have waste gate or boost leak issues.

Injectors not atomizing fuel properly - injectors are getting worn out and are in need of an exchange- Expensive!

Compression issues- Check for excessive oil consumption and blow by at the blow by tube near your oil pan when your engine is at operating temperature.

Top end set- will not give you noticeable horsepower or fuel savings. Maintenance reasons only. As valves recede into the head it decreases valve lash between the valve bridge and the rocker arm. Each top end set should be performed at 250,000 miles for regular service trucks. For trucks that are severe service and use engine brakes often should be done a little sooner.
