Low Power, Fuel Mileage Drop - Help Please

There is a rubber gasket between the compressor of the turbo and the metal neck that mounts to the first boot you can check there you would have to take that clamp off. Have you also just to see, take the air box hose loose from the turbo and look at the comppressor wheel? See if it spins freely by hand. I have had one build up rust on the exhaust side and just not turn had to take the turbo apart and free the exhaust wheel to get it to work.

When you set up a boost gauge where does it get connected at or how do you set it up to take a pressure reading?

With the eigine at idle speed and the intake piping to the air cleaner all in place, take a can of starting fluid (either) and spray all the intake piping, intercooler and intake side of the engine including the plates in the head where the last aluminum cast elbow is, if there is a leak the engine will rev due to the either.Rocky

There is a port on the manifold right below the intake neck its hard to see but look there its probably in the sticky note about hooking up a boost guage.

1arock has a good method there it will tell you where its at

Is your air dog working correctly? low fuel pressure (flow) can cause this. hopefully you have not hurt the engine driving it so far smoking like that. possible to burn a valve or piston like that. A way to check that is a compression test. First check your fuel pressure, flow and then check your boost. on a stock truck I believe 15 to 20psi. is pretty norm... Well have to be under load to show any boost.

I hope you are not right but after the trip I started the truck for the first time this morning... At first it didn't want to start at all and then I had a weird clacking or noise I couldn't figure out that was not there before. That's all I need now.

Could have blown a tip off of an injector. Poor atomization will cause low power while pouring black smoke. Ether sounds like a good idea but from my experience even at idle if you take the plug out of the head air flows from the hole, meaning the head and piping is all under positive pressure at all times. Kind of hard to pull ether thru a hole when the system doesn't ever run under a vacuum. It'd have to be a pretty substantial hole for it to work as intended. Lots if soapy water.

Ok pull the clamp from the turbo outlet and turn the elbow away from it first, it will work I've done it.Rocky
