10-12 PSI at WOT

Just bought an '05 knowing that it had a boost problem. Checked the boots and they all look good. There is a really faint sound coming from the turbo area. Also, it doesn't seem like it is spooling up right. I'm not new to diesels, but I've never had a turbo problem. Am I looking at removing the turbo and replacing seals or something a little easier? I've tried using the search feature, but I don't come up with a whole lot. Thanks,

David

I would say pull the turbo and clean it... While doing that inspect the up pipes for cracks. When you install make sure the turbo is lined up on up pipe flange. Sounds like you have a leak on the exhaust side if your boots are tight. You can also use a some soapy water in a spray bottle and test each connection. I'd say exhaust side though...

I did had a turbo on Mercedes not spooling right and even when I pulled it out, I could not figure out how to take it apart. But I did have a bucket of grease cleaning solvent (the stuff that in those years is not sold to the public due National Security) and good soaking the bearings, combined with some compressed air spinning made the turbo running for several seconds after slight push.
It is common knowledge that if PO was shutting off the engine right after flooring it - the oil on turbo bearings will turn into charcoal.

So I haven't had a chance to pull the turbo, but I had some time last night and got a few things done. I ran a contribution test on the AE and it stayed pretty much on zero. I got a misfire cylinder data on all cylinders, and p0046 along with an EGR code and some glow plug codes. Also performed the buzz test but only faintly heard three buzzes and a ton of clicks. On my 7.3 I heard them all, and then one at a time really easy. Any ideas? I'd like to get this all taken care of in one big chunk.

Any ideas? Narrowed the boost down to the turbo. I think I'm going to go ahead and swap it for either the powermax or stage 1 MTW.

Got the powermax installed but having a hard time on getting the y pipe to line up. Taking a break and grabbing some lunch. I found one suggestion to use a ratchet strap but can't figure out what they are talking about. Any ideas?

Heated it up and and I was able to get it on. No leaks and I have a good sounding whistle. Haven't had a chance to take it out yet, but sounds better.
