simple things first: secondary fuel filer change+test drive if no change: test drive from separate tank let's "turbo red glow" theorize later .

If timing is the problem, could be your timing device is not doing it's job. My Xenon timing light/ RIV Adapter will easily tell you if that is the problem or not.

Plugged exhaust? I've seen it happen, worth investigating. Look over your exhaust manifold and turbo piping carefully to see if there is a port or plug you can temporarily open up, to avoid the pain of pulling the exhaust pipe off the turbo.
Low exhaust flow would account for both the glowing red turbo and the loss of power (too much back-pressure).

This happened to me twice when on a trip while on the interstate. Both times were caused by clogged filters. I changed both filters so can't determine whether primary or secondary was at fault. Two sets now reside in the trunk with tools. They get changed prior to aroax trip.

Oh cool, thanks for the offer. I'm very close.
I had thought of an exhaust restriction but can't see how that's possible with no cat. It seems like there would have to be some extreme condition to cause something like that, or ultra high mileage maybe. Im under 200K. Anyway I didn't see any obvious way to get a peak into the manifold area yet. I was only able to replace the filters today and there was no difference. I will try the bypass tomr and hope that solves the mystery... getting nervous! |

Whatever happened with that? Is it available as a tool rental? DIY plans?

If you don't have a fueling problem, and you don't have an air restriction (plugged air filter) problem or exhaust restriction problem, then you may have a very non-typical turbo failure? I think if the turbine locked up, it would restrict intake and exhaust, but I'm not sure the effect would be so dramatic.
I seriously doubt this could be a timing problem or an internal engine problem. If the injection pump timing hasn't been touched and the adjusting nuts/bolts are still tight, that is probably not your problem.

Restricted fuel filters won't make the turbo glow. That's a typical sign of retarded timing, especially if not accompanied by heavy smoke.

how dark was it when the glowing turbo was noticed? how bright was the glow?

It's a finished project, verified and working great. I have not put it into the rental section but if you or anyone is interested in renting it, PM or email me for details. Be forewarned it will have a hefty deposit. Sorry no DIY plans.

What does the exhaust smell like when it is running? If it is very rich, it could be retarded timing and that can make a turbo get too hot.

EGR valve failure? Feeding the exhaust directly back into the intake certainly will rob a lot of power (been there done that with an EGR valve failed in full open position). However, the power loss was accompanied by lots of smoke (unburned fuel).
