Cheap 86.5 auto on CL $2500
#17
It sounds like "TBF" means Timing Belt Failure to some and Thrust Bearing Failure to others in this thread.
86.5's don't usually experience ThBF.
If it were closer to me it would be on my trailer now. The most likely no start conditions for this car are simple and cheap, but there certainly is some risk.

Exactly, the Onion was running and I paid $1,900. and the only good sub assembly so far that did not require a rebuild (only a filter /fluid service) was the Auto Trans.
Engine, Rad, Rack so far, but they are now done and I won't need to go back there.
The thing that stopped me from parting it out was the condition of the metal parts under the hood and under the car, no oxidation at all, all the original plating was intact. It was a California car.
Still working through wiring issues, the TT will need to be rebuilt and axle boots replaced.
Guys these are 25 year old cars! Unless someone really has taken care of them they will need Part$ and time consuming work to be dependable much less presentable.
Its only in the satisfaction of doing it and the results that makes it worth it, for me anyway.
Last night I had one of my son's friends (22 yrs old) drive the Onion, and when it was back in the garage he said I now know why you like these cars Mr K and all the work you did shows in how it drives and runs. He had been in my Blue '85 with N2O but never drove a 928.
I bought the Onion in July of '11 it's now Dec of '12 and just may of resolved the idle issue Tuesday night
I'd offer the guy a $1,000 for it as a parts car at least you won't get hurt too bad

lol maybe. Actually as it turns out the 80 only needed a few relays to fir right up. Runs great too. all 55 hp of it. Im sure it will be a real genuine "Porsche" feeling when I'm getting passed by scooters on the road.

Didn't TBF become more of an issue with '85 and up?
It’s not always obvious what is meant by TBF. I personally always mean Thrust Bearing Failure when I say TBF.
I can see how TBF could represent Timing Belt Failure and is probably a more common definition than Thrust Bearing Failure. One could argue whether that belt is a “timing” belt or a “cam” belt. Porsche refers to it as a “toothed” belt. TBF could even mean “Toothed Belt Failure”.
To many mechanics, thrust bearing failure is not a common term as most have never seen it or even heard of it. For the 928 mechanic though, if not already, it should be common knowledge.
The toothed belt does affect both valve and ignition timing but its primary purpose is to “drive the camshafts”. So, from here on, let’s refer to the toothed belt as a “cam” belt and “cam belt failure” as CBF.
Yep, that’s my story and I’m stickin’ to it!
TBF = Thrust Bearing Failure
CBF = Cam Belt Failure
