[Vwdiesel] aaz, thermostat, bolts, long block engine

[Stephen Kraus]

No travis that helped. I doubt I need to replace the bolts, and I've been
running it at high highway speeds with zero issues. The only thing I need to
replace on my TDI right now is the injectors

 I guess that would be a harder question on the TDI as they LOVE to use TTY
bolts on those things. They could be fine. The thing is that you confirmed
they were stretch bolts with the torque sequence where the older VW engines
I didn't see a TTY sequence for the bolts ever. With metals you can yield
them to a point where they are in plastic deformation. If designed correctly
you can get the correct torque then even if they aren't torqued exactly
right where as a non deforming bolt just a pound or two over/under the
advised amount and if torqued dry or with oil they all affect WAY more. Now
there is a safety factor built into everything so they don't fail if
something isn't up to standards. Re torquing it may or may not have gone
past that. I haven't torn into a TDI yet so I didn't even know about them
being TTY. In the end since it is working you might be safe. But a lot of
the re torqued TTY motor mounts tend to fail thousands of miles after the
timing belt as well so hard to tell. But those bolts have a stretch force
applied to them where as the rod bolts don't have as much. Sorry to get into
the engineering to much. It is really just hard to tell on this one.

Travis maybe you can answer this then, its slightly off topic: I had a 1.9l
TDI AHU block, I put A...
