Owners of Turbo cars, do you strictly follow the 30 second "cooldown" ?"

The 1.8T is known to have turbos, exhaust manifolds and heads cracking from overheating (especially the more powerful versions) and letting it cooldown is a strong recommendation.
hmm.... I posted that I haven't paid attention to cool down with the Transit's turbos since I assume I didn't have to with newer tech. However... there are reports of exhaust manifold bolts breaking on the Transit 3.5 EcoBoost and those are a bear to replace. I haven't seen anyone mention it on the forums but maybe a cool down would help.

@kingt I did with my RX-7, way back when, even though it wasn't turbo. But with my E60 (only turbo I've ever owned), the fans would keep running after shutdown anyway, and I figured, what the hell, everything else is gonna break first.

If it makes any difference.
All of the newer 4-stoke diesel generators on the vessels now go into a cool down mode [ours is 3min] after disconnecting from the electrical switchboard when stopping remotely, regardless of runtime or load. This goes for both main and emergency generators. We have the option to override but rarely do.
The main engines have a dedicated lower pressure oil circulating pump that we run at least 15min before start and 30min after stopping.
Metallurgy with regards to heat is actually very interesting to study. We mess around with close tolerances for shafts and bearings as well as seized fasteners. It’s amazing what a hot torch, bearing heater or CO2 extinguisher/freezer can do with regards to metal expanding and contracting. It can be as effective or better than a puller or hydraulic press sometimes.
