Have any of you guys considered adding a pre-oiler to your 3.0TDI vehicles to pre-charge the engine with oil pressure, thereby tensioning the chains and preventing the startup rattle and associated damage from ever occuring?
Accusump makes some, but there are several brands.
I was thinking that it would be very easy to add one of these with a 12V solenoid hooked into the glow circuit, precharging the engine with oil pressure while the "wait to start" light is on. This also adds some reserve capacity to the oil system.
Chain stretch would always be an issue, but it seems the majority of issues I hear about are due to tensioner bleed-down and damage due to chain slack. If everything is tight, the chance of damage is minimized.
The B6/B7 S4 guys use these accumulators to great effect.
