i had a neighbour ask if i had one on (which i do NOT btw) but he thought the 3" dump and straight through exhaust with no muffler sounded like a BOV due to the whislte noise it makes on spool up and clutching...

do they have a throttle body butterfly? (quite a few modern diesels do)
If they have a throttle body butterfly already, then I'd guess they also already have a BOV or turbo damage would be likely.
If they don't, there's no need for a bov and there's no vacuum signal to pull it open.
In any case, I have two turbo petrol cars and both run plumbed back, stock, bov's. I've driven an off road car with a vented bov and it was a PITA - you got sick of listening to it pretty quick.
I have an old (and I do mean old) turbo kit from an SD33 patrol (these did have a butterfly in the inlet) and it ran an ex OEM Bov.

I'm fairly sure ALL TD motors will have an overboost safety valve, and given that "most" TD motors dont have throttle butterflies, back-surge pressure (often heard as a fluttering type sound) is not an issue. But as said, unless your car has a butterfly somewhere in the intake, dont waste your time/money.

Mates TD42T GU has a BOV on it but its a over boost unit, if it gets to 13+ PSI it pops off, but during gear changes and such it doesn't go off. Diesel's don't work like Petrol engines.
They always have the air intake open, they are always receiving the same air, they will suck it quicker at higher RPM but they have the same air flow. Petrol use throttle bodies to slow the amount of air they are getting or they rev on, diesel use the amount of fuel injected to limit their RPM's

on the GU 3 litre the throttle butterfly is simply to close when you switch the motor off isnt it, to give it a nice smooth shut down?
hence the big vacuum you see on the gauge when you kill it.
you do not need a BOV and it will not function without a pressure differential one side of the throttle body to the other, so with a throttle body permanantly open it will sit there doing nothing...

2H landcruiser is the only one ive seen that has a butterfly. Factory GU turbo diesel is an over boost protection unit.
