not sure are are correct no dosh.
the garratt turbo has a life span of around 75,000 miles, and the 2.4
jtd's do seem to suffer turbo failure, sooner or later.
as for boost pressure, well turbodiesels run at a fair good boost and
although the diesel engine runs at a lower speed, the turbo does not.

on the AROC website, turbo failure has been as low as 30,000 miles,

Re: Smokey 156 JTD

It might well be turbo seal problem developing.

Also consider sticky piston rings and/or valvestem seals.
