> Was it the MY02 or MY03 that brought in the metal dowels?
***Late 03my from memory, also the heads are different hence the
reasonson for the introduction of steel dowels.
(basically locators thats all)
I could presume that the steel dowels were introduced to the later
models because of an increase in torque & power..!
>How frequent do these things fail and are there any trends?
***Not often & no trends, theres normally underlying factors that
contribute to head failure, overheating being a major one of them.
Also this in relation to retrofitting steel dowels. This can not and should not be done for every TD5.
