This bulletin supersedes and replaces bulletin T-89-42 which should be discarded. It is being revised to include the cylinder head dowel pin part number.
At the start of the 1989 model year Cadillac released a revised intake manifold gasket sealing system. Cadillac recommends conversion to this revised
sealing system whenever possible if repairs being performed on 1988 or prior model engines requires intake manifold removal.
However, before a complete resealing kit can be installed it is essential that the engine be equipped with solid tubular cylinder head to block dowel pins.
(Solid dowel pins were included in both production and service engines during model year 1985 beginning with engine unit number T10L499404. Refer
to Service Bulletin T-86-41.) Because of the dowel pin requirement, service kits for past model year engines are released in two formats:
^
A preferred service complete resealing kit which includes all parts needed to convert past model engines that are equipped with solid cylinder head
dowel pins.
^
An alternate service gasket only kit for servicing engines not equipped with solid cylinder head dowel pins (when service being performed does
not require cylinder head removal).
