Attached is a list of gaskets, o-rings and other goodies that I am replacing in 1300 motor. All of the part numbers listed are for an 88 1300. For the most part these will be the same as the 1200. Head gaskets will differ for one. This is not everything that I am replacing, but it is the gaskets & o-rings mainly. Also includes everything in the oil pump galleys. Couple of optional things like the neutral pin on the shifter drum are included.
Water bypass joint in heads needs to be removed to pull heads off. These are a pain to get out intact, but the sometimes can be saved.
A question was asked in another unrelated thread about the list to fix the transmission in a MKI.
This list is assuming heads are removed, case split, & all rubber stuff replaced. Some items are shown as not required or may be reused.
Prices are from partshark.com
I did elect to upgrade the shifter segment components as well.
There is a complete gasket kit available for the MKI's from Athena. It runs around $220 I think. I didn't go this route due to what I saw of the kit, each component was not individually marked. Some of the o-rings have subtle differences as to where they go.
