I am replacing a blown head gasket on my 122 and following a “how to” that has thing pretty well covered including how to “true” the head. It notes to pay attention to the bolt and washers placement. Well, the bolt heads were pretty shot; it took 3 different sized sockets to remove them. There are two lengths currently (2 ¼ “and 2 ½”) and I plan on replacing them with new grade 8 bolts. The shorter bolts had washers with a bevel on them (facing up).
Does anyone know the correct placement of the long and short bolts? Assuming they were in the correct places I will just put them back where they were, but if they were not??? The depth of the bolt holes in the block don’t correspond with the lengths I took out (some long bolts were in shorter holes
) Parts manual shows 4 bolts and 5 studs?? (….and I can’t find any reference to what goes where)?? To further confuse me there are 6 “shorter” holes and 3 deeper in the block.
Logic would say get 6 shorter and 3 longer. Previous owner putting longer bolts in shorter holes may have contributed to the gasket failure if they bottomed out and it didn’t seal uniformly.
And, does anyone know if that unique washer is critical, or will a flat washer, like the others are work? (any reason for the beveled top?)
Thanks for any guidance,
