Didn't quite get the list address right on the first try, so here it
Not sure what's going on re: your water-in-the-oil-line question, but
as John Logan pointed out the oil pressure sensor screws into the
front-left side of the block, not the timing cover.
But I do have a question for you, or any other list members who cares
to respond. When I installed the bell housing on my rebuilt 5-bolt 289
I was told by a local vintage Mustang parts supplier that new rubber
dust boots for the clutch arm were not available. However,
I see that Sunbeam Specialties lists them in their on-line catalog. I'm
wondering if this is for a 5-bolt motor or a 6-bolt motor, or if perhaps
they are one in the same?
BTW, a good reference book to have on hand for your 289 is Tom
Monroe's HOW TO REBUILD YOUR SMALL-BLOCK FORD.
