I have a fairly bad rear plate leak (likely oil pump o'ring), along with the front oil pump o'ring small weep. I have decided to just pull the engine vs pulling the front diff and the transmission to repair the leaks.
When I bought this 100 series approx. 4 years ago, I did a fairly extensive reset in the engine bay. I replaced just about every rubber hose (fuel, oil, power steering, trans, water), tees, timing belt & water pump kit, serpentine belt, resealed OEM steering rack. Radiator was replaced by the previous owner, and looks to be in good shape.
My current list is the 2 o'rings, oil pump seal and rear crank seal, and oil pan FIPG. I am trying to keep scope creep to a minimum, but curious if anyone has any "must haves" while I have the engine out. I was considering Doug Thorley headers, but looks like they are NLA, and I don't have any exhaust tick on the current OEM headers, so don't plan on doing them at this time.
I would like to focus on items that really require an engine out to replace. Things like pulling the intake for the starter I would defer to when it shows signs of failing and just do it while the engine is in.
Truck is a 1999 with 350,000 miles.
I have attached the list of parts I replaced in 2022, along with a few other invoices, and a few more orders pasted here:
