I'm dropping a 603 in my w123 wagon. At least that's my intention. I've still got to pull the half a 617 out of the bay first and get rid of it. But while I've got the 603 in my garage I want to do as much serious preventative maintenance as I can before it goes into the car.
I've never owned a 603 before (I know, bold move). I've owned a 606 powered car and several 617s. So what work should I do before this thing goes in the engine bay?
It's a 603 from an 87 300TD, and yes it has a #14 head (and no, I don't have any budget to swap a new head). ~140k miles.
So far I'm planning on:
- water pump
- pulley tensioner/belt
- starter (came as a crushed one from donor car)
- valve cover gasket
- hot tanking and maybe painting the manifolds
- injectors
