I'm in the process of fitting my 4.2 inot the TVR 3000S. It had an Olds 215
already but there will still be some problems to solve. Today I made an
adapter to screw onto the engine in place of the oilfilter in order to use a
remote filter. the only direction available to me is forward, as frame,
coolant conduits and damper eliminate most other directions. I can't even
use the two plugs that are used by Rover for a remote cooler. My front cover
has the oil pump driven by the crank, and accepts a distributor.
My questions are three:
1. Am I correct in assuming that the water pump turns counter to the engine?
2. Would someone measure the effective diameters (circumferences might be
easier and more reliable) of the crank and waterpump pulleys. I wanna make
my own pulleys for a serpentine belt. Dayco is sending me the recommended
dimensions for the grooves.I'd like to run the pump at a little slower than
Rover did.
3. My Olds water pump had a small appendage pointing toward the rear of the
engine that connected to a mating nipple on the inlet manifold. The 4.2 pump
has no suich nipple, while the 4.2 manifold has a threaded hole where the
215 manifold had a nipple. What goes into that threaded hole? I use an SD-1
EFI inlet because it's short vertically. It has the same nipple as the 215
manifold. My understanding is that this is a bypass. Do I need it? Does
rover accomplish the same function (I gotta admit, I don't know for sure
what that function is) in some other way?
