June 15 - We didn't do much work on the
engine over the past two weeks other than some investigation, ordering
parts, and painting the valve covers.
I talked to TWM about the missing parts and the throttle
linkage problem. Turns out that what I thought were missing parts is
actually where the throttle position sensor is installed. I ordered one
of these. TWM making a special fuel rail part next week to avoid the
throttle linkage interference.
After consulting with Electromotive and TWM, I ordered Bosch 36lb
peak and hold fuel injectors. These are quite a bit more expensive than
I had expected to pay for injectors, but a couple local speed shops both
told me they were the best ones to get.
I also did some investigation on crankcase ventilation and came up
with what I think will be a reasonable
solution.
The Electromotive TEC-II system we're using
incorporates a distributor-less ignition system that uses a crank sensor
to control ignition timing. But since this distributor normally also
drives the oil pump shaft, something is required to do this if a
distributor is not used. A couple companies make what are called
"oil plugs" that are designed to fit the distributor hole when
a normal distributor is not used, but these seem to only be available
for Chevy engines. So, we finally gave up and purchased an MSD 8578
distributor. We're going to send it to MSD to get them to install a
bronze drive gear. Once this is returned, we plan on modifying it to
remove the internal workings to reduce friction.
