Maybe once a couple of these are sold. Although... she did say "no more than 10." It may have been said sarcastically accompanied by an eye roll. I may have had a handprint her exact size on my back following said statement. I have fortunately forgotten that part and will concentrate on the number 10 instead. Seems like a solid plan! Right?

Back with the rebuilt transmission! She was burnt up. Filter clogged with material. Wrong filter. Bushings fried. Nothing left of friction material on the places its supposed to be. Had him install a stage 1 shift kit. The instruction say kickdown should never happen unless at wide open throttle. Claimed premature kickdown is primary cause of wear in a C4. Said to bend kickdown linkage so it only happens at full throttle. Sounds excessive for a daily driver. Any Input from you guys?

Nope, can't help with that one. WAY back when, when I had an auto car, I installed a "Shift Improvement" kit or something like that. Seems I pulled the kickdown linkage and would just downshift manually. That lasted a couple years before I pulled that car apart and swapped a 4 speed into it.

I usually don't run a kickdown on my C4 at all. I slap the shifter back to 2nd when I need to pass and back to 3rd when I'm done.

Of course, I have a Hurst V-Matic shifter in the car.

Finished up cleaning and prep work. New p/s rack, pump and lines. Changed kick down lever on trans to a shorter one as the rod/lever were hitting the header. Swapped timing cover to a front sump dipstick and mechanical fuel pump. About to reinstall the cleaned up engine and rebuilt trans.

Since I replaced the timing cover my last step was to change the oil. It's full of metal. The magnetic drain plug had 1/4 " of shavings. The filter is full of metal flakes and shavings. There was no metal when I started with this engine. I did replace the oil pump and dizzy. Both new. It drove maybe 2 miles. I pulled dizzy and the gear looks fine. This gear was on the old dizzy that came installed on this engine. I was pissed and quit for the day. I am hoping the new oil pump is bad. Otherwise I will need to rebuild this engine and that's gonna take a while.

This oil pan was cleaned and painted before installing a couple weeks ago. A new oil pump, pickup tube and drive shaft were used. Yesterday I pulled the oil pan. Found grey oiley film on oil pickup tube. A fair amount of metal sludge and several what can best be described as small bb's of metal in the pan. The oil dripping off cylinder walls is clean though. No metal. The oil in the heads shows no metal. Yet the little bit of oil in the pan is full of metal. Pulled oil pump apart, found score marks but no missing metal. Pulled one rod cap and bearing has some wear but nothing concerning. The engine and trans assembly is hanging on the hoist so I didn't want to stick my head underneath to see cam gear. I will attempt that later today when I have someone available to call 911 if things go south. At this point I ass-u-me the cam gear is wiped out or the new dizzy is at fault. I just cannot locate where the metal came from.

Neither gear looks wiped out but there is metal all over the cam just behind the gear. I guess the gear wasn't meshing just right and I did not run the engine long enough to destroy the gears yet. Should have ordered a new gear and used the duraspark dizzy. The points dizzy looks fine. It does have a lot of upward play. Maybe bad bushing? Idk.

Can try a new dizzy and keep fingers crossed but there is metal on the first cam lobe. Since dizzy gear does not look bad the cam gear must be worn and I just cannot tell without teardown. I don't want to put a dizzy in and destroy the engine. My financing is dried up until after christmas. Sooo......

I have what is supposed to be a non roller engine with a new crank and cam. I am leaning towards trowing it together and seeing what happens.
