That's good to know @mb911 , thanks!

When I dropped the motor I found that there was MUCH more oil in the sump than what came out of the line/tank. Maybe a side effect of all the engine cranking I did? Does anyone care to speculate?

I surfaced the intermediate shaft cap and reinstalled the engine, then got it back up and in. The car is back in one piece and ready for tomorrow. Although now I'm really worried about oil pump seals. I was very careful when getting the case halves together, but you know how the mind works when nearing the end of an engine build and finding something you didn't expect...

I've had the appointment set for about a month. When I made it I wasn't sure if I would be ready, but it was a date that was available. Heck, I wasn't even sure if I would have them do it or if I would end up doing it all myself. Right now though, I'm pretty burned out on working on it and I'm glad I have it.

So, lets hope the next project update I post here is me driving the car.

You will have a good amount of oil in the case until its running. Also did you rebuild your pump or replace or just clean. It's really hard to get those seals out of place so I think you will be just fine. The biggest issue I see on these conversions is lack of understanding of the oil flow path and clocking the oil filter console correctly which is just sometimes over looked. I suspect you are all good to go so just be patient.

Yes, a 4-rib oil pump was purchased and rebuilt by Henry at Supertech. I believe a 4 rib is the minimum requirement for the oil bypass case mod to work.

Thanks again for your input!

Same guy that did mine. Works great in my car with very little drain back to the case and very little smoke on start up.

The engine will always fill with oil from the tank when sitting. The oil pump has clearances and the oil will go right thru. When the oil level in tank is higher than the engine it drains out of tank until level. The scavenge side of the pump (which returns oil to tank) is much larger than pressure side. When the engine is running there is more oil volume being pumped to the tank so the tank is full. This is why you have to check the oil level with engine running.
On the GT3's the scavenge side of the pump is large enough that it pulls a vacuum in the engine. GT3's have valving to maintain this vaccuum which reduces windage. I believe on some GT3's the rear main seal is installed the reverse of normal to aid in vacuum retention.
On the 2.4 in my -6 conversion I do not get enough pressure for the gauge or oil light to go out when just cranking. Once started light and gauge move off zero.

Thanks guys, from talking me back from the proverbial ledge. I can't wait for tomorrow!

Now, do I hitch a ride with the tow driver down to the shop, Uber down, or take my daily and go back for it at a later date? Decisions decisions.

We have the car at the shop now, I'll be doing live updates throughout the day on my Instagram

@glen_in_the_garage

So far, we weren't getting power at the fuel pump. My best guess is the wiring that I spliced in, it's right at the snorkel and buried under the firewall engine mount. For now we're jumping it and I'll dig into that at home.

Then the passenger side carb was a geyser, maybe a stuck float? Currently pulling it apart to see.


We did some more cranking earlier on, before fuel, and I did see the pressure gauge move a bit, so that's nice.

It's running!

Currently doing the 20 min run and the guys are monitoring it closely.

The four rib is the ultimate.
On early cars the oil light can be on at idle when at elevated temp (engine & ambient)
and not be a big cause for concern.
Cranking speed with plugs out will usually turn OP light off.
Can take some time and cranking sound changes noticably when OP comes up.
Great milestone Glen! Congratulations !

Well it's running and I drove it home. A few things I need to address:

-brake light switch at pedal is stuck on
-oil pressure gauge worked when initially cranking this morning, currently not. Need to dig back into that
-need a real alignment, I got it pretty close but it needs some love
-fuel pump power is cut somewhere, probably right where I spliced the wire in all those years ago, which is basically where the snorkel is buried under the mount. We got it going with a wire routed outside of the car and a toggle to turn it off/on.

It sounds good, but will be better with Ben's muffler in place.

And I need to figure out why the tach isn't going.

I figured out what the issue was with the fuel pump wiring, but a bit late.


When I originally moved the pump to the front I followed this guide

http://www.914world.com/specs/SirAndyCarbFuelPumpRelay.php

One item that I failed to remember when putting this all back together was the wire added to ground to replace the FI brain. So we couldn't get the fuel pump to go and I didn't knoiw why. We rigged it to get me home.

Last night I was digging into it, and I was following a guide that tested the relay boar traces, and everything seemed exactly right but I still wasn't getting power through the fuel pump relay (tested the relay, swapped known-good relays, had +12 at pin 30 on the relay, etc)

Eventually, I pulled +12 switched power from the 4-pin FI plug, ran it to the front with an inline 10A fuse near the fuel pump, and was hoping that would be acceptable.


Lo and behold today I re-discover the walkthrough that SirAndy posted, the link above, and it all came flooding back from all thos eyears ago. To my amusement, the solution I had found was also described in his post as a "last resort"

(IMG:http://www.914world.com/specs/SirAndyCarbFuelPumpRelay_files/RelayBoard.JPG)

I'm a bit upset that my wiring isn't as original and clean as it could be, but I'm glad I have a working solutuion at least and I know what the problem was.
