Don’t I feel stupid!
Well the pump was 180 off. So when I rotated the sprocket 180 I noticed another notch.. well it just so happens that the sprocket that I was using had a near perfect chip on the edge what looks to be nearly 180 from the factory notch. So when I assemble these I always mark the ‘0’ mark and the notch on the IP sprocket with a silver paint pen to make it easy to spot. Well I marked the non-factory chip/notch in the sprocket. I’m so surprised I didn’t notice it before! Well I threw that sprocket in my scrap pile as it cost me many many hours :-(
I’m surprised that the engine was able to start that easy 180 off. The engine took about 4 seconds of crank time to start, and it actually idled smooth! I have never had one start this easy 180 off or idle that well. Timing is now correct and it’s running like it should! :-) Thanks ngoma!

Funny how when you are "sure" it's not one thing, you'll try a million other less likely things first before coming back to what should have been obvious all along. I hate getting bitten by that situation. One time I had one go 180 off like this, but due in that case to a mistake on my part, and I was so sure I couldn't have timed it 180 out that I think I started looking at glow plugs, fuel prime, etc, even though it was an engine that had just been running no problem before I took the belts off it. Sounds like the same kind of outcome here. But in your case even more crazy because that trick sprocket would have made it look exactly right even when it wasn't, what a trip! At least you know it must have great compression if it started and ran that well with the timing 180 off. So what else is left on the swap now, must be pretty near done?

I had to share the sprocket, the correct one is on the right.
I’m pretty sure the one on the left was modified because someone had built a pump with the cam plate 180 off., now I’m unsure if my leaking pump that I pulled is 180 off or not. I’m assuming it is as I usually keep the sprocket with the pump when I remove them from the engine. If you look closely you can see the factory notch has a chip in it and the 180 notch looks factory, but it’s actually cut deeper now that you compare a factory sprocket with it side by side. Crazy! I don’t know how many needless hours I spent tracking non-issues because of that sprocket!

I wonder if you can visually verify the pin/key slot mismatch when you have the cover off for the reseal? Might be too buried.

Never going to get back the time that part stole from you, I'd be pretty mad at the thing. However, if it makes it any better, thinking about it now, I bet whoever put that notch in that sprocket suffered for a long time too before they figured out they built the pump itself 180 off. There's a long chain of misery attached to that sprocket now, everyone will be better off when it is melted down for scrap.

First drive oil powered!
I put 50 miles on it, all went well, yay! No leaks discovered, engine runs nice like it should, very quite too when using the D24 exhaust, it might be too restrictive though. Rear end gearing is low, I discovered that this car was originally an automatic ( ugly hole drilled in firewall for clutch cable) so it probably has 3.91 gears in it which I think are too low for the m46 OD of .82. But overall it drives decent and has decent power (it’s been awhile since I have driven a non modded out d24t).

Didn't the factory M46 get 3:54 or 3:31 final drive ratio?
What kind of hose did you use for the VC breather?
