318 LA rebuild after losing a valve seat

Well, I thought today was the day.

Pops and another friend came over to help out and act as extra hands and eyes. Good thing they did, because they spotted things that needed correction that I wouldn't have seen on my own. I wanted to flush the radiator prior to filling it with coolant, so my buddy plugged the lower hole while it filled so we could build some pressure to let the water flush any gunk out. The radiator filled and started to piss out water in a steady stream about halfway up on the fins. So that's that. I either need a new radiator or I need to repair this one.

Moving on, they noted that I had no fan shroud. Yes, that's because the fan I bought on eBay was a little larger than the OEM fan, and the shroud didn't fit. Well, this is when I learned that the shroud wasn't just for safety. So now I'm in the market for an OEM fan, which seems to be pretty damn hard to find. If anyone has a part number for a fan for a 318, I'd love to have it.

Slowly but surely, I'll get this car back on the road!
