I finished up the lower spark plug and EGT/CHT wire routing tonight. The EGT and CHT wires are all differing lengths since they ship the same length but obviously have different distances to travel to get to each cylinder and exhaust pipe. They already come with spade connectors crimped on, so I took the lazy way out and just bundled them up to get them to land in the same general location. Then I trimmed the sensor wires that come from the engine black box and crimped connectors on (I doubled back those wires to give myself some extra length to put a new connector on should I ever need to). For now the connectors are all just hanging out so I can test the connections, but I'll eventually put some wire wrap on them to clean them up. The left and right side are done about the same - I just forgot to get a picture of the finished right side.
I fired up the EFIS to see if I at least had some sensor readings. Success! All CHT readings are the same, which they should be, and all of the EGT readings are also the same. I put a heat gun on one of the cylinder heads and exhaust pipes to make sure the sensors were indeed reading correctly. Everything seems to be working as it should.
The other day I connected the oil breather crankcase vacuum valve to the left exhaust pipe. I removed the Van's rubber hose that was on the oil breather port and replaced it with the much nicer silicone tube that came with the Antisplat kit. This is the bright blue tube in the picture. While it is getting pretty tight behind the engine, the picture actually makes it look tighter than it really is. Everything has room and is not rubbing anywhere.
The tube swings down behind the oil cooler and drops down to the exhaust valve. I split the tube to insert a blow off valve and tube. This is a one way valve that will pop open if the valve at the exhaust ever gets plugged - theoretically saving me from a blown front seal on the engine. I plan to check the exhaust valve at every oil change, so it should not ever get to the point where it can clog up, but better safe than sorry.
I haven't routed the blow off valve tube yet. I think I'll just clamp it to the firewall where the Van's oil breather line was supposed to be clamped, then just let it hang over the exhaust. There shouldn't ever be anything coming out of it unless it's an emergency, and if that's the case I don't really care about the oil that'll be on the belly from it.
