Sadly, no, other than accumulating some more parts.

I was planning to get back to the 914 after club race, but that race didn't end quite as I had hoped. So now I'm working on building a new race car, and the 914 is going to have to stay on the back burner for a while longer.

Hard to believe it's been almost three years since I've worked on this car. All the usual excuses apply -- life, kids, wife, work, racing, etc.

Anyway, it's time to get back on the car. I'd really like to get it drivable by summertime (gotta have a goal, even if it's fantasy....).

I decided to re-start with the guide tubes for the heater control cables. Not sure why, but someone went crazy with a cutoff wheel and removed the tubes, leaving short stubs.

I know the proper, concours-correct fix would be to remove the old guide tubes and braze in new ones. However, the goal is to get the car drivable and enjoyable again, not compete at Pebble Beach, so I'm going to take a simpler approach.

First, I cleaned up the stumps and ground back some of the factory brazing, to expose as must stub as possible. Then, I cut pieces of 3/8" steel brake line and shaped them to fit over the stubs, and then cut pieces of 5/16" steel brake line to replace the missing sections of tube. The brake line is nice because the two sizes are slip fits over each other and the stubs. Plus, I can keep the flared ends of the line to replace the factory flares.

The red things are 10-ga wire. I stripped back about 1/4", flared the copper strands and stuffed them inside the tubes.

Finally, I glued everything in place with JB Weld. After I glued all the pieces, I pulled the wires out, cleaning any extra glue out of the tubes, to make sure the tubes were not blocked by the glue.

The folded-up paper towel is just to hold the tube in place until the glue dries. Don't worry, it won't stay there.

I thought about welding the lines on, but there's no easy way to get the welding torch around the back sides of the stubs, plus it is very tight in there. I also thought about brazing the pieces in, but with my luck I'd set all the stuff left in there on fire. As things are, I can always remove the pieces later on when it's finally time for the full restoration.

Given the history of everything else I've found with the car, I decided to go through the engine before reinstalling it. I got as far as taking the accessories and shrouds off of it, and found plenty of issues.

So, here's what I started with:

As previously mentioned, someone put a fuel pressure regulator where the decel valve was supposed to go (and also left the small vacuum line open to atmosphere).

I found more kinked fuel lines:

All four of the injector fuel lines were like that.

And, once I got the shrouds off, I found this:

Can anyone tell what's wrong with this pic? I'll give you a hint -- there's no thermostat.

Someone on 914World came up with the correct answer -- the flap is underneath the tabs and should be on top. With it set up like that, the cooling flaps are locked open.

I'm not sure if this was planned or if it was a clueless DAPO move. Locking the flaps open without a thermostat makes sense, but there's a spring that also keeps the flaps open. The clue on the cluelessness is the open hole on the side of the engine case. This hole is where the cable pulley mounts, and is a through hole into the engine. When the hole isn't plugged, like when the pulley is bolted on, it makes a big oil leak.

So, this at least explains all the oil under what was supposed to be a freshly-rebuilt engine.

We're back from our vacation trip, and time to get back to work on the car.

First, I took a look at the cylinder head temp sensor, to see what was installed. I couldn't see any numbers, so I thought I'd take it out for a closer look. But, it was very loose. Upon removal, I discovered the hole is stripped. <sigh> The DAPO gifts keep on giving....

So, I have ordered a helicoil kit (10mmx1.0), which should arrive Monday.

But, it turns out the CHT has no numbers on it at all, so I have no idea what it is supposed to be. Does anyone have a good 017 CHT available?

Then, I decided to move on and adjust the valves. They were all on the snug side, so I'm guessing the previous owner never adjusted them after the rebuild. They are set properly now.

Next step was to add in some wiry goodness thanks to @JeffBowlsby on 914World -- new harnesses for the engine.

I installed the generator harness, and will put the others on as the engine progresses. Once I get all harnesses installed, I'll (finally) return the old ones for the core refund, if it isn't too late.

I then moved on to installing a new taco plate and deep sump (tuna can) from 914Werke. First step was to get the old ones off:

I made one change to the bottom plate for the tuna can. I checked the stock bottom plate, and the bolt flange is actually higher than the mounting rim (when installed). So I decided to take about 1/8" off the aluminum bottom plate, to raise it a little bit.

Then, I finished installing everything, including the oil strainer. Because there were now three layers of gaskets, and 9 ft-lb just doesn't seem like much, I used Yamabond on all the gaskets and under the bolt head.

Hopefully no leaks.
