Hey guys,

Recently joined this forum as I started working on a 73 914 2.0. The last time the car ran it was making a bad noise. It hasn't run in about 15 years. I pulled the motor and started taking everything apart. I have to say that the flat head screws that hold most of the engine cooling sheet metal on are a damn pain in the ass. The flywheel turned freely and nothing seemed seized. The motor is pretty high mileage. Somewhere around 200k. The odometer stopped working around 140k miles. So enough talking, here are some pictures of where I am with the project right now.

(IMG:http://www.914world.com/bbs2/uploads_offsite/i1292.photobucket.com-17807-1409264677.5.jpg)
And here is the car it came out of. It's always been a California car so the rust is minimal. Only a couple places of cosmetic rust.
(IMG:http://www.914world.com/bbs2/uploads_offsite/i1292.photobucket.com-17807-1409264678.6.jpg)
I'm in the process of pulling the cylinders and pistons and then I'm gonna decide whether I want to split the case or not.

I don't really want to make this car into a race car or anything. Just get it running and driving well. That being said, I don't want to dump $1000 into new pistons and cylinders. Anyone have any good options? Cylinder honing?

(IMG:style_emoticons/default/welcome.png) San Dimas. That was the first place that I got lost in CA. Ended up in LA and a traffic jam at 9:00 pm. (IMG:style_emoticons/default/chair.gif)

Nice car you have there and 15 years is too long to keep in hanging. You should finish the engine sir and drive the car soon.

That's my intention. Got all the cylinders off and two of the pistons but I need to get it off the engine stand before I can get the other two pistons out. I also need to get my hands on an impact wrench to remove the flywheel... (IMG:style_emoticons/default/rolleyes.gif)

Here's where I stand now.

Anyone have any tips on removing the massive carbon build up on and around the valves? I tried degreaser and a toothbrush but it's obviously going to take something a bit more aggressive to get the job done.

Thought I would give an update to this thread to update my progress. Got everything apart a while ago. Had the crank polished, cam reground and heads rebuild with new guides and valves. New bearings all throughout. Reassembled and now have a complete long block. Ready to get off the bench and mount the trans back up.

a photo and a little time lapse of installing push rod tubes and valve adjustment.

I'm not sure what caused the two marks on the intake valve. But all the valves were replaced when the heads were rebuilt anyway and I checked clearances upon reassembly to make sure there will be no piston to valve contact.

Brother's VW in Ontario, CA did all the machine work. Nice guys. Very knowledgeable on all things Volkswagen and reasonable prices. I would recommend them.

Couple more questions as I come nearing the end of the rebuild (hopefully haha). I tried hard to mark all the connections so I would know where everything would need to go back come time for reassembly. But, now that I have the motor back in, I have noticed that I missed a couple. I'm hoping you guys can help me out a bit.

Took some pics to show you what I'm looking at.

First one is a white wire coming out of the ECU harness just past the injector plugs for cylinders 3 and 4. I think it connects with the white wire with inline fuse in the next photo but not 100% sure.
(IMG:http://www.914world.com/bbs2/uploads_offsite/i1292.photobucket.com-17807-1413574398.1.jpg)

This photo is of the harness that connects to the board on the driver side of the car and connects to the starter motor (sorry, not sure of the proper name). It has the white wire with inline fuse mentioned above. But there is also a green wire with a red or pink strip that I'm not too sure on.
(IMG:http://www.914world.com/bbs2/uploads_offsite/i1292.photobucket.com-17807-1413574398.2.jpg)

Here is the green wire that comes off of the distributor.
(IMG:http://www.914world.com/bbs2/uploads_offsite/i1292.photobucket.com-17807-1413574399.3.jpg)

And here are, what I'm pretty sure are ground wires. Not too sure where they are supposed to hook up. They are pretty close to the case nut/bolt at the top of the flywheel so I'm thinking the ring might go on that bolt.
(IMG:http://www.914world.com/bbs2/uploads_offsite/i1292.photobucket.com-17807-1413574399.4.jpg)

Lastly, There is the cylinder temp sensor. I'm not sure where that needs to plug in and also, what I think is the oil temp sensor, that is a red wire that comes out of the bottom of the motor near the oil drain plug.

Any help you guys can give is much appreciated!

The "fuse holder" is just a connector. The male part is usually held inside the plastic box, and the female part of the connector gets pushed in the other end.

The wire in the first pic is quite likely for the head temp sensor, the one that lives near the #3 spark plug.

The green/red wire goes to the oil pressure switch near the distributor.

That green wire off the distributor.... Could be the wire from the points/condenser to the (-) side of the coil?

The ring terminal with lots of wires is indeed the common ground point for most of the fuel injection. The ring goes over the case bolt on top of the motor closest to the transmission end.

Thanks Dave,

Been looking at wiring diagrams for the last hour and was thinking the same for all of those. Thanks for confirming for me!
