Inattentive rebuilder. I did that on one of my first engines, you get excited to install the heads and forget which is which. Since both heads have bosses, I just drilled and tapped the other side and moved on.

So I started to take my "rebuilt" motor apart to see what I was dealing with. I am going to continue to split it while I am here and do 2056 with 9550 and my djet.
Here are the pictures of my 2.0 heads, looks like one intake valve and guide have been replaced. How do they look, anything stand out in terms of things to worry about? Is that seam on the inside of the intake part of the casting, seems to be in all the the intakes? There seems to be a few tiny pits around the top of the intake near the guide.

On a related note anyone know of good a machine shop in Canada to look over my GA case etc. as well as the heads?

Last one of intake and some of cylinders. They look ok other than strange scratches. Pistons are marked with 93.97 and a X. Anyone know who made them?

This is a sure sign they were taking short cuts and only did the absolute bare minimum. Those heads should go to a machinist that knows 914 heads and be looked over. When does just 1 valve guide wear out and the others are all good?

Reusing valves is Russian Roulette.. Especially those that have seen damage from rust.
Tick. Tick.... wait for the boom!

Thanks for the advice everyone. They will be getting all new valves and guides. Will work with Mark to get them sorted out. I am glad I decided to tear down the engine. I ordered Jake's video to help me figure out how to put it back together proper.

Hyde, I am in Ottawa.

Can't wait to see what is in the case, its like opening up a present, never know what your going to find. I found this sitting in the case, fell out of the bottom of the oil filler/breather piece.

Very common; that's the cover over the bottom of the PCV valve in the breather tower. It just plugs in, and seems to like to fall out after ~20 years when you remove the oil filler.

Do I need a new clutch disc?
Seriously though, do I need a new pressure plate, is it normal to have a little surface rust on there after sitting for awhile, will it just come off after some normal use, do I need to sand it off, or do I need to scrap it?

When you come down to see me bring it with you, I can check it and/or I have lots of engine spares.

So I finally had time to finish the tear down. Didn't look that bad to me, but what do I know. I didnt find any chips or groves on the case bearing surfaces, but the one thing I did find is that the bearing numbers made an impression on the case surface on the centre main and from what I read in the Tom Wilson book is that means it was hammered in there and the bore will now be oval. Has anyone found that to be the case? I cant find anyone in town to align bore it so was hoping to remain STD. I will have the case measured at a local shop to check but they will have no type 4 knowledge. The crank looked perfect. Whats up with the elephant, that a VW symbol?
