'69 Bug starting to work on the engine

[Swill]

Looking for some expertise from the group. I have a '69 bug which belonged to a friend of mine. Her husband bought it for her when he was stationed overseas in late '68, and it was shipped from Germany to the US. While I am officially the second owner, the car has been through several teenagers.

I've pulled the engine because the compression was low (50-60) in cylinders 1 & 2, and it was leaking oil like a sieve. I am starting to take the peripheral equipment off of the engine and have a few questions.

The chart I found here http://www.thesamba.com/vw/archives/info/bugchassisdating.php makes me believe that the engine in the car is a 1300 manufactured in Aug of 1969. This leads me to believe that this is not the original engine.

I noticed that the pulley on the generator does not line up with the pulley on the crankshaft.

and that the plate that the forward end of the generator attaches to was indented

Is the generator the wrong one, or is the piece that connects the generator to the shroud wrong? Or is there some other reason that the pulleys don't line up?

There is a vacuum port on the left intake manifold. I've read that this might be for smog control for later model engines? It had a short vacuum line attached to it with a plug when I pulled the engine.

These are cooling vanes on the right side of the shroud. I have determined that the arm on the lower right side in this picture should connect to a thermostat, but what you see is what was there when I pulled the shroud. The arms were wired together, and there was nothing with which to connect to the thermostat. I believe that the missing part that connects these arms together would also connect the left and right set of vanes, but that piece is missing also.

Finally, the SAMBA gallery rotates my pictures for some reason. Any advice?

Thanks in advance.

Cheers, Swill

Odds are against it being a 1300 since it has dual port heads.Most likely a 1300 case updated to 1600 at one point or another.To realign the generator/ crank pulley issue loosen the generator clamp and the 6mm bolt on each side of the fan housing at the bottom by the rear sparkplugs and gently pull the fan housing forward till the gen pulley aligns with the crank pulley.

The link bar is missing from you thermostat flaps its not uncommon,most time all the thermostat stuff is ripped out.seach the classifieds here if you want the parts.

Thanks, johnnypan. She did say that the engine had been in and out several times. I am hoping that the engine is worth rebuilding, but I guess I will find that out as I tear into it...

Crankshaft endplay is a good indicator of engine wear...push and pull on the crank pulley and see how much wear...if its a 1/4" most likely it will need lineboring.

Found out the F1 indicates that it is, indeed, a 1300 replacement case. It has been upgraded to dual port, and the intake manifolds for the dual port come with that vacuum port on the left side.

I am thinking that the reason the cylinders on the right side failed was because the thermostat flaps failed shut. That could explain the rather quick transition from running fairly well to hardly running. I have heard two different stories about the flaps; one side says that they are necessary for proper operation and the other says rip 'em out or tack weld them open. Since the thermostat and connecting linkage is missing I may just remove them for the time being and see how things go.

Picked up a nice, inexpensive engine stand on Craig's list, now I need to get the VW adaptor for it so I can start tearing into the engine...

Just from looking at it I would say that the generator backing plate being dented in is what is causing your pulley misalignment. I would replace that backing plate.

That's what I am thinking. The more I look at the car in general and the engine in particular I come to the conclusion that the previous owner used whatever parts the could get their hands on...
