Need help with a '68 912 case

[otif]

I bought a pile of parts from a retiring mechanic, and included was this case. I searched it up and the stamping on it (616/39) revealed that it's a 1968, with emission control from July '67 on. The serial number is 113855. I read somewhere that the serial number on these cases are usually incorrect, or irrelevant. Didn't make much sense to me, but is that so?

Any input, especially with regards to the value would be greatly appreciated.

There is a date circle stamp on the 'inside' of the case (I believe right side) that can be seen if the third piece is removed. There is also a date circle stamp on the inside of the third piece.

What the case is worth is another story: I purchased a NOS case without third piece a couple of years ago for $1000 (IIRC, stamped '70' as in 1970). I got a motor with a 68 parts car that had run a twisted SPG roller crank and the case was cracked around the oil sump under bearing #1 around both sides: scrap metal. These cases can be reclaimed but the cost can be prohibitive.

My suggestion is to take the case to a 616 professional: get it cleaned, inspected and measured. If its in good shape, standard bore and clean, Its probably worth $600-800 to the right buyer. Or you could sell it 'as is/no knowledge' for a couple hundred bucks.

What's the serial # on the third piece below the generator stand mount?

1968 US/CDN Emission control serial number would be 128xxxx.

Found a couple of photos for you. I was wrong: date circle appears on both halves of the case.

Thanks, Peter! I'll look at it again tomorrow, and post my findings.

Pm Dave Pateman. He keeps a registry of serial numbers. He could tell you within 100 cars what chassis this case was delivered in.
This case is worth more to the owner of the original car than the usual Joe on the street. Might want to get it up in the 912 registry and start hunting for its original chassis.

You are somewhat correct in that the case build number is not important. Porsche did not keep records of which case was mated with which third piece. When people look for "matching number" they generally will only look at the engine number on the third piece. Small chance they would also check to see if it is has the correct case type. Highly unlikely anyone would check the case build number.

The case number should be 1283855 for the 616/39, not 113855 for a 68 912

It is a 7 digit number. 1= 90 hp, 4 cyc, 2= emission control (EECS), 8= 1968, 3855= Sequential number.

If the engine number is 113855 on the third member. Then the third member is maybe for a 356. the 65-67 912's only have a 6 digit engine number. Starting with 740000. The 68 stared with 1280000. and 69 stared with 4093001 both were 7 digits numbers.

Your build number of 113855 looks to be correct when compared to other 616/39 cases. However it does look like the 616/39 has been restamped. Might check the pairing numbers to make sure the case halves match. Jaems and Peter are correct in that the number on the third piece should start with a 128xxxx. it is this number that will determine the value. Should you find someone searching for this case, it might be worth more than $600-$800.

Hi guys,

Thanks for all the input. I was at the sho all day, notmore than 10 feet from the case, but didn't get a chance to even look at it. The serial number on the third piece under the generator mount, that Peter mentioned. Is that found on top of the "Made in Germany" stamp? If it is, there is nothing there. Doesn't look shaved either.

Then it is a replacement engine. They generally did not put a Engine # on a factory replacement case.

Also the Industrial engines used a 110000 sequential numbers. I had forgot about them.
