|
Does anyone know what the numbered white stamp marks on the front of the fan shroud mean???? I have a 158 numerical stamp on the front / facing side of the fan shroud and could not find its meaning....
I also searched other Ghia's for sale with their engine bay open and found other fan shrouds marked the same...I did find one marked EA 364 which was a late '74
Could it perhaps be an inspector's stamp???? Not sure....

That is an M-code telling specs. of the engine. Excaust control system maybe? |

So I looked up the M-Code on the Samba site for Ghia's and there was no 158 on the chart....for Type I's however, 158 represents cloth upholstery.... |

I noticed that too but check out M code 157 for Ghias, I bet it's something very similar to that.
One entry from 157
44 bhp engine - 53 SAE with exhaust control system, with activated carbon container for absorbing fuel vapor
from Chassis No. 148 000 001 up to 149 1200 000 _________________ How to Post Photos

"I O"marking is the German equivalent of "OK"...
The 158 has me baffled..the engine assembler certainly didn't care what upholstery the car had.. Across all tech archives ( type 1 through 14) is 157.
I even dug out an old Type 181 book I have and it's the same for all..Emission control system(S)...carbon canister etc.
Maybe o'l Hanz had a few too many schnapps the night before?
These numbers can usually be found on the back (front) of the shroud as well..
Can you get a peek behind? maybe with a mirror? What engine number is this one?
Edit..also this stenciled number should have the number 14 ahead of it if it were original to the Ghia _________________ '68 Campmobile-Pedro

I did find the number 158 on the back side as well....my engine number is: AE595340
The other making was a "LO" on the fan not "IO"...part of the lettering was blocked by the transfer tube....
I sure would like to know what these stampings mean...it's starting to drive me crazy not knowing... |

Strange for sure..Your engine case number aligns with post August 1972.. meaning a 1973 model..but this is for type1 beetle..according to archived info here, the Ghia engines had the letter 0 after the AE.. and that rolls into the 1973 model..( I have only in my life seen one numbers
matching engine to a Ghia but that was a late '60s model H0 number) so I've never seen a "AE 0 xxxxxx" case...
I did mention earlier that I've seen Ghia shrouds with the 14 157 on it..
Maybe it's possible that a previous owner painted the shroud after an engine swap and picked those numbers and letters to paint back on for posterity..albeit with no real meaning? ( that "LO" instead of "IO" makes no sense either) _________________ '68 Campmobile-Pedro

As pointed out by Everett, these numbers were equipment designations used by the factory to make sure that certain types of engines made their way into the correct vehicles. _________________ Everybody born before 1975 has a story, good, bad, or indifferent, about a VW.

Thanks to all who responded....I think I'll put this to rest....the engine is original, not a swap out....and the vehicle is registered as a 72'....I do want to keep the vehicle as original as possible and that is where this quest for knowledge all started |

When I researched these for my 71 beetle vert, I found that they were marked with the following markings
1. Type - for Typ another than beetle - I.e engines going into KG were marked 14, into beetle verts were marked 15. Probably to distinguish those that were designated to be sent to Karmann.
2. Engine size - mine was marked 1.6. Not sure if all engines were marked or just the S (1600) code engines to differentiate from the similar looking 1300.
3. M-codes related to engine. Mine was marked m-240. I’ve seen others marked with US emission related codes.
4. I.O. Marking. This OK symbol seemed freehand with more variation (may explain why the I looks like an L for OP) _________________ 1971 1302LS Convertible (RHD) owned since '74
