Baz, correct me if I`m wrong, but wasn`t all the european engines high comp no matter what year? Or is that GT imported from the US?

So, it seems that Baz knew something I didn`t. Better research I guess.

easy!
Once you find them it is easy to see. Here is a 1968 head: LH # 68 = 1968 RH # is the engine size 1.9L and the Opel part Number. Of course with the later head's liable to crack you can expect a few earlier heads to have been salvaged and put on later motors over the last 30 years ....

I don't remember when they changed from solid lifters to hydraulics but somewhere around '70 or maybe '71.
I believe '72 was when they changed from the three bearing camshaft to the four bearing camshaft. Harold |

U.S. spec engines were switched to the dished low compression pistons after a mid-'70 build date (from the '70 to the '71 model year), along with the switch from solid lifters and the three-bearing cam to hydraulic lifters and a four bearing cam. The '71 and '73 engine were essentially identical, EXCEPT (and this is BIG) the '73 (but this time after early 1973 build dates) had a 12 bolt head, as in two small extra bolts near the front, into the timing chain case. In North America, the 12 bolt heads were prone to cracking around the exhaust seat, due to a process called "flame hardening" used to make the seats less susceptible to recession caused by unleaded gas. I believe that the Euro engine didn't have that, due to leaded gas being used much later over there. But you very well may have a U.S. spec engine, or even a U.S. GT (quite common to have them re-repatriated to the Continent). FWIW, the Euro 1.9 engines (as mentioned) were also ALL high compression (i.e. flat top pistons) right up to the end of production ('78 IIRC), again because they didn't have to meet the U.S. emission specifications.

Date Stamp
If the block is a '71 it will have a "71" cast on it just like the head - can't remember just exactly where though ..........

'69 Block
My '69 has a block with *19S-0311649* and 22C69 by the starter and unless th PO put Low Comp pistons back in (which i have not checked yet, looking through the spark plug hole the pistons are carboned up) By reading in this and other threads, I have a high comp engine. The Head is a 71. Is there any draw backs in putting the 71 head on a 69 block?
Bo

Early Production ........
Nah! The "33" number is by the date/shift/batch indicator and probably is something to do with the pattern number or foundry number or some other production detail - you have a 1977 year of casting head........ Opel made heads in the hundreds of thousands and they neeeded to know when, where & who made them in case of faults showing up after casting.

The stamp is actually BEHIND the starter. If you lay under the car and use a mirror to see behind the starter, you can see it. It will be just below the 75 that you show in the picture HTH

BTW, any idea what that big H and 75 on the pic means? I don`t get a chance to look behind the starter until later.
