Hello,

[pcelite]

Hello,
this is my first post to this majestic forum. My name is Federico, i am from Argentina, and PP usual buyer.

I am rebuilding a magnesium block from a 911 S 2.4 which had the broken studs problem.

In the mean time, i found that the matting surfaces between block and cylinders have some Little damage. Some parts are missing ! no more than 0.1mm. depth, i think. but missing anyway.

Iīd really appreciate your experienced help on this engines, since i don't think it is worth to machine the block for this Little, but i don't want to have oil licks nor inappropriate cylinder guidance or deformations when hot.

Thanks a lot.

PS: also, note the scratches in the connecting rod...i donīt know what happened there (probably made by the man, not the common use or break of engine).

Let's keep the discussion over here

Welcome Federico!

Can you post some pictures or the damage you are seeing? Also, there are copper shims that are supposed go between the case and cylinder. Are these the parts you refer to as missing? do you have Wayne's book on rebuilding?

Best regards,

Michael
