here's a 964 side
the 911/930/964/993 block are all similar w/ some differences

the 2 passages used by the 911 cooler or 2nd oil filter on a 993 can be seen undrilled here on a 964

the t-stat in the chamber is only present on a 911 or 930 and is not used on a 964 3.6 or 964 3.3t or 993

a 911 or 993 will have these holes drilled

there are 3 top covers, the 2 I mentioned above and a 993 cover, there are small difference in the sensor holes in the covers

to remove the 911 oil cooler and t-stat you need to plug the 2 holes or install a 964t or 993 oil filter console and use the 964 .02 or .20 top cover, then that area functions as on a 964

since you have the holes already drilled the easist thing to do is install an oil filter console and use the .20 top cover, the .20 cover has a deep inner wall that directs flow to the cooler
