I have a 97 K2500 suburban 4x4 that, I think, has an oil leak from around the oil filter adapter. Does anyone know the oring part numbers or sizes that I will need to replace? All I've been able to find on the forums are part numbers for earlier models. I have access to Viton orings at my job, so sizes would be great! Thanks...
 
Here is from my notes:

O-Ring for Filter adapter:
GM part number 12559583 smallest o ring is standard o-ring 115
GM part number 12559584 medium o ring is standard o-ring 215
GM part number 12559095 largest o ring is standard o-ring 235
Can be purchased at bearing wholesaler

GM part numbers for O rings and copper gasket for a 94-95 - 90º oil filter adapter
Big O ring 12559095
2 small O rings 23500360
Copper gasket 23500358

I have not verified it. I suspect the 1st set are for 97 truck and 2nd set for 94-95.
 
Thanks. I'm gonna give it a shot on the next oil change. Although, I am thinking about just adding a filter relocation kit while I'm at it. Any opinions on who sells the best kit?
 
As far as I Know the 90* is eliminated when going the remote route.
 
Here is a piccy of the Orings I used on the 95 DaHoooley build.

Part numbers too

There was a GM upgrade on the pre 95,s. I did mine while it was apart. There was a service bulletin on it. Some seals were eliminated and different, fewer were substituted.
