Plugging the vanos holes in the oil filter housing

[lolcantturn]

Hi I have a vanos oil filter housing but I'm non vanos, with what do I plug the holes with? The smaller one (closest to the camera) is a regular M12 bolt, I just used a front caliper bolt that was M12, but the bigger one (furthest away) is not M12, it appears to be bigger and lowes just quite doesn't have that size in stock. What should I use? Any OEM type bolt that will work for this?

Are u back in Philly? There is a sears hardware store on city line, they have every size of metric hardware you can think of in most thread pitches, bring the housing in and check it

one is the oil pressure port for the senor(left) to plug the vanos side use a bolt with same threads and a aluminum washer like the drain plug uses

The non-vanos has a plug from the factory, look it up on real oem.
