I have the number for #6 (059-103-175-a)

I'm looking for the above #7. I can find it in my part # resource but when I click on it to get the actual number, it doesn't give me any info.
I have a rough idle on the 2.8l B5 and also lose some oil (intermittent loss of 'around' 1/2 quart in 3000k miles, sometime smore sometimes less) which browned my coolant over the course of many miles. My thought is that bad valves are building pressure in the crankcase and causing oil to purge through the head gasket.
These motors are notorious for random oil loss and I'm trying to find a solution. The car has 75k miles on it and this makes sense to me if the gasket is worn and say the valves have been bad for 40k miles.
Anyone have thoughts on this? Tom? Anyone? Oh well... I'm changing them anyhow once I find the part number.
