Valve stem seals and valve guides
Since I bought new valve spring kits for my car, I need to know is it necessary to buy these valve stem seals and these valve stem guides? Or just buy OEM seals and guides?

I'd be careful with the guides - 1.8T parts may not necessarily work in the V8 as it has roller cam followers and longer valves iirc.
Given that the original stem seals are still working in most engines after 20 years I would just use OEM or equivalent for those - Victor Reinz and / or Elring make them I think. They are used in lots of other models so easy enough to get.

I didn't know that about the guides. Good thing I asked about that before ordering them. Do you have the part numbers for the OEM seals and guides?

The guides aren't listed as a separate part but the stem seals are 036109675A.

That's a bummer about the guides.
Thanks for the part number on the seals. Holy crap around $10 for one OEM seal? Is this part number for the intake valves or exhaust valves? Or are these the same for both valves? Also in my search with this part number there are different colors for the seals? Why is that?

Quote:
 Elring can be found for half that. They are the same on inlet and exhaust. They seem to be mostly green, but there do appear to be a few black / brown versions.
