And the sense to come to this forum and read carefully.

before I went to all the trouble of dicking around with seal replacement if you're just getting seepage. Another issue is the oil/wt…many synthetics are quite detergent…they can cause leaks if you go from dino to synthetic or if you're running 0W-30 or whatever. You might try a 10W-40 or even 15W-40 (I run 5W-40 Amsoil Euro formula year round, even at -20--30F in ski country) and see if that minimizes the seepage. The mouse milk basically swells seals and can work for quite awhile. A 130K mile 4.2 is also coming up on worn cam chain tensioner guides…if you do choose to pull the cams etc. to do the seals you'll be pulling the tensioners and at that point it's $20 a bank to replace those $%@#$% plastic guides that simply snap onto the tensioners.

If you're running dino oil (non synthetic) I would not recommend the factory
10K miles between oil changes. Nor would I recommend changing to synthetic at 130K miles although the seal swell with various modern synthetics may well work out for you.

BTW, I had a little bit of clatter on startup with 5W-30 synthetic…it went away with 15W-40 Amsoil marine/diesel oil. I think the heavier viscosity helped the leak down in the tensioners on an older 2K4.2A6 with 190K miles on it…my S6 has right around 130K also.
