I'm considering replacing the sump o-rings to see if that resolves an intermittent sticky lifter. Since the pan will be off, are there other things that could get some maintenance refreshing?

As a first step, I'm trying some 20/50 oil this weekend to see if additional viscosity helps.

Chris,
There isn't really much else to do whilst replacing the sump o-rings. In the process of doing so, you're already replacing the oil cooler rectangular o-ring, turbo oil return gasket, sump o-rings, etc..
Good luck, and call me if you have any questions.

..and clean the gunk/crap out the pan.
I'm sure the Seafoam doesn't get anywhere near all of it

Very doubtful a heavy viscosity oil you are going to try willl do anything. Maybe your thinking is that a heavy oil will stay up there in the lifter area after the car sits for awhile. That just masks the problem.

If it was my car, I would try AutoRX first to see if it can clean the gunk around the seals and o rings with the intention of getting oil to lubricate the seals. And clean out the oil passages somewhat.

You will know if it is going to help in the first 500 miles or so. If no change in lifter noise, then proceed to the pan o ring fix.

I Seafoamed this car just before Chris bought it.
I think it's just a time and mileage deal (160+K miles)!

+1 on doing the Auto-Rx cycle. It can actually do great things on sludgy engines, so for a subtle case like this it may be just the ticket. I think then instead of the heavy viscosity, I would go the opposite direction and get some lighter stuff in a very high quality synthetic (that would have the most Group V ester content), and so would do the best job knocking loose deposits. I'd drive it for a while, change it again and see if it improves before I did any surgery on it.

Re: If dropping oil pan, what maintenance could be performed? (Bearclaw)

I've been running a 10/30 Mobil 1 for the past two oil changes and it still seemed to tap every so often. Hot, cold, didn't seem to matter. It has started while sitting at idle after a 40min highway drive and also on an overnight cold start - its not constant, but it does seem to do it at some point during the time the engine is on.

I dropped in 20/50 Mobil 1 today to see how it does. I'll also look for the Auto-Rx.

Thanks guys.

FWIW, the lifters on my NA started making (constant) noise at around 150k.

I picked up some Rislone engine treatment, since the bottle said it "quiets noisy lifters". This stuff worked very well, almost immediately. The noise started up again at around 160k, so I did another treatment with Rislone, and the noise stopped. The car now has 173k, and so far...no more noise.

Good luck, whatever route you choose...

Lucas engine (valve) treatment is also very good
