There isn't much that will stop me from fitting a new, clean oil filter, very inexpensive insurance compared to bearings, pistons and rings, cams, lifters, etc.

I was asking about changing the lifters when doing the intake gaskets.

And, very simply that I was advising you to change the oil filter when doing that, and other engine oil related issues.

Oh, I thought you misread lifter as filter.

Do you mean in case one is sticking or because of wear?

Since you're in there, I'd pull the lifters one at a time and look at the bottom of them to check they are still convex. If you find a flat or concave one then you're getting close to a cam failure. If the bottom of one or more looks questionable then the chances of replacement lifters working doesn't have a high chance of success. You can also take a look at the pushrods and rockers for wear at the same time.

Either... they're old, and if I'm already there I thought it might not be a bad idea to replace them. I thought if I'm having one stick now, maybe they become more prone to that?

They're hydraulic roller lifters (Gen VI).

lol, yes of course. OK check the rollers roll smoothly. You can replace them no problem if you want.

No,didn't misread. I just make it a point to do a filter swap whenever the engine is opened up, save for the simplest of valve cover removals. Just about anything can come loose from anywhere, and plug something up.

As I said, new filter is easy, inexpensive insurance against stuff that gets disturbed inside the engine, like the buildup on the lower part of any lifter getting released when that lifter is pulled out of it's bore.

I see. That sounds reasonable. Thank you for your help.

Thank you everyone for your help. I think I'm good to go, for now. I'll be changing the oil again in a few weeks, or a month depending on how much it gets driven.

When it actually gets warm, I'll inspect the lifters during the intake manifold gasket fix.
