Update: Noisy Lifters after oil change

Interesting, Doc. Glad you found the culprit. I've got a question for you. I bought a "new" '04 Sierra. Should I wait until the 1st oil change to put Mobil 1 in her, or go ahead and do it now. She's got just over 1000 miles on her.

Cheers, Kyle

Well you cant change it BEFORE the first oil change. Think about it. Kinda like something is always in the last place you look for it, because you stop looking fo it once you've found it. BTW, you'll love it. Mine's got 26K on it and it runs like a bat outa hell. Had a few relatively minot problems. Driver's mirror heat (twice) replaced mirror both times, now the left mirror heat is inop. Radio goes dead for seemingly no reason (pull the fuse fixes it), replaced the radio. Still goes dead, but now I can reset it by turning it off then back on. All on warranty of course.

I had a feeling the problem would go away after the oil filter swap. Just because you said it wasn't there before, and your reputation of being quite mechanically savvy. But that is strange, I've had problems with "ONE" oil filter but after changing it even with the exact brand the problem went away.

Very strange, but glad you aren't clattering.

Maybe next time:

Doc should use Motorcrap filters!

They're made by Wix.

LOL

A few thousand miles isn't going to make much of a difference either way, so in the interests of your wallet I'd just wait until she's due for a change and switch over then.

Doc

It is weird as hell eh? Has me scratching my head............... I too have bought "bad" filters on occasion, but after replacing with the EXACT same filter the problems subside. This was 3 or 4 (can't remember exactly) filters bought at different times at different places. I cut the Delco filter open after the change and couldn't see anything physically wrong with it.

Oh well, The P1 filters are 1/2 the price of the M1 filters and have about the same single pass and multi pass numbers, so looks like I'll stick with em'.

Doc

Not sure about M1 syn oil because it isnt 100% synthetic but years ago I used Amsoil 100% syn and they said do not put in until 12,000 miles, after engine is fully broken in. It was suggested that a tach be installed before dumping out the regular oil. I did this for kicks. When i installed the new 100% syn oil the rpms came up 200 rpm's. Now that's slippery oil. I think Amsoil is still around now but it was pretty pricey back then. I dont use either now, I dont care anymore its a freakin truck! LOL

Doc wonder if you got some counterfeit ACD filters. This link has a discussion & information on the issue.

Now isn't that interesting? Nothing is sacred at all.

Brian

Well I'll be damned! I wonder if that was it? It would make a helluva lot of sense. I'm going to go investigating on my lunch break tomorrow and see what I can dig up!

Doc

Went into Advance today, ,and saw what is being described here. Started a new post to ask if anyone else has seen it.

Never have seen any of the Mexican made AC's but have heard of it. Hell they can't be any worse than Allied-Signal's finest. ;-)

I don't go to AutoZone or Advance anymore, as I am so sick of the BS that you get out of these places. And their quality is pretty sub-standard IMO. I'll go to NAPA, Bumper-To-Bumper or Jopac if I need anything. They are more knowlegable and the parts quality is much better. As far as I know, the Wix/Napa Gold filters are still made in USA by good ol' Dana.
