I have a 97 ford aspire that i recently used auto rx in per the instructions. I now have a loud tapping noise that increases with engine rpm, that i believe to be a lifter. I switched from mobil 1 to valvoline conventional per the instructions. This sound has NEVER been there prior to using auto rx. Once the car warms up the sound magically goes away until you do another cold start. Anyone else has this issue? I emailed auto rx and they attributed it to "dirt being cleaned". well why would it be temperature dependent and i've driven it around 500 miles like this, i would have thought the dirt would have been displaced by now. I guess my concern is that the auto rx has changed the low temp viscosity and is now causing excess wear until the oil is warm. Any thoughts would be appreciated.
used AUTO-RX now have lifter clatterve

the way I've read it explained here is, the lifters are moving more freely now, so they are noisier.
have you finished the cleaning phase? or are you now in the rinse phase? because the cleaning phase makes all kinds of new noises, but it all comes together during the rinse phase.

no i'm only about 500 miles into the clean phase....i was just worried about doing more harm than good...
Hmm... I would be worried. My car started ticking when I did some heavy cleaning with PP and MMO. This I left unchecked and after a friend borrowed the car, he admitted to driving it really hard and racing it a lot. So the tick turned into a loud knock. On the rebuild, it was shown the oil pump screen became blocked with gook that had been cleaned and this prevented oil getting through the pickups to the top of the engine where the dual overhead cams were.
Not trying to scare you. Just sharing my experience and why I'm not a huge believer in cleaning an old engine too quickly, unless of course you can pull the pan and clean it down there and clean the oil screen after awhile when starting such a clean cycle.

Follow the directions for the clean phase, no point in pouring good money down the drain. Add a pint of MMO during the rinse phase. It will help break down anything in the engine that might be plugging up the lifters and the noise should go away for good. Clean properly operating lifters should not be noisy.
I would wait until the cleaning phase is complete before drawing any conclusions.
Also: I won't be stoopid enough to put other stuff into the oil now just to "rinse" it off.
Why don't you take your vehicle out on a long, hot highway drive to let it clean itself out?

The MMO for the rinse comment came from A-Rx moderators I've chatted with. They claim it works very well.
This is going to be a good one!

Follow the instructions and see how it goes. After a proper flush, you could see what zMax does, but I wouldnt mix adds.
I would not use A-Rx and MMO at the same time. In the rinse when the A-Rx is drained and fresh oil is in, there are people reporting using MMO and having better results. I'm just passing along info I got from a couple of A-Rx mods and users. In the end the goal is a clean quiet engine. This has been discussed before on Bitog.

the noise will come and go during the clean phase. just let it work. this is the same advice I got some time ago when I posted a very similar thread, here:
my arx experience

Just drain the oil and fill the crankcase up with diesel for the weekend. After two days drain the diesel, change the filter, and fill with cheap oil and a cheap filter. Take a spirited drive, get the engine good and hot, do a few italian tune-up runs, drain the oil again and fill with your usual stuff.
Nobody has ever done that, but I bet it would work great.

Follow the directions exactly. Don't make up your own directions.

So back your bet with your own engine and do it.
Or are you one of those who wants others to prove your theory?
I'm thinking the latter.

Well all my vehicles run fine. I never added anything to screw them up like AutoRX.

The first thing I would do is change the oil filter. The ADBV might be failing, or the filter might be full. It's a simple inexpensive way to trouble shoot.
