Hey gang,

I have an 87 with 130k on the clock fresh off an intake refresh with tapping lifters. Is there anything that can be done do quiet them down a bit?

Bertrand Daoust

Have you drive the car a bit?
Sometimes it only needs to be driven to cure this.

Also, you can try this:

Didn't try it yet but have two bottles waiting in the garage...
Will next year.

Give it an Italian tune up.

is it clacking cold, hot or both?

Be sure the cam plugs have been replaced with pins. Search for this, as the symptoms are the same, clicking lifters.
There are several threads on this subject, call one of our vendors for details and pins. This is a must do for early S4s.

What's an Italian tune up? They tap both hot & cold.

drive fast, rev high. Has a way of cleaning things out while at the same time maximizing your enjoyment. My car has sqeaky clean valves and super quiet lifters

Swepco 502.
Have some head room on the dipstick.....
Drive the car until it's thoroughly warmed up (read heat soaked)...
Then while the car is idling, add a bottle or two of the 502.....
If it's gummed up lifters, they'll clear pretty quickly..... if it's mechanical...well then you have other issues.

I should mention....
You are using a good 20/50 oil with adequate ZDDP....right?

Thanks for all the info guys. Yes, I'm running Royal Purple. I'll try and find some Swepco locally.
