I have a Malibu with what sounds like the famous piston slap, however it doesnt go away. I replaced the lifters because I had to replace a leaking intake gasket anyway. It has new plugs and wires and has always made the sound even before replacing them. It sounds like it's coming from the top of the engine however I am open to any and all diagnostics. Please leave a comment. Thanks

2000 Malibu 3100 "Piston slap"?
This is My 2000 3.1 Malibu with the so called "Piston slap" It has
145,000 KMS or 90,098 Miles I have changed the defective gasket most of
these eventually get before it got bad enough to leak coolant into the
engine but this Car sounds like crap on a cold start and only slightly gets
better as it warms up. I also tried flushing the engine and changing to a
thicker oil to see if it helped but it never.

Fix It Right! - Intake Manifold Gasket Replacement (S1E4)
Demonstrated on a 2004 Buick Century 3.1L V6 FWD.
In this video, we demonstrate how to perform an intake manifold gasket
replacement on a front-wheel-drive 3.1L V6 engine, in this case in a 2004
Buick Century. This is a common point of failure on General Motors' 3.1L,
3.4L, and 3.8L V6 engines, which are used in a large number of passenger
cars across most of GM's model lines.

About the "Fix It Right!" video series:
"Fix It Right!" is a series of how-to videos intended to give
do-it-yourselfers basic instructions on proper vehicle repair and
maintenance. All of our videos show real repairs being performed on real
vehicles by real technicians in a real auto shop. (Repairs are filmed and
shown with the permission of the vehicles' owners.) Although there may be
more than one way to perform any particular repair (and in many cases there
are lots of ways!) we try to focus on the methods that will be safest and
most expedient for DIYers with limited access to tooling and equipment.
We will also occasionally be showing repair processes that are too complex
or dangerous for DIY, or require specialized tooling, expertise, equipment,
and/or certifications. Those episodes will highlight the importance of
hiring a professional auto technician for tasks that are not DIY-friendly,
and demonstrate why such tasks are best left to professionals.

How to fix p0401 egr code on 3.1 v6
Don't go out and buy a new EGR valve for $100. Heres how to fix it
yourself. If you have the code P0401 EGR flow insufficient, just clean the
passage way. Using a wire coat hanger or piece of flexible yet strong wire
and throttle body cleaner you can clean this yourself. Afterwards make sure
to clean out your throttle body of all the crud deposits. This engine is in
my 98 Buick century, along with Chevy Malibu, Chevy Lumina, Grand Am, Grand
