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
Chevy 3.1 engine problem. Fuel pressure regulator

problems, and how to check and replace the regulator.

2000 Chevy Malibu MAF Ground problem
This is a good video on how to check sensor grounds using a voltmeter. Once
you get more comfortable with this type of testing, it is far more accurate
than the ohmmeter. The key though is to make sure the circuit you are
testing is "loaded".
Also to all of you "free diagnostics" parts supply companies. YOU CANNOT
CHANGE A PART BASED ON A TROUBLE CODE!!!!!

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.

3100 V6 Ticking Noise
96 Skylark, 3100 SFI V6. It's made quieter ticking sounds before but not
nearly this loud. I've been using part synthetic high mileage oil for
almost a year, just dropped in some Mobile Super Synth and this started up.
Lifter tick? Piston slap? Knock? Something else? Apologies for the
crappy camera work, I was trying to focus on sound and I don't usually
record video. :\
When it started it was erratic, and then it could only be heard at a LOW
idle. Now you hear it until the engine drowns it out at higher revs.
2001 Chevy Malibu 3.1L rod knock
Vehicle had intake manifold gasket replaced, throttle body and IAC cleaned.
It then started stall while test driving, followed by starting to make this
noise. The day after this video was made, I moved the car into my driveway
and it stopped running for good, refusing to turn over. Once I opened it
up, found one of the pistons had disintegrated and a chunk of it got wedged
in the crank. I also found the head of a valve. My best guess right now is
that a valve seat dropped into the cylinder and started to rattle around
until it broke the valve, which then busted up the piston. The engine in
the car has since been replaced and now runs like a champ.
