How do you temporarily quiet a rod knock? I have been told to add many things like thick thick oil, slick 50, and BG RF7, if you guys have any suggestion please tell me. THANKS

I did this recently to pass off a trade-in at a dealership... marvel's mystery oil (2 quarts) seemed to do the trick.

What is the purpose of quieting it down? Are you trading it in, are you selling?

If you are selling, I would be upfront about everything, for a trade in, I may do what you are thinking, but it still isn't right. I would fix it.

throwing in several cans of stp (do they still sell that?) or ''motor honey" (do they still?) or grounding the plug wire to the bad cylinder, may get you back home...if you dump it on a dealer or some unsuspecting individual, expect trouble to find you.

Don't do it ! Your conscience will bother you long after you've spent the money.
Unless of course you're trading the car in at your ex-wife's dealership

How sure are you that it's a rod? Normally, a rod knock is a double knock sound.

A ticking sound that varies with engine speed might be a lifter.

Have you sounded the engine with a stethoscope (or a big screwdriver) to locate the source?

I am with OldCorvetteFan.

Those I6s are super stout, I would be stunned if there was a rod problem. My brothers has over 200k on it, and a friend, the last time I spoke with him, had almost 300k on his.

Start car.
Put car in park.
Stuff your right foot through the firewall.

Seriously, its time to pull the motor.
