Well, as I said a little while back, I gave my mom my old '94 century with 75k on it since she wrecked her '99 Cavy. Well it had what sounded like a lifter tick, now it has gotten worse to where it kinda sounds like a knock. It does have a small sputter when revving or flooring it. Tell me whatcha think it is.

that could be so many things....

an accessory with bearings going out, loose pulley, lifter tick, and I hate to say it but possibly rod knock (though I think rod knock is much louder).

Look at me with my mustang...I thought I had bought a car with a bad motor cause of the knock...turns out a crank pulley bolt snapped and was causing the knocking. May just be something simple.

very normal on 3100'* the normally quiet down after a few min of warming up almost everyone that i seen does that

Sounds like a hydraulic lifter :?

Rod knock is a hell of a lot louder. Personal Experience

X 2 actually x alot of times I've drooped more rods than anyone I know

Not a rod knock. Sounds like a lifter And an accessory bearing as well.

try changing your oil and refill with 3.5qt'* of oil and 1 qt of trans fuild run for 500-1000 miles then drain and fill with regular oil again

3100'* and 5.7'* make a lifter tick which is common and then they always go away

This one hasn't gone away, oil changes, even doing the cleaning with a little kerosene, didn't help at all. It has been ticking for about a year and a half.

It'* a bomb! Put a screwdriver up to the valvecover and put your ear against the handle. See if you can pinpoint it a little bit. It does sound like an angry lifter....

try the trans fuild trick

trans fuild has more detergent in it to clean that up

after doing many 3100 lower intakes i tend not to worry about lifter ticks on that motor cuz they all did it idk just my personal experience
