You are in the Chevrolet Lumina
What is this discussion about?
Chevrolet Lumina, Sedan
Mar 29, 2003 (6:05 am)
New here, but I hope someone has a word of advice... 2001 Lumina, 3100 engine, 35,000 miles, bought used October 2002. (Replaced a 95 Lumina, 3.1, that I loved dearly...60,000 hard miles on it in the three years after I bought it used, no problems whatsoever until engine said "AMF!" at 145,000.) In the last month, started tapping when cold, noticeably (turns heads). Runs silent when warmed up. In shop for warranty, they say GM calls it normal. "Small pistons, better gas mileage"...I'm just an occassional shade-tree mechanic, but that sounds odd. My predicament is this - they say they'll replace the pistons, but it'll happen again in a few thousand miles. Should I buy the time and have it done? Lose the car like a bad habit? Extend the warrranty? (Have to do that within next 900 miles, which will only take me about 3 weeks or so.) Never thought I could get soured on a Chevy, but I saw a couple posts back in August 2001 and November 2002 that didn't look particularly encouraging. 95 is still in the driveway, maybe replace the engine...then I can sing her praises again.

Mine improved when I substituted SuperTech filters for the Frams. I still notice the noise at times but I think it's normal because it's not loud. I would take the free piston replacement if mine were loud.

Saw some of your posts here, appreciate your input. I was leaning towards the free work, so that's nice to see. GM's explanation holds water? Was nervous because tapping was the prelude to the older Lumina's untimely demise.

For $1300, they'll extend my warranty to 65,000 miles. Nice to have, but that's a heapin' helpin' o' cash. Also, I'm a dirty liar. Old Lumina was a '94; wifemonster's is a '95 Mazda (her bad). Always screwed that up, especially when getting parts.
#534 of 857 Piston Slap
Mar 31, 2003 (5:39 am)
If you search on "3100 piston slap" in Google/Groups you'll find long discussions in several automotive newsgroups. GM revised the piston by adding a teflon coating on the skirt but there doesn't seem to be universal agreement about when you have to do something about it. I don't know if your car has the new pistons or whether GM would absorb some or all of the cost to replace them. Good luck.

Checked on your suggestion; I guess GM isn't quite as good as I imagined. Still my preference, but I'll be a bit more realistic in the future. They're doing the work under warranty; teflon coating on the replacements. Appreciate the replies and advice. Meanwhile, was the 94 just a lucky break, or was that a pretty reliable engine? Aside from regular oil changes, my PM habits aren't terribly impressive.

It's in lots of taxis which run up the miles--almost all the the taxis in Toronto are Luminas and they're in lots of other fleets. Not to mention the Buicks and other cars that still use them.

I own a '94 Lumina with the 3.1 motor. It currently as 180,750 miles and is still running strong. I've basically followed the maintenance schedule, changing the oil and filter every 3000 miles or so. I'm very pleased with the durability of the 3.1

Howabout brakes? I have 34K miles on original pads--do these go forever?
