alright, i bought a 2000 trans am with 30k miles. It blew blue smoke and consumed a quart every 800 miles or so. I bitched at the dealship and told them to fix it, so they swapped me a new LS1 out of another car and the new motor they put in had 18,000 on it, DOES THE SAME EXACT THING. Is this normal? is it okay to see blue smoke when i get on it, and eat oil like a SOB. I cant belive i went through two LS1 both under 30k miles and they BOTH smoke, they both smell like fricken 2 stroke. WHAT SHOULD I DO?!?!?! SHOULD I GET RID OF IT AND GET OUT OF THE GM WORLD AND BUY A STANG!?!?!? IM PISSED.

The dealer put in a used motor?

There is an oil consumption issue with LS1's, but nothing like you describe. My old '00 Z28 would burn a quart every 3,000 miles or so. There was no visible blue smoke (oil being burned up). Have you had a compression/leak down test done? There must be some other problem than the normal piston slap/oil consumption thing.

...and as for stangs, my '03 Cobra with 6,000 miles on it has been sitting in my garage for 3 weeks with overheating problems.

i know 4 other kids with LS1 Fbodies, and 3 of the 4 smoke, like u will see a puff at shifts or when u get on it. These ******* things suck.

Have U tried a catch can and the other Mods for oil consumption, mine Burns oil, but aslong as its not a continous smoke I just put oil in it. But with my new catch can it has gone down on the consumption.

Let me be the first to crap all over this thread-- I Believe this is for New LS1 Enthusiasts-- not guys who are mad because they have ruined their cars. Isn't there a junkyard or somewhere else you guys could post? Go ahead and get your Mustang-- most of them come with a hole shot.

Are you looking for help or just bitching about it? If it's the latter, take it somewhere else. We'll gladly assist if that's what you're here for.

Now, let me ask you a question?!?!!? If they SUCK so bad, why buy one to begin with?!?!!? Especially if you knew your friends LS1's also smoked?!?!! HUH?!?!!? Remember, you're just a little pissed right now. Cool down and think about it!! LS1's DO NOT suck!!! YOUR DEALERSHIP SUCKS FOR SELLING YOU A BAD CAR!!!!!! You should go after them to fix the problem PROPERLY!! BE foreceful!!! AND LET THEM KNOW WHAT THE DEAL IS!!!! REMEMBER, they work for you, the customer!!! GOOD LUCK & let us know how it goes for ya!!!!!!!

relax cowboy. get it checked out somewhere else and have the warranty take care of the fee's. or something along that matter. relax and quit talking **** about the ls1. its a good motor, just yours isnt the best. RELAX!

I have a 98 Z28 with 103,000 miles never had a problem and it is still running strong. But whatever.

That sounds great in theory. Too bad GM is the proverbial 500lb gorilla.

I drove a 2800 mile trip to Miami Beach FL from PA and back and didnt burn a teaspoon. I ended up driving the car another 1000 miles after the trip and still not a drop. I changed the oil and have been driving it for about 2000 miles since, so I checked it yesterday and its done a 1/2 quart. I have read before the LS1's are known for this.

This is def the dealerships issue, take it back on them. I can't believe they replaced it with a used motor. They will take advantage of you if you are not careful. Good luck

my 98' ls1 has all kinds of mods, including nitrous...and will burn 1/2 quart tops between oil changes, come to think of it i've never had a single problem w/ the car...the dealer must have gotten a bad batch of ls1's, mistakes happen...that is what the warranty is for-and ive never heard of a dealer using a used engine to cover a warranty problem...smells fishy to me.

chill out about doggin the ls1's, remember you are in a ls1 domain and saying your goin to purchase a mustang over a f-body is fightin words IMO.....if you want to bitch about how ls1's suck, there are plenty of mustang message boards out there that will play the violin for you...the ls1 is an excellent design and has much to be proud of....so chill out and enjoy your ls1

I use about a half quart after about 10 passes at the track. Alot less during normal driving. Quit bitching oil is cheap.

A little smoke on the shift in normal, I've seen it on a lot of cars. I've had 2 LS1s and neither uses/used very much oil, always on the full mark on the dip stick. I did have oil consumption through the PCV, not enough to smoke though.

I think all the dealer did was change your bank balance. I doubt they swaped the motor. By the way, my ls1 has 90k and and is great with oil. I only have to add at oil changes, though I check it regularly.

I love my LS1


Oil consumption is almost non existant if you drive it like a grandma. Normally i burn 3/4 qt every 3,000 miles.

I dont beleive that the dealer even changed your engine, I've got a 98 w/ mods and n2o and I get no smoke and have no oil consumption issues, I've also had the car since it was new so I know how much abuse its had........(alot)

My `98 is a daily driver with 91K miles and has never had an Oil consumption problem.
In fact I still have the original clutch in the car, How many can say that ?

i hate ls1's also!

they have to much power.
women hate when you work on them all night long
they are as reliable as your old black lab
they cost to much
they are addictive
you can spend 2000 on the car and not think twice but u go to McDonalds and order 2 double cheeseburgars so u can afford the 2000 u dropped LOL
