Life Expectancy for the LS1

**79Firebird_99TA** · 12-31-2013, 12:04 PM

I've been wondering how long I can expect my engine to last. It's at 260,000 and still runs great. I use a quart of oil between oil changes (3,000 miles). Other than that, and a little piston slap on a really cold day's first crank, I have no issues. The engine is also bone stock.

As long as its taken care you wont shouldn't have any problems for years to come. i have seen one with 300k-ish. Motors are stout to begin with.

I have a friend with a 2000 Z28 that he uses as a daily drive and he has been putting in a quart between oil changes for years. He is waiting for the engine to blow so that he can build his dream engine but his LS1 is not cooperating and now he has 382k and he still get over 20mpg. Proper maintenance and normal driving habits are key to long life in any engine. My friend think he can get 500k out of his Z.

I have 35k and I use oil between 3000 mile changes I'm looking at a catch can... sounds like you'll never need to swap yours out, unless you want to...

69,000 and mine spun a bearing.

My T56 broke at 12,000 miles

. It happens.

Encouraging posts except for the t56 and the spun bearing. I've never really dogged mine ... it's been my DD since day one. If I still have the car when the engine dies, I'll stick an LQ9 in her.

Those of you using a quart inbetween changes, really look into re-doing your PCV systems. That is there your extra oil is going, right into your intake. I would suggest moving to an 04+ valley cover with a catch can as additional insurance.

Still will eat some oil regargless. I have both and I know some who have both and it still eats some oil.

Not too worried about that quart. I think what I'll start doing is add one quart at 1500 miles (after oil change). I hate it when that low oil light comes on at 2500 or so miles after oil change. Almost feels like a waste knowing that I'm going to be changing the oil in a week to 10 days.

**35th-ANV-SS** · 01-03-2014, 08:36 AM

Silly question, but how much oil do you put in it to fill it up? Including the oil filter.

**79Firebird_99TA** · 01-03-2014, 08:37 AM

5.5 quarts.

**35th-ANV-SS** · 01-03-2014, 08:38 AM

I figured that would be your answer as I know you are pretty up to speed on things. Just wanted to check.

Thanks man ... I figure I'd better have an idea ... or a deep pocket - LOL .... not to mention, the thought of some shop's hands on my TA would feel like some form of molestation.

I feel like I burn oil at WOT, but my level never really seems to change. I have leaks all over the place though, so it's probably PS fluid or trans fluid or brake fluid...or....lol

**RONS98TA** · 01-04-2014, 06:26 AM

Iam at 84,xxx and dont burn any oil. I drive my car hard, but only on nice weekends. I prob dont put 3k a year on it. I did however notice before the pcv delete, I did use a bit of oil. Now with the oil breather set up, it def seems to have helped if not eliminate my oil consumption.

Do you have a write up or link to what this is? If like to do this

**RONS98TA** · 01-04-2014, 07:37 AM

I dont have a link or write up, but iam sure some of the other more computer savy peeps on here will have that info. In a nut shell, it just takes the tubing coming off of the valve covers and re-directs it to a different location other then the intake manifold. Most use a breather tanks (ww.summitracing.com/search/part-type/oil-breather-tanks?SortBy=Default&SortOrder=Ascending&tw=breath er%20&s) The org factory design sucks oil from the valve covers into the intake then into the motor. This not only sucks oil from the engine, but will also lower your fuel octane rating from lets say (this is just an estimate for example) 93 to 90.
