Weaker bottom ends? No, weaker rodbolts yes, and they only come into play when you spin the motor higher than 6500. There are people running 9's on the stock bottom end on 98's.
Oil Pumps go bad: 98-00 issue, only occured during very low milage 0-10k, if it didn't fail by then its not going to under normal conditions. If you do a cam and not an oil pump for cheap insurance and it fails, thats your fault.
Piston Slap: Nope, never heard of even 1 98 that has had piston slap, it seems that started in late 00.

You're right. It seems that '98s are the least likely to have piston slap. Also, of the 3 LS1s I've owned ('98, '99, and '00) the '98 is the only one that doesn't seem to use a drop of oil.

I had a 98 with 86000 miles on it....not a single major issue!

It just so happens 98's seem to be pretty big freaks compaired to the other years.....diffent cam sizes and lsas and all

I bought a 98' TA brand new in 04/17/98.Ran her up to 93K miles before we sold her and the issues were the AC compressor went out at 60K miles,power window motor and one of the little winshield squirter things went out on me...

Never used up oil,never had tranny probs (A4) and never had the dreaded piston slap noises..

98's are great cars and I would NOT hesitate to buy one again if I was in the market.I drive a 00' now only because I ran across it in great condition and it was in my price range...plus I dig the ebony interior over the grey...

i took my car to a workshop this morning, there was another one, 00SS with the most piston slap i hafe ever heard, my freinds 00 ws6 knocks like hell when its cold,

after i bougth my 98, i think that the ls1 motor is CRAP
but its one of the most fun motor i hafe ever come a cross though..

how is the ls6 motor? any known problems?

You'll find that thousands and thousands of people on here will disagree with you. A little piston slap when cold doesn't make the motor junk, plenty of motors will do that for 100,000+ miles and be just fine.

im just angry because mine is death with so few miles =(

no there is alot of thes cars here and.. i to many of them haf had serius engine failures..

but i still love the LS cars.. and will fix mine

My A/C compressor went out on me around the same time. Passenger side motor is a little slow (in comparison to the drivers side, of course). That infamous headlight noise due to stripped plastic gears, as well as lower (but still adequate) than normal oil pressure.

... and, of course, that horrible Monsoon radio (which all of us were subjected to).

Other than that, I wouldn't trade her in for anything. I've since replaced those pathetic plastic gears, installed a much better oil pump (when the cam went in), and will deal with the passenger side window motor when it finally gives out...

With just a lid, K&N (w/FRA), and a stall... ran a mid twelve second pass @ the track. Yeah, I was very impressed, being that everything else was stock, including it's tune.

LSWaaa?

lets say i do get a 98 LS1, could i put in ARP bolts in the stock bottom end and it will hold up?

LSWaaa?

great link!

112K still on the original clutch replaced A/C Compressor, Headlight motor, Fuel level sending unit all under warranty by 50k.
Since then I've replaced the waterpump, drivers window motor, Motor & Trans mounts, and bent pushrods from a missed shift.
She does use some oil but no more than a quart between oil changes.
This Car is my daily driver and has 20+ track passes and 300 or so street runs on it. So she is not really babied.
She Dynoed 300 RWHP and 322 RWTQ on a Dynapack with 109K miles this past sping.

The A/C compressor issue mentioned was due to the 98 programming, nothing to do with the mechanics of the engine, same thing would happen if the WOT shut off was set the same on an 02 LS1. It can be fixed with a touch on the tune.

Absolutely. People run 9's on the stock bottom ends on these motors with rod bolts.

mine has 86 and change on it, no piston slap but uses oil mostly on long trips. dont know wats up with that but im guessing its the pcv. i think i may have a bad o2 sensor now but i havent had any serious issues and still love it, great engines!!
