Sadly my motor blew this past Thursday. I had a 94 LS with the stock B18b with 160k on it and I changed oil every 3000 miles and it never used any oil. The connecting rod failed and blew a hole in my motor. I was wondering if this was a thing that is common with that kind of motor?

 

not if it has been misused

 

could have had bearing damage before you bought it, not common but it happens. luckily the jdm b18b's aren't that expensive. order one up, install, drive, enjoy

 

Where did the rod break? Top or bottom? Did the bearing spin first? Any warning signs? Under heavy throttle or cruising?

Not very common, especially on a stock motor, but after 15 years things due tend to happen.

 

LS engines have small connecting rod bolts. Where the rod attaches to the crank is their weak point. Not common for babied engines maybe, but I've seen plenty of LS engines that get abused often throw a rod through the block. Done it myself once too.

 

im on the same boat as you my motor blew out just like that

 

Time for a swap. I say get a GSR, a bit more pricey but worth it
