I am finally getting my 92 gts back with a freshly rebuilt motor and i was hoping to find out how the car needs to be driven in the break in period and how many miles does the break in period need. thanks

i think it goes along the lines of:
-no quick starts/acceleration
-dont go over 65mph
-oil changes every 100-500 miles

i believe those are some general guidelines to follow. Simply, take it easy for the 1st 1000 miles, keep on eye on your oil levels and when you change the oil, check for excessive metal shavings.

Another thing to do is to use dino oil to start with. You can make the switch to synthetic after some thousand miles (I think it's either 1 or 2 thousand, but I'd look it up if I were you). I guess something about the minerals in dino oil help the gaskets get a better initial seal.

I remembered something about beating a new engine to death to break it in, so I googled it: http://www.mototuneusa.com/break_in_secrets.htm
What do you guys think? I don't know if I trust it

run it hard? never herd of that. if the motor was built in ten minutes it may react diffrently to a machinist that has good rep and tooling. idk. running it hard all the time doesn't seem right . thats why we are here. to help =)

Good Luck with the break in. tell us how it went

during initial start up, you should keep the revs high, around 2000-2500 rpms to break in the cam and bearings. run it for 10-15 minutes like that. then you can drive the car. to seat the rings, you need to do a full pull. get on the highway, and put the hammer down. go as fast as your comfortable going, just dont be an idiot about it. after that, take it easy driving around for the 1st 1000 miles. use non detergent oil to break it in. do an oil change at 100 miles. its not a bad idea to do another in 500 miles like 19celica90 said. and definately run a magnet through the waste oil for metal particles.

Actually, the consensus on breaking in motors these days is to break it in like you are going to drive it. juggernauts advice on initial break in is correct. We had another more detailed thread on this a while back. See if you can find that one.

magnetic drain plug is a good investment as well i'd think

would magnets in the oil pan work good too? they are on my moms 92 grand prix and seem to help filter it at times.
