So im going to pick my car up tomorrow or thursday, but im 150 miles away and the motor is freshly rebuilt. I need to break it in but in order to get home i need to be on the Highway which is at a constant RPM and there BAD for the rings? How about can i do this on the highway. Im thinking like going 40-60, like either leaving it in 5th and let it slow down and increase it to 60 or 70 slowly and let it drop slowly back down again or slowly going up to about 70 and put in neutral and let is cruise to about 40 and put in 5th and get up there again... Please help me out...

 

Why don't you just flat-bed your car home? Either find a tow dolly or get a buddy with AAA membership and have them haul it. The extra few miles charge(s) is worth it. I would rather pay that than redo my piston rings.

 

Break it in on the dyno.

 

yea you should break it in on the dyno...

 

ur fine.. let it idle for a good 10-20 minutes 21st change ur oil n drive thsat **** home dont be asfraid, if it breaks, then it aint built right

 

let the car idle for awhile. then drive it around the city for awhile....maybe 30-50 miles, then hit the highway, you'll be fine, keep her under 4000 rpms.

 

rings should seal in the 1st 10-20 minutes of idle.. run non-detergent straigh 30w oil for the 1st few hundred miles.. change oil alot, dont be afraid to drive it, show her whats coming

 

Yea Im thinking about going around the city for about an hour, that should put some miles on it then hope on the highway and try not to keep the rev at a constant rpm...
