Outer Limits 4x4 Board

got my engine rebuilt the block got machined cause it was warped and the head was machined aswell. so it has lots more compression. the mechanic said dont take on the beach for 1000km and take it slow. is this right?

no, why would you trust the mechanic who rebuilt your engine when you can trust an internet forum where anyone can throw in their .02c worth. I reckon you should take it to thedrag strip and challenge all the Commodore blokes to some foot to the floor drags

Do a search, been talked about before.

But i heard a few times, drive it like now like u want to later.

U may have have to run on premium as well to stop pinging, depends on your compression.

hey nothing wrong with wanting a second opinion, you don't even have to believe the second opinion but it can be comforting to look at different views.

Me personally i would probably baby it for the first few hundred let all the bit's and pieces set into place... don't strain it, let the oil lube it's way to every crook and cranny.

Then as Nicbeer said, rev the hell out of it, push it to it's limits on flat ground then tackle something harder. After all it is going to break do it early when you can go back to the mechanic and say ' hey i expected you to fix it.'

Sounds brutal but really if it can't hold 6500rpm on the highway or climb a sand dune then it's not performing to the way it was originally design

Drive it the same way you drove it before you got it rebuilt.

Now yor talkin Grimbo lets put some serious stress on the rings bearings and the like....

My 2c worth treat the baby with respect (the zook I mean) Drive it normal ie dont thrash the livin shit out of it. You'll know when she's run in then get it tuned again and take it for a thrashing you know she''l take it....

recently had mine done. drove on open road as normal. pushed it throught the city as normal. seems fine now, done 10000kms and goes a bloody treat

when i ran my engine for like 10mins at 2000revs like the mechanic said the temperture went up half way inbetween the middle and the red. this wasn;t normal before but i broke the heat sensor putting it in so i got the heat sensor off the 95 engine and put it on the 89 engine that i got rebuilt. also there was no wind. what was with that... i thought it would sit there for ages idling at 2000 revs.

pin the throttle for a few minutes with out any coolant in the engine should get the compression back to what it was before the rebuild

Not good for any engine to stay at a given rpm for a while.

Good to vary revs when bedding engine in.

General rule of thumb:
Don't labor the engine and don't over rev it. Long runs at varying speeds (rev's).
