TomCleveland Posted January 15, 2005 Report Share Posted January 15, 2005 Are there any suggestions from Volvo about "breaking in" a new engine? I can obtain a new S60 2.5T but my local dealer wants to dealer trade it for a vehicle which is 250 miles away. The thought of having a driver get in the new car and drive it for 4 hours at 65 mph does not sound particularly good for the engine. The dealer says it should not be a problem. What do you think?

ROB @ VMS Posted January 15, 2005 Report Share Posted January 15, 2005 I drove my Vms C70 3 hours back right after it was built. You should have no problems man. Link to comment Share on other sites More sharing options...
JCviggen Posted January 15, 2005 Report Share Posted January 15, 2005 it'd be fine. Best thing is though if you are able to change the revs a lot...going for 3 hours straight at 2500rpm isnt ideal Link to comment Share on other sites More sharing options...
styx0r Posted January 15, 2005 Report Share Posted January 15, 2005 Modern engines are machined much more precisely then older motors. When breaking in an older motor, it was not a good idea to drive the car hard, until the motor and internals had ground themselves down to find their final resting place. Newer motors don't have that problem. It's actually reccomended by some to drive the motor hard to seal the rings properly. That said, avoiding a constant xxxx RPM is a good idea.

kenhoeve Posted January 15, 2005 Report Share Posted January 15, 2005 agreed. vary the RPMS and rev it some. Link to comment Share on other sites More sharing options...
S70 R Posted January 15, 2005 Report Share Posted January 15, 2005 they come some what broken in already, but your trip back sould not be a probelm, i work at a VW/audi dearlership and someone just bought a new A8 W12 and he picked it up yesterday and he left today to go on a 3 month driving trip in his brand new car!. it should be fine expect for all the rock chips hes gonna get Link to comment Share on other sites More sharing options...
Guest DougK Posted January 15, 2005 Report Share Posted January 15, 2005 vary the rpm's. Its cast rings, they seat almost instantly. 100 miles and you can drive it fairly normal... wouldn't be a bad idea to have the oil changed at 500miles. AFter that, just drive it like you stole it Link to comment Share on other sites More sharing options...
wattsat Posted January 16, 2005 Report Share Posted January 16, 2005 Not certain about Volvo, But I know that Porsche puts their engines on a test stand and runs them full out to redline before they ever go in a car.There are plenty of people that will argue the best way to break in an engine is to drive it HARD.

If it doesn't light in the first few seconds it goes back. It needs to go straight to redline or it goes back.Oh, ever notice how much oil pressure there is on startup :o Link to comment Share on other sites More sharing options...
850turbo Posted January 16, 2005 Report Share Posted January 16, 2005 i dono man....... i depends whakind of person its is if its like a 18 year old speed demon that will floor it every light that will not be good. so its basicly 50/50 maybe ask if u can go pick it up???? i dono if you want to do that though?

AutoX47 Posted January 17, 2005 Report Share Posted January 17, 2005 holding it at the same rpm without any load will likely file away all the cross hatch pattern on the cylinders without fully seating the rings and result in low compression, but they might break them in at the factory. There needs to be high cylinder pressure to make the rings seal (and varying rpm in neutral doesn't count) Link to comment Share on other sites More sharing options...
854TGA+ Posted January 17, 2005 Report Share Posted January 17, 2005 I say drive like somebody else ownes it! Drive hard at the beginning and the engine will respond nicely. Seen it many many times before, baby it and it will become a dog. Link to comment Share on other sites More sharing options...
JCviggen Posted January 17, 2005 Report Share Posted January 17, 2005 isnt there already an identical thread in performance mods?Anyway if it was my car, I'd slowly warm it up, when its warm gradually build up the revs and redline it a couple of times. Then try to vary the rpms as much as possible during the trip.driving it slowly (or too agressively) wont break the engine, but I do believe (as noted above) it can change the engine's characteristics Link to comment Share on other sites More sharing options...
matt1122 Posted January 17, 2005 Report Share Posted January 17, 2005 With modern volvo's you don't need to worry about breaking in the engine too much, the manufacturing process has come a long, long way over the years and so have engines. The car will take car of itself, you don't really have anything to worry about. Link to comment Share on other sites More sharing options...
