what up,

Im getting some new piston rings installed, and i was wondering what was the proper break in procedure? i'v heard u cant take it past 3k RPM, and u shouldnt drive on the highway?? When my car is finished the only way to get home IS the highway, so what should i do??

thanks

 

my tried and true ring break in procedure:

use only wd-40 on piston, rings and cylinder wall for initial install.

once assembled, rotate the engine several times.

crank the motor with the fuel injectors unplugged and spark plugs out until the oil light goes off.

start the engine and immediately rev from 2-5k util it warms up.

go drive it hard, no need to baby it.

Change oil and filter.

Done.

 

see thats the confusing part, some ppl say drive it like u stole it, others say baby it for 500-1000 miles..

 

don't drive it like you stole it. Just hold the revs up until the motor warms up. Then set your idle and timing. After that turn the car off, and change the oil. When that's done, then proceed to drive your car, reving it up to 4k, then letting the engine bring the revs down, don't use your brakes. Each time you do it, go a little higher (5k, 6k, redline), each time letting the engine bring the revs down.

What'll happen is the when the engine is reving down, it'll cause the ring to push into the walls helping them seat.

I used this method and got perfect compression, straight across within a few miles.

 

ok sounds good..what about driving on the highway with a gsr trans lol..i guess ill only be able to do like 45-50mph

 

up..

 

ive heard just drive it normal and not have ur RPMS at the same place cuzz it might glaz the cylinder walls..just keep ur rpms up and down

 

iv heard that also..ill just take it easy for 500 miles

 

going off "ive heard" is not a good way of doing things. How about contacting some people that have really built engines with good results. light driving for 500 miles is a joke. rings should be almost completelt seated by the time you drive down to the street. I'll stick to my method of ring seating as long as the results are stellar like they have been. Here is a good thread you should read:

Jeff from IB knows the "proper" way to seat some rings http://www.importbuilders.com/breakinarticle.htm
Like a few have said already your rings should be seated within about an hour of driving if not in the first 15 minutes. Constant rpms aren't good to start off with either. Maybe you need to drive around a little before you get on the interstate?

explain.

and it takes a lot to screw up an all motor car. driving the car turbo with improper tuning can destroy and scar up pistons like in his pictures very quickly.

 

 

I run Valvoline conventional motor oil until it has ~1000 miles, then I switch to synthetic; either Valvoline VR1 or Mobil1 Extended Performance
