Now for the break in. Try to vary the revs as much as possible, with alot of short blasts. It is very important that you let the engine "brake" itself by just letting off the throttle and letting the vehicle slow down on it's own, while in gear. This creates a vaccum in the cylinder and forces the rings outward, which wears down the peaks in the cylinder's fresh hone. Do this for the first 20 miles, and then proceed to beat the **** out of the motor, up to it's maximum rev range, as long as it is tuned accordingly. As long as the bearings are within spec and the rod bolts were torqued correctly, there is NOTHING to worry about.

I guarantee you WILL NOT burn oil using this break in method. If you do, you probably have leaky valve seals or bad rings/cylinder hone, or maybe possibly even other major problems with alignment of the sleeves themselves.

 

Ok thanks when we did the new rings we put them in painted the car drove it twice and then took it to the dyno to get tuned

 

Today u pulled some hoses off to replace and there is no thermostat wounder if that's wat its causing
