The best way for running in your Rover V8 Engine.
The best way to run in (bed in / break in) any rebuilt Rover engine is as follows;
For the first 500 miles we recommend that the rpm is strictly kept to a maximum of 2500rpm.
The next 500 miles can be kept to a maximum of 3000rpm. After you have run in your engine for the first 1000 miles, we suggest that from here on, a steady increase limit of 500rpm for every 100 miles. This may be overdoing it a bit but it's good and on the safe side too.
To break the engine in evenly the following is also relevant;
Transmission breaking helps to bed an engine in better, that's gently using the gears to slow you down rather that your footbrake. This causes opposite thrust on the pistons and balances breaking in really well.
Rebuilt engines may have graphogen grease in there assembly to aid bedding in and this will cause the oil to look blackened very quickly and is very normal.
No special oils are required for running in your Rover Engine, but always use good quality high detergent reputable oils. Once done, we recommened you run your engine on valvoline VR1 from there on in.
Finally, during new engine run up times always keep an eye for leaks in oil or water, that if unchecked, could lead to premature problems.
