    Getting the best out of my engine

    Hi, I've just had the following work done on my car, new valve steam seals, oil control rings, hone the bore which has cost a far bit of money I was just woundering if I needed to take special care when driving considering the work its had done? anyone had this previously done to their car? any help would be much appreciated

    Personally I would take it easy for the first 500miles or so, get another oil and filter change done at that point and then drive as normal after that.

    10 x 40 Semi-synthetic, Is that what you would recommend?

    Have you been advised how to bed the new rings/bores in?

    That's the only thing to worry about:

    Mineral oil first, nothing semi or fully synth, cheapy horrible oil is the key

    30-40 miles of:

    4th gear from 2000rpm or so, foot to the floor until 50mph or so then let off fully and let the car slow down on its own until 30mph

    Repeat for the 30-40 miles as listed. Full throttle forces the rings against the bore and creates a good compression seal. Letting off allows the rings to cool slowly reducing the chances of the bores glazing.

    Oil change for more mineral oil.

    Add 1000rpm to the max revs every 100 miles until you hit max rpm on the final run.

    3-400 miles should let this work, then change oil for normal 10w/40 semi or fully synth.

    Running it in gently will not bed the bores/rings in correctly, and using anything but mineral oil will pretty much make the bedding in process pointless as it is too lubricating and stops the bedding in process from happening.

    Once the proper oil is in, go for it

    Follow the above and get on to them ASAP about mineral oil.

    Mine was rebuilt last March - 12k later and no oil loss at all.
