    Smoking Rover V8?

    I have a Rover 3.5 which has had new bearings and rings, it runs really well std spec with a modified manifold to take a Dgas 38 webber.

    On cold start it is fine no visible smoke, when at temp according to a mate following it shows a small amount of oil smoke at gear change.

    But when hot starting it throws out a large cloud also when pulling away there is some. it is using about 1/5L for 300 miles. Left side is the worst.

    Compression is just over 10 bar on all cylinders and the plugs are clear. The crank case breathing is just to the air filter.

    My thinking is valve stem seals ( which have been replaced) or guides. Could adding pcv valve to the system help?

    Any thoughts or suggestions before I take the head off.

    Cheers

    Rich

    Well after spending many hours and lots of money on rover v8s in the past ( they sound good and fairly light in weight ) I'd say fit a small block instead? But I'm sure like most your on a budget ? And my meanderings don't help..

    You are on the money with the PCV. The rover lump is designed to run negative pressure in the cranckcase so I would get the pcv reconnected and see how it goes.

    Rovers will smoke if you put too much oil in. Just 1/2 a litre over the mark can do it.
    Check that the dip stick outer tube is fully home.

    No expert but have an idea if the stem seals have gone brittle the engine will smoke when started from cold
