    Cylinder head check if warped

    Hi,

    I am working on a 951 DI engine and a local dealer told me that I need to check if the head is warped when I took the cylinders in to get bored. They said that it takes a lot of time to flatten it and can potentially cost me 2 to 3 hours of labour. My question is is this something that I can do on a belt sanding machine with a light grid paper or should I leave it with the pros. I do nit have a sander but the labour cost will be the same as a second hand one. What is involved in correcting a warped cylinder head?

    Hi,
    So I found a video on the Web of a guy who skimmed a head using a flat surface and sand paper moving up in grids until a smooth polish. Is this advisable? Still not sure how they do it at the shop? Any suggestions will be appreciated.

    In a shop they put it on a Bridgeport/mill and cut it. That's the CORRECT way.

    Hi

    Thank you for the response. So do you reckon I'll still be able to do it on a flat surface with a very fine sandpaper or would not recommend it?

    First you need to determine if the head is even warped in the first place by using a true straight edge (not some dinged-up ruler), before jumping to conclusions. It shouldn't have warped, unless you overheated the motor, or head-studs were improperly torqued/un-torqued.
    If it is indeed warped, there's no chance in hell you'll sand it out, it needs to get milled.
