    Repair ideas

    I couldn't do either but would be concerned the heat may warp the mating surface. On the other hand if you knew someone in the Calgary area who would be interested I would like to talk with them.

    Repair ideas

    Hi again I need some ideas on how to repair this head I just picked up. As you can see in the picture someone tried to drill out a stainless steel pin used to hold the chain rail guide. The result is part of the shoulder used as structure has been removed and a new hole has been made in the...

    This is not a DIY im willing to tackle but I did find post 3 by Peter T gave me some valuable insight if I was inclined to handle this myself.

    Thank you for your comments, advice and further education. I managed to locate another newer machine shop who has had some experience with this diesel engine. He has run into this issue in the past on the same engine and recommends shaving .35 mm off the top of the stems without issue. He claims...

I'm really not to keen to get any additional work done at that shop since the never followed my instructions to begin with. The sodium actually must travel up the stem a...

    Is this possible

    Inlet valve diameter 38mm exhaust 35mm. Material to be removed .3 mm tolerance plus .1 need to verify after removal. Some engines use valves that are hollow and the void is filled with sodium.

    Is this possible

    I'm not certain if this is even possible but ideally I would like to shorten 12 valves by .3 mm. A machine shop took off too much of a seat and the lifters are not allowing the valves to close completely. Valves are not sodium filled but I assume are hardened. Your thoughts please. There is only...
