    I know this sounds like a rediculous question but here's the back story.

    2 years ago I ground all my valve seats and now need to check the clearances so I can get them back in-spec.

    Over the last 2 years my 2 to 3 to now 4 year old has absconded with many of the parts that were laying out on my workbench. I have recovered all the parts save 2 of the washer-head bolts that hold down the cam caps. I have them on order but they will not arrive in time for me to install them before my day off this week.

    My question is this: If I use 2 bolts on opposite corners of a 4-bolt cap will it be strong enough to allow me to turn the motor over by hand to check clearances or might I crack/warp the cap and be screwed royal?

    Anyone have experience with this?

    Thanks!

    No.
    Ridiculous.
    Disastrous consequences.

    Go to a Hardware Store and BUY a complete set of Cam Cap Fasteners.
    Hardened <--- Cap Screws. HARDENED. Match your Bolts.
    Put the Hardened Cap Screws in place of the missing ones and replace the others to keep the Tooling together.
