    I'm super jealous of your pegboard, that is a lot of well organized stuff that can tackle 95% of car work i'd say.

    crank endplay was 0.0065", maximum spec is 0.012"....buuuuuuut I took the crank to the machine shop to get checked and the #1 main was 1.5 thou below min. The #1 main bearing showed bad wear.

    How does the valve stem to guide clearance measure?

    That motor is pretty rough, I would think about a later 5m or better yet, a 6mge. The 184psi in #6 is telling too, ton of carbon in that cylinder? Spec is 164psi for that year.

    Hey welcome to the board! Always great to see another BC enthusiast. I'm from the island myself (sort of). If you get this thing together in time, bring it to the All Japanese Classic car show in North Vancouver on August 28th. I posted details in the events section. Come and I'll bring you an uncracked terra cotta dash pad, I have one that needs a home.

    Here's my measurements for that, as you can see all exhaust are within the max spec. Two of the intakes are just beyond the max spec.
    It was very difficult to get a repeatable measurement, so each number is an averaged result.
    I had the machinist check them, but his technique was to "feel" the stem-to-guide free play by hand rather than with a gauge. After wiggling them all, he said "I wouldn't do the guides if it were mine". Legit ?

    Ex1 0.0033" (max spec = 0.0039", standard spec = 0.0012" - 0.0026")
    Ex2 0.0035"
    Ex3 0.0031"
    Ex4 0.0037"
    Ex5 0.0034"
    Ex6 0.0036"

    In1 0.0031" (max spec = 0.0031", standard spec = 0.001" - 0.0024")
    In2 0.0031"
    In3 0.0033"
    In4 0.0034"
    In5 0.0031"
    In6 0.0029"

    The valve stems were straight as an arrow, no wear. Measured 0.314" up and down each stem, which is right in the middle of the spec. All valve mating surfaces were in good condition.

    My setup

    Yeah its a little rough for sure, but after the machining it should be as good as new. I've already delivered the bits to the machine shop so there's no going back now. Besides I want sure how I would've got a replacement motor, and it would be in unknown condition. I'm going one size under on the crank.

    Thanks for the invite, I'll probably wont be ready in time. A replacement crack-free dash is definitely something Id be interested in.

    COOL!

    Back when I was building high-perf engines, Clevite "CL-77" bearings were the hot setup.

    Starting on some bodywork while I'm waiting for the machinist. It's the dreaded battery acid leak damage, along the lower rad support is bad. Now's the time since the engines out. Pics soon.
