    you do realize that type of aluminum beer keg ,
    gas tank repair, minor intake manifold cracks,
    minor porting screw-ups on aluminum intakes,
    like sealing pin holes and thermostat corrosion repairs ARE

    generally done like this





    BTW it should be obvious, it would be smart to fill the empty beer keg fuel tank with a complete flush of argon or CO2 before using a torch near any fuel tank,
    if you don,t have a welding tank with shield gas handy your local super market generally can sell you 5-6 lbs of DRY ICE, if you pour all the fuel out and flush the tank with water and a few drops of dawn dis soap then rinse, then drop in 5-6 lbs of crushed dry ice and cover the exits with duct tape then wait 20 minutes the tank will be filled with a low pressure cloud of co2 gas making an explosion impossiable
    and you could very easily do it faster, cheaper and better yourself

    Dent the cracked area in a little so that when you grind it smooth, there is still some metal thickness underneath.

    The owner of Osborn radiator called me back and said to bring it back and he would weld it
    again for free. With three overlapping passes on the weld this time it's much wider than the
    first weld. It's off to the Elite Polishing to get the keg redone. Also taking my two piece valve
    covers and the Summit aluminum water pump pulley.

    Got to get ready for the cruising season that's not too far off.

    is that the only major issue?

    Yes, that's the only problem with the keg/fuel tank.

    Wrong, it's filled with gasoline instead of beer.:D:rolleyes:
    Or you could fill it with moonshine and still run your engine on it.

    Did a search here.

    Got around to installing the new Fluidampr balancer. I did like Love302 suggested with the
    silicone sealer, that should fix a small leak I had with the old balancer.


    I bought a set of water pump pulley shims that come in 0.60, 0.90 and .120 inch, but I didn't
    need them. Alignment was perfect.


    Summit Water Pump Pulley



    I also needed to check TDC with the new balancer and adjustable pointer. Since the last balancer
    was 8 inch and new one is 6-1/4 inch I had to buy an new pointer.

    I emailed ARP to find out what they recommended for torque when using Loctite Red 262 with
    their bolt. See their email response at the end of this post, but they suggested the same torque of
    80 ft-lbs as they did with their lubricant. I thought it might be different since they always
    recommend you use their "ARP Fastener Assembly Lubricant #100-9909". No need to purchase
    a tube, normally they will send a small package with their products.



    ARP Email Response

    Hi Rick,

    Thanks for the inquiry,

    You can use the red Loctite on the threads and apply lube under the head of the bolt, the
    torque would be 80 ft. lbs.

    Ok, I'm baffled ??? I want to install the distributor in the correct position. I'm trying to find
    the compression stroke by putting my finger on the spark plug hole while I turn the crankshaft.
    I've done this several times and it always wants to push my finder off the hole. NO pushit as
    you remove your finger. I've tried the following with NO difference, not even slightest indication
    of compression.

    - Checked every time the crank was turned, not just when the balancer degrees showed TDC approaching.
    - Added oil to the cylinder
    - Pulled the valve cover and watched the valves. After the intake closed, then watch the balancer degrees.

    I could go by the intake valve closing, then set the balancer at 10° BTDC. Install the distributor pointing
    at cylinder #1.

    But I want to know why I'm not getting indication of compression..... comments ???

    How fast are you turning the crankshaft? It will not hold compression forever.

    This does work: I could go by the intake valve closing, then set the balancer at 10° BTDC.
    Install the distributor pointing at cylinder #1.

    I turn the crank while holding my finger on the spark plug hole. How fast, well ...... how fast can
    one turn the crank with a breaker bar.

    It's always worked before.

    Have you done the very same thing ????

    One more thing I've done is to removed the valve cover. The covers you see in the photos
    are the old covers that are not as tall as the 2 pieces covers I have always had installed. But
    that made NO difference. I thought maybe they wore restricting the valves from completely

    Turn the engine over by hand with a breaker bar at 160 rpms.
    If you can not then use a starter bump switch to engage the starter motor.

    loosen the rockers on both valves on the cylinder your trying to find compression on at least one full turn, out,
    on the adjuster rocker nut and try again,
    if the piston is moving up the bore its compressing trapped gases if the valves seal,
    its very unlikely your crank broke ,
    but its not all that hard to have the valves slightly out of adjustment so they don,t seat and seal.

    I did this, checked the pushrods and they have plenty of clearance. I can feel them both with plenty
    of slop. There was NO change, still no compression !!!

    So to make sure I knew what to expect, I move to cylinder #3. There is no doubt in my mind now,
    there is NO compression on cylinder #1 !!!

    I wanted to compare the valve retainer heights from the intake to exhaust on cylinder #1 .... I get 0.060
    inches lower on the intake valve. To make sure I had a valid comparison, I moved over to the cylinder #3
    intake took the same measurement across to cylinder #1 intake. Guess what I got the same clearance
    within 0.002 inches.

    My guess is the intake valve is bent, which keeps it from closing completely. But when did it happen, it's
    been since May 2016 that the motor has seen anything over 5000 RPM. Since then I have been on another
    6 hour drive to the Lake of the Ozarks in September. When I parked it at the end of the 2016 summer in
    October, I had not noticed any changes in the engine behavior.

    Grumpy needs to get away from the kids and wife and move to Oklahoma, then this would be a fun problem
    to solve, just hope it doesn't cost too much !

    obviously its time too pull the head and inspect closely
  19. Indycars

    Indycars Administrator Staff Member

    You would agree then that 0.060 inches difference is considerably too much???

    I thought about one possible cause, that would be the valve keepers NOT completely seated.
    But no that can't be the problem if you look at the photo.

    Anything else I can check before getting serious about pulling the heads???

    If so then I better pull both heads, when I'm this close. Also I will be checking for signs of DETONATION,
    since this would be a good time to verify what I believe I've been to be hearing.

    WITH PRACTICE you can pull the heads and intake in well under 30-40 minutes,
    ..WITH PRACTICE even far less time with air tools

    you might want to pull a spark plug and use a flex micro cam to inspect inside the cylinder




    this is also a good inspection tool
