<VV> Re: dipstick tube o-ring?

[Ray Rodriguez]

Understood, that is what I was beginning to expect.  I have the shroud seal included in my kit.  I believe my tube was leaking at its base, where it is pressed into the case... I guess I will just goo it up with high temp RTV and press it back in.. I thought there was an o-ring there.

    I found the answer to why I have a smiley face on my #1 piston top....  The "lock ring" or "retainer clip" is missing off one of the lifters.  The lifters and cam are in new condition so I hate to install a new set but I dont know what brand or type the lifters are so I cant very well replace just the one.  I'm hoping to find a way to just get the clip and reinstall it.  I also checked the pushrods etc on that cylinder and found no other signs of damage.

  Ray - You easily replace just the one lifter. If the old face looks like new, the new face will look the same.
    I pulled the oil dipstick tube out because it had apparently been leaking... is there an o-ring or other type of gasket for the dipstick?  I have the clarks complete engine gasket set but its hard to figure out what goes where... I have the chassis shop manual and assembly manual but have a hard time finding what I'm looking for.. couldnt find the dipstick tube in either one.

    What is the best way to prevent dipstick tube leaks?



  The only gasket for the dipstick on a late model motor is up inside the "shroud" portion of the dipstick, the part that slides down over the tube at final engagement. It is sort of "tube" shaped, since it captures the tube as the dipstick locks into place. I don't know if that piece is available individually. It is often cracked/broken/missing on our older cars. That location is a very convenient place for leaks. (Convenient for the motor, not for us.) Crankcase pressure can also force oil up the tube. For racing, many people remove the dipstick and cap off the end of the tube with a hose, a bolt and two screws. It makes checking the oil a pain, but . . .
