DZ headbolts

[John Ferrell]

MessageLast I heard Clarence Lee does not do email.
Current info is always in the RCM Magazine Classifieds. It has been a couple of years since I needed the service but as I recall it was a YS91AC. That engine has the head integral to the cylinder and the charge was $12, including postage. 

He does not want the whole engine, just the head.

He also has a repair for damaged YS exhaust threads. However, it does add an insert that may require a rework of the header geometry.

  Hey Bryan....I got into this once before and found out that the thread of the plug is 1/4 32 and is unavailable from Helicoil unless special ordered. That is a non-standard size.
  Clarence Lee offers this service and is priced reasonable. I think he still advertises in RCM or you can send him an email.

    I need a Head for a YS 1.40 fz or L for a friend 
    if someone has one they would let go cheap 
    also does any one know if they make repair helicoil kits for these motors for striped glow plugs?

      Someone posted a problem with loose head bolts on their DZ a few days ago.  Mine did the same .  It started 6 or so flights ago, and terminated this evening with a blown head gasket.  I should have paid attention and checked mine before. Thought I'd post this for anyone who thinks, oh well theres probably only one engine like that and mine is just fine, maybe not.
