We think that the spark plug was loose and blew out of the head. He put another plug in and made it from down town to OLPH and it did it again. Now there are no threads left on the head for that plug. I have another head from a same year bus that I could put on. Is there a better way to fix this? Thanks in advance.

P.S.  whether you use your old head and fix it, or the used one, pay REAL CLOSE attention to the valves, guides, seats.  I'm just sayin.  you don't wanna be right back in there.

It is the passenger side that blew. I am going to pull the head and Travis said he would help me with work on it. Anything I need to do special to take it off or put it back on?

First thing to do is get all of the small children out of hearing range, Buy a 1/2 gallon of "Ole Barley Corn" and a buy a wrench and fly at it. Like Rick said I'm going to the garage and hug my Type-1

If you pull it down with the engine in there, you should get new pushrod tube seals,a valve cover gasket, intake/ exhaust gaskets.  the exhaust is the most fun to wrestle on and off.   just try not to disturb the piston cylinder sleeves.  leave them stuck to the block if you can. and stuff rags in everything while it's apart.  Just remember to take them out when you put everything back together.   :wink:

And don't laugh.  i've seen it happen.  and no, it was not me.   :lol:

I am just going to do the one side. So I guess I need to go by Mainly Foreign and tell them to give me about every gasket they have for this motor? Boy, this sounds like it is going to be fun.

and to complete the thought..... if it does happen, it gets really ugly.   :cry:

A blown up type 4 engine is a good first step to a type 1 conversion job.  IMO.... :wink:

They should torque to 25pds.   The square block between the rocker arms has a slot in them . The slot goes down. The wire clip short portion  snaps into that slot and the long portion lays down to help hold the push rod tube in. You may have to pull the long portion out a little with some long nose pliers to snap onto the tube.  Install the head with the proper shim between cyl. head and cyl. You can install the tubes after the heads are on .DO NOT use a sealer on the "O" rings for the push rod tubes.  Just put some oil on them to make it easy to slide the tubes in. You may have to twist the tubes to make them go in. Be careful there. I hope I haven't confused you to much :lol:
