• I took some pics of my frankinstien engine build. Not done yet but gettin there.
  
  
  
  
  
  
  
  ARP studs, main bolts and rod bolts. Man I hope this is the way some of you have seald up the gasket to block part.
  
  
  
  
  
  I bought this AAZ head new and did some porting. Mostly cleaned up the castings and matched ported to the gaskets. Also peened around the precups. You can see how I capped off the extra oil return hole.
  
  
  
  
  The next thing to do is drill and tap the head for the valve cover.
  What do you think.

• Very nicely done!  Where did you score that valve cover?
  
  Edit: Which valve cover will you be using with the 1.9 head.  That's a regular old 8v cover.  :?

• Its not mine, its my bro's. He had it laying around the shop.

• That engine is never gonna work.... Dump some dirty old oil all over it, then it will be fine  :lol:

  hear hear!
  
  I have a new head too but my block is grimy as frick. Thats a nice green you have there.
  
  Sweet Sauce man.

• hmmm did you put the mechanical lifters into that head?  i don't see how it can work properly with hydraulic lifters.
  
  looking nice though!

  It will work mostly fine with hydraulic(BTW thats the proper way to spell that) lifters but its going to make a hell of a mess when coolant and oil is leaking from that hole.
  
  I have 2 Mechanical lifter engines and one Hydro. Im not even going to try to put a multilayer head gasket on the Mech engines. I might buy the super expensive one the 53 willys used.

• Here's my 1.9 head on a 1.6 mechanical block project:
  
  http://www.vwdiesel.net/forum/index.php?topic=15780.0
  
  Topics include: porting, converting to mechanical, reaming guides, valve options, using a non-1.9 valve cover, metal head gasket, etc
  
  
  
  
  I pulled the head again so I can remove some aluminum ridges at the base of the cam towers so I don't have to pull the cam to change the valve lash shims.

  i thought that the hydraulic engines required the extra drain hole... mech engines have way more oil pressure at the head because they don't need it... i would assume that the extra oil would pool in the head and drain slower?  or am i missing something?
  
  you can buy the mechanical lifters to convert a 1.9 head into mech though...

• One question about the extra oil and higher oil presure. I've done alot of reading and I thought that when you upgrade your oil pump to the 36mm one you get better oil presure. Well isn't that pump for the hydro engines, and we're putting that on our mech. engines? More oil presure but one drain.
  I'm just blocking the extra drain due to the block doesn't have the drain hole.
  The rubber plug on the block at the coolant passage is to keep eveything from cross contaminating. Like what Audi80/ MJF did.
  
  I have never done anything like this before, but have read alot about what others have done, and from what they have said, it works, regaurding the MLS headgasket to mechanical blocks.
  
  Did I missread something when the upgrade and conversion was done?

• There are two other oil drains at the outermost head bolts on the manifold side of the head.
• #11 by Powered by Spearco on 27 Jan, 2009 22:03
• Yeah there sure is.
• #12 by zukgod1 on 28 Jan, 2009 07:48
• It will be just fine.
  
  I did it long ago and works just fine.
  
  I'll be in PDX in June on vaca. I'll drop ya a line before I take off, maybe I can stop in and say hi..

• Sounds great.
  
  Thanks for the replies.

  There's no need for the extra oil drain.  In the vanagon the engine is tipped to 50° and works fine with hyd lifters.  I guarantee that no oil drains down either of the front drains.  In order to do so, the valve area would be completely submerged.   :shock:

  sounds good then
