• 2000tdi bottom end rebuilt to use with a 1.6 head? by Mk2Fanatic on 28 Aug, 2006 20:15
• I've got access to a 1.9l 2003 ALH montor that has 113000km when a valve was dropped on cylinder 4.  Needless to say the ensuing catastrophic engine damage has resulted in a customer getting a replacement motor installed through our shop and me be the owner of the $5000 anchor.  I've pulled the head as it's pretty much junk.  Piston 4 is also useless, but the bore was luckily not damaged( you can still see the factory honing marks in the bores).  The crank still spins freely, although I suspect the no4 rod might be bent(I'll know tomorrow).
  
  Being a VW only repair shop in Windsor Ontario, I've got access to quite a few engines.  We have a couple 1.6 NA and TD engines.  I'm wondering if either a 1.6/1.9 head and matching IP can be bolted on and used on the TDI bottom end.  If I replace the 4th piston and possibly the rod can the 1.6 head play nice with the tdi bottom end and actally work properly?

• There's probably going to be a lot of problems using it.  I would say that you will probably need 1.9 crank + rods + pistons + 1.9 head.  All AAZ.  You could fit a 1.6 head on a 1.9... but its not going to allow the motor to breathe the way it was meant to.
  
  Or... find a nice TDI head and get a TDI mech pump  
  
  
  ... Wonder how that valve broke inside the cylinder?  That has got to be some super bad luck, or VW's quality control isn't doing their job right.

• The short answer here is no. No IDI head that I know of will work on there so that engine must stay with direct injection. So, either get another head, piston, and rod or use the engine for parts.

• What about using the tdi block, 1.9 idi pistons/rods and an idi head?

• An ALH engine has different passages between the head and the block. It's not like the AHU/1Z where they shared the same block between the IDI and the TDI with the main difference being the crank sensor.

• Mk2Fanatic,
  
  what kind of shape is the camshaft in? I am interested in the whole junk head for parts that I am lacking on my TDI head.
  
  Let me know what you want for it if the cam is good.
  Thanks
  Justin

• vwmike, do you know if the cam from Mk2Fanatic's head will work in the earlier TDI heads? if so I want to buy Mk2Fanatic's head and cam and everything for parts
  
  later
