1.6 td, head swap. na/td and solid/hydraulic

[Bo Gunnar]

I have a 1.6Td that needs a new head. I have learnt a lot on this subj. in this forum, but have I got it right? My engine is a CY (solid, 12mm bolts).

Are following statements correct:

  Na/ Td. A na head (12mm bolts) will fit. If  I am lucky valves and seat are same as Td. If not I risk to burn these (you never knew whats in a scrap head).

  Solid/ hydraulic. Plug and flaten the second drainhole in head.
Hydraulic lifters bleeds very little oil so I am not worried about the oilpump, but will the lifters be fed with oil properly? Can the second oildrainhole be plugged without problem?

i think you need to run the bigger oil pump (if the motor doesnt already have the 36mm gear one) as hydraulic lifter engines do use more oil psi.  mech engines tend to have higher oil psi.

you only need to block the hole on the block when using a non mech gasket (adapding the 1.9 stronger metal head gasket to a mechanical lifter 1.6 engine).  i doubt you need to block the oil drain as its a good idea to have with a hydraulic head (especially with the extra oil flow)

i'm not sure but i think vw started using their TD parts on N/A stuff after a certain year to cut costs down... not sure when though.  generally speaking TD stuff can withstand higher temps.  so no guarantee on how the N/A stuff will hold up depending on whether or not you're running stock TD specs.  

if the block is 12mm and the head is 12mm its pretty safe to say that it will work.

I think he was referring to the extra oil drain in the head (front) the second smaller drain hole.

If he is using a hydro head on a sold lifter block that hole will need to be plugged.

I COMPLETELY agree with jtanguay on the larger oil pump.
They just arnt that much coin and not hard to change either.

u don't need to change the pump, early, hydro motors had the same pump as the solid lifters, but like it was said, for the price and how easy they are to change, why not just do it.

Thanks for the comments. What is a 36mm pump? Pump gears or rotor is 36mm wide? No problem to get scrapped vw dieselengines here in sweden as the bodies rust away. Only problem is crack to the prechamber.
Its not so easy for me to change the pump as I run the engine in a old volvo 145 (we have no dieseltax on 30 year old cars) so I cant just drop the oilpan beacause of the front axle beam--but that is my problem.
