    How to fit a TD5 head.... Pt1

    Right then, lets put it back together. (with a couple of little extra jobs too)

    Firstly drop down to the dealer, and get some more parts:



    Now, remove the old exhaust manifold studs. if you havent got a set of stud extractors, you can use 2 nuts like here:



    All removed:



    New ones fitted:



    Now swap the little bypass hose on the NS of the block:



    Clean block:



    Place dowels in (here is a comparison picture of the plastic(old) and steel dowels:



    Now place headgasket on, and lower head into place carefully:



    Now oil the threads and under the heads of the new head bolts:



    Place the head bolts in gently (dont drop), and in 2 stages torque them to the manual specified settings (cant remember - will edit this later):



    Now make an angle gauge and mark a socket so you can tighten the head bolts to the required angle stages. these are 90degrees, then 180 degrees, then 45 degrees.

    As each stage of rotation was done I marked the head with a permenant marker so I knew which ones were done:



    Once they are all tight fit and tighten the nut and bolt at the front of the head: Now lift the cam pulley onto the shaft ensureing everything is lined up as it should be:



    Finger tighten the cam pulley bolts, then back them off 1/2 a turn.

    Then apply loctite 242 to cam chain guide, and refit:



    Then fit the cam chain tensioner and torque as required:



    Now tighten the cam pulley bolts:



    Now remove the locking pin for the camshaft

    Now fit the vacuum hose:



    Now refit the alternator bracket:



    Next, fit the exhaust manifold gasket, and then the exhasut manifold, with new nuts:



    Thats as far as I have got so far. carry on tonight.

    As mentioned previous, am very much enjoying your series on this project.

    Just a couple of questions:
    Looking at the block pic. I dont see any stud holes. Do the studs (only 12?) go down into what look like oil return ducts?
    The studs seem very long, what dia. thread. (look only 10mm.?)

    I have been wondering why the dowels so frequently fret on these engines, pehaps the amount of expansion/contraction of the alloy head could be the reason those few head studs (18 on 300tdi) stretch and allow the head to move and blow gaskets.

    Have often thought would I would like a td5, (did look seriously at one, that bung in front of the camwheel was leaking quite badly) but maybe one should stay with the old 300, at least I know her pretty well!

    Hi Llandro,

    The dowels are mainly an issue on the earlier <2002 engines as they are plastic. Later ones are steel.

    Yes there are 12 head studs, and they do go down to the tapped holes at the base of the larger holes in the head face.

    Tdi or Td5 is going to be down to personal preference, but I wouldnt have a 300 any more. I dont want this thread to turn into an argument on that please!!

    Not sure on length of studs. Will check tonight on the old ones.

    Sorry Pete.
    Didn't mean to divert/hijack, only contemplating aspects of the td5 engine I really know nothing about.
    I am ever curious re design features of all things mechanical (Mech.E in previous life!)

    pete,
    out of interest are your manifold bolts the standard 8mm? or have you gone the bigger 10mm as has been done by others.

    Well done Pete!

    Great, clean and meticulous job. Well documented also

    You'd be getting more and more confident and familiar with your landy now I dare say!

    On a side note, had a 2000 model 110 with 150K come in today with water consumption, cap leaking, overpressurising and intermittent heater operation...

    ...Do you want a job doing the head gasket on THAT one too?
