    Thanks for the offer Grantus. Happy to say so far T3 folk are just as generous as T2 types (whoops have I started a war?:rolleyes:)

    I am assuming after all the thousands of heat cycles the plastic thermo housing can warp. Not surprised to hear go westy made a metal one.

    The housing here, was working fine when it was pulled - only replaced to save doing it if it ever failed down the track.

    About to do the same, & the plastic “Christmas Tree” coolant distribution tower, with a Stainless Steel one on the SC next service. ;)

    Won't start

    Borat Hemsworth is now all back in one
    piece... well Just gotta connect up the muffler. I had better do that so as not to get a 2nd warning letter from the council:oops:.

    But I spent a few hours and i have not got him to start yet. I have good fuel pressure 35 to 40 psi, spilt a bit too to prove it.
    I also have good spark but only checked one cylinder so far.
    4 new spark plugs installed. New dizzy.
    What do you think next step is?
    Check that injectors are firing? Put a node light on at injector connector?

    Earth lead connected between the block and the chassis?

    Is the dizzy in the correct way? - Easy to fit it 180 degrees out

    Yes I have that copper earth braid connected from engine to chassis.

    Good point about dizzy 180.
    I read the book and I thought they meant about the distributor drive shaft.
    I had a look at the bottom of the dizzy and its slot looked slightly offset, as if not possible to put in the wrong way.

    But I better have another look tomorrow.

    You said new dizzy, could the timing be way off. Did you set it up as described in the Haynes. Check all the obvious items, is the air flow meter plug connected

    Yes new dizzy from JK. Really hard to push in due to new o ring. Seems tight but took cap off and cranking engine rotates nicely.
    I followed haynes, but think i better look up bentley

    I am still a little confused, is it possible to install the dizzy 180 out? Or do they mean the distributor drive shaft 180 out?

    Having no 1 cylinder at TDC is the rotor pointing to the correct location as per the Haynes if not leave at TDC on no 1 and remove dizzy and rotate the rotor till you can set it up to point at correct location. Bit vague as cant remember where it needs to point but the Haynes tells you. I have used that manual to set up a dizzy with success.

    Hi Barry

    Yes I that is the one. The markings did look funny to me, but I tried moving the leads around forgetting about the markings and followed the ignition order 1432.
    I will have another go this arvo, but I want to rule one thing out. Is it possible to put the dizzy in 180 out?
    I cant remember but I think it was possible on my son's 71 but this new dizzy the bottom slot looks asymmetrial and not possible to put in wrong.
    I have read it is possible to put the distributor drive in 180 out.
    Like to here from someone who is is 100% certain.
    I guess I could try installing the leads in a way to cope with being 180 out and see if it starts.

    It is possible to put it in 180 deg out if there is a fair bit of play in the dissy cog.
    Worth checking.

    Progess
    Ran for 10 seconds
    Bazza was right, the dizzy cap markings were wrong I disregarded them.
    I rotated the pulley with tdc Mark at 12pm . Then ensured cylinder 1 was at tdc with poky screwdriver trick.
    Then made sure the rotor cap was pointed towards dizzy spark plug 1 lead.

    Presto it runs a bit

    Do you have plenty of fuel in it. If its low on fuel and the rear raised could starve but you are a step closer :)

    Yep keep plodding, 1 step closer.

    I think I have about 20 litres, gauge not worky, but regardless i have installed a fuel pressure gauge and I have a strong 35 to 40 psi on the rail.

    How to re build a T3 via the internet......:D:D:D


    My turn........ if it ran for 10 seconds, that’s about enough prime pressure when ignition turned on, from the fuel pump. :rolleyes:

    Does the pump only prime, but not work after that? o_O

    Yep I keep learning, kc, utube, vw samba forums. Even though grade 7 was the hardest 4 years of my life:D

    No even after borat motor stops , I still see 35 psi on the gauge so fuel supply is good. I think i need to keep tweaking this new dizzy timing. I am a little concerned i don't understand this dizzy , the cap seems to rotate around independent of the body a fair bit.
    I see a tdc Mark on the main pulley but should there be another one for 30 degrees at high revs?

    The cap shouldnt move is the rotor firmly seated

    It shouldnt move, loosen the nut holding the dizzi in, I mean the one on the block and make sure the shaft is well & truly seated. It can feel seated but as you said its tight with a new O ring on the shaft. Did you put some oil on the O ring
