Here is some
information kindly contributed by Colin Jenkinson of Australia:
Just a note
of caution on the V6 3.4 Litre engines I have seen offered on your site.
I have just finished fitting one of these to my Taimar here in Australia,
here is what I found with the crate engine supplied to me.
The engine was not new but remanufactured with 60 thou pistons
I had the engine balanced to match the old flywheel and pulley.
The engine had been hot tested (started and run) unfortunately they did
not pre lube it correctly and scored the rockers and shafts.
Rockers are available from South Africa, Rocker shafts appear to no longer
The engine builder who balanced the engine said the rocker tips look as
though they had done 100 thousand kilometres and not been refaced.
The oil pump had imperial bolts screwed into metric treads for the oil
pickup, I ended up installing a new oil pump to repair the damage.
The exhaust port bolt holes are spaced further apart than the essex engine
a new header plate is needed or new exhaust is required.
a new JP exhaust system to fit, nicely ceramic coated as well.
I have a
digital file for a laser cutting machine to cut new plates if anyone needs
The front pulley retaining bolt is metric not imperial as in the Essex
Otherwise it will bolt straight in!
it has a stroked crank as standard but I did not check the stroke on my
3.4 litre was cast into the original rocker cover so I have no reason
to doubt it.
I also understand a 3.0 litre version was made so I guess it is possible
they swapped cranks shafts around.
I understand Burtons and others were selling the cranks from South Africa
then modifying Essex motors but I believe supply has dried up.
