How much are you being charged for the part? My Eper says its £4.15 inc.
VAT – which is six times what I paid. I’m not sure how to call up a picture of
the part, and I can’t find the part TBH.
My filing system is about 5 months deep so I have little chance of finding it
for you.

Those bolts hold the Camshaft in place.

I’m not so sure TBH
I

OK I think its better to remove the distributor completely and take the
opportunity to check vacuum advance. Steps E and F are optional, but good
practice.
First of all, allow a good afternoon for the job – You don’t want to rush to
finish as things easily go wrong. Start early if your working outdoors - you
don’t want to run out of light. – then again – I took loads of pictures

This is exactly how I would do It,
Key
1 – cam Cover
2 – Cylinder head to distributor join
3 – Distributor
4 – distributor cap
5 – distributor cap retention clip (lower one not in view)
6 – vacuum advance diaphragm
7 – vacuum advance pipe
8 – distributor electrical connector block
9 – Distributor mountain nut and washer – (lower one not in view)
A. with ignition off at all times!!! And engine cold Spray nut and
washer 9 with WD40 or other penetrating fluid. Do the lower one too. Put a rag
below 2 as there should be a small oil leak when you remove 3.
B. Scribe a couple of scratches across area 2. – This will help you refit the
distributor with the correct angle essential for the timing.
C. Unclip 5. and rest 4. out of the way, with all wires connected.
D. Note which way the rotor arm is pointing, but leave in place. It won’t
necessarily be pointing the same way as mine pictured BTW.
E. Unplug 8.
F. Follow pipe 7. to the back of the engine and disconnect. Note the pipe is
fixed at a right angle and simply pulls off.
Clean the end of the pipe, and try blowing down it gently – less effort then
blowing up a balloon. You should be able to blow a tiny amount, then no more.
If this is the case the vacuum advance pipe and diaphragm are good.
If you can blow continuously, inspect the pipe for holes. Try removing the
other end, blocking it and blowing again. If you can still blow, the pipe
needs replacing. Try sucking too, if the pipe collapses it will also need
replacing.
If the pipe is good, clean the outside as any oil on it will eat at the pipe
and shorten its life.
Hmm it the pipe is good, but no resistance when connected to 6, 6 will need
replacing. There is a chance both 6 and 7 could be bad, but your not that
unlucky are you?
G. Have the rag ready, loosen nut 9, and the lower one about a turn, twit the
distributor to break the seal, then remove the lower nut, put the nut and
washer safe, hold the distributor 3 and remove the upper nut (put safe too).
Twist 3 and should come away in your hand. pit it somewhere safe and clean,
and turn your attention to the leaking oil.
Key2
1-0 – Coolant pipe on thermostat
2-0 - Cylinder head to distributor join
H. Don’t let oil drip onto the coolant pipe below – if it does – clean it off.
I moved the rags for this picture BTW.
If there is no oil leek – this could mean the cam is running dry, perhaps due
to a blocked oil pipe, which will need further investigation. It’s a separate
job, which doesn’t need distributor off, and will need at least a cam cover
gasket.
H. Cleans the old o-ring gasket off face 1-2. I used WD40, sprayed onto a rag
to avoid getting any inside the cam. – If there are any stubborn bits I’d say
don’t scrape off with anything metal as scratching this face will affect the
future seal. If any bits fall inside the cam hole, fish them out, as they
won’t do any good in there.
I. Blue Peter time – make 2-1 look like 2-2, using same method as in H.
J. Check inside the distributor for oil. – If you see any –
check here
http://www.fiatforum.com/showthread.php?t=24730- as the distributor inner
seal needs replacing. My local FIAT dealer couldn’t supply the part so I
haven’t done it yet. Mine were both OK, but I was going to do them both on the
spare distributor. I’m not sure if the distributor will need dismantling like
this. if it does, make sure all the components go back in the same order.
K. Fit the new O-ring to the clean distributor – yes it will go on
it
sits in the grove. Make sure it isn’t twisted as it will probably compromise
the seal. I fitted the gasket dry in that I didn’t lubricate it.
L. Now your ready to refit the distributor. Twist the rotor arm back to the
original position. It can go back 180 degrees the wrong way, or the right way.
M. Marry the distributor to face, may need the distributor body and / or rotor
arm twisting, but it will be firmer than when you removed it due to the new
O-ring gasket.
N. Now align the scribed marks from B., replace the washers and nuts 9 – don’t
over tighten them (hard to explain how tight TBH
).
O. Replace both ends of 7, plug in 8, refit 4, remove your rags, clean where
old oil leak ran down bell house, check for spare parts that should have been
refitted
and
start her up.
Take a short drive and check for leaks. – check after a day or too and you
should be OK. And not see
http://www.fiatforum.com/attachment.php?attachmentid=4618 - but it the
What you reckon Alex, Chas, whoever is still reading
–
have I missed anything.
That’s a long post – eat your hart out Mr gs and Mr 45S LOL.
Not sure If I’ve clarified or confused things TBH.
