Technical help please with camshaft alignment 03 2.0 16v jtd

[wheelspin]

Hello all, i am new to the forum. I have a 2003 fiat ulysse 2 litre 16v jtd that i bought with a broken cambelt. I have stripped the head off and checked the pistons which were in good order, no valves were bent so fitted new head gasket and replaced 6 broken followers.
I have autodata s/ware which shows the timing procedures for the cambelt but it doesn't show the timing relationship between the 2 camshafts ( 1 camshaft ( exhaust ) driven by the cambelt, the inlet camshaft is driven by a chain from the exhaust camshaft ) it is the setting up of the 2 camshaft on the chain that i am struggling with.
I bought a disc off ebay which shows a timing mark on the front of the sprocket on the inlet camshaft which is timed at 12 o'clock when the other camshaft is locked with an 8mm pin. On inspection of my inlet camshaft it is not the same, there is no timing mark on the front of the sprocket but there are 3 dots on the back of the sprocket. Can someone please advise and if possible post a diagram ?

Thankyou in advance

Andy

i had exactly the same problem and can't remember the relationship of the dots however they are relevant , i basically set the camshaft up as a mirror image of the one with the locating dowel and then i think one dot was vertical and the other 2 were to the right also i would replace all the rockers as on mine some had hairline fractures !!
can you tell me how the sprocket is fixed on the cam , has it got a key or something ?

Hi, thanks for the reply. I Have sorted it today. There is an arrow on the outside of the sprocket which was so faint that i couldn't see it until today when the sun was blazing !
As for the fixing of the sprocket to the shaft, i would say that it is part of the shaft and the other side has a key way on it similar to a woodruf key except the key is part of the sprocket and not seperate.
Had fun removing the injectors for which i ended up making a tool to extract them. I managed to save 3 out of 4 which is extremely good going according to other mechanics i have spoken to. I was told that i would have to smash the rocker cover/inlet manifold and remove the head with the inectors still in place then have them machined out and have to replace all 4.
I been told to patent the tool and start selling them because this problem exists throughout a whole range of cars and vans. I have never come across it before but not really worked on diesel engines that much.
