Cheers Bob!

I'll do a bit of investigating. It's mainly the camshafts that are proving hard to get. Not sure about second hand ones as the lobes can get worn.

The rest of the stuff is gaskets, the right ones this time!

 

Good to meet you the other evening.

 

Cheers

The head is alright. The rocker cover that fits on the head has twin camshafts incorporated in it and is the problem as the camshafts are scored . Might be able to get the rocker cover complete, but the camshafts will need to be good.

Are these not machine matched to the head though, the cover that bolts the camshafts in?? Usually are.

 

Hard to picture it with no rocker cover on to imagine setup of cams etc

Don't know about that. I'll check with iveco tomorrow.

if they were not machine matched and some were slightly out / oval , too big or too small where the camshaft is then even if you do torque it back down and evenly it could crack / fracture / be loose etc

 

im positive they should be machine matched...

 

come on aspen arb chip in

Spoke to Iveco, and the rocker cover is not machine matched to the head.

Now looking for good used one..

If the valves have taken hammer then you will need to change the valve guides. Beware here as you need an 8.05mm reamer to provide enough thermal expansion clearance. If you don't the valves will fit but once run for a few miles the guides will snatch the stems and pop goes your weasel.

 

Don't ask how I know all this ....................... but it just so happens I have the reamer!!!

I stripped the valves out for the cylinder head and checked them all.

They were all OK, cleaned them up ground the valve seats and put them back in.

The only damage is to the rockers and the camshafts. Got some good used camshafts coming hopefully. 👍
