Sorry Dan - not sure how I missed this. Thanks very much for offering to look this up. My engine is the 1993 2300cc 5-cylinder version. Grateful for any guidance here.
Also, do you know whether it is possible to purchase camshaft holders? I've attached a picture of what I presume is the camshaft as well as the aluminium holders - 4 in total, two of which have snapped. My mechanic can't find them anywhere. Maybe this first image tells you whether the bolts for the cylinder head can be accessed without first removing the cam? Thanks, Andrew
