I have a volvo 230b 4 cyl I don't know much about volvo's but I was wondering where to get a manual for it or where can I get as much information about it as possible? I have taken the head off and the oil pan and I found out that the piston walls are in good shape and crank and head turn out it looks fine but while im there I want to replace the rings and rod bearings. Is this model motor a good motor it has a non interferance head on it which is great if the timing belt snaps? Thanks for all information.
