The later chains are different.. if you drop the timing covers off, you'll see that the early OBD1's are a twin top chain and the later type ones are only a single chain..

Unfortunately, it does mean that they aren't interchangeable

There are also differences in the top tensioner, as the early ones are oil fed and you have to bleed then before fitting.

Which is the better system single timing chain(later version) or twin timing chains(early type)?Which is the better top tensional early type oil feed or the later type?If the later system is better is it posible for the early vr6 12v to improve tothe later timing chain system?

Thank You.
