Hello All,
Bit of a head scratcher. Head all done and being bolted back on, timing chains were locked etc, previous mark on pulley wheel (tipex) actually lines up with number 4 being top dead centre but lines up on camshaft, the pulley wheel has been cleaned, and the original manufacturers Mark for tdc found and that is at tdc for number one but the camshaft is not lining up by a large amount. Chains previously put on incorrectly? But car ran fine since I’ve owned it, 15,000 miles.
Hope this makes sense!!
