[QUOTE="dubbedup67, post: 590492, member: 12031"] In need of some help good people. On the way to Big Bang my 68 overheated the oil filler cap blew off and spewed oil everywhere ,blue smoke billowing and she was massively down on power.was running beautifully until midway down the M1. when trying to fathom out what to do at the services I'd limped to I noticed that there sounded like a rattle/knocking coming from cylinder 3/4 side at half throttle and up. Topped up oil after letting it cool down for an hour and still a rattle/knock. Dropped the oil today and checked the valves and this is where I need the help. There doesn't appear to be any metal in the oil,and there's no end float on the crank.so I don't think it's big end bearings gone. Popped the rockers off and noticed that one valve appeared to be open on cylinder 3,all the rest seemed level with each other. And one valve seemed open on i think cylinder 1. See pics. Are they supposed to be like this or is one/both of them stuck/ bent. Im a complete novice when it comes to engine internals [/QUOTE]
