Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
I thought ole mate was trying to turn the motor off that bolt with the plugs in . Try it and see if it doesnt break how do you think I know its easy to break? Anyways all I actually suggested was to advance it up further to see if would run any better I didn't see any point in picking on valves at that time and was wondering why ole mate needed to turn it over by hand at all?No it won't, I think you've misinterpreted. I didn't say anything about a spanner
Yeah, think this was me misunderstanding what @EYY meant. Thanks @the_boozer for stopping me before I sapped the bolt off and took a few knuckles with it!I thought ole mate was trying to turn the motor off that bolt with the plugs in.
Now I'm just curious, slap me if I've missed something.
You said this motors done about 50,000ks? Is that since new or rebuild?
If somethings been sitting 30years with God knows what oil in it you could have sludge issues or rust etc etc.
A sludged up sticky hydraulic lifter could give you vacuum issues for example
Could also be something simple but this thread could start getting interesting soon
