Hey guys,
Back from Ben's.
Good news, car is not going to explode. No pinging, was cold anyway, but he couldn't hear or feel anything not right with the engine. Said it drove really well.
Possible things to do would be rocker cover gaskets because oil leak, maybe full auto tranny oil flush because some changes were a bit hard, maybe look at sway bar links.
He rattled the exhaust a little and heard a bit of a clanking noise, so that could be exhaust hitting a head shield, which might make the "pinging" noise which I said was coming from the right passenger door side.
So all up, good check out my Ben, car is ok, no need for engine swap, just look at fixing up a few thing.
Thanks Ben, great bloke
Really, a rattling zorst!!? Hahahaha
