So after my oil pressure warning light, to an oil pick up pipe change, to then another oil pressure light, to a pressure test which came out totally perfect. Im left with a terrible rattle which the mechanic spotted for me but i didnt have the money to investigate it more. Soo about the noise. -> Its only there when the engine is cold, and will dissapear at a random time after driving a bit. Within this time is when the oil pressure light may appear. -> I can just feel it in the clutch pedal when depressed by say an inch. -> It sounds like its coming from somewhere around behind the cam follower and within the next 2 spark plug to the left area of the engine https://www.youtube.com/watch?v=Fp4dwsGge54 I was trying to feel for it and you can feel it just. did the low oil pressure from the pick up being blocked cause the chain to stretch? Does the Tentioner reset after engine off/cold? Thanks for the help. JJ.
