My 5.4 3V is getting the startup rattle. I’m planning on ordering new OEM camphasers, chains, guides, tensioners and cleaning out the oil pan plus pickup. Is there any real need to replace the oem oil pump? I’m not seeing it as very important since my primary oil loss is coming from the leaky tensioner and not the pump.
My 5.4 does not knock or tick, it does not make any noise from under the valve covers and runs good and quiet. However lately if it sits overnight or for hours on end for about 1 second it will make noise and stop upon startup. I watched Makulocos video and he says not to ignore this long term as it means a tensioner gasket is failing.
