1st of all hello to everyone,i am a frequent viewing but 1st time poster
i have a yr 2000 318 ci
it needs your help!!!!
in the morning after a long night in the garage,,when i start the car,,it sounds like the 4 cylinder 318 i that it should be,,sounds just dandy
after the oil has heated a bit,it gets a bit rattly..
if i turn off the car and wait 10,20,30 40 minutes etc,,,,,when i re start it,,it rattles like a diesel...all from the top end,,,,but not like a click,,like an injector
it rattles like the hydraulic tappets....
if i allow the car to cool for a few hrs,,when i re start it,,it sounds ok again..
i have re placed the oil 4 times in the 3 mnths since i bought it...
i have put in 0w 30..5w 30...15w 50[to try a thick oil]
and have now put back in 5w30...all being castrol or mobil synthetic oil
by replacing the oil,it all sounds ok for a few hrs,,but then it is back to normal
a rattle on start up...
the car itself goes like a dream looks like a dream
what should i do???
get new hydraulic lifters?? or do i need a whole rebuild? the cam sounds ok,,,the is no constant ticking sound when driving ,,,just a tappety sound at low tick over,,when i drive it,,it has all but gone,,maybe a small ticking,,only to my ears
