I bought a perfectly running, one owner, immaculate and low k's (120,000kms) 318i until I changed the oil...
I changed the thick black oil and filter to a fresh 15/40 Valvoline Synthetic(as per specs), which seemed much thinner (just my observation).
I now have a VERY loud, mechanical, non-lubed tick from ONE of the lifters.
It stays like this from cold, even when at running temperature. After 15mins of driving, it goes - but then intermittently comes back just as loud?
Today I started it and it was quiet, until I got to the top of the street and there it was again! (It's so loud that people look around).
So, I bought some cheap "lifter-noise-stopper-crappy-whatsit" and after 500K's, no change. So I went back and bought the stuff that was 3 x the price - no different
I don't want to drop the oil, try some more, try some more... I don't want to replace the lifter really either.
It can work out very expensive this "guessing the oil viscosity" game and I know there are lots of opinions on it too!
How can it be the lifter if it was fine before the oil? I don't believe in coincidences.
IS the oil wrong?
Fast "revving" or holding revs from cold doesn't stop it. It DOES stop it once the engine is warm though?
I read in a forum that to drain the oil properly, I should leave it 30 mins, which I did (never have before) and this I what I think caused it personally, but how to fix?
ANY help on this would be very much appreciated!
