oil type and oil pump

[fixkick]

the engine is cleaned 2 ways
at rebuild time.
and each oil /filter changes.
doing otherwise is asking for huge problems. why do that?
as they say, "be careful what you wish for, you might get it... and.....?"

why would you want to break up , that nasty gritty stuff, seen on all rebuilds, and let it loose in the engine. running.????????????????
no water cooled engine is noisy, air cool is.
there is some small valve noises.
exhaust port noise.(muted by cast iron headers)
not at all , it sounds just like all, over-head cam engines, for sure 1.6L same,
listen to other cars,with hood up. 1.6 to 2L
then go back to yours, and use a stethoscope a $5 tool an find all sources of noise there.
might be a loose bracket there, (inside noises, can be detected over outside) easy
