Some of you guys might know my problem...atleast the major one,
my engine ran out of oil and started making this noise,






ever since that day, i drove my car to my autotech class and its just been sitting there, and waiting on a new engine...



NOW, my dads 01 Audi A6TT is leaking oil and makes the same noise[ when its low/nearly empty on oil
we add 3-4 quarts and the noise stops...

(dont worry about that car its going to the shop soon)

my question is,


if i do another oil change, and maybe add some 'lucus' (or oil thickener?) will be car be normal again?
Or atleast safe to drive?

it doesnt work that way. ill try to explain.

your oil pump provides pressure in the engine. oil passes through journal through the crankshaft to the rod bearings. a very thin layer of oil provides the lubrication between the crank surface and the bearing. when you have no oil then the oil barrier is gone and you have metal on metal contact and friction. thats VERY BAD! very soon after the bearing will bond with the crank and spin inside the rod journal. once that happens you will have metal shaving flying all throughout the system. the engine is a ticking time bomb. the rod is now bouncing around the crankshaft, thats the knocking sound you hear. the damage is done and its only going to get worse. changine the oil is not going to save you

do a search for my thread on rebuilding the 7A-FE. i have over 100 pictures showing these parts to give you an idea whats going on in there
