The car no longer burns oil, compression is up in 3 of 4 cylinders. Did a leak down test and the results were astonishing (above 80%). This restore stuff filled in the scratches and saved the engine. The crankcase hose no longer whistles when you rev the engine, and the crankcase pressure is back to normal. One shop quoted me $3500 for a junkyard engine to fix a car valued under $1,000.
The Restore stuff does what it claims by filling in scratches with lead, copper and other fillers. Some research on this stuff indicates to use a small amount (5%) as maintenance because it wears off.
That stuff didn't fix anything. What it did was prolong death,which is exactly what it's supposed to do.
I used it in high school. Plugged my oil filter,staved the cam of oil and rounded off the lobes. When I saw the filter media after dissection(looking for metal bits,which we found)the folds once stretched out left 1/16 if residue,and the media was completely covered. If oil made it past that I applaud the oil pump for its valiant effort.
Don't use this stuff in an engine you want to keep.
