ENGINE AND ENGINE COOLING:ENGINE
CAR DEVELOPED AN OIL LEAK, I THOUGHT IT WAS THE OIL PAN GASKET. TOOK IT TO A DEALERSHIP WHO CHANGED THE OILPAN GASKET. IT STILL LEAKED OIL, SO I REMOVED THE ENGINE. I DISCOVERED THAT THE BLOCK HAD A CRACK FROM THE CRANK SHAFT TO THE CAM SHAFT ON THE REAR OF THE ENGINE. I TRIED TO ALUMINUM WELD IT ONCE, BUT IT STILL LEAKED.
