Question about 1990 Jeep Wrangler
I HAVE A PROBLEM WITH THE ENGINE BLOWING OIL OUT OF THE MOTOR. IT KEEPS BLOWING THE PCV VALVE OFF AND BLOWING OIL OUT OF THE BREATHER ON THE VALVE COVER. iT ALSO HAS BLOWN OIL INTO THE AIR INTAKE BOX. THE MOTOR IS A 2.5L 4 CYLINDER.
The oil blows out due to excessive crankcase pressure. more than likely a piston has a hole in it or it needs rings.
