Engine Mechanical problem
1991 Subaru Loyale 4 cyl Two Wheel Drive Automatic 145000 miles
Did right cylinder head job and replaced blown head gasket. Aligned timing according to alignment marks. Engine starts but shakes and stalls. Checked exhaust and replaced exhaust to head gaskets but right side pipe has a large rust hole in it. Can this cause the shake or should I look for something else? Also will that cause engine to stall?
