So when I first got the truck . The steel oil pump drive gear and oil pump had no teeth . skip time. So installed new steel drive gear and oil pump. now after 300 miles the same problem. May be my timing cover is worped or out of alignment. I will be taking apart spare motor to inspect parts supply. Will a civy 230 timing cover gasket work? maybe gear aligment is off? just put my detroit no spin locker in today and this happens. long ride home adjusting timing then moving wires on cap every time it jumped time. made it 15 miles and skip at least 6 teeth total. Then strap towed the other 15 miles. I guess I need AAA. Any body have a used bronze OE gear. This motor has been apart before maybe dowl pin alignment off?? Any input is helpful .Thanks
