So i just did a stock motor swap on my 89 mustang 5.0 and everything is perfect except for the fact that there is a knocking somewhere in the tranny/bellhousing area. The knocking is mostly heard when first starting up the car then as i drive around for a while it goes away. but then it will come back. I think its clutch related beacuse if i put any pressure on the clutch, it goes away. but ive heard of problems like this with the pilot bearing(new). Do i need to just adjust the cable better?(i have a firewall adjuster and adjustable cable) or is the throwout bearing done?
