So I tried the club lexus boards and people just read and no replies. Hopefully someone here can help. A while back maybe 3 months ago my passenger side camshaft bolt broke after my car overheated and. The car ran barely when cold and would die when warm. I fixed the broken plastic water neck and started it worked fine, idled fine for 30 min. Drive it to auto zone to return some parts I didn't need and 2 miles away in the autozone parking lot it dies. As soon as I take off the pass side spark plug cover to check spark I see the cam gear is loose. I figure hmm...weird. I tow the car home break down that side and the gear falls off. So I buy a new (used) intake camshaft with pulley bolts and pickup. The journals are good and oem spec form a low mileage motor. So I put the cam in alining the 4 dots (I followed the diy on lextreme). Intall timing belt all marks are dead on spot. Put a brand new battery in and go to crank it and it doesn't start. Cranks but no fire....anyone have any ideas?
