I have a 1968 firebird 350 with the yj engine code. YJ is the code for the 68 engine. It runs but I opened the timing cover and changed the oil pan gasket and found nylon timing gear parts in the oil pan. So I started to look at the timing gear marks and found that the cam gear was at 12:00 and the crank was at 12:00 The car was always hard to start.
The manual says that the cam gear sould be at 6:00 and the crank at 12:00 ( dots closest to gether ).
Now in 1971---1974 (maybe it's 1979 ---1981) 12:00 and 12:00 is right but my engine code says that my engine block is 1968 witch sould be at 6:00 and 12:00.
My real question is will an engine run if the timing marks are off 180 degeas? or maybe someone put the timing gears from a 1979 --- 1981 engine on my car?
I thank you for any help John H ]]> Pontiac rccat http://www.automotiveforums.com/vbulletin/showthread.php?t=969532
