Hi,

I have removed the passenger side valve cover, which is the side where the #4 spark plug appears to be carbon fouled.....I can't seem to find anything that looks bad, although the #4 ball studs appear slightly lower than those of the other cylinders.....can someone give me an exact link or thread that describes how to determine if a ball stud is bad ?

I also checked the timing chain using the procedure outlined in "http://www.peachparts.com/Wikka/M117TimingChain". I tried to line up the cam marks as good as possible....it was at approx. 2-3 degrees to the right of zero. One thing I noticed, when turning the crank shaft, sometimes the cam/timing chain didn't move right away as I turned the crankshaft....is this normal ? It was as if there was slop in the chain or something. I also noticed that depending on where I rotated the camshaft, sometimes I could lift the chain up & it appeared loose & other times it appeared tight....just wondering if this is all normal.

Thanks,

Brian
