03 Expy 4.6L
Hi All:
New to the boards and I have a question...well two questions.
First, with all the talk regarding the spark plug removal on the 5.4L, does this apply to my 4.6? It is a Triton...which I believe is the 3 valve.
Secondly...after this crappy brutal winter, I've developed a ticking noise. But instead of going away after the engine warms, like the posts I've read, it starts to tick after the engine has reached operating temps. Any ideas where I should start to look?
Thanks in advance!

Hello and welcome! To start with your question about spark plug removal: if it is a 3 valve the answer would be yes due to the way the heads are designed on these engines. The way to tell if you have a 3 valve is if you look at both valve covers on the top of them where the cam sprockets are there will be an electrical plug that controls the cam phasers.
As for your second question, use a hose as a stethoscope and listen around the valve covers and exhaust to see where the noise is coming from. You might have an exhaust leak. The way you describe it sounds more like cam phasers but lets not jump to conclusions yet.

Still be carefull to avoid stripping the threads in the head and use anti-seize when reinstalling.
Agree with Ford 05 on trying to determine ticking location to help determine issue. Bad lifter, vacuum leak, header issue, loose plug, rod knock?
