Hi i have searched and searched and cant find an image or description of the timing mark on the pulley that all timing procedures that ive found speak of....
I have a 2000 xj, about to start her up after a complete rebuild, including the top and bottom of the engine. Cant get the timing right, can anyone help??
Also i have a pin hole on my fuel line before the fuel rail, can i patch it w something or should i replace? Thanks in advance!!!

Can't really help you on the Timing issues, but I will give my .02 on the fuel issue. I've heard a fair share of earlier model XJ's burning down in flames from leaking injectors and then fuel getting on that Exhaust Manifold, instantly igniting. It just doesn't seem worth it to me..but thats just me

Here's TDC:

And here's how to find it:

Setting Your 4.0 at #1 TDC
　

With #1 spark plug removed, turn the engine over clockwise using the 3/4" front crankshaft bolt. You will see the degree marks on your front cover. Mark the 0 with chalk or white-out.You will see the timing mark on the balancer. Mark it with chalk or white-out. While turning the engine over, put your finger/thumb over #1 spark plug hole. As the mark on the balancer approaches the marks on the front cover, if you are coming up on #1 TDC, pressure in the cylinder will push on your finger. If there's no pressure, you're at #6 TDC and need to crank the engine over until you see the marks coming together and you get pressure. Set the mark on the balancer to the 0 mark on the front cover.

"Marker piece" is part of the timing cover.............

Weird, I must have lost it when I was stripping the engine down... Probably just get a new cover....?

That is weird. the markings don't come of, they are part of the cast of the timing chain cover. Unless that year has something different,

Worse case scenario, don't get a new cover, You can stick a pencil or something in the spark plug hole to find where the piston is at the absolute top by rotating the crankshaft slightly back and forth (on the compression cycle) remember, the engine spins clockwise from the front.

Even if you are a little off the mark its ok. the ignition timing is not adjustable mechanically anyway. You can go from there. It will start and run fine.
