Tick, tick, tick getting worse

And despite what "some" might say, A gerotor pump WILL make a damn site more than 60psi... I know this because, I've personally been involved in designing transmissions and specifying gerotor pumps and they will make pressures in excess of 60psi.... And that's all I have to say on you "needing a new gauge"...

I have decided that I will pull the engine and get it on a stand so I can further investigate and pin the liners properly. I'm relocating to another town next month so it will have to wait until after we get settled in the new place.
My plan is to document everything and share it here. Keep a look out in the next month or so for updates.

My 03' has been ticking now for about a year or 5K miles. My lack of faith in the engine doesn't allow me to do what I would like with the Disco. I'm tired of listening to it and will be pulling the engine as early as this weekend. I have a spare block from my 04' that has cylinders a few thou out of round and was replaced by a turner block, but should work just fine.
I'll be looking at the valve train in detail and of course looking for marking on the head gasket firing ring. I also will post my findings for all to see.
If I didn't like this kind of stuff owning these things would not be fun.

I have a 2004 Discovery with just over 104,000 miles. Purchased in March of 2011 with 78,000 miles. I believe I am the third owner. It was solid when I bought it with no abnormal engine noises. I started noticing a ticking somewhere around 90,000. After researching several sites, I decided to go with the Purolator L40316 filter and Rotella T 15W-40 oil hoping it would make the tick go away. It did not. I wish I had checked my oil pressures prior to switching to the Purolator filter but didn't.
The ticking seems to be getting worse and I have started pricing new cams and lifters. I spoke to Mark at D&D Fabrications and he priced a stage 2 cam kit that I am in the process of funding (I can send you my PayPal information if anyone is interested in sponsoring the upgrade
). In preparation for the new cam and because the ticking seems to have gotten louder, I measured my oil pressure this evening.
My cold readings were 54 psi at idle and 58 psi at 2K rpm. Warm readings were 26 psi at idle and 51 psi at 2K rpm. Do these reading look right to those of you who have done the Purolator L40316 filter upgrade? Any advice on what i should look for as I replace the cam?

Stop leak won't help in many instances, becuase the block has not cracked yet and there is no coolant flow behind the liner. The tick is from it hitting the fire ring on the head gasket. In addition to pinning, saw a shade tree reference a long time back on another site about crimping the liner so it would not move, not sure if this could be done from the bottom in the truck. What is the American 2 part item you reference?

Factory liners are extrmely brittle, and not in any way ductile or able to be "crimped". It would have been a nice fix for sure, but sadly it is one that will never work.

Does anyone know what whomever built these engines did wrong to make this issue seem to be very common on the 4.6 blocks? This engine has been around forever so I'm just curious what the heck changed to make this happen.
