Chrysler Repair/'04 Pacifica cylinder head removal


I'm working on a 04 Pacifica that broke the timing belt. I have bent valves in 3 cylinders. I'm trying to remove the heads so I can assess piston condition. I believe I have to remove the entire timing belt cover to remove the heads. I have all the bolts out of the cover as well as the water pump. The crank pulley is the only thing still attached. The cover is still solid. I can't figure out what I'm missing to remove this cover. Can you help?

ANSWER: Hi Brisco,
Which size engine do you have, 3.5 or 3.8? There are many steps involved if it is the 3.5 and it would be best if I copied that and attached them to an email I would send to you directly. If you want them, tell me your email address but don't use the @ symbol, instead use "at" or the address will be automatically erased. I can instead send the 3.8 instruction if you have that engine.

I have the 3.5l.  I figured out how to remove the heads.  I would still like to remove the Timing cover that bolts to the engine so I can replace the seals on the back side.  I think I have everything loose.  It looks like a two piece cover.  I was hoping I could pull just the top portion off.  
Also, this engine has 202k miles on it.  Inside the engine looks very clean.  I have 3 cylinders where valves contacted the piston.  No piston damage.  I'm considering replacing and reseating the valves in those cylinders and checking to see if any others are leaking by the valve.  Would you be comfortable with that repair?

ANSWER: Hi Brisco,
I will send the three pages about the timing belt cover removals. I have to admit no experience with remediating this situation but what you plan seems appropriate. Thanks for the rating/nomination/kind remarks.

QUESTION: Thank you and you're welcome.
Would you see any reason to do anything with the valves that are still sealing well?  With 202k miles I want to be thorough but don't want to spend money I don't have to.

If by inspection of the other valves to be sure they didn't "interfere", or by a previous to the belt-break you happen to have compression readings that showed good compression for the other cylinders that weren't damaged, then I would believe there is no need to replace other valves. I'm a believer in the maxim "if it ain't broke don't fix it".
Thanks for the rating and nomination. Let me know if you are lacking any details on re-installing the parts you have removed/replaced so far.
