Engine Please Help

Well we called one toyota dealer and they gave us a run around, the other one agreed to fix it, pay for the tow and rental car but they have to see the car to make sure it is sludge. this is exactly what i want but a little leary about whether there for real. they didn't ask for receipts or maybe they will later on but at least they wanted to help. They wanted us to do a comment sheet on other dealer. We're going to have our personal mechanic look at the diifferent areas where sludge might be and get written statement just in case. i saw the pictures posted about sludge. We saw sludge where you put the oil into, where else would it be conclusively, would you have to remove the valve cover too see. I pray this gesture by toyota dealer is sound
thanks
P.S.
Once this is fixed how do we prevent it from happening again, do we have to change oil more often or use something other than pennzoil or go to dealer for oil change.

I believe the main point of sludge deposition is under the head cover. Yes, you will have to remove the head cover to see it clearly. The head cover itself will be trashed by sludge getting in the breather. There will be alot in the pan also. Go to the sludge zone site:

To prevent it from happening, change the oil every 3k miles for dino oil or 5k miles for synthetics. Be conservative. Use the dealer for your oil changes - verifiable documentation. Personally, if I owned a sludge-prone engine, I would only use synthetic motor oil in it.
