Better change your oil on time from now on. After one overhaul, you'd
think you'd figured it out by now.

bigger oil drain channels from the heads back to the pan

the oil was cooking and coking in the heads

The short of this story, reguardless of the BS that some were
expressing on this list in Apl 02 when the first rebuild, is that th
engine was rebuilt at 46,500 sludged up and pinging under load. First
oil changes were done at 7,500 mile each with Mobil 1. Figured our
newest car was worth the effort. My 88 Camry just turned 251,000 and
my 93 pickup 201,000 last week. Been a faithful Toyota guy for years,
couldn't complain!

Dealer bad mouthed me and the wife , calling us liars, nice dealership
huh?

Next thing car was done and engine all set....

Wife says that the oil change intervals were bogus at 7500 miles and
she wanted to do what the repair manager said and change it every
3000.

Droped the son off last week and realized that the knocking is coming
back and used the same "carbon build-up" test the dealer manager
showed me , foot on the brake and torque up the motor to load it...
shure enough its knocking again.

Expect it to be covered but this is rediculious. So here we go again,
didn't expect tohave to go thugh this again after the dealer service
manager says last time it was our fault and that its a "good business
decision" of Toyota and that if he had the chance he wouldn't cover it
last time.

Have to decide now what the story will be. My step sister in Michigan
had her Lexus motor in her SUV changed with the same issue last fall.
Hard to understand the sediment of others on this NG that say its just
bad maintanence.

Just wondering...

Did you have the oil changed at the dealer either time?

No, it was the dirt in the oil that was cooking, but I thought it was
from being too cold? The holes where the oil runs out of the head is the
is a rectangle hole about 1.5" by about 2", so I dont think that was it
either. Its from not changing his oil. He'd better have servcie slips,
and all of these repairs MUST be OK'd by the DSM, its not a "done deal"
as Mike would lead you to beleive.

Well, your original post said it was the same symptoms, but if you've
done it at 3000 miles, I'll put money its not sludge. Maybe you just
have ping from low octane or carbon deposits?

Is there any other way to clean carbon deposits other than a break down and clean ?
