The scored disks look typical of damage due to metal on metal contact. The
two surfaces get so hot they try to fuse together then rip apart, removing a
deeper amount of cast iron from the disk.

"The brakes.... they score .... TOUCH DOWN!" Sorry but, I just could
not resist! LOL
These may be a defect in the new brake pad, such as an imbeded piece of
foreign metal or .... there could be an improper mounting of the caliper
to the anchor. Stuff happens so get the car back to the dealer pronto.

Maybe *you* should go work in a brake shop to learn *what* *is* in the
real world.

OK, I already did one of these munch motors too. It was oversped, oil
pump came apart, probably around 11,000 rpm. Oh, as for the VVTL-i, you
will find the rockers have galled the rocker shaft, twisted it and
sheared the retainer bolt pin and its a blind hole, a bugger to get out.
Oh, platil, dont repair this engine/head, there is a part number that
will get you an entire engine ass'y complete with head. They did this
for these deals only. I found out after I already replaced the short
block and repaired the head with all 16 valves bent!

On Monday, I will try to get more details. Our MDT has been especially
grumpy as of late, so I have kept my usual incessant questions to a minimum.
He got a new short block, but re-used the head after it tested OK. Looks
like he will try to fire it up late Monday. I can tell you the vehicle is
covered with stickers, has a mile high spoiler, and the person is a young
male... I'll let you ponder the probable causes.
As a side note, it's amazing how light the short block is and that I saw no
cylinder cross hatch in the old or new engine? For folks like you and I who
appreciate sound, logical, well executed design and process, the engine
exudes efficient elegance.

MDT Tech (Rick),
Somehow on a new vehicle, I do not see this as normal. It may be normal to
you since you have seen these on a number of Camry SE's as you mentioned.
However the fact remains that a new car should not have this level of
scoring when the front disks look practically new. Either some foreign
matter is rubbing against the rotors when the brake is pressed or there is
some part defect. If that was my car, I would not accept the view of
scoring as normal. I have to say in the past I have agreed to and
appreciated your comments on various issues, but this time I think there is
more to this problem then just normal wear and tear.

I was going by the visual, I have no idea how deep. I have seen all the
brakes score, They add more metal to give you more braking power while
keeping the size small. The SE is a performance/handling version, I dont
know if the brake pads are differnt. I'd take it in and have them look
at it. But from first hand, it happens to lots, its just easier to see
with disc brakes.

Our Toyota MDT said it was a high speed downshift... above 11k RPM's like
Rick said. The oil pump housing from old engine looked like it was
literally blown up...
He got the engine running today.... idle was rough, but ran good at mid and
higher engine speeds. Almost seems as if the "L" (lift) portion of the VVTL
is active at idle, and is causing poor idle performance. Using his Toyota
scan tool, he activated the VVT, and the engine died, so it seems that it is
working.
Maybe the Toyota long block was the way to go... Rick, you have that P/N
handy?
