Considering gx460, cam tower leak (1 Viewer)

[steelynorm]

I currently have a 100 series, that 4.7 is crazy reliable!
I have been reading researching a lot on the new toyota
v8s some of them have been having cam tower leaks on the 5.7.
is this issue showing up on the 4.6s?
it is not a cheap or easy fix!.
Would really like to get into a 460 but am concerned that the 4.6 v8 is not going to be as trouble free as 4.7.

My wife and I both had 100 series LC's, her's at 285k miles when we traded it in for a Taco for her and my had 255, when I traded it in for my GX460. Never had an issue with my wife's LC, and aside from it starting to look tired, I'd take that cross country in a heartbeat, the same with mine! Although my LC did have a rear seal leak. Very minor and never need to add oil. Just a little low when I took it in for regular oil changes.

Now my GX only has 45k miles. So far it runs outstanding!!! We love it!!

How many miles are you seeing (or reading) that at?

Talked to my mechanic and he told me about the problem, started googling.
My mechanic said same thing I read on a tundra forum
When toyota was sealing up.engines using FIPG the surfaces were too smooth and it has been causing oil.leaks.

I was not sure if 4.6 was having an issue ?

have never heard of this on the GX platform...
heard of it a handful of times on the earlier model LC200's 2008-2012...

There are issues with the front timing cover and the valve covers leaking on the 4.6. Another issue, but this so far seems very rare is a coolant valley plate leak.

Purchasing 2013 GX460 - Items to look out for?

I have found a fair deal on a 2013 LX460 Premium (has everything buy Crawl) with impeccable dealer service records and 50k miles on the clock. Aside from any obvious rust on the underside (shouldn't have much being a TX vehicle) and testing the locking center diff, are there any other obvious...
