CAM SHAFT TOWER SEAL LEAKING ** PLEASE READ***

Stories like this are whey I keep putting off having mine fixed. Drips on drivers side and has been for some time. Have 24K of Platinum left to think about it.

Took the Tree to Toyota, I get they have to verify themselves but (A) who makes up a spark plug tube full of oil & (B) who opens a valve cover to damage the gasket?

They determined it needs to be replaced & gave me a '24 Highlander loaner. (last year it was a '23 Tacoma)

 

2010 Tundra 5.7 117000 miles,just wanted to post pics to confirm my suspicions.
Wasn’t leaking when I bought it 11000 miles ago,passenger side only.

 

It probably was leaking but cleaned off before you bought it.

 

Is it possible that a bad pcv valve could cause this leak? I decided to check mine, and it was bad! I’m 62 and I’ve never found a bad PCV valve before, but then again I’ve probably only checked 5 or 6 through the years.
Has anyone ever tried any kind of oil leak fixer in a can to try and stop these leaks?
I’m thinking about trying Auto -rx on mine,truck has 118,000 miles on it.
I replaced the PCV valve and cleaned up the oil, I’ll keep an eye on it and see how it goes. Here are before, and after pics.When I say front,that means toward the front of the engine

 

How toasted am I? 220k

 

That's been leaking for many many Moons it seems, check the oil, and drive it until its intended death in the far away future.

 

Is this something that’s going to leak more over time or “if it’s made it that far, it’s fine.” And if sometime I do get it repaired, does opening the engine on a 200k+ truck open up more even more possible issues?

Seen 43 states in her!

 

Too old to open it up. Let it leak.

 

It is fine, completely healthy

Considering it has seen 43 states
Tighten some bolts and continue
