08 Camry V6, 132K, Valve Covers removed

[The Critic]

FIL’s 08 Camry V6 with 132K.

From 0-55K, it received conventional 5W30 every 5K. From 55K-present, it has used a jobber/store-brand Dexos 1 approved synthetic every 5K. Overall it is clean, but there are some small clumps of sludge in the front cylinder head.

Wow ! ! That certainly looks good.

 

[JoelB]

Interesting how there is basically no varnish anywhere but clumps of sludge exist. Maybe a hot spot in the cylinder head? Or just an area that doesn't get much oil flow?

 

[michaelluscher]

Is this the one with the broken valve spring?

Looks real clean otherwise?

 

[JeffKeryk]

Just another clean Toyletta engine...

 

[Dorian]

Wow. Impressive for 55k of conventional with 5K OCIs!

I noticed that too. ? It looks like some sort of dirty crud.

 

[JC1]

Yes looks very clean. Thanks for the pics. Are you going to try and pick out those pieces of sludge?

Is this just dust or is that lobe damaged? I see some stuff on some of the others too, but this one stands out:

Not sure, I will have to take a closer look.

That looks like some damage when I zoom in to look. Might be wrong

 

[Overfill]

That black stuff could've shaken or fallen to that location when removing the valve cover. It seems out of place given the cleanliness of the engine and lack of varnish.

Agree. The placement and coverage is not random.

I just had someone look at the cam lobes in person - I was told they are fine.

Which one has the broken valve spring?

 

[The Critic]

Which one has the broken valve spring?

Cyl #3 - rear bank, center cylinder.

 

[bullwinkle]

How hard is a valve spring to change on those? Guessing timing chain, cam, follower removal & air hold to keep the valves shut (while pulling the keepers & replacing the spring)? I've only done pushrod ones, guess I'm old...

I like the Rube Goldberg repair on the air intake hoses? Correction: wire loom.

 

[Trav]

What intake hoses? That is the original wiring harness and looks normal.
