Valve Cover Change 2006 Sentra Spec V (pics)

[Xeno]

Changed the valve cover on my 06 Sentra with QR25DE. Current oil is Mobil 1 Extended Performance 5w30.

54k miles on the engine.

Ran the following oil during its life:
-70% Mobil 1 5w30
-20% Mobil 1 Extended Performance 5w30
-Pennzoil Ultra 1 OCI
-Royal Purple 1 OCI
-Havoline Conventional 5w30

This car sees lots of track and mountain roads (high rpm), so I changed about every 5k.

Boring, thanks for sharing.

I would keep using same oil and OCI.

 

[gregk24]

Wow, keep doing what your doing!

 

[OVERKILL]

Looks fantastic

Good job taking care of this motor! I worked at a Havoline Xpress lube shop before, and I've seen a lot of cars with between 50,000 to 80,000 miles that seem to be well taken care of, build up a heavy amount of varnish on the internals.

That valve train looks like the day it was made in the factory!

Very nice!

Why did you take the valve cove off? Morbid curiosity?

 

[JAG]

It's so clean because Mobil 1 5w30 stripped off a layer or iron and steel, hence the high wear metals often seen in used oil analysis. Just kidding!

Thanks guys. I try to give her good maintenance, had the car since I was 18, now 25.

One of the spark plug seals had a slight leak.

no pics of under the valve cover?

 

[LazyPrizm]

Worrrr... that's hard to believe. Nice!

 

[Merkava_4]

So which oil did all the cleaning, Royal Purple or PU ?

 

[285south]

Mobil 1 a course cleaned that up. Looking forward to mine in 20 months...when I take off my valve cover and see the varnish completely gone. But mine would be a mix of synthetics, oldest stuff I have used first as well; M1 and Castrol SynTec not Edge.

Yes, nice indeed! I have the same engine in my '04 Altima 2.5S. I should think that mine looks similar

Did you replace the PCV while you were in there? Probably no need really since everything is sooooo clean!

 

[Hyde244]

This is still a young engine. Curious as to why you took the valve cover off?

Also at such low mileage, I wouldn't expect any engine to really be that dirty at a normal OCI. What would be more interesting is taking the cover off after 100K or 150K of quality synthetic use to see how the engine holds up.

Great lookin'....though I think that with only 54k miles any engine with 5 OCs should be as clean...key word being should...
