#4807925 - 07/07/18 08:16 PM Under Valve Cover Pics - 07 Pacifica 4.0L V6

This is a '07 Chrysler Pacifica with 4.0L SOHC V6 and 6 speed auto. It's a close relative of the SOHC 3.5L V6 which is far more popular. Had the engine bay halfway apart to do a timing belt service @ 129k. Did the plugs, valve cover gaskets, basically everything else within easy reach while I was at it. Unknown maintenance history (car is new to me), there are a couple scribbles in the maintenance manual about two recent oil changes @ 111k and 123k IIRC. Both were Valvoline Synthetic 10w-30.

The car had three owners before me, first was a 2-year lease, the 2nd from 24k - 75k, the last from 75-129k. I contacted the most recent owner on Facebook, it sounded like he didn't do much maintenance on the car-- timing belt service (and about everything else) was skipped which is why I'm doing it now.

Front bank:





Rear bank:

I am going to guess that the rear bank runs hotter than the front or does the engine use some sort of cylinder deactivation to improve fuel economy?

My thoughts as well, rear bank runs hotter. Both looks great, but the front looks fantastic!

Rear bank is stuffed back by the firewall, front bank is more open and has air movement around it the majority of the time. I've seen this before on transverse V6 engines-- the rear bank of my Honda J35 V6 is noticeably darker than the front, though perhaps not to this degree...

No cylinder deactivation on this engine, nor variable valve timing. It does have staged intake runners, but other than that it's a plain Jane port injected transverse v6.

Not bad looking good, a tad varnished from extra heat behind the engine. It'll go another 100,000+

I agree. Looks like another 130k or more is very possible.

Front looks brand new, rear not bad at all.

Those rocker arms would live with 1500+# of open pressure, no clue why those are so massive. I'm no ChryCo fan, but that engine looks pretty clean. Credit to Valvoline! smile

Usually the clean valve cover is where clean air enters the engine and the varnished valve cover has the PCV. Check for varnish sludge in PCV hose and buildup in intake and on intake valves. Probable only slight accumulation.

Looks good, nothing to worry about there. Perfectly normal for the rear head of a transverse engine to look cleaner than the front. Continue what you're doing.
