Thank you for the kind words. Remember that good judgment comes from experience; experience comes from bad judgment. We learned along the way. Fortunately for me, I had some great teachers.

That's an interesting observation. Oil viscosity ratings are supposed to be standardized. On the face of it, that should not be true. However, there are probably other factors at work that I am not considering. Anyone know for certain what might cause RP oil do this?

The 5W-20 designation means that it has the viscosity of 5-weight oil when cold, but will not dilute to a lower viscosity than 20-weight when at temperature. The long chain polymers are supposed to uncurl and make it more viscous as it heats up.

One point to remember: If your engine overheats significantly, change your oil also. The oil will revert to the lowest number if it breaks down. In our case, it's 5-weight.

Been very happy with Castrol Syntec 5W-20 full synthetic so far. Costs $21 for a 5-quart jug at WalMart (only reason I go there besides the fact that they carry the Nestea instant iced tea I prefer). Buy a better oil filter elsewhere. Bit of a PITA, but it gives me peace of mind.

Thumbs up Re: Is this the PCV valve?

Man I just changed mine yesterday I cleaned the old one it looked like the one in the picture you got. I got mine at napa it was blue but fit fine. I had 33k miles on the old one. The bad problem I got is the intake is covered with alot of sprayed oil. I want to clean it all out but how to get it all out. I cleaned the tb plates front and back .

An oil catch can will stop more stuff from getting in there. Haven't heard a good way (except SeaFoam-type cleaners) to get it out.

If I were determined to get it clean, I would remove the intake manifold from engine and either dunk it or spray the insides in a Safe-T-Clean tank to dissolve the crud.

Looks to me from the attached pictures (credit to http://www.wkjeeps.com/engine/hemi_57_engine10.jpg ) and the parts book that this is a 2-piece component.




I think your '05 has the octopus of ignition wires on top also, like this: .

Means all of that has to come off. I think I remember reading that the fuel rails come off too. I was going to do mine also, but this made me think twice.

If you are going to do it, there is an intake manifold gasket kit you'll want to get beforehand. We'd be interested in hearing how it turns out and if there is any significant performance improvement. You could be starting a whole new HEMI trend..... It would be great thread.

Re: Is this the PCV valve?

Wow that looks like a lot of work, Is it possible to take off the TB and reach in the intake with a rag with a cleaner and wipe it out or I may go with doing the seaform spray thing that I saw on there web site. There is also some mopar intake cleaner I saw on the LX site guys are using to clean it out.

Re: Is this the PCV valve?

Walt, that's what the stock 05's look like, and that WKjeeps pix of the octapus is real good except they're missing 4 coils and 8 spark plugs, LOL!!

ChrisWk, you can clean it without removing, but it's not the best way (remove like Walt said is best), but you won't get it completely clean and run the risk of some of that crud getting down into the runners, the combustion chambers and even perhaps plug/restrict an injector. If you do it that way, be extremely careful.

SHould be the same rating, but RP is defintiely thicker compared to Valvoline, which I noticed right away when pouring it into the crankcase at room temp. Never going with RP again; the MDS is now much smoother, compared to the rough transitions when running with RP.

Thanks. That's good info to remember. I'll stay with Castrol Syntec or Mobil-1 5W-20.

It's available at dealer and aftermarket and also runs ~$25. I changed all that stuff at my 60K inspection/maintenance. Will be doing the 02 Sensors on Saturday, as they're becoming lazy.
Where is the Map sensor location do you have a picture of it?

ChrisWK
Rear end of intake manifold (on vertical "bubble" part). 1/4 turn plug-in; 1 electrical connector.

PITA to access. MAP sensor part no. 5033310-AC; ~$25 at dealer. Probably cheaper at parts store.
