So after a pretty major service and almost a thousand miles later... few things I noticed.

- Bosch Plat 4's are CRAP, my slight misfire disappeared after switching to NGK IX's.
- The Bilstein B4's are too soft... anyone know if Bilstein makes a B6 shock for our front shocks? I had the shocks installed per Heindrich thread and the rears are B6's, with the fronts being B4's.
- And for everyone who uses Royal Purple, I'll let the picture do the talking. Not only did I replace gaskets... I also replaced the valve cover from warpage. My first time hearing a M113 valve cover being warped. My engine has 97k miles on it, with 7-8k mile oil changes.

Are those rockers supposed to look good, after the royal purple??

Nocturnal-G

According to everyone who swears by Royal Purple, unless I'm missing something? lol.

Shifter

They usually turn a goldish brown color, So i'm not sure what you are implying what the purple did or is good?

Nocturnal-G

I'm told they are supposed to look like this:

I'm pretty sure the pic you post on the CLEEEAAAANNN internall engine not has more than 50kmilles and maybe ussing Motul :S i only see aluminium colored engines with motul motoroil. but this engine looks like new! (maybe this pic are taken when change the rocker/lifter mount by the common ticking noise)

My engine looks exelent clean ussing mobil 1 every 8k but the rockers/valvetrain looks bright yellowish colored

You know who is the owner of the pic to ask about?

Just replaced valve covers at 86K

Mobil 1 0w40 only, @ 4-6K intervals.

This looks correct - if I was the OP I would consider emailing Royal Purple this photo and ask them if this is normal ?

Nocturnal-G

I highly doubt this is normal... I am definitely going to switch over to Mobil 1 after this.

That's how mine looked at 100k+ when we swapped valve cover gaskets.

When i did my valve cover gaskets at 125k it was nice and clean inside. I've used royal purple before. Between 5 friends and I that all have tried royal purple, all of us has experienced some sort of oil burning. I will never touch another royal purple product again.

Nocturnal-G

What do you currently use? And what are the consequences of continued use of RP, if anyone knows?

desired_speeds

I'm currently using Motul x-cess 8100 5w-40 this past oil change. The previous two times I used Amsoil European formula 5w-40. I change my oil every 7000-7500 miles.

I never liked RP because it always gave me a weird feeling. The engine on my previous car felt slightly rougher when I used RP, not to mention burned some in the 3000mi. oil change interval. I just have a hunch that it doesn't lubricate as well as other oils.

Nocturnal-G

I'll probably use something that's MB recommended next time... if not, I'll just use Mobil 1.

Nocturnal-G

What kind of oil do you use?
