I noticed this before but never really took much concern to it until I went to the track. It seems as though I have a small leak around one of my heads. I'm not sure what the part on top of the head is but it seems to have leaked or is leaking but very slowly. Could one of you that know more mechanics than I do look over the pictures and see what might be happening post your opinions.

No one would really even know there was a leak unless they pulled off the stock Intake.

Also, would there be a power loss at all due to this?

Very High resolution pictures are in my gallery

Thanks

 

It's the TSB oil leak from the small cover mounted on the valve cover. Mine didn't look as bad as yours, but I cleaned it up and need to take it in. Your right if you never take your cover off you'll never see it. It's more obvious on the other side by the oil filler. The small rubber gaskets don't do a very good job.

 

Gator - mine did the same thing on both sides, those are just the breather assemblies on the valve cover.

When I pulled my valve covers off - the breather assemblies are just sealed with black silicone gasket sealant - not gaskets.

I purchased a tube for $20 from MB part #A 003 989 98 20 10 - seemed like a fair deal for tube that can be used in a caulking gun.

Just remove the bolts - 4 on the side you show - six on the "oil filler" side, and remove from the valve covers. Clean off the old silicone using a scotch brite or steel wool pad in the little recess' and around the bolt holes (you won't miss it cuz ya gotta clean the old crap out) and apply a liberal amount of silicone in each "cup" - more is better, re-assemble and torque to 7 lbs. You should see silicone squeeze out form the edges. Trim the excess silcone when cured.

Don't worry about the valve cover gaskets - there made of rubber and are re-usable.

 

Gator, I had same problem with both SRT's. The dealer replaced valve cover gaskets on both under warenty.

 

i found the same thing when i installed my NeedsWings CAI. i bought some Torx sockets and found that most of the bolts on the passenger side were a little loose. maybe that wasn't the problem.

thanks for the heads up on the TSB.

 

Upon reading the title of this thread, I though perhaps we had witnessed our first head–to-block gasket failure. IIRC, even guys running substantial increases in boost and/or nitrous have yet blow those gaskets. Affalterbach built them hell bent for strong. The niggling issues we’ve often experienced are another matter entirely. Fortunately, they’re most often easily and inexpensively rectified.

The PCV system leak is an easy DIY fix if you’re out of warranty. TruTaing shared a fine pictorial…https://www.crossfireforum.org/forum...ad.php?t=24075

BrianBrave- your polished cam covers look sharp!
