How do I Engine Drivetrain 2nd Gen S Most liked posts in thread: Possible Fix for Carbon Issue on 2nd Gen MINI S and JCW?

^^^Ouch...

Who knows..... Remember these??? Lots were sold to people....

 

The N14 engine has two PCV tracts.... During non boost, there is a direct path under vacuum, directly to the throttle body attached to the intake plenum leading to the intake valves. This is the tract that gets blocked with the caps. The second tract, the PCV oil laden fumes are introduced into the filtered air being drawn into the cold side of the turbo. This is where a OCC can be added to catch the oil laden fumes.... The PCV system still operates... The valve cover is not blocked and no undue pressure is caused (as long as no restrictions are introduced such as undersized OCC hoses and such). So venting is not blocked....

 

Interesting..... opcorn:

 

I will await the opinion from Metalman Chuck.

 

How has that worked for you Don? I saw that & thought it might be a good option, but haven't found any user comments on its success.

 

I actually have pictures somewhere from MITM in August of Scooter puffing smoke during the seafoam treatment.

I do not have pictures of my valves, but power is good. :cornut:

 

I understand that seafoam makes smoke, but how can one tell is it is carbon coming out or just smoke from burning seafoam in the engine? I'm glad your MINI is running better for you Don.

 

Clint this looks like a great idea & a very nice kit. It is encouraging that early reports are promising. Before & after pictures would be incontrovertible.

 

:cornut: Pics For MetalMan Please Such That I can Buy Him A 'Crow Dinner' With All The Trimmings.

I certainly will happily eat crow if the intake valves go from this....



to this....


After a Seafoam treatment or two or even three.....

But I have never seen a before and after picture from a Seafoam treatment....:frown2:

 

:cornut: He's having 2nd thoughts so he's modifying the criteria of the deal. "My God, they're probably correct so I've got to make the deal impossible to accomplish." Sweaty palms and beads of sweat on his forhead as he anxiously sees the truth flash before his(and every one elses)eyes.

Having gone through the Seafoam craze a couple of years ago and reporting my finding I can't say that it definitely helps. Consider the time the seafoam actually has time to soak on the valves in a running engine. Fractions of a second! The fog solution might work better but don't pray the rosary.

I've been using the passenger side PCV delete plugs this year. We'll see how nasty the intercooler is this year when I take it out for a wash.

 

:cornut: No No! When the Seafoam is in, one cuts the engine x30min and then spirited 30min drive. Seafoam has 30min to work on the carbon deposits which are minimal anyway as one's been using it in conjunction with a BSH OCC/BSH dual port by pass valve and repeating Seafoam every 3kmi.

Why didn't spell check catch that? You need to look into this problem Nathan.

You may get a little residual seafoam sitting on top of the piston dome when you finally turn off the ignition, but the rest of it will get burnt off while you're introducing it into the intake while the engine is still running. Any fuel system cleaner can do that job since fuel is being sprayed near the piston dome. If you want to clean the intake ports/valves good you need to do it manually or with a media blaster. The OCC might slow it down a little but 2nd gen MINI owners just need to accept this is a high maintenance engine because of the crappy PCV design. This damn car is a love hate thing for sure!

 

Two errors in your post.....

The BSH Dual Port does not dictate which OCC that can be used....

There is no known OCC that catches all blow by.... Unless you consider your engine is just a large OCC. Which is how the EPA would look at it....

 

:cornut: One may use any OCC that he wants. To me the BSH is the best as it has propper baffling and internal seperation of the two sides to allow propper condensation of the blow by there by keeping it in the OCC. The only known system(in the N14 engine) to catch ALL BLOW BY is the BSH OCC AND the BSH Dual Port valve(or the block off system mentioned in Nathan's post and of course with a propper OCC). Now,the new Block Off system mentioned in Nathan's post blocks the greatest amount of blow by(like a BSH dual port valve used alone) but NOT ALL. To it one must add a propper(baffled and internally seperated)OCC. One may choose another brand of OCC but to me the BSH is the best. The TWO ERRORS that You Made are now explained. For one who does not use any of the three products mentioned, how would you know? Lack of personal knowledge of the subject speaks volumes as to the arguer's credibility.

^^^Ha Ha Ha....
You a funny man......

 

Lots of blow-by in this thread.... opcorn:
