is anybody else having these oil seepage problems? i'm not, well other than my feed fitting

are you sure there isn't something askew with your setup Carlos? that seems like a lot of oil.

i don't totally understand what you're doing with the filter. does the crankcase breather normally vent into the throttle bodies? if so, how you would get oil seepage back into the IC and other plumbing?

i'd be surprised if this was a common issue and EVO hasn't addresses it yet.

 

i thought there was something wrong but, after doing a lot of internet research, this seems to be a normal occurrence. it may have been exacerbated by my over filling of the oil reservoir .

under normal circumstances the NA crankcase breather attaches to the throttle body. you don't notice any oil build up because it doesn't have a chance to accumulate. the SC kit routes the breather to the intake plumbing (between the filter and the SC) where there is a greater chance for the oil to pool. this oil then gets sucked by the SC and onto the IC. i attached the filter to the breather hose and did not bother to route it back to the intake (disclaimer: this is for racing purposes only). as you can see in the pics of the catch can, there's quite a bit of oil accumulation. all this stuff would normally go through your throttle body. if i still get oil in the boost hoses/IC even with the filtering and not routing back to the intake then i know the SC unit is bad.

EVO has to route it back to the intake pipes to be in emissions compliance.

again, this is a normal occurrence especially with boosted cars.

one more thing... the seepage was with the old boost hoses. with the new silicone ones i am able to really clamp down on them so now there is no oil seeping past the connections. all the oil is trapped in there

 

You sure are blowing alot of oil. I have had this setup for more than 2 years and haven't had to drain the can yet. Are you running the Mobil Water (0W40)?

 

dude you are scaring me

i'll run the catch can and if there is still oil in the boost pipes/IC then the SC was contributing to the accumulation.

still running the 0w40. that guy on rennlist (and the pca tech article) convinced me that it is fine if not better for the valve train.

 

Curious what size lines are you running into your catch can.

 

Whatever the stock line is. I think it is 3/4" ID.

 

The "guy" who wrote that article seems to change his mind depending on what Porsche is currently saying. He normally repeats factory recommendations. Check this article out. I wonder why he was running 15W50 in HIS car and explains why? He also recommends 0W40 ONLY in cool weather. When was he wrong? Now or then? In another article he claims that the valve tappet noise is due to the oil being too thin (which is correct), yet now he is recommending thinner oil?

You know my optinion on Moble Water. I wouldn't run that in any climate above freezing in any car. That is, unless I wasn't planning on keeping the car for more than a few years and didn't mind oil consumption and leakage.

 

I am very tempted to pull the trigger on my 02 c2.

what is the estimated whp on this kit and quarter mile times?

 

super happy with my EVO SC had rpmracinginc.com do it when it first came out i think mine is number 23. its been working well, a few kinks in the first week and nothing since.

 

here's the corrected link LINK you were missing a "}"

funny, i have been using 0w40 all this time. 86K miles and no leakage/RMS. i know nothing about oil so i need guidance from others so this is really confusing. i think i'll just go with castrol 0w50 to cover all opinions

regarding oil consumption, my car doesn't burn that much oil


can you show us pics of your catch can?

edit: the article you posted was 2002. the most recent article and the one i posted was from 2005, has him saying it is OK but still recommends 0w-40

he actually says 15w-50 will be louder upon start up until the oil becomes warm enough and thin enough to fill the tappets.

was he wrong then or now? he was just revising his opinion.

 

You can add me to the list.. Happy with my EVO SC.

He is absolutley wrong in his arguement. Here states "We are thinking that Porsche favors the 40 top weight over the 50 for street use because it is friendlier to the hydraulic valve adjusters (993 and 986/996) and other areas of the VarioCam valve train (986/996). In the case of the former, we have seen some of these newer cars struggle to achieve compression on startup in certain circumstances because the hydraulic valve adjusters are not pressurizing correctly" which is a crock of ****. The higher (heated) viscosity weight of the oil has absolutley nothing to do with loss of hydarulics in the lifters. It is the LOWER (COOL) viscosity that controls this at start up.

The point I am making is that this guy does not seem to have any solid beliefs and changes "opinion" depending on how the wind blows. You should read his answers to many other queations. They are all over the place. I certainly would take his "opiinion's" as just that, as they certainly don't reflect any actual experience on his part. Many of his answers seem to rely on him asking some oither guy to give his opinion.

You might be surprised if you measure the oil temp in your car after some hot runs. They can get as high as the oil in the air cooled engines. If you're blowing that much oil out the crankcase, it very well could be a sign that the 0W40 is NOT doing the job it claims it will do...and that's protecting your engine from wear.

 

do any of you guys have a pic of the EVO setup where the crankcase breather vents into the intake plumbing? i'd like to see what your talking about. i would go look at mine, but it's still in the shop

 

geeess.... i didn't realize what i started with this thread. over 10K views and almost 400 posts. not too shabby. i'm surprised with this much exposure we can't get Evo to chime in here from time to time with their opinions/suggestions like they do in the turbo section. it would be nice to hear their thoughts on some of these topics.

by the way, my dealer is now recommending 0W-40 again. they kind of flip flop from time to time depending on what porsche is saying. they were suggesting another brand (besides Mobil 1) a few months ago (i think it was castrol syntec) with a 5W-40 viscotisity. now they're back to Mobil 1 0W-40 again.
