Did you check the line at the valve cover connection breather hose ??

Below dead center with green line.






Do you have headers ?? Was the OEM dipstick recently removed creating an issue at the O-Ring??

You have a blower, if crankcase pressure is high, excessive oil may be coming from the dip stick tube or the valve cover breather filter in the rear.

Yes I do have sikky headers the first model they had with the relocation of the oil dip stick haven’t touch anything around there except for plugs and oil change recently that rrracing perform. Rafi was very helpful with taking my car in this time also I doubt they touched it because happened 750 miles after I left the shop and that’s what I have on my trip mileage. Other then that car runs like its brand new . And no it’s not coming out of the breather hose. Gonna get a update tomorrow and hope it’s nothing major just a seal probably somewhere and thanks everyone for trying to help out appreciate it and hope everyone is safe

Hey JoeZ about the green line and the breather hose . I remembered adjusting this too I push the hose down and clamped it and I don’t think it’s at the middle more like snugged and fully on

Posted on your other post but dam seems like it’s starting to be a trend. Prior to you installing the SC your compression numbers were great. Sucks to hear another one fall victim to this ringland issue. Pistons I would go with JE and posted the link to BC rods on your other post. Keep us posted and good luck on your build.

The ring stack is too tightly packed on the piston, so the ring lands are fragile from the factory. This helps with making power, but sucks for service life. Our rings are also pretty thin which means they stress the pistons more by flexing against the ring lands more than a thicker ring would.

There's nothing "wrong" with this design for the factory power level. It's definitely not the best under boost.

Looks like a street kit so you aren't running full E85.

What blend E85 are you running? How are you monitoring that?

I've always been on the fence about those mid-range, blended fuel tunes. Lots of room for error.

So what percent did the gauge read? Are you mixing it with 93 octane?

What was told to me and recommend from Simon and Rafi was 40-60 with 93 and when I did use the e85 I would use it all up didn’t let it sit long plus I never let my gas gauge also go under half a tank . Gauge would read 40 after little driving would burn off and decrease eventually

What do you mean it would decrease eventually? You mean the gauge would read lower than 40% at times?

yes when your driving and using it up . It will eventually get lower like your regular gas gauge when u drive but to 9 percent or 10 percent becuase regular gas has 10 percent ethanol already so that’s the lowest it will get and read to
