I just put crower(not bc's) 272's in my 2.0 and used the oem clearances.
I haven't found any failure issues with a 2.0 but it seems the ej20 needs to be idle around 1200 rpm to idle decent, could the extra oil pressure be saving the cams in those engines? |

They probably switched foundries, or have a new cam manufacturer for the blanks.
Hopefully they have markings that can be identified by whatever changed. In aircraft engines continental and lycoming will give compenents new part numbers when they switch something up, and subsequntly the faa will determine cause of failure and issue an airworthieness directed to rip the engine apart and determine what part number or serial number was installed if people are having problems with a new batch. Everyone in the aviation community bitches when an AD comes out because they have to dump money to pay someone to inspect what they have and correct a problem that hasn't surfaced necessarily in their engine yet... Its funny for me to see all of you struggling and ranting about what changed. I have had two sti's with gsc s2 cams and have never had a problem, I suspect they changed where they are getting their blanks from, or are outsourcing to a different company. |

Glad to hear people are researching. Just put in GSC S1 cams and beehive springs in my latest build. 3k miles so far and seems good. No noises that I'm aware of, idle is great and making power.
Brad Penn break-in oil. Ran at 2k rpms for 20 mins, then changed oil. Another change at 300 miles, then switched to Rotella T6 at ~950 miles. Was planning on sending in a sample of oil for analysis soon. Did lots of engine breaking, starting turning up power around 600 miles. Hoping I'm not playing russian roulette here |

The current data shows most failures occurring by no more than 1500 miles. All the guys with 2500+ miles can most likely stop worrying.

Wow this sucks, I have a set of GSC s2 cams that im going to be putting in my built motor and am now having second thoughts. Is there some type of marking/stamp of which type of gsc cams are coming apart? Does anybody know if GSC and Kelford are coming forward with this problem and resolving this issue any time soon?

its very common in v8 engine to have to raise the idle to keep the valve train lubricated.
