Not surprising.. If they attended my classes, they would know about it. Unless someone dissects the unit they will never understand this. Most shops have done nothing more to these engines than re-seal cam covers.

When this seal fails ultimately camshaft deviations will occur as the adjuster will no longer function. Its not catastrophic, but when it goes long enough it will set a CEL and account for crappy gas mileage.
