Yes.
The HP filters fail too.
Samething engine starts to lose oil pressure for no apparent reason, friend of mine ran them exclusively on his BBC, after having this happen with several NEW HP filters he switched to a purolator filter and the problem went away.
Spread the word.
Tell everybody you know how crappy their filters are and too STOP using them, when the word gets out to enough people they will have no choice but to improve their product.
