Multiple Oil filter Blow Outs

[elev8_dude]

Well I switched to a new filter with relief (K&N HP-3001) and switched oil to 20w-50.

As for the 30w I meant 40w and my mechanic has suggested I run that oil here in Florida.

My engine was recently rebuilt, so as for the internals, there is alot of new parts , rings/gaskets, etc.

The blow out happen on our first real cold snap. And from what I've read and asked 40w is not the best (to say the least) as 25-35 degree, morning start oil.

Thanks for all your help. Any help is always appreciated.
