Filters, bypass, and break-in

[NovaMan]

I have to believe this has been covered before, but apparently I suck at searching. This isn't really for a race engine, but it could be; it's a 350 Chevy for my truck. I'd like all the oil to go through the filter (the engine isn't perfectly clean, but I've been told I'm being too picky), but I'd rather have dirty oil than a filter blowing off the engine or something horrible like that. Should I plug the oil filter bypass? I was planning on using a Purolator L34631, which has its own internal bypass that I'm hoping is a little stiffer than GM's 4psi relief.

I've decided I must plug the GM bypass, but I found out that the L34631 filter doesn't have an internal bypass. What filter should I use for break-in?

I'd look at a remote setup. Then run larger FL1A type filters.....and get more capacity at the same time. I run a dual remote setup on two of my cars.

It looks like that may be the only way to run a filter with an internal bypass.

AHA! Looks like Baldwin's B279 has 13/16"-16 threads and a 20psi relief valve. (Hastings' LF349 is identical.) Has anyone ever cut one of these manufacturers' filters open? Do they seem to have sufficient filter media area?

Check with Fram. I believe their HP4 includes a ~20psi bypass also.

Are Fram's HP-series oil filters better quality than their regular oil filters?
