Bypass Filter Question
Bypass Filter Question
(OP)
I have installed a bypass filter (Amsoil BMK-13) and I noticed that the oil pressure now takes 3 to 4 seconds to build up during start-ups. I am assuming it is because the hoses drain back when the engine is off. The filter mount, which contains both the full flow and bypass, is located higher than where the original oil filter location used to be. The filter adaptor plate does not have an anti-drainback valve and it seems to me that it needs one. How big of a problem is this?

Be that as it may...using a 'hot shutdown' and then a 'cold restart' senario, then I could definately see the possibility of increased bearing wear and/or damage if the engine is running for several seconds before the oil press comes up enough to 'float' the crank. In my wetsump race engines that have remote filters and coolers with all the attendant AN-10 lines, I use an "Accusump" to 'float the crank' before I do any cold startup. I never start one of these engines without first establishing a good pressure reading on the guage. "Accusump" can be ordered from any of the racing shops. www.pegasusautoracing.com is where mine come from. All up in the neighborhood of $200 to $300.
