RE: Re: Pre-oiler Pump?
Here is a thread that shows the system I built.

Because I live in a cold climate I chose to go with the pre-lube pump and high efficiency inverted top of block mounted filters that would drain down into the block.
I couldn't see going with remote filters that do not take advantage of engine heat to get the oil flowing trough them or top of motor mounted check valve filters (like Jatonka's) that have to be warmed up before the cold oil is warmed by engine heat to purge the filters and stop the bypassing. Logic says it's one thing to have instant oil pressure and another to have instant filtration. IMHO, having to clear a plug of below zero oil from a couple of filters on a 30-below morning isn't the fastest way to efficient filtration
I went with non-check valve (drain-down) #1970 five micron filters. If memory serves me properly the 1970s almost double the capacity requirement of the oil pump and the stock filters. I believe the Jatonka filters are somewhere around 16 to 20 micron.
To go for the ultimate in filtration I also chose to go with a remote Amsoil bypass filter. Unlike the main filters, it doesn''t worry me when the Amsoil filter bypasses for 30 minutes on a cold morning.
I take mechanical oil pressure readings between the oil pump and the 1970 filters, immediately after the 1970 filters and at the end of the oil gallery/at the turbo so I've got a pretty good idea of what's going on and when.
I use two oil pan heaters and two freeze plug coolant heaters. When I elect to build a fire in Rosie on a 30-below zero January morning the filters are clear of cold oil and the oil in the pan is warm. After running the pre-lube pump for approx 30 seconds and a shot of tequila sunrise (ether) Rosie has instant oil pressure AND instant filtration followed by instant activity on the fire deck.
If I lived in a warm climate I would probably elect to go with Jatonka's system AND and Amsoil bypass filter to make up for the 16 to 20 micron filter spec.
I hope this sheds some light on the overall logic as to go or not to go with a pre-lube system. Jatonka has a good system but IMHO his system isn't the optimum for all seasons.
In closing I'd like to say that building and installing a pre-lube system in a PITA.
I Hope this helps.
