Did it have anything to do with the oil filter and mount? I really don't need any additional oil cooling, but I was thinking of adding a small exchanger due to another new gizmo I installed. As I am using an EWP for coolant, I've experienced an issue that won't effect most of you down in the banana belt. During long descents in the winter, the automatic controller slows the coolant flow down in an effort to maintain engine temp, this low flow results in not enough flow through my heater core and it gets damn cold in a real hurry. This wouldn't be a big deal, except that normally it's toasty warm in the cabin in all weather, so I don't need to dress in a heavy jacket. I can override the automatic controller or even switch on the backup EWP to maintain coolant flow, but then the engine will cool off completely and eventually it will still begin to blow cold air through the heater core. To resolve this issue I bought an EBP (electric booster pump) from Leon (Davies Craig). This is a very cute little pump that fits very nicely in my heater line and allows me to maintain heat while the EWP is at it's minimum flow setting. It also adds a little extra coolant circulation through the block with out excessively cooling the engine. This brings me to my new opportunity... I keep thinking about the possibility of a small heat exchanger in this location as plumbing would be simple since I have the oil lines coming from the cooler and remote filter in close proximity. This would allow a small amount of heat transfer as a sort of heat balance. I've noticed that oil takes longer to heat up than the coolant, but cools off much slower as well due to it's lower thermal conductivity. This really isn't a problem, but an exchanger would balance this. This pump would also allow a small amount of coolant heat rejection in the incredibly unlikely event of both EWP's failing. Really I'm just considering adding extra weight to address a problem that I don't even have just to take advantage of an opportunity. But that's what tinkerer's do I guess.... (like I don't have enough to do already?)
