    Default Dan Olson Oil Cooler Pros and Cons?

    Can anyone comment on experience with Dan Olson BBC block mounted oil cooler? I have one I was planning on using for a new build. I see a large number of them for sale, so I'm wondering if there is any issues with them other than making sure there real clean? Leak prone?

    They work fine. I ran one on the turbo engine in my Schiada. Go ahead and get the o-ring kit for it and open it up. Mark the orientation of the end cap so the fitting will face the correct direction when you re-assemble it. Then you can inspect the core to make sure it's clean, as well as checking both end caps to make sure there is not too much corrosion that would cause the large o-rings not to seal, or even get thin enough that the caps could leak water through the aluminum.

    OK, Thanks for the response Barry. Cooler seems like a nice piece of hardware. I just been kinda bit leery seeing how many I see for sale.

    I know mine takes about 40* of heat out of my oil. Mine is also force fed water.

    Another tidbit to consider if it is block mounted is ....space ...do you have enough room for one ?
    they are not exactly small coolers

    Right, I removed the Olson cooler on my 21' Howard because the oil hardly got hot enough, unless I ran it flat out a couple of times in succession.

    General consensus (at least in my field) for "normal" dinosaur oil is 250*F in the sump as a good high end limit.....I like to target operating temp around 210*F so it boils the moisture out of the oil.

    I run a remote Dan Olson with my ford flatty. I run the hot water out of the engine and put it through the inlet on the oil cooler, thus oil temp comes up easier!
