Good read on what the wrong type of filter will do and how quickly you can lose months of build time and thousands and thousands of dollars.

So Bob, I would just be careful doing this and ensure that the proper style filter is used. However, even if the filter is capable, are the tiny lines feeding the coolant bypass filter large enough to support that kind of flow? Me thinks not... :humm:

If you have ever pulled that pisser tube off the intake you will see it doesnt pass alot of coolant anyways, plus there is a second path for the coolant to flow back to the water pump through the manifold. I am not talking about the main water line, I am talking about the 1/4 or 5/16 line that comes off the top af radiator and goes directly to the degass bottle, that is the line they are using for the bypass is it not??

On a bit of a separate subject, what type of sealant should I use on the threaded connections on the bypass head? It came with teflon tape, but I've ready it's better to use a paste type sealant. Anything in particular you would recommend?

I always use the tape, just make sure you don't go past the threads on the leading side so pieces don't get into the cooling system, teflon paste is good but takes a long while to set up.

Then it's still just a by-pass filter.

I used the teflon tape, no issues here.

I will use the teflon tape too then. Thanks for the info.

I really want to get a good flush after I've run the filter for a while. I don't want to be one of the folks that gets a new oil cooler put on only to not have delta's improve and clog up the new cooler too.
