Frantz bypass kit
Good morning, I have a 2018 6.7 psd with 110k on the clock and recently installed a frantz oil bypass kit recently I have been hearing the typewriter tick more often than before, is it because of the bypass kit, does this kit hurt the engine more than help, any advice is greatly appreciated

If you are hearing the typewriter tick you either put in 5w40 oil or have 10w30 /15w40 that has sheared down and/or has fuel dilution.
could the frantz export the noise…not impossible…worn or diluted oil heavy with soot would mask the sound and the frantz would remove a lot of the soot.
the type writer tick noise is common and ford says it’s normal .

it has 5w-40 and about 4k on oil, also with two quarts of Lucas in to help with oil starvation on cold starts, I was thinking the same thing with the bypass filtering out all the soot and brand that the oil is so clean that it’s not masking the noise, just wanting to make sure I’m not hurting anything by running the frantz by pass kit
the only factor about by pass kits that is not well understood is:
if you tap the by pass feed at the oil temp sensor port and send the return back to the oil pressure switch port - you are filtering in parallel to the main filter but you dont loose any engine oil pressure
if you tamp at the oil temp switch and send to oil fil cap or engine pan - you are filtering the same oil as the oem filter and you loose a small amount of pressure
if you tap at the oil pressure switch and send the return back to the cap or pan...you are running a two stage...by pass is filtering oil that has already been filtered by oem filter...some oil pressure is lost
a donut at the oil filter that taps the feed may or may not be filtering in parallel and may or may not have a by pass PSI cost penalty.

im a metro driver and that cuases high fuel dilution so I never run my oil past 3k miles if I use 5W40. I dont want oil that is diluted down to a number below 5
10W30 is not as bad...if it dilutes....it will just start crawling towards the 5

what is your opinion on my setup, if the frantz will hurt my engine in the long run I’ll remove it, if not I’ll leave it

from my understanding trucks with weight loss don’t have to worry about dilution, my bypass is taped in via a filter donut and returns via filter cap, the supplied filter adapter nut whole was smaller than the factory so I drilled it bigger to reduce resistance oil supply to the engine, frantz claims the kit doesn’t drop pressure nor flow, but I figured I’d drill it bigger just to be safe
These bypass filters are set up with small ports or lines to restrict flow to the filter to not only keep it slow but to not take away too much oil from the main flow.

the adapter nut that threads onto the oil filter housing, I drilled it bigger than what it was to allow more flow to the engine since from my understanding oil flows from the outside of the main filter to the inside and up that piece
I never changed anything that goes to the bypass filtering itself, I wanted to keep the majority of the flow to the engine

Appears like that adapter is may be your problem.

Something is not right, because if you have a ticking noise that you did not have before, it appears that this adapter is not flowing enough at full flow to the engine. You could always tee off the factory oil pressure switch like I did for my Filtration Solutions FS2500 bypass system.

I still get decent flow coming back into the engine from the bypass kit
