Hello, my name is Pedro and I am a big fan of bypass filters.
I had a Frantz filter fitted to each of my previous vehicles, before selling them I removed the bypass filters and saved them for my new cars.
I spent a lot of time investigating how to install it since from the beginning with the variable oil pump I had many doubts.
To do it right, buy a used filter body and cut it to study the oil flow, after the autopsy I saw that using one of the pressure sensors is not optimal since it is the flow already filtered, so the best way The way to get the flow out was by piercing the cap.
Very risky but using good materials it is possible, I will be aware of the market in case aluminum lids start to be manufactured.
I decided to use a 0.40 (1mm) flow restriction at the inlet of the first filter and the second mounted in series, this cost me a lot to decide to do but I had a clear objective which was to increase the oil capacity.
The vehicle is an Audi A4
2.0 TDI EA 288 euro 6, and has many problems with the dilution of oil by diesel
The driving profile is a very efficient style and average distances of 26 km there and 26 return, the oil temperature barely reaches 85° in winter and I suspect possible water condensation.
The return of the oil to the engine is at the oil drain plug, I was looking at the possibility of returning through the oil filler plug but this car has a valve cover with a PCV valve and there is a risk that the oil flow mixes with crankcase fumes
