BlowBy Filterbox for MANN&Hummel LC7001

thingiverse

the original MANN&Hummel ProVent100 is too big in my case so I designed an own box, smaller and without blowby-valve but with 6mm connection to control and adjust the pressure into the Crankcase. Version4 has 8 threaded rods and is a little bit wider, version 5 is maximum narrow and has 4 threaded rods. Additional you need: 2 x connector 1/4" x 10 mm for blowby inlet and outlet 1 x connector M5 x 5 mm for measuring crankcase preasure (if you like to) 2 x screws M6 with sealing as Oil drain plug 2 x wood-screws M6 for fixing the box into the engine compartment 1 x MANN&Hummel LC7001 and/or own filter 3/4" 4(8) x threaded rod M4 150 mm 8(16) x nuts and washers M4 Dont try the short way by using shot screws to fix the cover directly at the flange on top - this will give too much stress to the layer. Tighten the cover screws crossover by hand with a nut until the distance between cover and box is rd. about 1,6 - 1,7 mm (check it with feeler gauge) If you use the MANN&Hummel LC7001, first set the model to Z=-54mm and print rd about 10mm to check, if the filter will fit. If not then adjust X and Y for a perfect fit - tolerance is small!
