SIngle relief case mods for better oil pressure VW Flat 4 Air cooled

[@jacquespoirier9071]

a major aspect that is not covered, these engine had no oil filter, to my experience, oil and air filtration is a major component of an engine durability. Oversizing the oil channels can help somewhat for a substainer high RPM use but it is the particules carried with the oil flow that are mostly responsible for engine wear. On cars where I installed a 1 micron bypass filter to complement the full flow filter, I almost doubled the engine life. I believe firmly that the addition of full flow and bypass filtration on these engines will do more than oversizing the channels for durability of a street used engine. good effort very good explanation very good video

yea for sure I will be putting on a spin on filter along with the full flow oil cooler

Hell yeah sweet. This will help me with my first engine build. I bought a used bus case for my bay window. Hoping to use it and build a 1904cc

[@OwhyeeVdub]

I asked about this type of build not to long ago. I really want to make a few of these for our rigs.

I think you misspoke. When the oil is cold it's thicker and the pressure is higher, which pushes the plunger down so oil flows directly to the lower supply line. Once the oil is hot, it thins decreasing pressure, the plunger rises, and oil is diverted to the cooler.

[@Mikefngarage]

flows through the cooler first. then once it reaches full pressure which it might do fast when the oil is thick pushes down the plunger and flows to both areas. Cooler always goes first.

Wish I'd said that. 😊

[@mghuertas]

I have never think on what you said the pressure its different on other oil passages👍

[@firealva41]

Been looking forward to seeing this build

[@benshore7357]

Looking good 🎉 always like the engine videos

Thanks Mike

Mr. Mike. I have a question. You said 76mm crank you may not have to clearance anything but what about a 78mm? I want to build a 1879cc and people on the samba are saying it’s a mistake you can’t use 88mm pistons on a stroker. But I’ve seen you do it by just cutting off the piston skirts. Anyway what advice you can give me on this like rod length n stuff like that and in your opinion is this possible? Also where I live I can’t find a machine shop that do inline bore vw cases is it necessary to do that ? Thanks.

[@benkanobe7500]

3/8inch = 9.525mm

[@truthboomertruthbomber5125]

Look at Nissan 200SX turbo pistons. Very small compression height. Even with an 82mm crank you will need long rods. Std bore is 85 or 85.5 or 86. CRS. Bore stock 1600 cylinders to fit. 10 cc dish iirc.

Hey Mike ! on that case the first thing to do is check the hole that is under the oil cooler mount . In side the oval hole there it will crack ? Go with a 30mm Schadek it measurements are closer to a real VW , so many aftermarket ones the size of the mating surface aint right . Mike did you see CTs 914 build with VW Darren , man if you had that in the bucket truck and a .002 trans you would be able to run with traffic ?

[@Mikefngarage]

then stopping it.....needs more braking power

[@jimmywilkinson9190]

Yeah thats true you would need brakes from a 71 up . If you could get a wrecked 74, 75 , 76 parts are parts .
