The tools I've been waiting for have finally arrived, which means, its time for another upgrade to the prototype engine I'm building!
This time around, I'll be doing a 3 angle valve job and also adding a tube to connect the crankcase to the cylinder head. Hopefully, this will take the engine to the next level!

Just found your channel and I'm really interested in that pressurized oil feed/filter system. Excellent bit of engineering! Can't wait to see more on this!

As soon as you mentioned the crankcase breather, made me think of all the small engines I have ever worked on and non have pcv valaves. Great idea. But you need an inlet and an outlet on the crankcase. That way there is flow threw the case and not just vacuum. But cooling the valave cover to the crankcase by a tube are that same air. Am I wrong? The valave cover has pushrods inside it open to the crankcase. So that air is one and the same.....

Hi, I later added another tube from the crankcase to the head cover. It's sort of the same air like you said but the pressure build up within the crankcase is always very high, so extra tubes will help alleviate the pressure much better. In practice, you are looking at much quicker engine response and acceleration.

Nice. Is that a Lo206? I’ve never seen that oil filter on a small engine like that. Does it have an oil pump now?
@JSRacing-Kartsmith

That’s right, it’s actually a 3 piece package. The case cover has a dedicated engine oil feed that goes through the crankshaft and directly lubricates the area where the connecting rod attaches to. The connecting rod is also reinforced and has bearings on it too. We will be making billet versions of this in the near future.

They probably sell the same stuff there, I didn’t buy it from aliexpress. Either way it’s very cheap.
