So many oil leaks.
Even had oil mist out the windshield defrost vent! What causes so much oil around the cylinder/case interface? Pretty wet on both sides.  Side where I attached the oil breather to air cleaner has built up oil on back side of intake valves!!  Have to figure out a better way for head and case vent. On a positive note, 6 8 6 6 % leakdown!! |

I do not know the science behind it, may be the aluminum heads and case mating cast iron cylinders with steel studs, but the head studs need to be re torqued now and then. Bugs had this problem, and it was easy to hear when the head studs had come loose. For breathing I have all three (two heads and the case breathers) running to something like this. https://www.jbugs.com/product/8544.html?utm...mRoCpqkQAvD_BwE |
