Please do! I'll be gone to FL for July and August for cancer treatment but other than that I'm around.

The large fitting gets JBWeld-ed into the upper oil pan and connected to a standard AN-10 turbo drain fitting with stainless braided hose. The smaller fittings were made for my catch can drain hose which uses -6 hose.

Since these are essentially zero pressure applications, my tolerances are definitely good enough - though obviously not mil-spec.

that early adapter worked for a while but i have since welded an AN10 bund into the side of the upper oil pan. as for the blow-by port i did some testing and found the stock port is too restrictive if you plan on running more than stock boost due to the ring end gaps being so loose on these engines. as such i drilled two holes in the upper plenum behind the oil separation baffle in the valve cover and ran two AN10 lines to a oil vapor separator which discharges into the bottom of the valve cover by the timing chain hump. the blow-by is the sent to an extractor venturi in my down pipe. something interesting to note is that a lot of the generic OM617 oil leaks stopped once i had done this it seems the stock case pressure management system is insufficient to prevent some build up and thus pushes some oil out various seals.

I'm glad to see someone else porting their manifolds, those stock castings are mediocre at best.

I'd really like to hear how the cam turns out, that's the one bit I haven't looking into yet. Do you think it will harm the street manners?

Um - what are street manners?

(Not part of my agenda.......)

the stock cam is kind of ridiculously bad. not so much if you consider the stock port size, geometry, and manifolds plus the early t3 turbine but once you remove those restrictions it becomes a major limiter. the stock lift is something like .313/.325 with duration @ somewhere around 230*. the rockers are almost the worst part of the problem i will give them credit the carbide facing with the hardened cam solved a lot of issues with that set up but the stock ratio is 1.05:1 with no real room to improve that or even integrate a roller element to allow for bigger/more aggressive ramps.
