Pro tip, buy a couple spare valve keepers with your springs, one is in the bottom of my oil pan
Turbo fits nicely with benzforce adapters, i would just go benzforce 100% for this he221 setup…keeper(s) is coming in today, i intend to button the head back up before redoing and welding the Down pipe.

I ran that setup on my e300, (without the adapter parts, just welding) great driveablity but a little smokey for my taste, your inter-cooler and exhaust might flow better then mine and i def needed the valve springs so yours may turn out better, there is a version with a billet wheel that is 1.5mm larger hopefully thats the one you got. Measure the ID of that 12an drain. I've seen some issues with that being too small and making the turbo burn oil, I prefer barb drain with hose personally, alot more flow and cheaper. a drain for a TD04 works. and on the block side a 5/8 heater hose barb for a small block fits right into the stock drain if you bore out the hole and tap it 3/8 npt.

In hind-site i would have gone with a billet wheel. Didnt see that option… jusy curious why did you need valve springs? I was going to drop to 10an for some clearance, surely the tiny restricter in the feed line wouldnt allow that much oil to build up in the return?
So your 1.5 ecu with this turbo overfueled? Did you have an egt gauge?

Yea they removed the billet wheel from their site but you can still find genuine ones sometimes on ebay. I was floating valves at high rpm. Depends on what restricter size you have. I ran with a large 2.5mm restriction and a large ID drain and no problems. The restricter topic is debated somewhat, im in the camp of i want as much oil flowing though the turbo as possible without causing issues when it comes to journal bearing turbos. Pretty much every factory turbo system has a larger ID more free flowing drain then AN fittings allow. Yea the 1.5 tune was too much, you can use different map sensors to tune also, i was running a 3bar, the higher pressure sensor you use the less smoke i could never get a 4 bar to work for some reason. I had him turn it down twice but never got it where I wanted it, sold the car to my friend that doesn't seem to mind. Id probably sell you my chip programmer if you every end up needing it.

I am following all this. I have a 1992 that will be getting an OM606, fully mechanical, after a while. I have one in my daily driver, a 1998 E300, and have been driving Benz Diesels for almost 20 years now!
