Yep there is some blow-by, but it is very minimal.. No leaks under the car, but can smell oil in the exhaust. That makes me believe that the valve guide seals are bad, and also I guess the car the engine came out of sat for 13 years of reasons I don't know. (engine is from a 1983 760 that was totaled that had 140,000 miles on it) Interesting thing is the engine is an 1985 and looks as to been rebuilt at one time as the con rods were marked, cylinder bores looked great. But I did notice some oil on the valve stems, it did not concern me at the time because I thought it was oil from the the seal on the turbo was seeping on the compressor side. Now with the new turbo and still there is oil consumption, car sitting for 13 years and seeing oil on the valve stems makes me think the stem seals are bad.. I will find out. I'm building a tool to compress the valve springs with the head on the car.

If it's just the valva guides seals it's "ok".
i hope for you it's just that. Could it be a piston ring wich is stuck ? the tool you are working on is interesting. It would be very cool if you gave few pics of it when finished. i did one to remove the valves but once the head off the car. it's ugly but works good.

I will give pics of the tool when I'm done, It should be able to do the whole family of VW engines (1.5,1.6,1.9,2.0 ect..) that have the similar valve train.

Well, I pulled the head off the engine. It has been rebuilt! It is .5mm over and pistons/cylinder walls look great. Walls are polished but not worn. I'm not sure where the oil is coming from. Compression test @65 degrees block temp gave 365-400 psi. I think the head is the problem. I have my other engine cleaned,honed,painted, new main bearings installed and crank in. I'm waiting on the Deves rings from CPD and will be rebuilding the head this week. If the rings come in before friday I will have the engine installed this weekend, hopefully get some miles on it before the swedish car show.

I'm sure you could have better compressions with warmer temperatures.
It's always cool to find the engine rebuilt when you open it

I'm very curious too, It was my first porting job, I didn't spend too much time on it as this motor is only to get the car back on the road.. My next motor will be a little wilder. I didn't have the time to do this motor how I want, But it will be a nice motor when done.
