So I just bought another 98 e300d turbo.  Wasn't running right. First found #3 cylinder wasnt firing after cracking each injector. So I took the valve cover and manifold off for easier access to injectors and was gonna pull glow plugs for compression test, anyway pulled #3 injector apart and cleaned (seemed pretty clean). As I restarted it with injectors all back I left the intake manifold off to listen. Before I could tell iff my injector clean worked I had the revs up and then the first port of cylinder #4 poped a burst of compression in my face and has been blowing compression out since. So questions.  1. Whats cause of valve not seating? 2. Whats good compression for these engines. I am pulling engine for superturbodiesel project.  What else should I do while engine is out of car? (Currently sill in car)

Something fell into that port and keeps valve open. Or valve is bent.
Wat is needed to recondition engine to it top condition will depend on inspection when you dismantle it.
Usually those engines if looked after will perform without need to open up to over 300 000 miles.
Depends on your goal of making power some parts may need attention. Like locking camshafts sprockets so they won't slip under high rpm changing valve timing.
Installing high output water pump is one of other easy modes.

1977 300D for parts? Just a pile of rust but still runs!
1984 190D 2.2 - gone to better home
1987 Dodge Maxivan with OM603 and Goran’s 7.5 backroads terror
1987 300TD - tinker toy
1989 300TE - parts
1991 300TE - backyards decor
1991 300TD - Barrote’s 7.5
1992 300TD - semi-STD(Goran modified 7.5 ip but still with factory turbo+at)
1998 E300TD - dd with DSL1 now
1998 ML320 - snow ride
2014 Sprinter 2500 - Malone’s tune + pedal box

Those engines have the nasty habbit of doing that? so run the engine for a wile! change the oil! inspect hyd lifters and timing. when compression is really bad is under 10BAR . engine exaust becomes white and failure of cylinders when cold. typical compression test should be above 18bar engine warm.

Anjay what´s the deal with the high output water pump? part number ? and manufacturer would be much apreciated

Ok thanks fellas. 
Barrote your saying that the valves do stick sometimes and to just run it until it stops sticking? 
And yes definitely interested in a high flow water pump.
its got 225,000 miles. My other 98 is my daily driver with stage 2 ecu tune, runs great with 218,000

More likely a pumped up lifter than sticking valve. Let it run for a while to see if it works out,

Yes, for a while. The valve moves heat to the head when it is on the valve seat. If it never touches the seat it will eventually burn. So don't drive it 500 miles. 80 miles at light load, maybe okay.

yep, when u see metal touching u´ll realize it quick enough.
the hyd lifters sometimes loose the oil lock ability, they come back soner or later , lets say driving a car a day long with multiplr stops and starts heating cycles it should disapear, if it doesn´t, got to remove the lifters clean them, check if integrity, sometimes they just crack where the cam lobe hits, and they can´t charge with oil leaving the engine , wisling.
the engine oil change thing is importante. even if u use 2/3 liters of cheap one for flushing, and then change for 15W40 or 10W40/50 for std apliances.
good luck

I fired it up this morning and it was back to normal. The engine does still run rough at lower rpm, I think ill test compression tomorrow.  Is it going to be a hassle to pull glow plugs out?? I also plan on pulling head later on while its out for freshening up head gasket, I bought valve springs from kmcams and just to check it out

test compression by injector wel.
glow plugs usually work well with plenty of wd40 and heating cycles.

When I last checked my compression just about all of them were right at 390psi. One was at 290 but I think the motor sat a while before I bought it. Once I drover it, it went back up. Figured you may want a PSI reading since you are in us.

Pulling out GP on OM606 and 605 is often problematic as they seize in and break off.

use imagination brother ,
u dont want to mess up with glow plugs unless u have too.
at last resort , u can use the injector itself, dismantle it remove the nozzle and thats it. or in junk yard any MB injector has the same treads, so build your own device.
psi , it can be as low as 250, no problema.

So I went for it and with great success pulled all 6 glow plugs to check them and the compression.  Compression was good between 380 and 400psi. I cleaned the threds and never seized them befor I put back it. I plan on putting new ones in when I pull the head off later on

I just want to add ever since I put water injection on my motor my glow plugs have never been so easy to remove. I think it also helps that I have had them out so many times checking compression on my motor.

Thread in the head is too short, so when you fasten GP to specified torque the wrench goes off, or your hand says "well thats enough" but in reality you just reached end of thread and conical seat does  not seal. And then its familiar story, everything get stuffed up with coal and there you go. This is fault by mercedes factory.

yes , u dont drive it , u let it warm . u do cycles of warming and drive carefully, the problem will dissapear.
or u can play the right way change oil , remove the lifters clean them fill them with oil, and it will be ok.
