Old D4 4400 engine puzzel

My crystal ball is a little cloudy but it sounds like the inlet valves are not opening based on the lack of intake suction. Possible cam timing, and/or compression release issue. I have a D4400 and it spins over by hand very easy with the compression release in the start position. In run it will stall the pony if not careful when engaging the clutch. I have attached a scan of the page from the engine manual detailing how to remove the compression release as it is not a straight forward procedure.

Check your engine timing for TDC and flywheel marks. The D4400 flywheel can be mounted out of position unlike the later D315.

OM I,m pretty sure you still could get the D315 off too and it wasn,t till the D330 that the flywheel had an offset hole so you couldn,t get it on wrong.

Valves are .15/.10 or is it .015/.010?

I have the Cat spec sheet and yes the valves are set .010" hot and at the dealer I (we) always set them .002" more when cold or would be .012" cold but it,s a good idea to check them if you want when the engine is warmed up.He just didn,t get his decimals written as should be as the "0" has to be in there after the period.

Old Magnet, you seem to have gotten right to it. When the TDC mark is coming up no. 1 exhaust is just closing. If I remember correct I can just turn the flywheel 180 degrees to get it right without taking the injectors out again to find no. 1 TDC. Am I correct? It is a bear to turn by the fan all alone with out the compression release working.
Also to the gentleman who sent me the pictures of the compression release. The picture will not enlarge enough to be able to be read how to dismantle it for inspection. As I remember it is not adjustable so perhaps it is best not to take it apart even, at least until the timing is corrected.
Yes I had the decimal wrong, valves are set at .015 cold to recheck and set at .010 after running.
Sure do thank you fellows

If #1 exhaust is just closing the piston should be at TDC on the exhaust stroke. (providing the cam timing is correct) Therefore you should have to turn the engine a complete 360 degrees to arrive at TDC compression.

Well fellows, Old Magnet must have extraterrestrial knowledge about these things to have come right to it that the timing may be off. It sure is some blessing to have him with us. The old 4400 engine should be in time now. It seems the flywheel can be off in any of the holes and not just 180 degrees off.
Now I just need to know if there is anything that can be done about the compression release that does not relieve compression and does not work on any of the other two 4400 engines here. I understand it is not adjustable.
