Ok, to make a long story short, my 2012 Audi A4 quattro had a bad timing chain tensioner. So I changed the tensionner, the chain and most usual stuff (guides, etc). Then after I was sure the timing chain was correctly installed, I discovered that I couldn't turn over the engine. So I assumed I had some valves hitting the pistons while the engine was still running. I removed the head to discover the valves are perfect. So, still puzzled I started cleaning everything before reassembly. Cleaned pistons top #1 and #4, then I tried to turn the engine to raise pistons #2 and 3 and when the pistons reached the top, if I let got the crank nut, they are returning to the bottom of the block. I didn't tried to make a complete 180 degrees because I was afraid to break somehing.
Thats confirms that I removed the head for nothing, but why the engine won't turn over? I have no ideas? There are no head on it, no chain, ...
Next step, I will remove all chains and guides, but if that is not working, then I'm completely lost. Maybe I'm just too stupid about mechanic, but I don't understand.Any reason why a bottom end without a head wouldn't turn over? Any suggestions will be considered!
