Yes posting more information can be helpful in providing you with better solutions. If you have a 1.8t engine and you developed a sudden no compression engine then your camshaft timing might be off/jumped and it may have damaged some of the intake valves in the cylinder head.
If the camshaft chain stretched and its tensioner failed possibly due to lack of oil pressure then the camshafts might not be timed to each other.
This can be determined by visual inspection after removing the valve cover and engine timing belt cover. It could even be an engine sprocket that has lost its alignment tab which caused some engine valve damage.
Go back to the basics and check the timing belt of the engine and confirm TDC with the #1 piston.
It should not be difficult to determine what is wrong and why it happened.
Good luck!
