Do a compression check and let us know the results. You are looking for values that within 10 points of each other. Preferably lower. Also a new D16Y(x) series engine would show 200kpa per cylinder. Depending in milage expect lower values but as long as the values are close to each other you should be fine.

However if values are below 185kpa per cylinder then conduct a leak down test to determine where the compression is bleeding off at.
