First time post. 2023 cx5, has cylinder deactivation. Bought new. 4cyl non turbo. Engine had an oil leak which was determined to be a hairline crack in the block. Engine replaced under warranty. When the car was returned we noticed a slight shake in the floorboards only when the car is sitting idling in neutral. Shop is not having luck locating the cause. Anyone had this problem or any ideas?

Where was the crack located?
First thing people will think is motor mounts. They need to be sitting right and torqued correctly under load. Someone who has actually worked with them could provide more info.
Car has 37000 miles on it so motormpunts should be good.
Crack was on rear of block

I didn't say the motor mounts are likely worn—read carefully
You can end up with vibrations from taking an engine out and putting it back in.
Rear main seal area?
yes it was the rear main seal area, close enough to look like a rear main leak. The mazda tech did check the motor mounts and tried adjusting them but no change. The trans was removed once also when they were going to replace the rear main seal.
Thanks for the reply N7turbo. Does it make sense the vibration only shows while at idle in neutral?
anything to do with c/d ,or from excess pressure internally,?thanksI didn't say the motor mounts are likely worn—read carefully
