Hi! I recently pulled my 03 4.0l sohc engine out to replace the timing chain cassettes. But my ? Is before i fix them and install the engine and link everything up i want to make sure i have no bent valves or anything like that. I still have the chains on and as far as i know it did not jump time but i want to be possitive i have not bent a valve or if i could have can i still replace it with engine back in?. So what would be the best and easiest way to find out? With the engine out? Any help thanks!

 

Just do an engine compression test.
