Well once again I need the infinite wisdom of the Cartalk community. Here’s the story: My engine misfires one night so the next day I check the spark plugs and there is oil in the far left plug well. I decided to change the valve gasket cover. Went to take off the covers and the cover wouldn’t budge. It ended up cracking some metal piece that I SUSPECT houses the timing chain. I’ve included several pictures of my engine bay so you can get a feel for how it looks. Not sure what the part that is cracked is called so I’m hoping someone knows. Anyway my real question is, is it worth it to replace this part and sell the car for around 1800 or just scrap it for about 500? If you need any more pics or info please let me know. The parts circled in red are where the crack is.
