Question about 1991 Mercury Grand Marquis
Sometimes if you are lucky you can tighten the covers and they will seal. Easy does it with a 1/4 drive ratchet and a small extension. You will need a small wrench to get the bolts with mounting posts on them for the wires. You will see what I mean when you do it.
I would start in the middle and go up one position and back one position until they are all tight. The other easy way is to take it to a shop. Myself, I pay people to put exhaust parts on my own cars because I hate exhaust work.
You will know if your covers still leak after you tighten them. All the screws will have to be fished back into position and a gasket replaced if you take the covers off yourself. But there is no rule making you do both in 1 day or 1 weekend. You can use ATV and make your own gasket too. Good Luck on what you decide.
