All the timing cover seals need replaced 3 of em & since your there replace the Cap & Rotor, Plugs & Wires since your there Also clean the Opti sensor & replace the water pump ITLL cost way more BUT Save you in the long run Been there done that
Learned the hard way & then had a buddy that didnt listen either lol He done all of it eventually To get the heads off, i would remove the engine if you have room. I made the mistake of trying to remove them with the engine still in the car.
