Valve seal issue? Anything else that could cause this? I'm just not up to this job, pull the head, try to get bolts out of exhaust manifold, been there for 25yrs, my luck the bolts would twist off and if they do then what? I'm about ready to just let the car go. Emaculate car, gave it to my 31yr old son who trashed it before he left this world. I finally got everything working again in the interior except the antenna not right. I just don't want to drop a bunch more money in it.
