Just got the car running right again and after driving it for a bit i look under the hood and theres oil all over the passenger side of the engine, on the AC dryer etc. I just replaced the valve covers and gaskets, both the valve covers look dry, theres even more oil drenched under the car on the passenger side. I think the cluprit may be a bad timing chain cover gasket, i've wached it seep out from there before but never this bad, can valve covers still leak even if they look like they arent???
