1991 Toyota Celica All-Trac Q&A
1991 Toyota Celica All-Trac Question: Oil inside spark plug tubes.
The valve covers on that engine have a spark plug tube seal at each spark plug tube, they need to be replaced but the valve cover gasket and valve cover bolt seals need to also be replaced. About an hour labor $45 parts. Check valve clearances while the cover is off. - patrick mannion
