[QUOTE=BiGEZ;10460767]There are some seals in the valve cover the goes around the spark plugs, these get hardened over time due to heat and cause oil to leak into you spark plug wells.
Part number for the Toyota seals are: 11193-70010, you will need 8 of these.
Be sure to clean as much of the oil out of the wells before you remove the plugs.[/QUOTE

once i clean out everything and install the new spark plugs and the spark plug seals would i need new coils also ??

Again i appreciate all the help and input your giving me brother .
As per others, sounds that you should replace all seals on the valve covers... do remember, these cars are approaching 20yrs in age...!

That sounds to be the outer seal (on the edge), and the inner seal (around the plugs), and any other seal, such as something such as a pcv, valve, etc.

At this age, oil seals and suspension bushings are the first to go....

im going to look into which seals are bad and attack them one by one while i can , im trying to build my car slowly but surely . for now im going to focus on cleaning the motor up and changing the plug seals and go from there . i have already changed the suspension , front ball joints , got my camber kit but still missing some to buy the rest of it ... its expensive lol , want to get the diff bushings and all other bushings i can buy to make sure the car is running right . Funny thing is i bought the car as a daily and it turned into a project now i need another daily

Change the valve cover gasket along with the spark plug seals and that'll solve your oil leak. I recently did mine. If you know what you doing you can have it done in a few hours
