^ its an 83 258 with 92K miles (but like i said in another thread its been sitting for a good 5 years without being cranked)
and it was brought in to a shop a while back by my grandpa for valve cover leakage.
i'll try all of what you told me to do and see what happens. i've been using rotella 15 40 and lucas stopleak/oil stabilizer in it. and i've been checking the oil level every few days. it has gone down a LITTLE. not too noticeable though.
i cant remember right this minute but i think the valve cover is metal
anyways i'll try everything you said today and see how it goes! thanks for the tips upnover!
PS: i'll take a picture of the valve cover/engine in a little bit
