'87 GN changed oil pan gasket ,bearing seal and valve cover gaskets which were cork but as hard as rocks. Have a slight leak in the front maybe timing chain gasket or oil filter seal. What usually fails in this area. Stock engine 145k. Thanks guys for all the info you provided.
 
You need to pull the front cover, buy a timing cover gasket set, do my oil mods, replace the timing set (then drop the pan when you see the missing timing gear teeth, get a timing set and an oil pump pickup while you clean out the broken gear teeth).


The above is not an opinion.
 
Timing chain replaced by previous owner. Upteen years ago. Thanks for your reply. Didnt see any broken teeth in oilpan.
