2004 Oil weeping from upper oil pan

[Bigdog1949]

Has any one used stop leak in an Tbird ,Jag engine ??

I have - Blue Devil Oil Stop Leak....it works if the leak is merely weeping past an old seal. It swells and restores old rubber seals and after several hundred miles will stop the average leak. Also used it in my 1963 Corvette. Is it the "be all/end all" way to fix a leak ? E.g. reseal the motor ? No, but it may solve the problem for years; its cheap and its harmless.

There is NO downside to trying it; this is not the "old" stuff from decades ago with pepper like particles to flow into a seal defect and possibly clog an oil passage.

HOWEVER, if the upper oil pan has bolts holding it (I don't know for sure) it wouldn't hurt to snug them up a bit as well.
