'95 e34 still leaks in spite of new metal gasket

I can usually count on some solid advice from the users of this group: my 525 finally has a new gasket at 125,000 miles - and the thing still leaks oil! The shop (a good one) says the pan is warped and needs to be
replaced (400.00 plus labor) Don't they make a better gasket that will account for some imperfections in the surfaces to be joined?

Most mechanics would peen down the raised bolt holes on the flange where they have been tightened and caused high spots.
When a new gasket is fitted and the bolts torqued (if they were) then the high spots would meet the block first leaving the bits in between loose so oil can seep out.
Good shop - bad mechanic it seems.
The ONLY way to get a sump pan to sit on the block is if the mating surfaces are reasonably FLAT. Also a good coating of HYLOMAR jointing compound helps - use a silicon sealer if you wish - reduce any surface anomalies that can cause a leak.
Also make sure it isn't coming from the front or rear bearing /crankshaft nose oil seal. If the crankcase breathers become blocked or there is excessive crankcase pressure the neoprene seals will allow oil to seep past and drip or run along the sump pan and drip on the floor.
125K isn't a high mileage.
In relation to the "better gasket" it's a "BETTER MECHANIC" you need.
