Damn really, I hope not. Why do you think that? It's on the top engine block side. Why would I have to drop the pan?

They tend to rust out and become difficult to remove. It is actually best to drop the oil pan if it is old and rusty. That way you do not get rust, dirt, crud, etc. down into the oil and oil-pan.

You are also going to want to polish up the hole it mounts into with a scotch-brite pad really nicely so the new one does not leak. Again, dropping the oil pan is the prudent thing to do as you don;t want any debris from the scotch-brite pad or the crap that was cleaned .. getting into the oil.


- My own opinon is that taking a shortcut by not dropping the oil pan to replace that gasket would be quite risky. It would be best to take the time to drop the pan, etc. Maybe take the opportunity to also do a rod/main bearing job if it is getting towards 800k miles on those components too while you in there?. - just some thoughts.

Last but not least.. make sure you have a maintenance free crank case filter.. or that it has been drilled out really well so that the engine cannot build up any pressure in the oil pan. Any pressure buildup causes things like the turbo drain line, electrical fittings, and other places on the engine to leak/seep oil. Any pressure buildup ion the engine also causes premature camshaft damage, turbocharger problems, and other issues too.
