I need to take care of an oil leak before Spring that I was afraid was a rear main seal but after having the tranny out it fortunately turned out to be just a pan gasket so what do you recommend? I typically use the cork gaskets and glue them down to prevent them from squishing out but hate doing things over again so is there any better options out there? Looks to me like just dropping the steering linkage will allow me to remove the pan (69 Charger)????

747, I don't know if you are running a wind age tray or not, but this wind age tray gasket combo looks like it would work very well.

No windage tray, I'm a bit hesitant to run one now days with all of the cam issues and would rather have plenty of oil being splashed on the cam instead.

Thanks, your link did however lead me to there single rubber gasket that looks pretty nice.

You should use a windage tray. Oil does not splash the cam, it splashes the crank, which you don't want to do that.

Maybe before I fix this leak I'll read up on this, I know a windage tray is meant to keep the oil from being flung around by the crank but with one you'd be relying on the excess oil from the mains and rods. Like I said I'll look into whether or not I want to add one. Thanks
 
If your rod and main bearings are that bad cam lubrication will be the least of your problems. All A, B & RB's oil from the bottom up mains, rods, cam, rocker shafts and lifter all by oil pressure from the oil pump. The crankshaft should not be picking up oil from the oil pan. It causes oil airreation and will turn your oil into worthless crap in short order.
 
I used that Jegs one piece plastic tray and gasket when I replaced my oil pan (engine in car), works perfectly and its reusable.
I didn't want to lay under there with two gaskets, a windage tray, and oil pan trying to get everything lined up, glad I used it, a year now and no leaks.

I'm well aware of how a Big Block Mopar oils, when I put a motor together one of the first things I do is study the oiling system and make sure it's fully cleaned. Anybody who knows anything about cams knows that they rely heavily on the crankshaft to sling oil on them (the lobes), read the cam break in procedure carefully. They want rpm's to get plenty of oil on the cam and where do you think the oil that get's pumped to the mains and rods go?????? Does it just disappear??? It runs out the side and get's thrown on the cam even if it's a brand new motor geez.

I was just recently talking to a cam expert on a possible cam swap in my motor and one of his biggest concerns was idle time.............. Why you might ask........ Because while idling your crank isn't getting much oil to the lobes.
 
And may I ask just what affect do you think a windage tray is going to have on oil seepage from the crank and rod bearings? I am not worried about low oiling at low rpm's I have also done my home work. I also have no idea why you think it is so great to have the crank throwing aireated oil all over the place it is no wonder you are worried about oiling problems. I have been building engines for over 40 years and have not had a cam fail yet due to lack of oiling.
 
Here's one link for you and I can find more if you would like. I may not have 40 yrs under my belt seeing how I'm not even that old but I tend to read up and have heard both sides of the story. Reading post 6 I really don't know why we're having this conversation "I'll read up on this" translates to I'll look into maybe adding one. It's your approach that's the problem, I'm always open to advice but not when somebody has to be rude about it (pointless). So lets get back to the question asked, what's a good pan gasket.

747....The windage tray will not stop the crank from flinging oil upward into the cam. It does stop oil from flinging down into the pan. When oil is flung down into the pan from the crank (without a windage tray) it carries a small amound of air with the oil droplets and areates the oil in the pan. When you have areated oil in the pan, it cavitates the pump and hinders it from picking up the proper amount of oil. Kind of like trying to drink soda from a straw with a pinhole in it.

The intent of the windage tray is to have a surface for the oil to hit so that it dissapates the air and runs back into the pan as pure oil droplets....something the pump gan make really good use of. Adding a windage tray will do nothing but benefit your engine's performance.....and stick with a high zddp oil to keep from wiping the cam lobes....that's the root of the problems with todays oils.

Thanks, I'm using a Lucas additive that's specifically for flat tappet cams so I'm good there. As for the tray I'll likely add one, everything you guys are telling me makes plenty of sense I was just leery after some of the reading I've done.

never use cork gaskets, they are rubbish, I have used these fel pros many times and never had a single oil leak.

I like this one (rubber with steel core). Thanks Benno
 
I used the composite one with the rubber seal molded into it like shown in the link on post #2 above on my 512 stroker. I put a girdle on my bottom end and the motor builder used every other pan bolt hole to directly tie the girdle to the block. His theory was that the girdle is directly tied to the block that way vs loosing some stability through crushing two sets of gaskets. Regardless, I like the fact that I can go a little tighter on the bolts to crush the rubber o-rings. I ended up making some 1/4" x 3/4" reinforcement plates to go on the outside of the pan rail so that I still got decent compression on the pan gasket while only using every other bolt hole. So far....so good, but I don't have hardly any time on the engine.
 
when I worked at the IH truck dealer, one of the old time mechanics would use Permatex weatherstrip compound on the oil pan cork gasket. It was a mother to get back off, but he never had one leak.

That's basically what I do with the cork gaskets only I use Permatex #2 and install it only slightly slug then come back the next day and torque it down but have also used the glue type with good luck. Don't know why it didn't work this time unless I never came back the next day????????????? Wouldn't surprise me with my memory.
 
Have had good luck with philpro rubber and cork with just enough silicone to hold them in place.
