Im useing a milodon oil pan #30950 for my 540. Has any of you guys used a 1 piece oil pan gasket with a milodon pan? I really could use a part number of the gasket if you have one?

Thanks Rich

Rich,
Fel-Pro #1884R should work with the Milodon pan, if you're using a MKIV block.

Thanks Bill,

Im curious, what clutch are you running in your ride? 5.57s WOW!

Thanks again Rich

Not to hijack, but would you happen to know the part number for the quality one piece felpro oil-pan gasket ( i think they might have had it in superchevy a while back) for my large journal 327?

WHoa... thems some tall gears.....

I thought that I heard that onepiece gaskets weren't for performance use. Anybody else heard of this? I need to change my gasket too so if they're ok anybody know of the best brand to use?
thanks,
Dustin

I used the exact same Milodon oil pan on my 540 Merlin III block...the FelPro 1884R fit perfect. graemlins/thumbsup.gif

Hey Bill,
I am trying to use the gasket with a Moroso pan, and it looks like it is just too thick at the 4 corners where the pan comes down...I am using studs and I can tighten them down and the gasket will squeeze at those spots.

Did you have the same problem? Also using Merlin III block.

Thanks

The only problem I had was the dimples on the bottom of the oil pan weren't quite deep enough to clear the stripper tray/main studs. A ball pein hammer on the dimples easily fixed that.

It figures smile.gif
thanks man.

Rich,
I am running a McLeod B&B/Long style clutch with a Hayes disc. Put the 5.57 gears in a few years ago when running at some 1/8 mile tracks that have marginal traction. They are a little too tall for 1/4 mile, but 5.13 and even 5.38 works well there. Car is long rod (aluminum), high rpm, combination.

Bill,
One more quick question, did you use any sealer any where on the one piece gasket. I have a tendancy to use a little too much sealer because I hate oil leaks, Im just not sure on this one. Tighten it up from the inside out, your thoughts on installation?

Your car sounds like a screamer!

Thanks Rich

Rich,
Best bet is to not use any sealer, especially on a rubber (silicon, etc) gasket. Make sure that the gasket surfaces are clean and straight. Tighten the pan gasket just as you would a head gasket, in a circular pattern. Begin with one of the middle bolts, then tighten the one next to it, then go to the adjacent bolt on the other rail. Keep going back and forth from rail to rail until you reach the ends of the pan. Once you go through this pattern, start again at the same bolt that you started with and go through the entire tightening sequence one more time.
If it gives you peace of mind, you might put a very small amount of sealer at the four corners of the pan where it meets the timing cover and rear main cap. Don't use silicon sealer or RTV because it is slippery and might allow the gasket to slip out of place during tightening sequence.

Bill,
do you torque the bolts down? I have studs, they are 1/4" and I am thinking torque the nuts to 12 ft-lbs...
Does this sound right?

I have also heard that puting some sealer on the 4 corners will not hurt. Will some non-hardening sealer, like ARP's work?
thanks.

I use Fel-Pro's one piece on my SB but this should apply. The instructions that came with it said to use a small amout of silicone on the corners. I did this the first time I use one. however, since then I do not use any. No leaks and the gasket is reusable (3 times, as of now). With the silicone, the rubber was torn a bit taking the pan off, making it unusable. I'd recommend not using any sealer. Just clean everything with brake cleaner or lacquer thinner. 8 Lbs of torque is right for the 1/4" bolts, 18 lbs for the corner bolts.

Pat,
did you have any problems with the thickness of the gasket in the 4 corners being too large and not letting the pan to sit down all the way?

Also, do you torque the 2 timing cover studs/bolts to 18 ft-lbs?

I am wondering if I have the wrong gasket, maybe a MK V or VI?

Thanks

Can't help on the BB, mine is a SB. However, I had no problems with the corners. With the pan just setting on the block, it looked like the gasket was too thick at the corners. Once torqued everything was fine. The timing cover bolts on the SB are 1/4" so 8 lbs is what they got.

Also, to insure the gasket is compressed evenly, go around the pan several times with the torque wrench until all the bolts hold the torque you want. Might take 3-4 times.

Cool, that is what I am talking about...I think it is suppose to be this way and once it is torqued down everything gets in place.

I will go over it a few times starting in the middle.

Thanks.
