Fixing my weeping sump plate
Unrelated to blowing up my engine I always had a wet and dripping sump plate. Just a drop here and there and all the stud ends had that 'I'm about to drip' bit of oil at their ends. Always aggravating...
So, I took a look at the sump plate and discovered that the areas around each hole were quite raised compared to the surrounding surface. This would lead to very unequal sealing on the gaskets. My expected fix (not finished with the motor just yet): http://forums.pelicanparts.com/uploa...1204049474.jpg Just take a nice long wide flat file and file away the high spots. You can clearly see that the plate is not even at all and around the holes were large raised areas (the exposed metal parts). I filed away enough to have a constant ring around the circumference of the plate. When you file, file across the plate or across two holes not adjacent to each other. This will keep your file flat. Took a while as I had a fine file. Not sure if I'll powder coat or paint it just yet, but I have high hopes for a dry sump area. Best regards, Michael |
Nice. You could also ensure the entire surface is perfectly plane by finishing it on a flat sheet of sandpaper taped on glass or marble.

Michael,
Just get one of these and forgetaboutit. :D This one is cast but our host has them in billet as well. They come with studs or bolts and will not warp. You have thinned the metal around the holes and they will deform easier next time you torque the plate down. Albeit, somone wanked on it previously.

I don't think it will re-warp too much. I probably took off maybe 0.025-0.050" so no structural issues. I actually don't think the plate was flat from the factory. Looking at the filing pattern it looks as if the plate actually falls away as it approaches the edge. I have seen this in some stampings before. With 8 studs it should be fine with the spec torque and I wont over-torque it as may have been done in the past. Still... your plate looks really nice ;) Best regards, Michael |
