TonyAus Posted September 30, 2019 Share Posted September 30, 2019 Having been plagued by small oil leaks I'm about to drop the sump on my 25 DB with a view to replacing the gasket. The 1.5mm bonded cork gasket I originally fitted doesn't seem to cut the mustard so I've decided to go up to 3mm. At the same time I intend to replace the felts but cannot remember what sizes I used last time . Can anyone help me with cross sectional dimensions for the felts used at the front and sides of the sump and the one which is glued to the rear main bearing? I intend to source the felts locally - yes I know Myers have them but postage to Australia is a killer for such a cheap item. Thanks in anticipation.

Spinneyhill Posted September 30, 2019 Share Posted September 30, 2019 When you drop the pan, make sure the top surface is dead flat like the machined bottom of the block is. Don't tighten it too much or you will bend it again. Also, on my DC, ALL the sump bolts have one end in the oily zone inside and one in the air below. It is almost impossible to keep the oil in the sump - it leaks out the bolt threads. Link to comment Share on other sites More sharing options...
TonyAus Posted October 3, 2019 Author Share Posted October 3, 2019 Bump. Dimensions for felts please. Anyone? Link to comment Share on other sites More sharing options...
MikeC5 Posted October 3, 2019 Share Posted October 3, 2019 Hi Tony, I didn't measure or photograph mine when I did it a few years ago (using Olsen's gasket set). I have a photo of the pan when I removed it but the felts stayed on the block. I don't think this photo will help much. You might try Myers and see if they would be willing to take dimensions for you. I think they'd understand that shipping them wouldn't be worth it.

RichBad Posted October 4, 2019 Share Posted October 4, 2019 Unfortunately I didn’t measure any on my recent build but checking the block, the rear bearing slot is 10mm wide. Not sure if thickness but I think it was square. Link to comment Share on other sites More sharing options...
24 Roadster Posted October 6, 2019 Share Posted October 6, 2019 I have felt for the rear main that I have not installed on my 24. They are 1/2 inch square by 8 inches long. The length has to be trimmed to fit. Link to comment Share on other sites More sharing options...

Mpgp1999 Posted October 7, 2019 Share Posted October 7, 2019 My oil pan is leaking like a siv it has new felt gaskets it leaks from one of the oil pump bolts. And along the pan edge where it meets the block. Link to comment Share on other sites More sharing options...
