Front main leak

[AndyB]

Is there a permanent cure to oil leaking from the front main on a Lotus Twin cam. It's not a major leak, just a drop each time I park for a couple hours or instantly if I'm autoXing.

Are you sure it's front main or instead the oil pan gasket? The latter seems to be the cause more often than the former.

Good point, I guess I gotta get it up in the air to see.

assuming it's the oil pan gasket - here are a few things you can do:

 

Install studs at the corners (http://lotus7.com/PUSHROD_PARTS.html - see bottom of page)

 

Use rubber seals if possible (http://www.lotuselan.net/forums/lotus-twincam-f39/cork-rubber-t24330.html - I suggest reading this whole thread - good info)

 

Use a high quality sealant, but use it sparingly. I've had good luck with permatex "the right stuff" http://www.permatex.com/products/our-brands/the-right-stuff
