Sandy Posted December 27, 2008 Share Posted December 27, 2008 Car is an 01 SLR Had the engine out last year and the sump gasket on passenger side leaked afterwards. So, dropped sump, replaced gasket, heli coiled a few threaded bolts Oil leak is just as bad - if not worse? everything was dry yesterday before a 50 mile blat and now the passenger side sump gasket is covered in oil and its pooled and dripping from 3 places so not an insignificant leak! Anyone recommend what I should do next? Replace the sump? Have this one skimmed (have they been known to warp?) If I were to get my current sump checked, where can I take it or send it off to?

6speedmanual Posted December 27, 2008 Share Posted December 27, 2008 Sandy Rather than send off to be checked, you could clean everything up and assess wgether the pan is sitting flat against the block or whether it rocks or has gaps. You might also consider sealing the pan with rtv sump sealer as this, when applied to thoroughly degreased surfaces, forms a highly oil-tight seal. (there will be some on here who don't agree with this as there is a risk, if applied excessively, that globs can get inside the engine) Peter 6SpeedManual *tongue*There's no such thing as too much BHP per Ton 😬 Link to comment Share on other sites More sharing options...
Stuart Faulds Posted December 27, 2008 Share Posted December 27, 2008 The K dry sump shouldn't have a gasket - it's sealed with silicon, or loctite 574 for the more paranoid/careless. Link to comment Share on other sites More sharing options...
6speedmanual Posted December 27, 2008 Share Posted December 27, 2008 Ah, thanks for the clarification. Not having removed my K dry sump, I took it that a gasket was specified as per original post. I have built many engines now (even old designs) where oil sealing gaskets have been eliminated with good results. Sump sealer is the way to go.

Sandy Posted December 27, 2008 Author Share Posted December 27, 2008 We did consider using sealant but there is very little 'meat' around the oil pick up to get a good seal. Maybe I will have to bite the bullet and give it a go. CC however advised they use a modified gasket Link to comment Share on other sites More sharing options...
oilyhands Posted December 27, 2008 Share Posted December 27, 2008 I have had over 50 CC dry sump engines apart and have never seen one with a gasket. They are usually carelessly sealed with excessive volumes of RTV. The correct sealant to use is Loctite 574, not because of paranoia, but because of the very real danger of the oil pickup being clogged up with excessive RTV sealant, I have seen this on a number of occassions and the result is big-end failure.

Englishmaninwales Posted December 27, 2008 Share Posted December 27, 2008 A wet sump gasket trimmed to the dry sump flange works well, is leak free and is reuseable. Link to comment Share on other sites More sharing options...
