EvoDunc Posted October 3, 2006 Share Posted October 3, 2006 On replacing the sump, what is the best seal to use. Is there a gasket?.....silicone? Link to comment Share on other sites More sharing options...
SimonMac Posted October 3, 2006 Share Posted October 3, 2006 Stay well clear of silicone! if it gets into the oilways or pickup it would be a nightmare... You can cut down and use the wet sump gasket (assuming you're dry sumped) or use an anaerobic sealant instead. Link to comment Share on other sites More sharing options...
CageyH Posted October 3, 2006 Share Posted October 3, 2006 Rover sump gasket fits. It is about £32. What is wrong with the old one? Only dead fish go with the flow.... Link to comment Share on other sites More sharing options...
EvoDunc Posted October 3, 2006 Author Share Posted October 3, 2006 Got a leak so sump may need to come off. Link to comment Share on other sites More sharing options...
CageyH Posted October 3, 2006 Share Posted October 3, 2006 Remove it carefully, and you should be able to re-use the old gasket. Sump should be low pressure, so just make sure the joining faces are clean when you refit it. Only dead fish go with the flow.... Link to comment Share on other sites More sharing options...
Rob Walker Posted October 3, 2006 Share Posted October 3, 2006 Caterham recomend using silicon sealant onthe Dry sump pan. I have always used RTV silicon without a problem. Bathroom quality sealant is not up to the job as it dissolves on contact with oil. The best stuff to use is the Ford black silicon sealant used on the Duratec engine, this stuff is unaffected by oil contact. Link to comment Share on other sites More sharing options...
EvoDunc Posted October 3, 2006 Author Share Posted October 3, 2006 Thanks Rob............that`s interesting. I was a little concerned after reading the above post re silicone as it looks like that is being used at present. Link to comment Share on other sites More sharing options...
7 wonders of the world Posted October 4, 2006 Share Posted October 4, 2006 If used correctly a silicone sealer is perfect for the job, the problem lies with 'builders' using too much. I use the VAG white version, a 1mm bead all round and it's perfect. If your inexpireiced then play safe and use a anaerobic sealer. Link to comment Share on other sites More sharing options...
Allen Payne Posted October 4, 2006 Share Posted October 4, 2006 My sump pan was sealed with an anaerobic sealant by Dave Andrews and it's never leaked. Link to comment Share on other sites More sharing options...
elie boone Posted October 4, 2006 Share Posted October 4, 2006 You should be able to use the sump gasket several times without silicone. If you take the sump off take the seal off and clean it with a rag also clean the block surface. There is a hole in the casting inbetween the startermotor and block that collects dirt, this dirt can come inbetween the gasket and the block if you don't take the gasket out and clean it you could end upwith an oil leak.

Support Team Shaun_E Posted October 5, 2006 Support Team Share Posted October 5, 2006 Loctite 574 is the stuff you need. Yellow SL #32 Link to comment Share on other sites More sharing options...
Kevsta Posted October 5, 2006 Share Posted October 5, 2006 I agree with anyone who has said anaerobic sealant (loctite 574...get it on ebay for a bargain and use it when needed). Having have silicone sealant in my engine (blocked oil galleries to cams...not done by me might I add) I know how silly it is to use on an engine!. I use the 574 on my sump...no leaks!
