Dave McCulloch Posted November 21, 2006 Share Posted November 21, 2006 I've searched the archives but can't find an answer to this one. I'm doing my first oil change since dry sumping my K series, and when I built it I fitted the blue plate with silicone gasket gloop as recommended in the instructions. After many hefty wallops with a mallet and drift, I've finally persuaded the blue plate to part company with the bellhousing, but how do I remove the layer of silicone I'm now left with? Tried brake cleaner and cellulose thinners so far with no joy - is there a solvent which dissolves this stuff? Hopefully won't have the problem again as I'll be fitting a Hellier plate with drain plug. Thanks Dave Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted November 21, 2006 Support Team Share Posted November 21, 2006 Probably easiest to use a gasket scraper. There is a solvent for silicone - I've seen it in B&Q for removing bathroom sealant. Yellow SL #32 Link to comment Share on other sites More sharing options...

Beelzebub Posted November 21, 2006 Share Posted November 21, 2006 Do a google for it It's fairly popular now & lots of outlets have it, such as Screwfix here Link to comment Share on other sites More sharing options...
Sheds Moderator Posted November 22, 2006 Share Posted November 22, 2006 I use a gasket scraper for all this stuff, or a paint removal tool for windows. Cost £buttons. Link to comment Share on other sites More sharing options...
TomB Posted November 22, 2006 Share Posted November 22, 2006 When I recently had to clean old sealer off my sump pan before mating it to a new engine, I used Nitromors paint stripper with gentle scraping with a small wallpaper scraper. Seemed to do the job Link to comment Share on other sites More sharing options...
Dave McCulloch Posted November 22, 2006 Author Share Posted November 22, 2006 Thanks all - picked up some silicone eater from Screwfix at lunchtime. Dave Link to comment Share on other sites More sharing options...
Paul Deslandes Posted November 22, 2006 Share Posted November 22, 2006 I would strongly suggest you don't use regular silicon sealant in this or any other oil related application. Its a bu99er to get off next time you take it apart and you run the risk of a small (or large) piece breaking off and finding its way into an oil way, with disastrous consequences. Vauxhall spares departments, and no doubt other manufacturers, sell a much softer sealant GM part# 90485251, that will only break up into very small soft pieces and won't cause a blockage and will get taken out by the filter. Its a doddle to clean off ands what's more it works as an excellent sealer. You can buy a Loctite version from Halfords Loctite 598. I expect Loctite make it for GM anyway. If you keep the cap on the tube it lasts for years. Just my two penny worth! Edited by - Paul Deslandes on 22 Nov 2006 17:50:45 Link to comment Share on other sites More sharing options...
Beelzebub Posted November 22, 2006 Share Posted November 22, 2006 Good point.I've seen oil pick-up strainers completely covered in this stuff caused by over zealous application. Link to comment Share on other sites More sharing options...
Sheds Moderator Posted November 22, 2006 Share Posted November 22, 2006 Agree absolutely. I seal my blue plate with a brown paper gasket sealed with a proper gasket sealant which will not turn into "gorilla snot" and knack the engine. Link to comment Share on other sites More sharing options...
Dave McCulloch Posted November 22, 2006 Author Share Posted November 22, 2006 Is Loctite 598 an anaerobic sealant? I've read on here before that the blue plate and the bellhousing surface aren't always absolutely flat with the result that an anaerobic sealant won't seal properly - which is why I used silicone sealant last time around (only a small amount) - and there was no sign of any excess having tried to break away inside the bellhousing.

Paul Deslandes Posted November 22, 2006 Share Posted November 22, 2006 http://tds.loctite.com/tds5/docs/598-EN.PDF for the data sheet. Its an aerobic compound according to the data. BODS suggest using a paper gasket as well but this stuff works pretty well. Link to comment Share on other sites More sharing options...
Robster Posted November 23, 2006 Share Posted November 23, 2006 Wellseal is great stuff, smells good too! It looks like golden syrup and sets to a thicker version, but won't break off or break up. I used it on the MG because silocone does break up..liked it so much that I will use it for the Caterham when I need to seal things up. Link to comment Share on other sites More sharing options...
Peter T Posted November 23, 2006 Share Posted November 23, 2006 Wellseal Like using thick tracle. 😬 As Rob says it does not congeal into balls so therefore causes less damage if it gets into the oil supply after the filter.
