NigelH Posted February 1, 2010 Share Posted February 1, 2010 I've had this engine for a couple of years and it's now got burnt oil on the cylinder head and where the silencer attaches to the engine. Is there a low cost and quickish way to get this off without boiling it, soaking it or dismantling it ? Elbow grease is an option and if anyone wants me to send it to them so they can show us all how good they are at cleaning engines then let me know Thanks Quote Link to comment Share on other sites More sharing options...
Ad's Posted February 1, 2010 Share Posted February 1, 2010 hi nigel, you could try baby wipes, its amazing how they clean the grub off either that or fairy power spray. May only need a little tiny bit of elbow grease to wipe off after spraying on Quote Link to comment Share on other sites More sharing options...
Ed Darter Posted February 2, 2010 Share Posted February 2, 2010 I've not come across a way without either boiling or using power spray etc. Haven't tried it myself but don't think baby wipes will touch burnt on castor..... Quote Link to comment Share on other sites More sharing options...
Myron Beaumont Posted February 2, 2010 Share Posted February 2, 2010 Brass brush (for 'er indoors's swede boots) and petrol or Cillit bang .whatever it's called BUT don't leave it on too long (cillit bang that is) -It makes aluminium alloy engines whatever go very grey & matt coloured .Ask me how I know ! -I left it on over night on a castor burnt on cylinder head! No problem -in fact it probably cools better ! Quote Link to comment Share on other sites More sharing options...
Don9f Posted February 2, 2010 Share Posted February 2, 2010 Hi, I use Nitromors paint stripper.....but beware its not stuff to get on your skin or eyes ! Agitated with a small brass wire brush, it will dissolve burnt on oil. Cheers Don Quote Link to comment Share on other sites More sharing options...

Hamish Posted February 2, 2010 Share Posted February 2, 2010 Fairy Power Spray and a tooth brush. No problem Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted February 3, 2010 Share Posted February 3, 2010 Hello Nigel Bettaware oven cleaner or they may call it carbon remover will remove all traces of burnt castor given time . If your engine has a painted finish ,ei; blue LA or a red irvine it will strip it back to aluminium . If its already alumininum its the best stuf to use as it wont discolour the aluminium like Mr Muscle and some other products . you could also try a immersing the engine in Cellulose thinners and give it a brush with an old tooth brush or similar .Thats the downside of using castor oil based fuel . Use a good sythetic and your engine will wipe clean for years without need for brushes and chemicals . I wouldn't recomend using synthetic oil fuel in this engine especially if the piston is discoloured or laquered as the synthetic will clean away the laquer and the engine could loose its compression . Whoops ! Have I started a Castor versus Synthetic debate again ? Quote Link to comment Share on other sites More sharing options...

NigelH Posted February 7, 2010 Author Share Posted February 7, 2010 Thanks gents. I'll give it a go and report back on how I get on. Fairy Power Spray looks popular and should be easy to find. Once I can get hold of the wife's toothbrush I'll give it a go Quote Link to comment Share on other sites More sharing options...
Myron Beaumont Posted February 8, 2010 Share Posted February 8, 2010 Nigel Once you've "acquired" the wifes toothbrush & used it ,wash it well otherwise contaminants might dissolve her dentures overnight when soaking Quote Link to comment Share on other sites More sharing options...
winchweight Posted February 8, 2010 Share Posted February 8, 2010 Power spray is the least offensive cleaner and is very effective. If your engine is the blue anodised one, then nitromors or any other thinners will probably strip this off as it is actually painted not anodised. If it is a bare metal finish, then these will also cause the metal to discoulour if left on for too long. As an aside, I found an old engine (Merco 60 WD) on Salisbury Plain, which had been shot down on a gunnery target for AA gunners. It was thicj with mud and corrosion. I stripped it, soaked it in cellulose thinners, washed it and then replaced the bearing and oiled it. It ran just great until I sold it.
