unhuman Posted February 14, 2011 Share Posted February 14, 2011 Got some baked on gaskets on an intake manifold. Anyone got some suggestions on how to get them off without ruining the aluminum surface? Cheers. Quote Link to comment Share on other sites More sharing options...
KKtrips Posted February 14, 2011 Share Posted February 14, 2011 If you have the manifold off and out of the car - then the wire wheel on a bench grinder will do wonders for you. If it is still in the car and you can't be fucked pulling off the hoses etc then use a sharp blade to get rid of the majority of gasket then get a block of wood and a length of emery paper (or coarse sandpaper) using the wood as a sanding block sand all the remaining gasket off..

Unclejake Posted February 14, 2011 Share Posted February 14, 2011 Personally, I wouldn't use a power tool of any kind on the mating surface of an alloy manifold, unless it was a large linisher or surface grinder You can purchase cans of gasket stripper, which work well. Essentially they are paint stripper so if you have some paint stripper then perhaps try that and a scraper (not a sharp one). If you do damage the surface then you can lap it flat again using a sheet of glass as your working surface and full sheets of Wet'or'Dry sandpaper. Spray CRC onto the glass and both sides of the sandpaper and you will find the paper sticks to the glass. Place the bare manifold onto the abrasive side of the paper and carefully slide it around in an oval motion to lap the mating surface flat again.

efp0wa Posted February 14, 2011 Share Posted February 14, 2011 CRC gasket stripper, will bubble away and eat at the gasket. Then scrap off with scraper. Quote Link to comment Share on other sites More sharing options...
