Hi guys, quick couple of questions...what is the best way to clean the exhaust components and to take off old gaskets.

<br /><br />You can get a gasket scraper at any auto parts store<br /><br />You want to put a rag in a hole like this manifold so the stuff does not get in the motor <br /><br />The KEY word is to scrape NOT gouge it can take some time ,i like to finish it off with some Scotch Brite Pads <br /><br />You want to get it clean BUT not remove metal<br /><br />tommays

Take the manifold off and flush it with water the best you can. Saying that, I still have been able to hear rust rattling around in them after doing that.

best gasket scraper i ever owned and still use is the cheapest plastic handle 1" wood chisel.

I use the 3M pads on a drill. eats gaskets and does not damage metal. check the surface flatness of the gasket surfaces with a straight edge and feeler guage, the corners near the bolts tend to rise.
