Robert Posted October 28, 2005 Share Posted October 28, 2005 ok, ive tried my hardest to find a smaller expansion tank but i cant, ive tried all my local scrap yards etc. Currently my stock expansion tank is located where the stock air box used to be as i have HKS FMIC fitted, now i want to refit the stock UK air box i need to move the expansion tank or find a new smaller one. Could i use an oil catch tank as my expansion tank? Quote Link to comment Share on other sites More sharing options...

Miguel Posted October 28, 2005 Share Posted October 28, 2005 Depends on the catch tank . Idealy it would need to have an internal pipe that sits close to the bottom of the tank. Ie the stock expansion tank is not just for over flow when the engine gets warm ...the system will draw back into the rad from the expansion tank also...hence the level rises and falls...if the oil catch tank you are going to use has not got a pipe that goes from the top to the base then no.

terribleturner Posted October 28, 2005 Share Posted October 28, 2005 Rob did you not get one with your IC?? Not sure about using the catch can, but you could always use an empty coke bottle. Quote Link to comment Share on other sites More sharing options...

b_have Posted October 29, 2005 Share Posted October 29, 2005 Robert, the fmic was already fitted when I bought it, I use a mazda expansion tank on mine. There must be hundereds of little ones at any scrap yard. Quote Link to comment Share on other sites More sharing options...
