a98pmalcolm Posted January 11, 2016 Share Posted January 11, 2016 (edited) Hey all. I under stand the Supra doesn't have a replaceable pollen filter so I'm ruling that out. Since I have done my plenum inlet manifold and located the inlet cam breather hose into a catch tank (as well as my exhaust cam breather from a single turbo conversion) I have had a really strong petrol smell and I believe its coming from that. The oil catch is located at the back rear of the turbo. But its only when the heater blower is on I get the strong fume smell, so I'm interested to see were the air is sucked from for the fuel smell to get in. Also when there on my car steams up terribly and I get a clammy kinda feel so there could be moister in the system. An advice would be great Thanks Paul Edit: Solution below Edited January 19, 2016 by a98pmalcolm (see edit history) Quote Link to comment Share on other sites More sharing options...
David P Posted January 11, 2016 Share Posted January 11, 2016 Have you dicked about with the charcoal filter too? Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted January 11, 2016 Author Share Posted January 11, 2016 Have you $#@!ed about with the charcoal filter too? The tank has been removed for a little while. The fuel breather has been reloted to the line in the wheel arch. No fuel smell when i did that.. Quote Link to comment Share on other sites More sharing options...
David P Posted January 11, 2016 Share Posted January 11, 2016 It's either that, over-fuelling or a fuel leak. Blank off the fuel breather line and see if that sorts it. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted January 11, 2016 Author Share Posted January 11, 2016 (edited) ok will blank it off and check. Cant find any leaks and the afr is spot on.. Thanks Edited January 11, 2016 by a98pmalcolm (see edit history) Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted January 18, 2016 Author Share Posted January 18, 2016 Blocking the pipe didn't help sadly. When the blower is on hot i still get the petrol smell. only area i the engine that smells fuel is the air filter from the oil catch tank. will run a pipe to thr bottom of thr car were the catch tank filter goes. And will report back Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted January 19, 2016 Author Share Posted January 19, 2016 The smell was coming from the oil catch can filter as the breather pips from the excuse and inlet cams go into the tank causing excessing oil vapours going into 1 tank. I found this out by taking the filter off and using some hose I had spare extending the filter further down past the bulk head. Fuel smell now gone. So now I need to find a more permanent solution to this rather than a load of silicone pipes I used. Quote Link to comment Share on other sites More sharing options...
