[QUOTE="Frisco69, post: 255380, member: 1160"] Take the valve cover off and turn the engine with a 30mm spanner (make sure it's out of gear). Watch the exhaust valve to make sure it closes fully. It could be stuck open slightly. Do a compression test if you can on all four cylinders. If number one is way down then there is a problem. Was it running ok when it was laid up? I think you mentioned it's been laid up for a while so the valve could be stuck open slightly or seats are corroded. If they are corroded cranking it over for a short while with fuel disconnected is sometimes enough for them to beat back in and reseal. Like wise cranking it over may free off a stuck exhaust valve. I hope I'm not giving you a bum steer and making more work for you but I think you need to look into it if you are certain there is no external leak. And if fuel is leaking out of the exchanger you must have a hole which means obviously exhaust gases will enter the cabin but first things first. [/QUOTE]
