I recently re-built the engine and replaced the exhaust manifold (cracked) with a Pacesetter header. The exhaust gets extremely hot and the header glows red. I found a leaking fuel line back by the tank and replaced it (thinking that a decrease in fuel pressure/volume was causing the engine to run lean). The fuel line repair did not change the exhaust overheating condition. I plan on borrowing a friends fuel pressure tester and check the fuel pressure. If the fuel pressure checks out ok, how do I go about making the fuel injected engine run less lean? way2old Veteran / Moderator Dec 7, 2008, 12:53 PM Post #2 of 4 (3142 views) Re: Nissan Exhaust overheating Sign In Is the coil output enough to burn all the fuel? If not, the unburned fuel may be re-igniting in the header due to the heat causing the header to glow. Being way2old is why I need help from younger minds Loren Champlain Sr Veteran / Moderator Dec 7, 2008, 4:50 PM Post #3 of 4 (3139 views) Re: Nissan Exhaust overheating Sign In Just a thought; Did the headers come with a port for the O2 sensor? Loren SW Washington doctormac New User Dec 8, 2008, 8:22 AM Post #4 of 4 (3134 views) Re: Nissan Exhaust overheating Sign In The header did come with a port for the O2 sensor and EGR tube. A new O2 sensor was installed and the EGR tube was re-connected after the re-build.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
