Rough to start Light white smoke Blue/ black discharge from tail gentle backfiring, not loud. Oil is full, but maybe had slight blue color? Head gasket? Running rich? What do you guys think. Tom Greenleaf Ultimate Carjunky / Moderator Apr 7, 2018, 2:27 PM Post #2 of 3 (1590 views) Re: 2000 3.8 v6 mustang 84k many symptoms Sign In Ok, is coolant low at radiator? Things you can begin checking is oil dirt in tail pipe or if somehow antifreeze should rinse off the oil wouldn't with plain water on a towel. "Hard to start?" Next if you can/know how to, cancel spark one by one when first running see which one doesn't make it rougher mark that one. Then can look at plugs for differences - oil would show dirty, antifreeze if firing can show a very clean plug vs the others then on to compression check see if it holds. While plugs out see if pressure check of cooling system shows up at a cylinder just look can do that with engine cold even. I prefer to find more than one reason to blame head gasket(s) before taking that on be sure several tests more than mentions a couple about proves it or not conclusive. Good luck the "blue/black" still could be antifreeze if also seen cold mornings if cold overnight be tricky but it isn't running well so should find out what with a few checks. See what you find if one or more bad looking plugs swap to a good one see if problem follows. Pretty sure a code reading can tell you which cylinder(s) are making it run rough or if random helps, T Hammer Time Ultimate Carjunky / Moderator Apr 7, 2018, 3:49 PM Post #3 of 3 (1587 views) Re: 2000 3.8 v6 mustang 84k many symptoms Sign In Before you do anything, have the codes read and post the numbers here. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   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
