Yes, that is certainly true. Cats don't die , they are killed by poorly running engines. Sounds like he's just blowing you off because he can't figure out the problem. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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. warbeast Novice May 15, 2014, 3:37 AM Post #3 of 4 (2226 views) Re: new cat and bad gasket Sign In hi thanks they did find it had a leak and replaced the seal and sparks so it has no problems now but leak was fixed a month after they replaced the cat so i was just concerned that running it for a month with the leak could have damaged the new cat thou the car run fine for that month with no exhaust problems that i could see only the slight miss when idle the oil level didnt drop again thou the sparks were already flooded by this point (This post was edited by warbeast on May 15, 2014, 3:42 AM) Hammer Time Ultimate Carjunky / Moderator May 15, 2014, 3:43 AM Post #4 of 4 (2217 views) Re: new cat and bad gasket Sign In You're probably OK. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 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
