  1. 2003 Mustang Exhaust Leak

    V6 Tech
    I'm getting that same exhaust tick that a lot of these 3.8 motors get. Already replaced both sides manifolds and the tick is still there. Any idea on what else it could be?
  2. 2001 GT engine noise

    4.6L Tech
    I know that describing a sound over the internet is very hard but I'll do my best to describe it. My 2001 mustang gt with 4.6 has what I would describe as a "ticking" or like a "clicking". Its almost has a pattern like tap tap tap, tap tap tap, tap tap tap in very quick succession. I can only...

  6. ABS Light. New O2s/Exhaust Leak=Off. Fix Exhaust Leak=On

    SVT Cobra Tech
    So I posted awhile back about my ABS light being on but not being able to pull codes. The other day I replaced my oxygen sensors with Motorcraft's OEM sensors due to a CEL (check engine light) that came on every so often. They fixed the CEL and actually got rid of the misfire feel I was having...
  7. 5.0 new intake manifold exhaust leak

    5.0L Tech
    I installed a new intake manifold on my 1990 5.0 and it sounded like a bad exhaust leak when I started it up. The only thing I can think of is when installing the intake the gasket between the manifold and the heads slipped out of place and the noise I am hearing is exhaust crossover leaking, is...
  8. new intake manifold problems

    Classic Tech
    I replaced my intake manifold on my 5.0 L, started the motor and hear what sounds like a bad exhaust leak.

    I have a 2000 GT with 155,xxx miles. I am getting a noise the majority of the time that sounds similar to an exhaust leak. I know what an exhaust leak sounds like because I owned a Mustang a few years back that had one. My current Mustang had the back half of the system replaced because the...
  10. 2002 Mustang 3.8 exhaust problem

    V6 Tech
    Hello.... I changed the clutch on my Mustang, and I can't seem to get the exhaust connections not to leak. I have a small leak from the muffler connection, but a large leak from the right bank. The left bank is just fine. Could this be a problem related to the a/c drain dropping water on the...
  11. Seafoam to find exhaust leak?

    Classic Tech
    I'm trying to find an exhaust leak and I've stumbled upon discussions about seafoam cleaning engines and producing lots of smoke. I figured I can kill 2 birds with one stone. Popular choice seems to be 1/3 fuel tank, 1/3 crankcase, and 1/3 can into intake. Is this safe to try in 66 with stock...
