    Intermittent Flashing Service Engine Soon Light 02 Gt

    Flashing means a misfire is occurring. You may have one or more P030x (x=0..8) codes stored. P0300 is a random/multiple misfire code while P0301..P0308 point to specific cylinders. You might start by pulling the coils and checking down in the plug wells for oil (sometimes valve cover gaskets...

    Engine Oil Gauge Stays On Low! Car Making Noise, Please Help!!!!

    See if you can get a clip or get an opinion from a local shop. You don't want to have to spend more than you have to. I'll mention that a hurt rod bearing (a "spun bearing", where the bearing shells grab the journal and start to turn within the rod big-end) can spread metal shards throughout...

    Engine Oil Gauge Stays On Low! Car Making Noise, Please Help!!!!

    Can you post a video of the sound? If the engine was running without oil pressure for any length of time, especially under load, I'd be more worried about rod bearings than the timing chains. Journal bearings (like the rods and mains) require pressurized oil to survive whereas the timing chain...

    Engine 2002 Gt With 91,000 Miles (oil Looks Like Metallic Paint)

    Pistons are made of an aluminum alloy with a silicon component (that's what makes them hypereutectic.) Wear of a piston skirt might lead to those findings. If the engine's not making any noise nor consuming gobs of oil I'd just keep an eye on it. Run some decent oil, change it and the filter...

    Possible Egr Or Coil Pack Issue?

    With the info given neither of those would be my first suspicion. Your car has 8 individual coil packs; even if one went bad it wouldn't prevent the car from at least starting. An EGR valve that's stuck open can cause rough idling or even stalling but it won't stop the thing from starting...

    Is My Engine Done?

    With the spark plugs removed and the trans is neutral, can you turn the engine using a socket and breaker bar on the front crank pulley bolt (turn it clockwise as seen from the front of the engine...)?

    Fuel Pumps Won't Stop Priming

    You mention a BAP; do you have a damper disc installed in the FRPS? If not, the FRPS may have been damaged and the PCM is not getting real fuel rail pressure readings from it.

    Is My Engine Done?

    How deep was this puddle and what do you have for an intake? If you had to remove the plugs to get the engine to turn over it sounds like the engine ingested liquid water and "hydraulic-ed"; water is not compressible and when one or more cylinders came up on compression, the engine was...

    2004 Gt Cams?

    Do you know what specific Comp part numbers are involved here? "Stage 4" isn't in their catalog :/ You'll want to make sure the cams are for PI headed engines. For an aggressive cam you might want to check for PTV before spinning the engine with these cams installed. You're going to want a...

    What's This Thing Leaking Water?

    Not sure if that fitting itself is replaceable. Perhaps a replacement manifold is in the cards. Does it look like this: http://www.jegs.com/i/Dorman-Products/326/615-188/10002/-1

    What's This Thing Leaking Water?

    Looks like the heater core supply on the manifold. There's some talk of it leaking on the 5.4 in F150s. For example: http://www.f150online.com/forums/v8-engines/423144-97-5-4l-coolant-leak-rear-intake-fitting.html Also, the leaked stuff looks very rust-coloured. Once repaired you're going to...

    Help With Transmission Leak (mach1)

    (Sorry, 4 bolts...) Internally it looks normal. It's the top surface where the shifter mounts that you need to seal. Did you notice any fluid on the sides of the shifter box indicating a leak before you removed the shifter?

    Help With Transmission Leak (mach1)

    It's possible the leak is coming from the shifter box. If you pull the shift knob, the interior trim, the cover plate you'll see ~6 bolts holding the shifter to the top of the trans. If the shifter's been off the car or it has an aftermarket piece it may be leaking there. If so, pull off the...

    Is This Worth It? 5.4 Gt With Mach 1 Trans

    TBH, I wouldn't. I have a 2010 STi and actually prefer it to the Mustang (sorry...) You say the Rex is immaculate: If it was a beater POS I'd say go for it but unless you hate your blobeye for some reason, I don't see the car you're talking about being an even swap for the WRX.

    Is This Worth It? 5.4 Gt With Mach 1 Trans

    Don't really think the "Mach 1" transmission is anything special; it's the same TR3650 used in the 02-04 GTs. 47-lb injectors on a normally aspirated 2V?? The price doesn't seem unreasonable but there's no reason to not make a lower offer on it.

    2002 Mustang Gt Misfire Help Please

    Check for an oil leak from the valve cover gasket in the vicinity of the cylinders reporting issues. Oil can get down into the plug recesses and cause issues with the ignition. Crown Vic but same idea: View: https://www.youtube.com/watch?v=RD4lgno-_as

    96 Gt And It Is Misfiring On Cylinders

    Any work done on the car recently that involved, say, removing the engine or cylinder heads? If so, any chance a wiring harness was pinched during the process?
