Bad sound from engine

[AaronLG]

Anybody tell me what might be the issue here. Noticed a bit of hesitation and ticking sound on the way home from work. Checked the oil once home and it was a bit low. Added some and tried to restart. Trucked made a pop and a puff of white smoke from the left side of the engine. I turned it off and waited a few. Now it makes the noises you can hear in the video. Any help guys?

Did you check to see if you blew a spark plug out. It sounds to me that you did. Pull all your plug boots one at a time, one of them is probably blown out.

Sounds like a piston to me. I would'nt run it long like that if at all. I'm new here so don't take my word for it though. I know these things can blow spark plugs out too but don't know what that sounds like. Last time I heard a sound that bad it was catastrophic failure time.

Well SkyJumper beat me to it. It's probly the spark plug like he says and disregard my ignorance.

Kind of hard to pull them with out taking everything apart. The coil packs all seem to be on tight and everything visually looks ok. Got to dark to mess with. Have a mechanic friend coming by tomorrow after work. Thanks for the help guys. Will let ya know how it turns out.

+1 what Skyjumper said!

The spark plug boots are not difficult to get to to inspect if a plug has blown out. Just reach down and pull on them one at a time. Sounds to me it is on the driverside and that is the easiest side to gain access. If one did blow out, the plug wire may indeed be shot out of its port and you should see that fairly easily. The sound should lead you right to the cylinder in question.

They all look ok but will try to get at them this weekend. From what i've read you have to do a bit of wrenching to get to them. Any other input would be appreciated if it is easier then what is posted.

Not to drag this out on you, but I just replaced all 8 plugs last month. It took all of 25-30 minutes with my fat fingers. The hardest area to gain access is the P/S rear 2 cylinders as you have the heater core hoses in the way and have to move them to the side to gain access. The D/S is the easiest and you have to remove nothing to do spark plugs, not even the intake tube.

So if one is blown out what do I have to do?

 

[SkyJumper]

You will have to repair it with a HeliCoil kit or TimeSerts, they are threaded inserts/sleeves that you use to replace what was once there. They are actually stronger than oem threads.

So what do you think it will cost to fix? Got one quote for $350.

Did I miss something here, has the problem been identified? I ask that as to how you got a estimate without knowing what the problem is. And someone looking at it first to give a proper estimate.

Spark plug blown out or bad exhaust leak is my guess but I'm guessing like everybody else it's gonna be the plug.

Spark Plug Blown Out

Just they way it happens when the plugs blow out. You hear the ticking and then they blow. If the coil packs are still bolted down then it will hold the plug in place. I had one blow out while towing my race car from Philadelphia to Palm Beach, Florida and had make the repair at the the track in Florida. I had the kit for doing the job at my shop and had my guys overnight it to me so I could do the repair. Ford did not put a complete set of threads in the spark plug holes for some reason so it is no wonder they blow out... I have a automotive repair and machine shop and I see these all the time. I would only have a Timesert put in. Helicoils are likely to come out when you change plugs.

Sounds like a blown out plug

The last one I had took out the the CP too.

I can see the coil pack bouncing up and down. It's on the passenger side, third one back.
