Tapping/Knocking Noise

[bearq3114]

Heard a little noise yesterday on the drive home from work. Went inside for a while came back out to try and diagnose the noise restarted the engine couldnt hear a thing. So today i thought id grab a little mystery oil put a little in the tank a little in the oil. Drive around for another 30 minutes and I start to get this noise. Any guesses on what it could be?

I did change the oil a couple days ago to 10w-30 full synthetic but i don't feel like that is the problem.

hopefully others chime in, but my guess is: loose spark plugs, timing chains are starting to go, or exhaust leak (not likely)

[BigM460]

I'd check the plugs. Hopefully its just loose.

Update went out to start again sounded like it barely wanted to start before it finally did. Ill check the plugs now

Had a click and slight vibration. Changed belt tensioner assembly and belt. Problem solved. Can't explain the slow start. Checked your water level in your battery ? Good luck. Maury

after another inspection i felt vibrations/knock on the driver side vallve cover gonna open her up this weekend, now I'm starting to think maybe a lifter.

i would get a mirror on a stick and look at the bolts on the manifolds. That is where i would start.

A Ford dyno engineer once told me "don't worry about the tick" I say, just drive it till she blows

This would be a place I would look too.

Does the car have headers?

[bearq3114]

Nope everything factory

I don't want to be the bearer of bad news but it sounds a whole lot like the infamous head tick. My drivers side head became overheated due to a broken lower coolant hose while out in the swamps of Atchafalaya. It was hours before we could get to a service station and obtain repair kit. The tick manifested itself months later. Had to have two exhaust seats replaced. Zack was a huge help in getting my M M running again. Shoot him a PM, he can help I'm sure.
I did have a noticeable compression loss on those cylinders. IIRC.

Check compression and leak down would be my suggestion.

I'll guess blew a spark plug out

[camelgrundle]

if that's a head tick it's the loudest I have ever heard one. My guess is plug too.

[a_d_a_m]

I don't remember my head tick being that loud but I guess it could have been and would probably be where I started...

[bearq3114]

if you guessed blown spark plug you were right. I appreciate all the help took off the driver side valve cover to see a busted ignition coil and a destroyed spark plug. First i have to fix the threads on the head. Then Gonna take time to change all the plugs, since I feel as if the previous owner never had the plug seated in the head properly.:beer::beer:


Side note : I love how helpful the forum is gonna start becoming more active here as I finally have my marauder. Been saving and searching for 2+ years :banana:

If you have an 03 they have 4 thread heads and were probably over torqued hopefully thats the only one..

[bearq3114]

had to rethread it with a kit. Also, none of the other plugs were tight i screwed them out by hand. I toruqued the new ones to 11 ft lbs

[bearq3114]

Also got a question when I fixed the head. I measured the distance from the top of the plug to out the head. And it's about a quarter inch difference from the the thread I fixed to the originals. Does anyone think this would be a problem?

nevermind gonna just take it to a machine shop and get the treads rebuilt anyone know of a good one in the chicagoland area?
