Stuttering, NEW HINT. wisemen?

[swarm]

Ok, so I have had a stuttering problem for about 9 months. I bought the car with this problem. It was stock when I started diagnosing/replacing, and I added all mods and had no real change.

Aaaanyhow. I think I have a hint.

I went to the track last night, and after boosting a lot and such, it was still stuttering.
On my way home, my car made a loud POP after I went WOT. I killed the engine immediately thinking timing belt. I popped the hood and noticed the spark plug wire on #1 was not on tightly. I put it back on and drove again... it still stuttered. I went WOT, it popped off again. Aaaanyhow. There is also OIL in the valve cover area, and i can't get the plug wire to stop popping off. I searched, and it seems most people who have spark plug wires pop off have not finished the thread by telling what the issue was. I need some advice here. I think I will get a new valve cover gasket, spark plug seals, and the halfmoon seal. Think this will fix my issue a bit? Could this be the culprit behind my car's stuttering?

Thanks all

A valve cover gasket from Advance Auto or similar will cost around $25-30 and include the VC gasket, spark plug wells, and half moon.

My car sputtered a bit when my spark plug wells filled with oil. I replaced the gasket and they were bone dry...cheap fix and its never a bad idea to replace the gasket.

There IS no "studdering".

ANOTHER HINT!

When I pulled plug wire #1 and started the car with it out, the car ran fine! but it was arcing at the #1 area on the coil. I thought this was interesting. I put the plug back in. car ran fine, no arcing..


Every time I run my car, when it starts stuttering, i assume the plug wire is popping out and it is arcing at #1 on the coil. it it not the wires at the coil. just replaced coil, too.

soo... what can I do? is the spark plug not sitting properly? any ideas on how to remedy this? i think i am getting closer to fixing my 9 month problem with this car.

Have you replaced the plugs and wires?

Plugs don't pop off under normal conditions. When you put the new plugs in, torque them to spec (generally seated then a 1/2 turn)

Make sure that you do what you can to make sure that compression is not getting by the spark plug threads. If it is, it's likely that your head will eventually spit that plug and take the threads with it.

If you're having issues with the valve cover gasket, it's likely that you have a bad PCV valve. It could be that crankcase pressure is making its way past your valve cover gasket, which is popping out the plug. This is accompanied by the fact that you have oil in the spark plug valley, which happens when crankcase pressure blows out the seal at the oil fill cap. Check/replace the PCV valve, and check/replace the seal at your oil cap.

Have you done a compression check lately? If the PCV valve is bad, this will cause the problems you're having. If the PCV valve is good, you probably have very low compression and a lot of blowby. Have you had any problem with your oil dipstick popping out?

When you replace the wires check the coil. If the tower has been arcing it may be carbon tracked and etched requiring replacement.

Sorry that I didn't reply earlier.

The problem was a missing rocker arm.. it had fallen off and was sitting in the top of the head

How the F did that happen!?
