[scratch] Hello and sorry to bug everyone again.

Yesterday I changed the sparkplugs on my car and the air filter and the PCV valve.

When I took off the sparkplug wires the plugs on the top end of the plug was full of this brown muddy stuff. Is that normal?

Now the other end of the plug that screws into the motor was fine no oil and the normal tan color it should be.

Also I just cleaned the tip of the plug wires should I have changed the wires also?

I did notice that my car use to idle very smoothly and now I feel it kida shakes a little and the RMP hang around 800 or sometimes it moves down just a little.

Please give me your input on this one.

Thanks

John

I'd check your wires. When you say muddy does that mean its liquid or is it crusty?

 

[p90xsexyguy]

Its crusty not liquid at all.. I am sorry to put this example but its kinda like ear wax.. It has a grainy texture to it. i wished I should of taken a picture. Let me see if I can find a pic online.

 

[fstrthnu14]

It sounds like your just getting corrosion. simalar to what adds up on your battery terminals. I'd recommend some new wires.

Perfect Example.

Ok guys here is a perfect example of what I am talking about. IN the picture if you look at the top of the sparkplug wire the brownish dust or I am not sure what it was, That was all over the top tip of my sprakplugs and also all on the outside of the Boot. I looked inside the sparkplug boot and it was nice and clean I just cleaned them with a rag and placed them back.

 

[p90xsexyguy]

if its corrosin how did it get there in the first place?

 

[CHillRyde]

Thats normal on the top of the plug connector. Its dust and dirt from inside the engine compartment baked into the rubber. On the plugs though? Theres no oil down there from a leaking valve cover gasket?

 

[p90xsexyguy]

I will post some pictures tonight to show you what I am talking about. When I look thur

the holes where I can see the sparkplugs its clean like really clean no oil or nothing. i am

thinking is still dirt and stuff from the engine. I will post the pics later on today.

Spark Plug and Wire pics

Here is the pictures of how it looks inside where the spark plug sits it like Algea or something like that,

The plugs also have the same brown dust on the outside and on the inside of the boot.

You've had some water in there at some time in the past. Probably when the motor was washed with a pressure washer. When the engine is started it gets hot and boils away. No big problem. Don't use a pressure washer to clean your engine.

 

[p90xsexyguy]

You are correct HyBalz I did washed my car recently about 3 weeks ago at my local

carwash with high preassure gun.

So are you saying I do not need to change the spark plug wires??

Or should I go ahead and do so?

I have change the sparkplugs and I did found that same brown stuff oh the top side of

the sparkplugs so I change them.

I clean the boots really good and everthing looks clean.

Let me know what you think.

thanks

John

If you still have the shaking you mentioned in your first post you should probably go ahead and change them. Did the shaking begin after you washed the engine or after you changed the plugs? If the shaking started after you changed the plugs, you may have a bad plug or or one with an inncorrect gap. If it were me I'd pull the plugs back out and recheck the gap and put on new wires. But that's just me.

What is the correct gapping for these sparkplugs? I bought the motorcraft Platinum.. I was told they where pre gapped and not to mess with them. This is Autozone people telling me this. I was also told by Oreily that the correct gapping is .054.. Also what wires hould I buy The Bosch cost me $30.00 and the Motorcraft cost me $50.00 they are both life time warranty.

Let me know

thanks

I usually just put a little dielectric grease in the boot and it will keep a lot of crap off the plugs. Try that it may work for you.

 

[HyBalz]

I think all plugs are pre-gapped but if one, or or a whole box, gets dropped it could close the gap a bit. I always check the gap before installing them. Last ones I installed I gapped them to .055" and I get no misfiring at idle or all the way to 7000 rpm. I like Motorcraft replacement parts but Bosch is a good namebrand, too. It's up to you.

 

[p90xsexyguy]

Well the shake it started when I changed the plugs.. I did pull the plugs and one of the

plugs was sold to me by error. I had 3 motorcraft platinium and 1 regular. (Autozone's

error") I returned it back and placed it in. The car still kinds shakes a little. It boggs

down when I acelerate sometimes feel like someone is pulling me back and the car trying

to fight again the wind or something. I am going to change the fuel filter next since I

have already bought it.

Avoid Bosch for spark plugs. Pretty much the general consensus of almost everyone on here. Motorocraft platinums are a good replacement choice. As for plug wires, I've never used Bosch personally so I have no real reference there. When I replaced mine, I upgraded to Taylor Thundervolt 8.2mm wires. I got them shipped from Summit Racing for around 60 bux. The Taylors are an insanely popular option with the site members here. With Taylors, you can get a gap up to around .060, giving you a larger spark for better burn.

Thanks for the Advise HawkeyeFLA, but I am trying to keep my car as stock as possible no modifications. I will go ahead and get the regular Motorcraft plugs.

Thanks

Do not run Bosch, I can not stress this enough. I don't care what any TV or magazine ad tells you, they are junk. I have personally broken the ground strap of 3 in a running engine with in 1 month from them being new, others have had the same issue, many others.

My recommendation is the cheaper AutoZone plug wires (lower resistance than the spendier wires, odd as it sounds (what I am running right now)) and stock Motorcraft or Autolite spark plugs (same thing really).


What the biggest problem is with spark plugs is there is no real benchmark to judge from. There is no set heat range that all brands conform to and much of the time a parts stores computer will just list plugs that are a similar reach and thread pitch, no similarity in heat range what so ever, basically it fits and that's it. So the Bosh Platinum plugs like I had where a higher heat range than was called for and detonation occurred which heated the ground strap beyond it's limit and it failed.
But the opposite can also happen if you go too cold, the plug just can't retain enough heat to opperate well at low engine speeds and you consistently run rich and sputter/misfire.
Stock is recommended for just those reasons, it's what the engine was designed upon and tuned with, hence why it works best.


*edit*

I just read your issue with the Ignition Coil Pack Pigtail.
That would have had a large affect on your performance and longevity of plugs/wires.

Sounds like everything is well now?

 

[p90xsexyguy]

My car works excellent iminhell.. I order the PCV hose Crankcase to change it I noticed that when my car turns on the hose gets sucked in like someone is pinching it. So far the car runs great, but I am swapping it just to make sure it will not bother me later on...


Thanks
