my buddys 94 ATX SHO started acting really f*cing strange today. he got done washing the motor and we get ready to go out tonight and it feels like his car is running on 5 cylinders. so i pop the hood and i pull a spark plug and this Brown milkshake supstance comes foaming out at me. it leaking out form the sparkplug holes on both sides of the motor. i told him that i thought it was a blown headgasket. iv never seen a car do that and i dont know all thare is to know about the motor of the SHO. if somone can tell me or if this has happend let me know. thanks
SHO motor probelm. really weard thing happening

Did you guys wash it while it was still hot? Please don't say you pressure washed it.
no but he did wash it today like this morning with a weak *** garden house. and the motor wasnt hot case the did it after it sat for about 2 hours.. i already told him about being carefull about washing the motor. i shorted a spark plug once doing that. but why would thare be Choclatemilk substance gushing out of the sparkplug holes.

...because he has bad plug well seals, meaning the oil was already in there. Then he added water to the mix, and heat from the motor, hence 'milkshake'. He needs to replace his plug well seals. DO NOT LET THE 'MILKSHAKE' DRAIN BACK INTO THE MOTOR!. Clean it all out before you remove the spark plug! This would be a good time for new plugs and wires, since he probably has not done them any good and probably are all oil fouled.

OK ill try that. thats does sound about right now is it hard to change the plugs on the SHOs. iv never had to do it. does the mainafold have to be removed and are thare a lot of tools needed.(just asking cuse i dont know how to work on one of those motors. and he doesnt have the money to take to the shop) i couldn reach the back plugs hence also why im asking. if i knew what tools and stuff i could fiqure it out. now why would it fell like its running on 5 Cylinder i mean the power was really cut in half and iv never heard of something like this happening

And you are...Who???
The sparkplug or plug wire on a cylinder probably has has a crack in it.Electric allways finds the shortest path to ground.If water surrounds plug it acts as a conductor which would be easier for spark to ground out to the cylinder head inside plug well before it would travel through plug, to electrode,then to ground.Spraying water on plug wires is a common way for diagnosing bad wires.

You can change the plugs and wires with the manifold on..I have been told. I have never wanted to do the job that haphazardly, you can pull the manifold in 15min. Plus if you are changing VC gaskets, they you need to pull the manifold anyway. VC gaskets are ~$70 at AZ, you can get the AC Delco wires at MidwestSHO for I think ~$50 and plugs another $10-15 (motorcraft only). To get everything apart you just need a good set of sockets, and some opend ends to get the manifold brackets, along with a metric socket for the VC bolts (don't over torque those!...they will break!). If you want to fix it properly that is what you need to do.

Do the throttle body bypass so the intake will go back on easier and next time you'll be able to take it off in only a few minutes.

Ah yes....for some reason I forget about that since I did the bypass a while ago.

Please explain what it is, since this is new to me. The bypass that is.SHOtimer said:

DO NOT do the bypass if you live in an area that sees sub-freezing temps often. It can (and in my case, did) cause the throttle body plate to freeze open (picture driving up to an intersection with the throttle stuck open at 3/4...)

Coolant runs through the throttle body and IAB housing to keep them warm in winter months so that they don't freeze. But, during other times of the year it does nothing but heat up the intake manifold. What you simply do is reroute one small coolant hose so that it doesn't flow through the intake. This keeps the intake cooler and allows for much easier removal of the intake. For us Cali people we don't get cold enough for this bypass to hinder us in any way. But, if you do live an in area that gets extremely cold as Fred stated above ^ this would be more problematic that beneficial.

Any good write up you know of on "how to" or should it be self evident upon looking? It's raining here so I don't feel like poking around under the hood, seeing as how I have no garage. Also, I live in Delaware which rarly sees those temps so I don't think it would be a problem, besides when it's that cold I usually drive my Bronco in case it snows.SHOtimer said:

Ive honestly never had a problem with it freezing up, ever (even in -30*F weather). And we have some of the coldest winters in the nation up here.Yamaha V6 said:
EDIT: For an automatic I would have to agree with you. If by some chance it does freeze up you will be stuck in gear with the throttle down and that could easily cause an accident before you have time to react. You can just push the clutch pedal in with an MTX.
well its all fixed we when up to FORD and got the Plugs and Wires not cheap let me tell you and we got all that black liqued out of it and replaced the plugs and wires wich needed to be done really bad. so now it runs great and stronger than ever. thank you for all of your info and help.

You could have gotten the plugs and wires a lot cheaper at FPN. Also, if you didn't replace the plug well seals ( which are leaking the oil into the plug wells) then these new plugs and wires will get fouled out also. I would recommend doing that quickly so that you don't ruin the new plugs and wires you just spent a load of $ on. The seal set is only about $70, which is minimal insurance to what I expect you paid for those products at a dealer.
