Re: 04 Navigator - 6-7-8 misfire, need good mechanic in Philly Area or Help
ok... my bad for not coming back and telling what happened.... but here goes....
On April 4th (sat. morning) i decided just to do... I pulled out the tools, popped the hood and went at it... i started on Cylinders 1-4 disconnected some hoses, moved some out of the way. basically took off anything that was directly in my way. Took the old plugs and coils out... popped the new ones in... im only 25-30 mins in and im already to start 5-8.... So i do the same on the other side as i did on the first... move everything out of the way yadda, yadda, yadda.... removed the cam that coves the coils and plugs and what do i see.... WATER!!!! 5-8 where filled with WATER!!!! i wish i would have took a picture but i was sooooooooo pisses and panicked that i wasnâ€™t thinking about pics... i was thinking about how much the dealer was going to charge me to fix this problem.... Well after i gathered myself i removed to boots and coils, got the shop vac and sucked all the extra rest and crap out of each hole. I then squirted a little WD40 in each because all i could imagine is each plug being rusted in there. So i let the WD40 set up for about 20 mins. Went in and slowly turned each plug about 1 full turn and let them soak some more.... Took them all out and gave it a final cleaning... It was looking good as new... so by now im still not calmed down but im focused on getting the job done i replaced each plug and coil. Then i looked and saw that the gasket has a huge tare in it and thats probably where the water came in at so just to be sure i put some gaskett seal over the replacement gasket (i know overkill but at the time it gave me a little sense of security).... So i locked everything back up.... reconnected all that a took loose and sat in the truck for the test start... With my heart in my throat and my hands literally shaking i turned the key.... She started right up!!! I was so happy.... i let her run for a few while io cleaned up... Then took her out for the test drive.... PERFECT!!!!! I ran up and down I-95 for about 150 miles that day... Took it up to 90mph a few times the to 100 a few... (kids dont try this at home, i come from a family of police and im a Mason so the chances of me getting a ticket are slim)... Once i looked up and the speedometer said 115... so i was satisfied that everything was ok.... BUT EVERYDAY i was a little affraid that something would go wrong but SO FAR SO GOOD. Shes running like a top... This weekend im going to take a look in at 5-8 just to make sure everything is ok...
NOW im looking to do some modifications... ANY SUGGESTIONS?!?!?!?!?!!?!
