i tuned up my v10 this weekend and all plugs came out just fine. the problem was the #4 plug would not go back in. i ran a tap down through the hole and it went very easy. tried to install plug again and no go!! i even swapt plug from #1 cyl and it wouldnt go either. any help or suggestions thanks!!

 

Uh Oh!!!! You Ran A Tap In The Head? What About The Shavings? Were There Any? Did You Do It When The Engine Was Completely Cold I Hope? Anyway, A Hole Is A Hole... If You Ran A Tap And You Tried Another Plug In It And It Still Will Not Go In, I Never Heard Of That One, Sorry, Keep Us Posted Thanks.

 

uuhhhhhhhhh? what kind of tap??? i hope it was not a normal thread or pipe tap. it needs to be a spark plug tap like a timesert tap.

 

Hey Ford, This One Looks Like It Is Gonna Get Ugly, And Maybe Expensive Too.... Hopefully He Did Use A Spark Plug Tap And Put Some Grease On The Tap To Catch Any Metal.

 

No response is a bad response.

 

i used a 14mm x 1.25 t urned it in with my hands. and i had it greased. it seems like plug is maybe not seating right to get started.

 

i have even switched plugs from other cyl and even tried a new one. this is really weird. any idea how much these timesert kits run and due you have to remove cyl head?

 

Did you get a light and shine it down there to see if there's any obstructions?

 

yes i had the use of a bore scope and the seems to be some corrosion maybe where the plug metal and the alluminum had corroded. but i looked at the #1 cyl and it looked about the same. but the plugs goes just fine in that one.

 

hmmmm. Never had that problem before, just had the problem of the plug wells filling with water.

 

well i just determined that the spark plug was blown out of my cyl head and there are no threads left. i have to rethread the hole use a insert. i will post how everything works out probably wont get to it till sat morn.

 

good luck, usually you can not rethread the cyl head if it blows it out, it may work for a little while but will blow out again ... only real fix is to replace the cyl head. gotta love the aluminum heads on the v10s and v8s

 

if you ran the wrong tap in the cylinder, they sell taps and hellie coils(i can spell) at pepboy and autozone. basicly you tap out the hole bigger and put in the coil so that it returns to the right size.

If the engine is cold you should not have to worry about the cylinder. The first time you fire it up, all the little pieces fly out the exhaust port. Its usually a mechanics trying for more money on a rebuild.

I was under the same impression, when I had to tap a cross threaded plug in a vw corrado. I bought a rebuild kit, only to tear down the engine to find nothing wrong.

Good luck
