Hey just wondering if anyone has ever replaced a spark plug tube seal and if its a difficult diy job? I found a decent amount of oil when changing my plugs in one of holes....Any tips or advice? TiA!

 

last night i got bored and decided to tear the car down to the valve cover... if its on the back side it is a little trickier than the front..


took me about an hour and a half to rip it all down.. I am a pretty slow mechanic too so normal people should only take 45 minutes or so.

 

the one that needs replacement is the left rear one.... has anyone ever replaced the tube seals i want to know how much work is involved and if i can possibly do this myself or is my only option to bring it to the stealership....??? Tia

 

I would just use some anti-seize and torque the plugs down to light spec (14lbs?). The washer on the plug should create a descent seal to the block.

 

The plugs create a decent enough seal, though it is still unnerving to have that oil leak.

I had two of them slightly leaking last November, so I replaced all six and both valve cover gaskets (also prone to leaking). Last week I pulled my plugs to check them, and one cylinder was completely flooded with oil. After pumping the oil out, and hooking everything back up, the cylinder still fires. I got the parts, and now I'm just waiting for an afternoon with some free time.

As for the job, the Haynes manual has a good guide, and it takes about 2 hours for front, and 3 hours for rear, from start to finish. I made the mistake of taking out my spark plugs without plugging the holes, and I accidentily dropped a piece of paper towel down one of the tubes, so I had to take off the lower plenum as well, so mine ended up being a two day job. On the plus side though, the lower and upper plenums were both COVERED in gunk, so it was nice to clean them out.

Just give yourself plenty of time, and plug holes that you open up, or just leave your spark plugs in the whole time.
