Need Help replacing the spark plug tubes! How much effort should be used in the removal and replacement? Are there seals at the bottom

Do you mean the seals on the valve cover for the spark plug holes??

They can be a PAIN in the if you dont have the special tool that presses them on.

No I mean the actual tubes, evedently they twist in and out. Not sure if there is a seal at the bottom or not. I have already replaced the valve cover seals and they are ok. The tubes are leaking at the very bottom.

The valve cover has 4 seals at the spark plug holes. THEY are no "tubes".

You need to drive the seals OUT & then press new seals into the valve cover...MB part number 111-016-07-21 (4 required).

Thanks M>B> you truly are an expert at your field and in your advise. I punched a hole in the #4 seal and that's where my oil was coming from. I got some very bad advise fron some locals that told me there were removeable tubes. Thanks for your help and may God Bless you in all your future days!

To Him be the glory! We only enjoy our success because of His love. By the way I did not use the recommended special tool I used a pipe to exact size. But, thank you for your expertise and causing me to look more closely.
