spark plug tube seal fitment. spark plug antiseize (6 Viewers)

Doing the valve cover gaskets, etc this weekend and have a couple questions. I ALWAYS use OEM, but when I bought my 100-series two years ago, the PO passed along a fel-pro gasket set which includes spark plug tube seals. Worked on the passenger side today and the new spark plug tube seals went in with no issues - too easy in fact. Everything i've seen\read, and my experience with these kind of seals on 2-stroke engines is that they need to be hammered to seat properly. The fel-pro went in by just pressing very firmly with my fingers. Has anyone else used these seals and can comment on their longevity or ability to seal properly?

Second question is spark plugs. When then were last changed, someone used anti-seize. I know the consensus is to install them dry, but i'm wondering if I need to try and get any of the old anti-seize out of the threads. I've already installed and torqued down new plugs (Denso IK20TT).

I have a feeling you will be replacing that Fail-Pro kit in short order.

The tube seals have tabs that get pried up to remove the old. The new fit in and you hammer the tabs back down.

Cleaning the spark plug threads is probably wise. But since you are that far along… what did you torque the plugs to?

Replacing the valve cover gasket as well or just the tube seals?

Tube seals are in although I have not hammered the tabs back down.

New plugs are torqued to 17ft-lbs

I just would not use anything Fel-Pro. Tube seals or VC gaskets. The likelihood of repeating the job soon is high.

Dont forget FIPG on your half moons, too.

Maybe more spark plug wizards will chime in about having residual AS on the threads. You have already crushed those washers on your new plugs…
