In Florida this past weekend there seemed to be quite a few Glow Plug failures in flight, at least that was the buzz around the pits. It also helped me in a heat

I've had a stash of plugs that I have been using for a couple years, and its tough to wear them out if you don't go to lean, but the rumors were that the newer plugs were failing.

Anyone have any dirt on this???

I need some plugs for the season, but will stick with my used plugs if this is the case.

You should sell the rest of that bag of plugs to me for .50 cents a plug. Then buy all new ones..LOL..

Not sure what Cady had going on. Helsel said his blew out the seal. I don't know if that meant the seal around the stem? or the seal between the head and plug? Sound like more guys should be using the SuperT trick... Take ATF (oil) and put some drops on the head after you tighten the glow plug. Slowly turn the motor to top dead center, and check for bubbles in the oil.... they are not hard to see, can't miss em...

I can't say I've heard anything. I bought a dozen before Winterfest, and haven't had any issues with the ones I've used. This past weekend at the basin, I was still using the same plugs that were in my engines at Winterfest and the Phoenix gold cup in both my Q500 and Q40.

Dave/Gary,

Just out of curiousity which plugs were you using?

These are Nelson Heavy Duty Plugs

I've been using the same ones as Dave, Nelson HD.

Anyone have any good tips for a plug for the TT40?

I use OS #8 with good experience but don't know if it'll extract optimal performance from the motor and at almost 9 buck a pop I'd surely like to have a less expensive alternative.

Reno,

For that engine, there are cheaper alternatives.

Locally, we use the KB 1L, KB HP, or McCoy #9 all successfully with the OS .46 AX.


I wouldn't personally spend the extra dough on the #8 os plug.

I like the KB 1L, KB HP, McCoy #9 and Enya #3. But overall my primary is the OS #8 even though I pay 5 bucks apiece for them (on discount mail order). Too often they have fixed problems that seemingly have nothing to do or should have nothing to do with glow plugs. That's enough for me. I simple don't tear things apart until I've first tried an OS #8.
