Why is my piston hitting my glo plug unless i add extra copper washer?Run a medium heat range plug.... outta be just fine.....
"Hpi nitro star 21 bb" the purple 3.5 motor. And i till my glow plug out of my trx 3.3 traxxasGot a pic and what model plug you are using???
The Piston is literally smashing into the glow plug physically hitting it what would cause that? Are there different glow plugs with different depths?Why is my piston hitting my glo plug unless i add extra copper washer?
Yes. Short (4 thread), standard (5 thread) and long (6 thread) I think. Traxxas plugs are long. OS sells some long ones for their TM engines, LC3 and LC4, not sure why they did that. Seems silly to make a special long plug just for a couple engines they make. Perhaps they were trying to cater to the traxxas engine guys too. Probably a few others that are "long" plugs too.Are there different length glow plugs?

I just traded my traxxas slayer 4x4 short track for the the slightly older hpi savage 21 with the hpi nitro star 21 big block (3.5) the black and purple 1/8 scale monster truck. (With the purple engine head) Does that motor take a short glow plug? Because i put a few washers on the traxxas plug and got it to fire and run. But i didn't want to risk ruining the piston or sleeve so i shut it down without making Any pulls.Yes. Short (4 thread), standard (5 thread) and long (6 thread) I think. Traxxas plugs are long.

What plug do you have and what engine?
Short: Fox Short
Standard: OS #8, OS #6 (A3)
Long: OS LS3, OS LS4, Traxxas Super Duty
I use odonnel medium temp in my LRP's. Appears they are a bit longer than standard plugs. They tend to be cheaper than others and they run a good long while. I run OS LC3 in my 2.5 jato and LC4 in my 21TM revo.

I understand that it will take a short plug and medium heat range. But would a traxxas super duty cause clearence issues? I'm trying to make sure that is the problem i was having.Yes it will take a short plug and medium heat range....
Take the head off the engine, put a single washer on the glowplug and see if the plug goes into the head button beyond flush with the expansion dome:I understand that it will take a short plug and medium heat range.
