    Going through Glow Plugs like crazy!

    I'm going through glow plugs (traxxas long - medium) like crazy. Literally, it takes about a half tank of fuel and the plug is fouled - fused inside, broken, dirty, etc. I thought it was temperature related, and took meaures to change fuels - still 20% - just an alternate brand known by the LHS to keep engines running cooler. I cut vents in the body, I ran as rich as possible, and still - going through glow plugs like crazy.

    Then I noticed some debris of some kind on the fouled glow plug wire - like a dark gray glob. Then, the next glow plug, I noticed some sort of metal flakes.

    I am presuming my engine is trashed. I inherited this project (T-Maxx 2.5) a few months ago from a long list of my son's uncles who were all going to "fix it" over the past 5 years. They never did, and I feel lucky to have even gotten it started, let alone run a few tanks through it before this.

    I need confirmation that my next step is sound in theory: either do the trade in program, and get a new 2.5R or 3.3, or take apart the engine, and start the process of replacing piston / sleeve / etc.

    I think I'd be better off doing the trade in.

    Thoughts?

    Sounds like your engine bearings wore out, I would just do the trade in program. With metal flakes circulating through the engine there could be more damage than what is evident.

    Agreed. There is internal engine damage. Time for new or rebuild.
