I'm having an ongoing problem with my glow plugs failing, can someone answer the following questions 1. Will using 3 in 1 oil on the air filter cause glow plugs to fail? 2. Will driving in a field with average length grass (1" high) and up a hill so the car struggles to build revs in second gear cause glow plug failure? 3 what glow plugs fit my 3.3, I want to try hot glow plugs but eBay has thousands of variations (there are no traxxas own brand hot plugs on eBay that are in England) I have been buying #3232x they last. About 3 tanks!
