Diesel rx glow plugs are questionable at best. I know at one time they were using wellman automotive products, or WAP to manufacture there glow plugs. WAP is the infamous POS glow plugs that SSdiesel sells. I know in the DURAMAX world they have caused more than a few to have no starts.I´ve kept the bad glows somewhere - I was thinking I was gonna try to return them, but in the end of the day I can´t be bothered. I ordered mine via RockAuto, so maybe it´s worth a shot? I´m kind of thinking it´s gonna cost me more to ship them back to the US than the refund would be.
It´s really irritating though - In the end of the day, it cost me more than to buy them all at the local dealer. They sell the rx glow plugs, it turned out. He said they were self-limiting, so I´m hoping that´s true. I haven´t really read anything to prove it, though..
If you are not opposed to shipping there are a couple of places I use. One place you can find in a search here - in Michigan I believe - I posted up about getting injectors rebuilt there. They did an excellent job and others have used them also.I can't find anywhere to test thr extra injection pump I have let alone test injectors..lol... . How do you guys find places thst do it??
