Hi, replaced my glow plugs last weekend and two look really strange. Last summer the mechanic had the car for two months and returned it running better, but not perfect and said something was wrong with #4 but could figure it out. It smokes a bit, keeps excellent oil pressure (even when hot) has 220K (actual) on it, and seemed like it was missing. Last spring I did a compression test on it and four of the cylinders were in the 310-320 range #4 was lower than the others (290). Perked up with a little oil squirted into it. Figured I'd drive it. With weather getting colder and dash glow plug light no longer working, it was time to replace the plugs. Reamed out all the plug areas, and replaced with new. Car started much easier, but still smokes quite a bit. #1 plug looks like the tip is bent. Hard to tell from the picture, but #4 glow plug looks like the end was flattened an someone cut a "v" into it. My injectors are have less than 20K on them, but could this be caused by bad injectors dumping fuel on them?

Thanks,
