In the last couple of weeks I notice some blue smoke when I am idling. It only happens when idling and engine is warmed up. I have 80,000 miles on truck and this is the first time I am having trouble with it. I changed oil and filter and also fuel filter. I keep on looking at the oil level for possible fuel leak into sump. No change. However, it might be too early to tell because I only have 70 miles on it since the last oil change. I use the right specifications and viscosity for the oil. The air filter is an after market K&N filter. No trouble codes are displayed and it gives me a "no codes" on my OBD II scanner.
Please, give me your thoughts. Would it be advisable to drive home, about 2000 miles, or should I have it repaired asap. Also if only one injector leaks should I just replace this one and don't worry about the rest.
Planning to have it scanned today to see what the injectors are doing. I am evaluating to see if I can drive it home to British Columbia where I have the tools and garage to work on it.
Thanks, BriteWhiteRam for your input.
It shouldn't hurt it too badly, but just be nice to it, check the oil periodically to make sure you're not getting oil delusion, You can probably just replace the one or more that are bad, replacing all 8 would hurt
