I am new to the site and hope you can help. I have a 2001 Ram, 2500 V10, 53k miles, auto trans.
When pulling my 31 ft trailer down hill and using the engine to help brake (1st gear) my truck smokes (a lot). I will let the RPM's get to 3000 before braking sometimes. I think the valve guide seals need replacing but would like some advice before putting hours into replace the seals. Normal driving doesn't show any smoke.
Thanks for the help.
