#Seal

I have changed the seal 2 times on my 3.8L Chevy and it still will leak. I had a place on harmonic balancer.I put the recommended slave to repair.It was not long enough to cover the bad spot on the balancer.It was close but they seal was damaged.They offer a different one that is $30+.This all occurred just out of the blue.I rebuilt the engine and it has 30,000 on it.I was wondering if there is something causing pressure around this seal.Pressure check on cylinders was good.Any ideas what to do or pressure is good too good.

Thank you sincerely – Robert

Sajeev – you wanted questions, I have questions! First – I love your column. Great advice, and well written. Now my question(s).

1. I have a 2009 Nissan Xterra 4wd, X model, 52k miles, and no problems except door squeaks and rubber molding which wont stay attached but that’s trivial. My question is, when should I have a “tuneup” done – i.e., change the spark plugs. Should I wait until Nissan’s recommended mileage (105k miles I think), or do it sooner? And should I replace all the coils at the same time (I presume the truck has a coil-on-plug ignition setup)? What else should I have done at the same time?
2. Re: same vehicle: at 36k miles (May 2013) I did a transmission fluid dump and refill at local dealership, and did the same again at 49k miles in May 2014, again at dealership. My plan is to continue this dump and refill procedure every year for as long as I own the truck. Am I on the right track here? I’ve also had all other fluids replaced, except brake fluid which will be replaced when I have a brake job done.

Thanks for your advice, and keep up the good work.

Sajeev,

In the years since I last wrote to you my personal circumstances took a few turns. When the dust settled, I ended up with three cars. I decided to keep all three cars. The Cobalt is my daily/winter driver, and I will drive it to the ground. My wife loves the Mustang: we drop the top and take it on a cruise, she loves it, and it gets us out of the house.

About a year or so ago, I was feeling sorry for myself, traded the Impala in, and bought a new 2011 2SS Camaro with a six speed. It is a very cool car. If I’m having a bad day I pull it out of the garage, detail it and look at it. Once in a while, we may take it for a drive. Those drives are getting more and more rare. Less than 8000 kms on the clock, but I’m not planning on selling it. That may change, but not for a while…
