As I have stated in the past I do have blue smoke coming out of the exhaust. Now the car runs fine but the smoke is there especially when simply light pedal stepping around the neighborhood. On the highway no smoke not even after I stop.

I have been thinking about doing the SEAFOAM treatment through the gas tank, crankcase and the brake booster line. I wanted to do a whole can in the gas tank, half in the crankcase and half through the brake booster. I spoke briefly with Wes and PMQ about this and have heard pros and cons. I would like the advice of everyone especially the senior guys and the techs.

Keep in mind that I have thought about doing this process several times to see if it makes any kind of difference/improvement. All suggestions and opinions would be helpful.

In all seriousness, I have had guys on my maxima mailing list do it with no adverse effects. Never hear much complaints with seafoam users, yet, with 169k on the clock like you have, i would be leery of running anything in it.. Yet, you have some issues with smoke and you are looking for solutions. maybe the more advanced have some info to chime in..

1. Seafoam can only do so much... Everything is so dirty only a manual clean will get it as new (as far as intake is concerned)

2. The damage is already done..... Doubtful it will get better...

My partner had a 275,000 mile Acura Legend. It burned so much oil, he never had to change it. He just added oil once a week. If we stopped in traffic, the car would literally dissapear. He went to Jiffy Lube, and they put some kind of treatment in tlhe oil, and it stopped, for about 2 months. He drove the car for another year, and I never saw smoke again. He just kept treating it, every so often. I think the treatment was about $30 to $40.

But if you remember the name of the treatment I would give that a shot.

"Laws that forbid the carrying of arms . . . disarm only those who are neither inclined nor determined to commit crimes . . . Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man."

A few other things you might want to take note of:

-Seafoam removes carbon buildup from valves. On older higher mileage engines this may be a bad thing because the carbon buildup helps engine compression.
-Do NOT let your engine suck in the Seafoam. Pour it in slowly yourself. If you let the car suck it in and let it stall itself it may hydrolock.
-change your oil and clean your plugs immediately following the treatment. Also keep an eye on your O2 sensor, as all that crap blowing through the exhaust can foul it.

Jim tells how to use it

I've used Sea foam before. Did a can in the tank, half in the crank case, and half in the intake. With that being said, I won't be using it in the intake again (I've found something better)

If/when you do use it, make sure you replace your:
1. Fuel filter (if used in fuel tank) - All that junk unclogging in your fuel tank will clog up your filter
2. Spark plugs - It can/will foul your spark plugs
3. Oil/oil filter (if used in crank case) - Common sense.. You don't want that stuff staying in there forever
4. o2 sensors may be soon to come. It fouled mine pretty badly.

I don't use it in the intake, because Seafoam is a liquid, and never actually foams up. So, if you suck it through the brake booster line, it's only going to get in the back two cylinders, and never really make it to all of them. What I like to use is GM or Mopar Combustion Chamber Cleaner (Can pick up at your local dealership). It foams up and will get to every nook and cranny. It's much more thorough than Seafoam in the intake.

On the topic of oil additives:

Copied from ls1tech (just because it was discussed there days ago) :

Never, ever put additives in your oil...with exactly ONE exception. If the factory tells you to put friction modifying additive in your rear end, do it. All oil additives on the market today are snake oil. At the very least, they will dilute the additive package that is in the oil as it comes out of the bottle. Yes, oil in the bottle has additives in it. And the additive package (it's a lot more than just one) is carefully engineered to achieve a certain minimum level of performance. But, not all oil manufacturers use the same additives, nor in the same amounts. It's a very carefully engineered balancing act, as some additives will actually react with each other. So, along comes Joe Lunchbucket who saw the latest T.V. commercial or the nifty new display at AZ. He buys a bottle of the new whiz bang stuff and pours it in. He has NO IDEA what's in it, much less how it will react with what's already there aside from the obvious dilution aspect (which incidentally is what you saw on the linked page from bobistheoilguy). Some additives can actually cause harm to your engine with what they use. I've seen an analysis on one (no longer on the market that I know of) that had chlorine in it. Incredible shear strength. It would allow a Briggs engine to run forever with an empty crankcase. Don't put it in your engine, though, or you'll get acid formation that is out of this world. Others use teflon, or PTFE, which is a particulate. What do oil filters remove? The dirtier the filter gets, the more it removes. Any one that uses any kind of oil additive is asking in a serious way for an expired engine, transmission etc.
