Did you know? We Can Rebuild and Tune Carburetors. Did you know New Carburetors do not come tuned out of the box, and most need to be re-jetted for our altitude prior to installation?

I want to share some photos and some advice. This may be a controversial post. Opinions can obviously differ. In these photos are various control arm bushings in various states of decay. I see some shops are telling people this is a major priority that must be addressed right away.

In my opinion, all of the bushings here have life left, and none are a safety concern at the stage pictured. In our climate, the rubber tends to dry out fast, and you will get these sort of cracks relatively quickly, even with new control arms or bushings, it may look the same in a year or two. Keep in mind, all of these photos show bushings that another shop said MUST be replaced ASAP!

Even if the bushing were to fail completely, the arm is not going to fall off, it is captured by the metal control arm surround, and the bolt in the center.

It is ideal to replace them before complete failure, and I would suggest checking them once every 6 months if the tear becomes more than 25% of the connected rubber, and replace them when the tear is closer to 40% or 50%. of the total connected area, depending on the style of bushing.

Finally, the most recent car that prompted me to make this post, had arrived with a quote in hand for $3000 for two front control arms!! I am reasonably priced, but also priced as a quality shop, and I found about $670 per side for parts and labor, or about $1340 for the pair, way below the 3k he was quoted. Get a second opinion!!

This information is for Gasoline Vehicles, and not all of the information relates to Diesel engines.

I am constantly amazed by how bad the engine oil looks on so many of the cars we inspect. Engine oil turns dark black when it is filled with dirt and chemicals from combustion. Once it gets to the point of being completely black, it can no longer hold any more dirt, and sludge will start to form in the engine.

Oil can turn black early due to a few reasons. One is poor quality oil with lower amount of deteergents and less of the chemicals that absorb the harmful acids formed on a cold start. Another reason is built up dirt form previous oil changes when the oil was alloed to run dirty long enough to start leaving dirt inside the engine. Yet another cause is poor performing or clogged PCV system.

The PCV or Positive Crankcase Ventilation system is designed to remove the harmfull gasses from the crankcase/oil pan that are formed from compression blow-by. When the PCV system is not working properly, these gasses can ruin the oil faster than it normally would.

If your oil is turning black before it is time to be changed, I recommend you try to play catch up and get all that dirt out of the engine.

1st. Make sure the PCV system is functioning properly. Check for a slight vacuum at the engine oil cap when the engine is running. Excessive vacuum , or positive pressure, can indicate a PCV problem that should be address ASAP.

2nd. Start checking your oil every 500 to 1,000 miles. Change the oil when it starts to get very dark brown. If you are using a quality brand name oil, you will start to see that the oil stays clear for longer intervals. Eventually once most of the dirt is removed, the engine oil will stay clear or light brown for the entire oil change interval.

If you find your oil turns black before even reaching the 500 mile mark, you may want to perform an Engine Oil Flush to give the engine a more aggressive clean out and try to hasten the process of removing the built up dirt. I recommend Kenz & Leslie - BG Products for the Engine Oil Flush.

This information is for Gasoline Vehicles, and not all of the information relates to Diesel engines.

I hope that all of this information helps you keep your car or truck running longer. I have several of my own vehicles, some of them shop loaners, that have over 300k miles and are still running strong.

Do you own an Audi, Volkswagen, Dodge/Jeep ot other car with a plastic transmission pan? If you are thinking of servicing the transmission fluid and filter, why not upgrade that plastic pan with a non-serviceable filter to an aluminum pan with a filter that can be replaced in the future? Ditch the plastic and go back to metal!
