Ridiculous Engineering

OK, I am on my soap box tonight. I just got through changing oil in a 2006 trailblazer I had bought my daughter this summer.

 

Holy Mother of God contortionists could not even change the oil in this thing!!!

 

No wonder GM is in trouble. This is just plain stupid.

 

Ok, I want even go into the fact that the vehicle has only 48,000 miles on it, and I have already had a leaking steering sector and had to replace the water pump. Lets just say that was maybe a bad coincidince 2 bad components on the vehicle.

 

BUT THE DAMN OIL CHANGING?

 

First, I have to remove what I guess is a protective cover (What it protects I don't know because it is plastic)

 

Now, I will admit, the drain plug is right there....however, my drain pan holds 6 quarts. Now being a REASONABLE MINDED person, I assumed since my GMC 1500 V8 held 6 quarts, then this little 4.2 liter 6 cylinder would hold 6 or less. I release the plug, go to getting the filter wrench and filter ready. I look back and the 7th quart is all over my shop floor.

 

Ok, I chalk that up to being stupid for not looking for the capacities.

 

But now I go to get to the filter...where the hell is it? OH, there it is, up between the frame and engine where it looks like someone had to drive it in there with a 10 lb sledge! After about 10 minutes of cussing, and modifying the bejesus out of my filter wrench handle....I finally get spin! Now, I assume the worst is over....nnnoooooo. There is no way on God's green earth to get the filter out without oil dumping all over the frame and the "protective" plastic guard on bottom of the frame. Oh, and it also runs down your arm and into your armpit. (Do not ask me how I know this)

 

Ok, got it off. Now, I grab the new filter, and turn my arm into a position that makes me look like I got cerebral palsy, and finally get threads to make even contact. But now I can not get enough wrist strength to tighten it up. So, I unmodify the filter wrench from "take off" and remodify to a "put on" angle. A tug on the wrench, and I am there.

 

Now, I replace the plug, and the protective plastic cover that is now covered with oil from the filter removal. A quick pour of 7 quarts of 5w-30 into the crankcase, and finally, 30 minutes later, a 10 minute job is done!

 

My only comment is that my 9 year old grandson could have done a better design. And they wonder why they are losing market share......

 

Now, during this episode, I almost forgot what happened when I removed the drain plug for the first time on my GMT900 Sierra, but that is another story, one which I do not have time for, but which also required large quantities of Oil Dry.

 

I also own 2 dodges, and the oil changes are a breeze. Everything is easy to reach and work with.

Damn that was a good one. Sorry for your troubles but thanks for the laugh.

I agree. Changes on mine take a whopping 5 minutes.

I rank "ease of oil change" right at the bottom of the list as to why GM has lost market share...But that's a whole other topic.

 

Which engine do you have in there? I've changed the oil in a few Trailblazers. A couple with 5.3's in them, and my 6.0 liter Trailblazer SS. I never had any of the issues of which you speak.

 

Oh...And it sounds like you need a different style filter wrench for that vehicle. NEW TOOL! WOOOHOOOO!

 

/has about 8 different filter wrenches

I have changed the oil of several trucks from ford 150s to dodge 1500s. i would have to say i hate changing the oil on my sierra more then any of the other trucks i have worked on. lol still not a reason why gm has lost market share.

although it IS a stupid place for an oil filter... if you take the right/front tire off (maybe do a tire rotation) you can easily get to it with an oil filter wrench to loosen/tighten it.

 

If you're in a shop with it on a lift you dont need to take the tire off.... but laying on your back im not sure if it'll work as well- hence, it may just be easier to pop it off.

 

It is a PITA where it's located though, especially cleaning the oil that dripped down onto all the plastic and crossmember

As I stated in my post :dunno: , it is a 4.2 liter 6.

 

And the market share remark was sarcasm. But with engineering like that, you wonder what the stuff you can't see is like... :dunno:

 

And I still can not figure out the 7 quart thing, when a V8 holds 6. :jester:

I'd wager your Silverado has more room under the hood than the Trailblazer does. :jester:

 

Just be lucky you don't have a smaller car yet. I drove a Chevy Citation in high school. It was a 4 banger with the engine turned sideways (it was FWD). Now THAT was a PITA. :dunno:

Yeah, I agree with you.

 

I don't think "I'm a big puss when it comes to changing oil" is an option on the reliability ratings.

 

Some people find the dumbest things to bitch about.

I wonder......do tears and oil mix when spilled onto the floor? :dunno:

      OCI, not when but why?

      By Grumpy Bear · Posted

      The filtering to wear relationship goes like this:      'Relative Engine Life "Factor" new divided by the factor old. So 8/3= 2.67. That result is the multiplier thus if a motor had an effective life of 100K using a filter with a 45 micron rating at a Beta ratio of 75 then a filter with a micron rating of 10 at a Beta of 75 would improve expected engine life to 267,000 miles.    Wear metals are an indirect indicator. Less is better and the motor lives longer but there isn't a multiplier like there is for filtration so well documented. Most of that has to do with the sensitivity of the wear metals tests themselves. The read a 'slice' of the spectrum but not the absolute values for the entire spectrum. So a general indicator that is used WITH the results of other tests. Two others considered in this post.    There is also the influence of corrosive wear which may be seen in the wear metals but separate from load based or viscosity mitigated indication. It's a small graph but the gray line is wear vs the TBN/TAN crossover. Not as useful as it used to be as there are now new chemistries for acid remediation that don't show up in standard UAO testing. They will catch up or be found liars. Only two possible outcomes, eh?

      One thing that comes up over and over is that the torque converters are the weak link. Many of the failed transmissions have the same thing in common. The torque converter grenades and then metal torque converter shards end up destroying the transmission. One of the best things you can do is if your transmission is still fully functional, change out to one of the aftermarket billet torque converters. There are several good choices mentioned in different threads here to make your choice. After that, then you can decide about trans tuning. My trans failed at around 95,000 miles. It got replaced under the GM protection plan. The remanufactured trans comes with a 100,000 mile /3 year warranty. I still have just under 1 year left. So far, so good. As long as it's still working good next year, an aftermarket torque converter is going to get installed early spring. If the trans and OEM torque converter fail by then, I will get it replaced under warranty and immediately have an aftermarket torque converter installed. A warranty replacement trans of a replacement trans will no longer have the warranty so I will bulletproof it from the get go.

      Pushing $4.00 a gallon in most places, still $3.75 in town but it's going to spike tomorrow for sure.   Diesel back up to $4.60-5.00.

      LCA bolts

      By calgator73 · Posted

      I really appreciate the response.  I guess I was confused about torque angle vs torque angle yield.  The individual bolts don't have a warning on reuse but the part number for the LCA nuts does.   Regarding the purpose of the moog grease fittings on their bolts .. Guessing to reduce possibility of corrosion locking the cams or seizing to the bushing inserts.
