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:

      I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.

      An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?

      There's a bunch of tea leaves that you've read, but in any case the delayed timing is unusual. Not sure how that relates to the rich at idle vs. 'normal' while driving.   If you're in this deep, might be worth investigating, and re-learning the sensor. What have you got to lose? Plus, it properly fixes the timing cover leak.

      The only problem I have seen this cause is longer crank times.

      Injector is being sent off today for rebuild and I estimate I'll have it back in 10 days or so.   It may not be the injector...of course...now that I've torn down the intake again. But, let's rule out the injector and replace those spider legs that have been almost rubbed through.   The truck has always had negative timing and I'm reading "normal" timing at warm idle should be +16 or so. I'm negative 16 to 25 or more, and it's always been like that since I bought it.   A light turned on upstairs last night in the old noggin. Rare, I know...   This will be wild, if it turns out to be the cause!   In 2001, according to the old service documentation, the muffler was replaced. Why? I have no idea, it wouldn't have been rusted through by then. But they did a crappy job.   In 2019, another shop replaced it and noted the prior install was poorly done on the work order. "Exhaust system vibrates on crossmember". Except...I guess they just left it be? I believe the husband, the couple who were original owners, had passed by then. Maybe she said it's just not worth it to have the exhaust system fixed and declined repairs. Very few miles were driven between 2019 and 2025.   The exhaust system vibrates heavily on the crossmember and you can feel it and REALLY hear it, even today. Not always, but at idle, it gets going pretty good sometimes.   What if....   ....What if that's enough to trigger one or both of the knock sensors? Could it be tricking the sensors into sensing knock, so it's pulling timing aggressively? Pulling timing heavily means it's firing after the piston reaches full height which means incomplete burn which means the O2 sensor is sensing a rich condition, which means I've been chasing my tail, and what I thought was an inconsequential problem (janky exhaust) has been THE issue for this truck for 25 solid years?   That would be wild. Maybe it IS wild.   The service documentation thereafter, for years, shows visits for rough idle, replacing O2's, replacing the cat, replacing plugs and wires, a misfire condition, like they could never solve the issue. The injector has been replaced 4 times in 80k miles, that's just crazy.   The secondary theory....   The engine has clearly had a leak at the front seal for a very long time (the greasy trench...). I think the truck changed hands quickly ~2025 because there's Napa receipts from someone I don't recognize in the ownership history. They apparently replaced the timing cover seal, and they did a terrible job. There's RTV smeared all over and the leak I had reduced to a weep by snugging the front oil pan bolts is now a leak again.   HOWEVER....I read about replacing the crankshaft position sensor. Any time the ckp sensor is disturbed or timing cover is removed, the truck requires relearning, and that can only be done through a bi-directional scan tool. Skippy with the RTV probably didn't do the relearn procedure is my guess. His scan tool is lost in a pile of RTV goo somewhere.   So, it's very possible the sensor has been disturbed and the truck is just running on the old learn data but not setting a code for anything. The distributor has since been replaced and so has the camshaft position sensor, so all bets are off for that thing.   In the theme of one step forward, two steps back, I returned the accumulator for the AC. The gal I've been working with at O'Really's has been great. She refunded it under manufacturer's defect and we compared it to the replacement I ordered, and sure enough, the replacement is machined very differently (and a gauge actually fits on it!).   Got it home, installed it, started vacuuming it down.... and I couldn't get good vacuum.   The high side service port, where I replaced the old GM ball valve suspecting that was a source of the previous leak....well, I've clearly exposed whatever pre-existing crack in the line where the service port is welded, and made it much worse. Blessing in disguise? Except there goes another $25, now I'm waiting for a replacement AC line.   In 10-ish days ALL the parts will be here. Rebuilt injector, new exhaust system, new cat, new high pressure AC line.   Oh, did I mention the squeaking ISN'T coming from the AC pump? The truck still squeaks when started, and there were words after I started it with the new AC pump installed. But, there was more to replacing the AC pump for just a squeak. A truck with good working AC is something of value, for the comfort alone.   I've ordered a new harmonic balancer because, 30 years is a good run for one of those. Rule it out. The squeak may be something more sinister, though. I'm worried about that ckp sensor and if it was shimmed correctly, or if the timing set was installed correctly. The squeak may be coming from UNDER the timing cover.   At this point, once I get it put back together, I'm thinking I'll take a 50 mile victory lap and then promptly put it up for sale. This truck is cursed. Betty, from beyond the grave, doesn't want anyone messing with her Blazer. Or maybe she's getting revenge for 30 years of shop visits with that thing.
