So much Blazer maintenance, oil change, serpentine belt, coolant flush, etc.

A couple weeks ago the Blazer's service engine soon light came on. I went to Advance Auto Parts and used one of their scanners to find out I had a 'Coolant below thermostat threshold' error code. Basically, my coolant needed to be replaced and also my thermostat, then possibly the coolant temperature sensor. A couple days later I went to Valvoline instant oil change and had them do a coolant flush and also replace the serpentine belt. The serp belt I could have done myself, but the guy told me it was a lifetime warranty and they'll replace it free of charge whenever it starts showing alot of wear, so I figured it would be a good deal because I'll probably need at least one more belt in the next 3-4 years and it saved me the hassle of doing it myself in 30 degree temperatures.

The service engine soon light did not go off. I figured it wouldn't, because I would need to replace the thermostat too. Then I got snowed in at my house after a 2 foot snow storm. The car didn't drive anywhere for a couple days. Then on last Sunday, when I was about to go to the local grocery store, I noticed a gas smell. I went to the store and when I came back I noticed the smell still. Turns out the fuel line near the tank started leaking a steady drip of gas. wtf. I didn't have much daylight left so I got under the car, eventually found the pinhole leak, and I proceeded to patch it by placing a piece of cut hose over the hole and then use hose clamps to tighten it down. I must have over tightened it and it started leaking again which pissed me the hell off because at that point I was soaking wet from melting snow/ice (2 feet of melting snow) and pooling gas. After my hands went numb from the cold gas and my arm was killing me because I was awkwardly positioned under the rear differential, I decided to do a really cheap ass move and cut the finger off a nitrile throwaway glove, wrapped it around the pin hole leak, and clamped it down with four zip ties. Its held for a week now with no additional leaking. O_O I was going to take it off and hose clamp it correctly with my piece of hose, but another issue came up.

About 3 days ago, the car started making a weird ticking sound after I initially turned the car on. It only lasted for a couple seconds, but I thought it was a bad sign. Turns out it would only do it when the car was sitting for more than a couple hours and the length of time the ticking would last for depended on how cold it was outside. I went back to Advance Auto parts and had them test the alternator and battery because alternators, batteries and starters are all connected to a ticking sound during ignition. The battery and alternator were fine. He couldn't test the started because it would have to be off the engine, and on top of that he said that test would only check to see if the starter can start a car, which is not the problem because the noise only happens after the car is turned on. The guy was pretty knowledgeable and he suggested I do an oil change and use a oil filter with a drain back valve. I guess he meant anti-drain back valve because he told me I probably had oil sludge starting to build up and after the car was sitting for a while, the oil would accumulate in the oil pan and that ticking sound was the thick oil slowly making its way back up to the top of the engine. And that a good oil filter would prevent the oil from draining down completely to the oil pan, which is what an anti-drain back oil filter does. While I was there, I went ahead and bought the thermostat.

So, today, I did the oil change on the blazer. I spent the extra money and bought a penzoil full synthetic oil with cleaning additives ($28 for 5 quarts, costly), and I bought a Fram Tough Guard oil filter ($8, $5 more than other filters) which has a 'anti-drain back valve built into it'. I just finished the oil change, my coat is soaked because the tarp I put down over the melting snow/ice was a piece of crap and soaked straight through. Anyway, I started the car up after the oil change and no ticking sound. I'll find out tomorrow morning if the ticking sound is completely gone. I still need to do the thermostat, but my coat is soaked, I need a new tarp and I think I'm going to wait until next weekend when its 40+ degrees again. From what I read, a bad thermostat only causes a little worse fuel efficiency, so I figure if its not damaging the car, it can wait another week.

I don't know. But as the temperature is rising, the noise is noticeably subsiding, so I think its a temperature related issue. Unfortunately, after the oil change, the noise is still occurring. But instead of it being related to the oil, I have a feeling its the actual thermostat I need to replace that is causing the ticking sound. I won't know until I replace it tho. Hopefully if the weather is good tomorrow I'll be able to get it replaced and finish the patch job on my fuel line.

With proper maintanence, the 4.3l vortec motors in the '94 and up S/T series trucks/suvs (S-10/Blazer/Sonoma/Jimmy/Envoy/Bravada) should be capable of well over 200k miles before needing any major internal engine repair.

The main weak points on older, high-mileage 4.3l motors tend to be the fuel pump failures, and oil leaks from the oil cooler lines, oil filter and the rear main seal.

My blazer was a piece of shit. The thermostat, the lifters, power steering cooler lines, gasket leak, fuel line leak, transmission, etc. etc. This was one shittly made vehicle. I bought the blazer because of the engine. I figured at the engine will last 200,000 miles. What a damn shame that everything else with the vehicle only lasts 50,000-100,000 miles.

Try to really check out some good parts for your Blazer. Maybe you need to really change the Serpentine Belt, the Coolant Flush and give a good proper maintenance for your car in order to correct your car's performance. Try also to search into things in order to make things right for your vehicle.

For maintaining a blazer, try to pick some good parts. Like branded aftermarket auto parts like Dayco and the like. On that point, you would have some good parts as well as giving it a shot to really get things right.

      Finished Gundam SEED tonight. As cliche as it could get, I still really enjoyed it. Mecha designs were above average.... and despite a lot of recycled animation during battles, I still found them engaging and entertaining... and all the love interests swapping around tickled my fancy. Character deaths were pretty brutal as well. Its def worth watching for the average fan. Better than Unicorn, but not IBO as far as recently watched Gundam series.

      I have to get a dead tree cut down on my property. Its going to cost me $500. x_x But that doesn't include the removal. To save money I'll borrow a chainsaw from one of my friends and cut up the pieces myself. The tree is tall enough that when it eventually falls, it could hit my house, the garage, the deck, the pool (when its up for the summer) or my propane tanks so its got to come down.

      Its been a month since my root canal. I had another appointment yesterday for the rest of the work. They removed the temporary filling, xrayed it to make sure its all good, then did the permanent filling, then shaved/shaped the tooth for the crown, then imprinted my teeth/jaw line with a mold, then put on my temporary crown. Took them an hour. My new permanent crown will be ready in 2 weeks and then I'll finally be done. This root canal situation has been quite the experience. $1200 total after insurance. I have another tooth that might need one if it gets another cavity. If that happens I think I'll have that one pulled instead since its in the far back. Screw all this. x_x

      One week ago my little dog Elsa had to get a surgery to remove a few bad teeth. The vet initially though it would be 2 teeth, maybe 4 max. After they did the xray they noticed she had severe bone loss in multiple parts of her jaw and the majority of her teeth had to be removed. She has 1/3 of her teeth left.  The vet thinks it is a genetic issue that caused the periodontal disease to ravage her jaw the way it did. Shes been healing but its been a struggle. Very depressing week but shes over the worst of it now. Shes starting to feel like her old self but we're still trying to find a soft food she enjoys. More bad news is after we heard it was genetic, we checked our other dog Bella because they are cousins and she has 2 loose teeth in the front. Once we get some stimulus money we'll schedule xrays for her to see if her issue is as bad. Elsa had horrible breath going on as the main symptom but Bella's breath is fine. I hope she only needs the 2 little teeth removed. My poor babies.

      A friend was able to score me a PS5 while I was at work today. I'm pretty pumped!
