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.

      My parents visited me over the weekend. Had a great time.  I wish I lived in the same state as the rest of my family so I could see them all more often.

      Finally got around to watching Black Mirror since, you know, I'm bored because I can't work (and as much as I try I just can't bring myself to play anything game wise outside of FFXIV and a little bit of Destiny (I'm stuck at 267 and have no urge to do the Exotic quests and I really don't want to level another character right now)).
      Gotta say this is definitely one of my favorite shows now. Really love how they're stand alone episodes that have no interconnection with each other (well they seem to all take place in the same year and same world (based on little hints I picked up in various episodes) but they're completely separate stories of their own). Some of the episode are really fucked up (the last episode of season 3, while not fucked up, is pretty fucking dark and has given rise to a new fear for me (saying what it is will ruin it if you haven't seen it), still one of my favorite episodes though) and some are really well thought out and emotional (the San Junipero episode is really fucking good).
      All around it's a great fucking series (better be it's British, yeah I have a thing for British television) and I highly recommend it. Figured I'd start Stranger Things this weekend since it sounds like I'll be out of work for another week (according to my surgeon's nurse when I talked to her on the phone, I'll find out more tomorrow) and be ready for when season 2 airs in Oct.

      My mattress has been killing my back and sides for over a year now. I kept adjusting how I was sleeping, got a mattress pad, etc. Screw this thing. I bought a mattress in a box from walmart.com for cheap. $140. I thought about getting a memory foam one but I read that they trap heat too easily so I went with a Slumber 1 brand coil spring.
      Sure as hell this mattress showed up in a box. It was vacummed sealed in a bag, folded and rolled up. When I broke that plastic seal it inflated so damn fast that it made a whistling noise thru the plastic bag as I was cutting it open. lol. It feels pretty comfortable so far but I have to let it air out for "full recovery" for 48 hours. I'd have rather gotten an expensive really nice beauty rest mattress or something else from a mattress store, but I'm tight on funds. This seems decent enough for now.

      Well yesterday was fun. Had really bad abdominal pain and ended up in the ER only to find out I had acute appendicitis and had to have surgery (all in all spent 10 hours in the ER, got home at 4:30 this morning). Now I'm in pain and out of work for at least a week. At least I get Vicadin as my pain killer (whenever my mother pucks the prescription up, I can't drive for the next week so yea).
      Guess it's time to get caught up on my anime and game backlogs.
