Finished the Sportsman 700 clutch install, got an ice-auger running, and to start the morning off, I rescued my sister-in-law and her '04 Olds Alero.

 

The Olds has the 3400 pushrod V6. Only 64k miles! Thing is a time-warp - mint condition for up here. She called in hysterics this morning - had to be at work, and said the car was knocking LOUD. Oh boy .... So I get down there, had her fire it up - YUP! That's a KNOCK! Holy crap was that bad - sounded like someone was wailing on the rear valve cover with a 4-pound sledge. Could hear a dead miss too. I suspect a rocker stud yanked out of the head, and the pushrod was just slamming the rocker against the valve cover. Threw the scan tool on just to see what the light was, hoping it would tell me which cylinder can't breathe. The knock was so bad, it threw a random - P0300.

 

I didn't bring the trailer, and I figured the damage is already done, so I had her follow me back to her apartment, which was only 4 miles or less up the road from where she stopped. When we got to the apartment, she said it wouldn't go over 40 MPH - may have made things worse. We'll see soon enough. She was going to call in to work, and I advised against that - told her she'd need all the money she could get to fix the thing.

 

Going to run down there sometime this week and tow it back here. I'll probably end up doing it labor free. Their financial situation isn't what you'd call golden. It's all good. I have the ability God gave me, so gotta give back sometimes - that's how it works. :)

 

Should be some great pics to follow, I can imagine! :lol:

 

 

 

Here's a pic of those Polaris clutches - one is new, the other is old (primary) - funny thing is, the new one in the foreground has no spring in it - that's how it will sit with no tension to force it back. The old one in back there is fully assembled! Spring doesn't have enough power to overcome the corrosion on the thing. It looks like it came out of the ocean. :lol:

This morning we drove by Lambeau Field and boy it really is in a field.

I'm going to be needing to do mine again real soon too. 30k hard miles on them. When I put the Blizzaks on, they were about 90% worn.

 

Just got back with my SIL's Olds Alero. Had to shuffle a bunch of stuff around in the barn to make sure I could get to a couple snowblowers and an ATV while that thing has the engine opened up. My ears were ringing trying to pinpoint the knock - man, is that bad! Has less than 64K on it - 63k and change.

Hard to tell how bad the noise is from here but I will guess that it is a wrist pin failure........have you done the tear down yet?

Posted

Not yet.

 

Doesn't sound to me like anything in the block - it's a very sharp, loud metallic whack - just like if you took a ball-pien hammer to the intake manifold. When I first heard it, it was constant, going at the speed of the cam. Now it's intermittent - when I fired it up to drive it on the trailer, the noise would come and go, but the dead miss was very apparent at all times.

 

Unless of course I've been hearing the piston smack the head - that's entirely possible!

Going to attempt a vid upload ...

 

No idea how to get the damn vid right here in the post - would be easier to view I think. Whatever. Here's a link, at least:

Man that sure sounds like it spun a rod bearing and the piston is hitting the head.

Posted

Definitely not a rod bearing, unless the thing just completely fell out of there, lol. I think the audio in the vid isn't true to life.

 

If you listen to the cadence of it (the engine is idling at 1,100 rpm), it's in time more with the camshaft. The other noise is just the dead miss shaking the thing around so much.

 

We'll find out soon enough ... :lol:

Ended up being exactly what I thought. #1 exhaust rocker stud yanked the threads right out of the head. Thankfully of all the valves on the rear bank, this one is the easiest to access.

 

On a 63, xxx mile engine. YIKES! :nonod:

That's not a spring there - that's the threads that came out with the bolt! :lol:

Rolled 68k earlier

Miles are adding up quick. If I wouldn't have wrecked it and lost it for 3 months last year I'd probably be around 80k right now

    • Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!
    • If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.
    • My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.    
    • I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w
    • I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
