So my 4.3 V6 that I was planning on stretching to 250k before getting a new vehicle was murdered yesterday. I say murdered because the problem was NOT due to negligence or ignorance, but rather a mistake made by a shop mechanic...

A few weeks ago I had my guys at my shop (who I trust and highly recommend to everybody I know) fix the fitting on my oil cooler return line. It had been dripping for a while and I was tired of seeing stains on the driveway (and having to clean up stains on the driveway) so I forked over $75 to have it done professionally, since I know how important that function is and because I didn't want to deal with that messy of a job at the time.

So I go to drive my car home after leaving it sitting for a day (this is Sunday) and began my 4 mile drive back to my house. I had been driving a 2013 jeep wrangler for the past day and was used to a bit more horesepower. I went to try to pass somebody and gave it some gas and revved it to 2000 RPM which took a lot of throttle. I have a scangauge and it was reading 47% throttle position before I got up to 2000 rpms. I rolled down the window and cut the music and listened and heard something that was not good. With a mile left and no where convenient to stop, I tried to make it home. I quickly realized that it wouldn't happen so I tried to make it at least to the next parking lot. Got caught at the red light and my engine let out it's final exhaust of its life. It was toast.

There was smoke pouring from the engine bay and when I looked initially saw tons of oil all over the drivers side of the engines. I had figured I had blown a head gasket or something? Last time I heard of a head gasket blowing there was no oil coming out though. Oil pan gasket? **** man, I just had to get the car out of the middle of the road. Pushed it into a starbucks lot and called my uncle and he came by.

After further inspection (removed the air box) I saw TONS of oil thrown all over the engine bay. I couldn't figure out what it was, since the passenger's side was completely clean. I let it cool because it was way too hot. After grabbing the strongest cup of coffee possible I went out and noticed that there was a lot more at the oil right next to the oil cooler return line fitting - the same fitting that was just worked on two weeks ago. I was ****ing furious.

I was mad for two reasons: 1 being that I just paid money to have something fixed and it ended up ruining my engine. 2 because I JUST did my spark plugs, spark plug wires, distributor cap, and rotor that weekend. I changed my oil and oil filter to royal purple a month ago and that stuff is NOT cheap. $41 for the 5 quarts of oil and $14 for the filter. But, I was taking care of the engine because it took care of me.

Spoke to the guys at the shop this morning bright and early after having it towed to their front door (almost literally) Sunday evening and my guy said he'd give me a call. Around 2:00 we spoke and he said the engine is locked up. He told me that he had a funny feeling about our situation because he's never seen that fitting fail on anybody like that before. He asked me some questions about my differential (new shiny cover on it) to see if it was done at another shop, which it wasn't (I'm guessing that was to see if the oil line could've been messed with at another place). I do as much of my own work myself and have the shop there for when it's over my head or I don't feel like being covered in grit and grime that day.

He told me that he found a used engine from a supplier that they trust and have used before that has 102k on it. My vehicle has 184k on it, so the engine is almost half as young as far as mileage goes. My worry, though, is that I don't know if this engine was maintained or not. I don't know if it was owned by a grandma who never pushed it past 1500 rpms or if it was a dumbass kid who redlined it all the time. I don't know anything about it. He reassured me that they'd check it and manually crank it to get a feel for it and everything. I'm going to ask them if they can compression test it and see how it does. I don't think that'd be out of line.

If you've made it this far in this post, thank you for reading this. It really sucks that I spent the past two years and 35,000 miles taking the best care of this engine and vehicle as possible and then the engine is shot due to the carelessness of a grease monkey.....but I suppose that is just part of life.

Any advice/comments/concerns/tips for me from you guys?

 

Does this shop have a warranty on their work? If so, see if they can cover partial cost, of a new engine. Then I would get the engine, and never go to that shop again. That is an expensive screw up there.

Also, dont waste your money on royal purple, I have heard that oil is not worth the price at all from multiple people.

But that sucks the engine went.
That is the main reason I completely removed my remote filter and put the filter back on the block.

 

I'm supposed to be getting my vehicle back tomorrow afternoon. I stopped by yesterday to grab my scangauge out of my center console and saw the new engine. it had some rust on the front of it but other than that it looks very nice. no oil leaks or anything. All i am paying for is new motor mounts, since the old ones fell apart when they took the old engine off of them. $100 for an even more stable engine without oil leaks and a (hopefully) 100% fuel pressure regulator? sounds like a sweet deal.

He's putting amsoil in it as well. They're really taking care of me.

 

I am glad that they are taking care of you, now that is a good shop, most would be like "it wasnt us, its not our fault, not our problem" but they are helping you out, and getting you right.

There needs to be more shops like that.
So i retract my previous statement.

 

Ditto, that's a good shop.

 

Okay... got it back today.

It feels sluggish (probably because that engine was sitting for a bit) but I feel that after a few oil changes it should be in shape.

ONE PROBLEM THAT SUCKS REALLY BADLY
the engine appears to have come off of a silverado. why is this bad? because the dipstick tube in those is WAYYYY shorter than the one in the blazer. The dipstick is underneath a bunch of hoses and wires and is nearly impossible to get a good reading off of because you have to rub it up against the hoses/wires to get it out.

So.... do I go and complain to them and have them do it? Or do I buy another dipstick tube and just put it on myself? The weird thing is that even though the tube is about a foot lower than it was, the dipstick appears to be the same length. Why? no clue. But I'm afraid that even if I COULD get to it without hitting it on the hoses then it'd be way too high.

Help?

 

May have a deeper oil pan
