Need Some Help/Advice/Opinions...

...and I guess just a sounding board. Sorry for the long post.

A little back story. Lester's Build/Fix/Maintenance/Questions Thread

The truck isn't mine, I have just been driving it and trying to maintain it. The rear-most passenger side spark plug blew the center electrode. I replaced it with a new one and had no problems for a little while.

A week or two later, the truck was being driven by the owners daughter and then it blew. Unfortunately, they didn't take it to our main mechanic (a friend of ours) and it is at a shop of blow schmo mechanic. They already pulled the heads off, at which point they said they need to replace the whole block. I haven't actually seen the truck since the incident, so I don't know what actually went wrong or what damage there actually is. I want to go and look at it and take some pics for my friend, so I can see if I really do need to replace the engine. (The guy is a dick, so we aren't sure if he is just trying to play us.) They are saying that the little electrode destroyed two of the pistons and cylinders and that it would end up being cheaper to get a new engine than to repair whatever they say is broken.

The guy is willing to eat the $500 cost to pull the heads and pay the owner what he owes to the bank for the truck (about $700). I don't want to do that. Nobody here needs to be convinced why to not throw away their Runner. But the problem is that a new engine is going to cost close to $6,000 or more (he quoted 25 hours labor-$2500 and about $3300 in parts). My friend is willing to help me put a new (to me) engine in, but it will still cost a specific amount to get a new engine. This assumes that I really do need to change it out.

I don't want to spend $3300 in parts. I have found many engines online (mostly those JDM types engines). Has anybody done this option before? I can post links to these, but there are a million of them. They are usually between $1k and $1.5k. To me a truck that is worth $6-7k and I only pay 1-1.5 is a pretty good deal. (again this assumes I have to replace the whole thing.) I can also find some for less than a grand, because the truck was in an accident. This makes me nervous though. Some of them are side impact, but still makes me skittish about it. Those are between $800-1000 (but they have miles on them). I also found a guy who can supply a bare block for $350. If I need a new block, but nothing else, I could go that route.

Can anybody comment, I'm not really sure where to go from here, other than going and seeing the actual damage.
:cheers:

If the guy is jerking you around then I'd pull it out of their shop and tow it to your mechanic friend. It's worth the extra money to tow to have your friend look at it. You mentioned that 2 cylinders were damaged. I don't see how an electrode from a spark plug is going to damage 2 different cylinders. I don't know how you could get it from one cylinder to another. One cylinder, definitely. If the piston or cylinder really is damaged I'd just replace the engine. If the block needs to be replaced it's very likely the piston is toast as well. I'd try to by an engine from a friend or at least someone you know.

:lalala:


Geeeee considering that the mechanic can just drop a complete used engine in for $1000-$1400 (cost of an engine with < 100k miles from a wrecked tacoma) and then he will have a $6-$7K truck .... I'm sure he is WILLING to the LoL "eat the $500" cost if your buddy just gives him the truck.

First off I would just tow the truck home and then start looking for a sourced used engine. Next find a different shop to help you swap in the engine. It should not cost more than $750 to do the work.


They are saying that the little electrode destroyed two of the pistons and cylinders and that it would end up being cheaper to get a new engine than to repair whatever they say is broken.

That very well might be true in fact it is often cheaper to just change out the engine.

So I went down to the shop to take some pics. This is what I saw. I'm going to see my friend tonight to get his opinion, but wanted to know what you guys thought too.

This is the "damaged" piston. It obviously has some carbon, but it has 200k+ miles, duh. The top is pretty rough, it's not like it's smooth, but I don't see any cracks or anything that they claimed. The middle one is certainly pretty grizzly looking.

Unfortunately, the piston was up and the idiot mechanic thinks this is an interference engine, so he didn't want to move the crank, which means no pic of what the cylinder wall looks like.

Here's the whole passenger side. Again, carbonization. You can also see the exhaust manifold, with all the white stuff, which tells me there was some serious misfiring and/or improper combustion.


So what do you guys think? Whole new block, replace the pistons, just clean off the carbon? If the cylinder wall is damaged, can I bore it out with an oversized piston? Or can I bore and mill the whole thing?

Thanks! :yo:
 
If it were me, I would tow my truck away ASAP and find someone I can trust.

I have been screwed over by incompetent mechanics before and it's better to cut your losses and move on.

Sorry to hear about your troubles....good luck!!
 
When you say the engine blew what were the symptoms? Might shed a little light on the cause and diagnosis.

Hope it works out for ya
 
Stop!!!!

Don't do anything and tow it out of the shop and take it to reputable shop you know or park it at your house for now.You didn't take a pic of the heads on how they look like,i can see some pitting on the left side of that last piston but hard to say if it scored the walls the second piston seems normal for it's mileage.Piston can survive a beating as long no damage to it's edges and wall scoring don't rush into any repairs until you get a 2nd or 3rd opinion.I'm in the East bay and could help you out if you need to.
 
Dude (again)

1) tow it home ASAP.

2) source a decent used engine for $1200 and call it a day

3) no need to do an expensive overhaul when you can just replace the whole engine for $1200
 
Thanks for the replies guys. I realized right when I posted the pics that I hadn't taken a pic of the head. Oops. Until tonight, the question was not a matter of towing, but rather it was worth selling the truck to the guy or not. Until today, I had not seen the damage, so I was going on the word of the mechanic through the owner. Obviously his word means absolutely nothing.

So after taking pics and talking to my friend tonight (showed him the pics), he said he could not tell from the pics the exact course of action, but it is definitely fixable. So I will pay off the $500, get my parts back, tow it home and will have to wait until his garage is finished being built. (I help him finish it, he helps me fix the truck, all labor is 'free' - sweet trade, if you ask me.) So we will take a closer look and see what we need to do from there. If I can fix it for a few hundred, instead of $1200 or more, then I will gladly do that.

I wasn't driving the truck during the 'incident' and until today hadn't seen it since then. The person driving said it felt like the choppiness of a motorcycle and the engine was about to die.

I appreciate the replies guys, will keep updating as things progress. Now that I was able to look at it and talked to my friend, I will be getting the truck out. Don't know when I'm going to tow it out, but I definitely want to do it ASAP, just need to work out the logistics (especially where to park it, while the garage is finished being built).
