SOLVED! Post 2853 Leaking Injectors, Dealer Techs Rock! Extended Cranking after Engine Swap 3.4L 5vz

Anyone want to buy a Tacoma? I'm done. Now all the naysayers can have their party, woo hoo, you win. HURRAY FOR YOU!

 

Thanks K. The one bright spot of my morning, that someone who can't wait to gloat about how right they've been from the start DID NOT TAKE POST #1000. Appreciate you looking out for us buddy

 

Thank you Keakar. Yes, I understand, you think I am a total fucking idiot. Got it. Feel good about yourself? Wait, edit - that I am a happy total fucking idiot. Yep, that's me.

 

EXACTLY. Thanks again K

Ha! Took me a minute, then I read between the lines. Appropriate settings updated. Thank you! Maybe I can hang in there after all.......

 

Thanks Bama. So what does this mean exactly in relation to our situation?

 

Pressure can be high in a no-flow condition, but if we look at both no-flow pressure and VOLUME output, I think we can properly analyze simple hydraulic system.

For instance, a good pump can pressurize a 6" pipe, but now put a plate with 1/8" restrictor hole, you still have good pressure between the pump and restrictor and good static pressure AFTER the restrictor, but terrible flow after the restrictor. Isn't there a pressure regulator in the circuit between the pump and injector?

 

What that means is that we honestly need to wait until the mechanic find out something from the injector guy. Personally I think that the cost of replacing them will end up being less than the total cost of cleaning them by the mechanic's injector guy. If memory serves the link I had posted for the matched set was only $170? I think it was. When they come back to you with the estimate to clean I would weigh that in with the cost of replacing them. Once that step is taken care of we can progress from there. I would suspect that a new fuel pump will have taken care of the fuel SUPPLY issue. The injector situation should take care of the fuel distribution problem, and I would think have you back up and running. Of course I can only make educated guesses here.

On a side note, don't let yourself get frustrated. I have been there and know exactly how you feel. A lot of the guys here have come up with thoughts and suggestions and can only do what I have done, and make educated suggestions on what can be the issue. I am sure keakar was not in any way trying to be rude. Remember that he has given a LOT of good insight into the situation. You have to deal with a dozen guys on a forum who come up with suggestions, as well as two different mechanics who are there in person with your truck. I certainly do wish that I could come up and take a look at it. Obviously that is not really an option. lol. Besides, it's too dang COLD up there in Oregon! Hahaha. I will say this: If this was my personal truck, or one of my customers, based on what I know at this point, I would tell them to buy a new set of injectors and replace all of the old ones. I know a ton of money has already been spent on this truck, but at this point the $160 would be money well spent. Especially since he already has the old injectors out right now.

 

There is a FPR between the pump and the injectors. As I recall it has been replaced during the current diagnostic issue. I personally think that the FPR is is good shape. But then again, I'm not able to test it. lol.

 

I cant believe you are happily making the same mistake you already made the first time

Yes, clearly not trying to be rude. For sure. Quite a concerned, supportive statement.

Maybe he's offered good advice, but if reading statements like the above is the price I have to pay for that advice, no thanks.

Not kidding. I'm done. Advice on how to get rid of it and not lose every penny we've spent?

 

To be honest, with the new engine cost and the fuel pump, etc. There is no way you can sell and recoup every dime. I would just stick to the grindstone and push through. Don't let your thoughts take control. Be looking on the logical side of it all. You are almost fixed I think at this point. It would be like swimming 7/8 of a mile across a 1 mile wide river and saying "I can't make it" then turning around and trying to swim back. Jen, keep your chin up! I can tell you that once this is done you will be happy that you pushed on. The Tacoma is a truck worth having. I think you will grow to love it even more once this is done. Please, just hang in there!

 

I do not understand how a rebuilt set of injectors off of Ebay is somehow superior to rebuilding our set by someone who does that, and only that, all day, every day.

 

OK. And I get you on that. I was not trying to infer that the injectors from the seller on eBay were superior. My apologies if I gave that impression. I don't know the guy that is doing the rebuilding for your mechanic. Thus why I mentioned that once you get the estimate back on getting them rebuilt by this guy, to compare that price to the price of buying a rebuilt and flow matched set. I don't know if the mechanics rebuilder will have your old injectors flow matched or not. So my suggestion is based on comparing the costs of him doing it, versus buying a replacement set. Kind of like going to the grocery store and buying apples: Store A is selling you 6 apples for $2. Store B will sell you the same identical apples for $1.50. It's the same product, just a different cost. So wait and see what the mechanic says about the cost of his guy doing the rebuild, and what kind of warranty he will give.

 

If you were going to get out of this truck, the time to do that was when the truck first required a major repair. That is why I rarely do engine or transmission swaps on the vehicles I've owned. Sadly it rarely works out to the point where you feel like you've spent the money wisely a few years down the road when the truck needs it's next major repair.

That being said, if any vehicle is worth the amount of time, effort, and stress you're going through it's a first generation Tacoma. They are excellent trucks and not exactly replaceable. Good luck OP . You need to roll with the punches at this point.

 

Thanks Bama. I did research the place our mechanic is taking them yesterday. Some time back, my buddy Matt recommended a place in Oklahoma that did awesome work on his injectors. Matt also told me that the place had told him some injector services use crap chemicals that destroy your injectors - they'll seem OK at first, but ultimately they are toast. More than I ever wanted to learn about injector services. So, I called that place in Oklahoma yesterday, and asked them whether their cleaning/testing process would be able to identify whether the injectors were toast or not. They said yes. Then I asked them if any reputable injector place would be able to do the same. They said they don't really study their competition, but they do know of a place in the NW that does excellent work, called the Injector Doctor, whom they do business with regularly because they are so good. Guess where our mechanic is taking our injectors? Then I posted all of that on here, and Mod immediately said he knows of them and they are very good.

EDIT: So, short of spending $1K on brand new injectors from the dealer, or finding someone who is selling the miraculous Bosch injectors brand new, I don't see how we'd be any better off than letting these guys assess ours and follow their recommendations from there.

 

Appreciate the good luck, but please, NO MORE STATING THE FUCKING OBVIOUS GUYS! Really, does anyone reading this thread think that it hasn't occurred to us by now that we should have made a different decision in the beginning? It's not helpful to point that out now. PLEASE STOP.

I'm on this forum to help others learn from our miserable path, and to seek advice from those that actually want to see us succeed. Not to be told what idiots we are.

 

Good to know that these guys are great. Hopefully the price will be acceptable. It is difficult to find brand new Bosch injectors for less than an arm and a leg for sure! Just hang in there! I think you are almost through it all.

 

I never called you an idiot... thanks for the shouting though. Glad to see how you treat people who wish you well. Go fly a kite. Unsubscribed.

 

Thanks Bama. I'm trying. Appreciate the kind words.

When you have the advantage of hindsight, everything looks different. We didn't have that when we chose this path. All the options in front of us included some level of risk and cost.

 

You're right, I'm sorry, you didn't. You are catching me at my very worst right now since this all started. I apologize - I took my frustration out on you and you didn't deserve it.

Sincerely, thank you for the well wishes.

I am just extremely sensitive right now to anyone criticizing our initial decision in any way. Hope you can understand that.

 

No, the injectors are between the pump and the FPR. This is why "no drop in pressure at max fuel demand" indicates sufficient flow.

See above.

OP, Hang in there. I think the second opinion on the injectors is a good plan. If it's any comfort, plenty of V6 Tacos with well beyond 200K are running on original injectors. In fact most are. I'm at around 240K and still get the same mileage and performance as new.
