Help with a 98 tacoma with a 2.7

If the EGR was not working properly, I'm pretty sure you would be getting an EGR-related code.
I would look at that last.

Do a compression check. No cost to you, if you have a checker already or can borrow one.
190 psi - very good
150 psi - good
120 psi - barely acceptable

 

So if compression is bad the. Head gaskets would have to be done again?

 

If compression is bed then do a leak test, at that point you must determine whether you need a new head, a new set of rings (more than likely Pistons to) or a new motor all together....

 

Guess we never asked how many miles

 

Sorry I just missed your post. It has 177k on it. Everything is original.

 

Test cool ohms and get back to us, if you can do the compression test ASAP, if those both check out, pull the trigger on the egr

 

Ok will start putting everything back together to test the coils and compression. i really hope at least compression is good. coils wouldn't be the end of the world just a bit $, but compression would be a different story. I have my fingers crossed for either egr or coils.
How accurate is the hand testing method of testing the coils like removing it while vehicle is running to check for rpm drops?

 

HELP!!! I was getting ready to put fuel injectors back in to do a compression test, and one of the spacers broke into a million pieces and fell below and past the piston and into the combustion chamber. I tried using a wand attachment to my small detailing shopvac that could fit in there but nothing.
Does this mean I am going to have to take the head off and clean those out??

 

You mean it fell past the intake valve? You could try using some compressed air out of a long attachment and blow it out through the spark plug tube, but if the plastic was that brittle I think it would just disintegrate when you start the engine.

A machine shop told me those plastic spacers always break apart when you try to take them out. I guess you should turn the engine so those intake valves are closed in case the spacer breaks apart.

 

Yeah I never thought of turning the engine before doing that. I am going to do that for sure before doing the others.

I cannot for the life of me get the other ones out. I am afraid they are going to break as well, but they need replaced for sure.
They are brittle and one even has engine oil in it, and looks like it was soaked in it.

Maybe hold the vacuum by it as you try to pull it out or break it apart to get it out. And I assume you have the 2 o-rings (one behind the spacer) and grommet for the injectors?

 

The injectors were fully removed, so its just the plastic cup spacer thing. It may have had an o-ring in though I am not 100% sure.

 

From a 96, 2.4L. The parts are listed in order at the top of this picture. Should be the same or similar to a 98, but not 100% sure. There is an insulator in addition to the grommet and 2 o-rings. And a light coat of gasoline to lubricate during installation.

 

I will go look in one second and see how many o-rings I still have. Hopefully all of them.
Is the o-ring going to be an issue if it did fall in there with the plastic?

 

I would not think it would be a problem if it fell in, just want to make sure you have all the parts. These o-rings shouldn't be reused. I'd bet the big o-rings that go behind the spacers will just crumble apart with the spacers.

 

I should get a new o ring kit then. The new spacers came with them already in it. Would just any o-ring kit work for the smaller rings, or would it be special order?

thanks

I do not mean switch from original subject with this fuel injector issue, but one last question on the fuel injector spacers.

Does anyone know how to remove them without breaking them more?

I need to finish removing those so i can get the injectors back on and do a compression check for the engine.

thanks

JP

 

If you already have the bigger o-ring that fits between the spacer and cylinder head, then this set looks like it has the other 3 parts (small o-ring, grommet and insulator).

You could probably find other sellers of similar kits. The parts look to be pretty standard across many Toyota models and years.

If you wanted Toyota parts it would be a little more expensive. (12.34 per injector, if I added correctly)

I finally got all of the old spacers out. It was a major battle, but got them out without anymore plastic falling into the head. However when i finished getting the first one out I saw that it had a crack or a slice hard to tell in the middle of it.

It Doesn't look huge but would it cause any issues. I would think the new cup would just slide right over it but wanted to see what you guys think. Also going to order new o-rings tomorrow just want to be safe and not re use old ones and cause the issue not to be fixed.
The pics are both of the same injector hole. I just tried to get a close up.

Thanks all.

I'd try to clean the holes up a bit. Maybe you already did. It's hard to tell from the pictures. A minor imperfection shouldn't matter because the rubber o-ring between the metal and spacer should prevent any air leak, but you could judge better than me once you get the parts and see where the o-ring will sit in the opening.
