Well nether mechanics are friends of mine. the first was toyota of Ukiah,ca
they stated that in my case the injector was going out due too coolant.
And they went on to say that they could take the heads off and check them and that most likely it would be hairline cracks around where the valves are.
they said be prepared for the worst case scenerio.
1. just worn gasket
2. cracked head
3. cracked head and do examination of cylinders and find bad scoring etc.
so that was Toyota.
So I mentioned this to a few friends and they said I should get second opinion and that is how I learned of the Yodaman (larry) he is in all the 4x4 mags and has impressive yodas and many nice yodas he was working on.
So made appointment with him.
And he said the same thing as the toyota dealership and did the leak down test.
Leak down test 100.00 done.
#3 cylinder 64% 4,5 and 6 around 27 to 36%.
a good cylinder is 19%
toyota 3200.00 for new head install
Larry the yoda dude: 3000.00 head install have of these estimates are labor.
and both said they would only do the work if the cylinders checked out and bearings of bottom end.
see that is the thing when these mechanics tear it down they are unsure of what is up until further testing. So no telling what they will find but both said that most likely one would need new heads.
neither would even install manufactured heads either.
I have yet a third mechanic next to my home that will take yet a third look monday or tuesday. this mechanic will be most likley to tear it down.
btw, out this way the cheapest quote I got for rebuild engine and install was 5k.
your don't disagreeing with me you are disagreeing with them.
I was just passing along what I learned from these mechanics.
Gawd I only hope it is the gaskets. I would be so frekin happy.
