Tragedy on Cross Country Trip Home (1 Viewer)

I would guess head gasket and or head damage. White puffs were coolant traveling through a cylinder and out the tailpipe. After you stopped the truck, the coolant level in the head gravity fed down towards the earth and seeped into the cylinder with a piston in low position and keeps the truck from turning over (hydrolock). None of that is a big deal. Pull the spark plugs and look at them. Then turn the motor over with no plugs in and see what comes out the spark plug holes (disconnect the top center wire from dizzy to stop any spark from happening).

Also, drain the oil into a pan and see if you have coolant in the oil.

All of that would be work required prior to taking the head off to complete the repair. If the head is damaged, you won't know until it is off. If the block is damaged, you won't know until the head is off. All of that can be done with the engine in the truck. I wouldn't pay a LandCruiser shop more than 3 or 4 hours to have the head entirely removed and troubleshooting complete.

Good luck!

Not sure I'm actually turning anything over with the spark plugs unattached. I labeled each wire from the distributor, then unplugged them and ratcheted out each spark plug. With everything detached including the center wire from the distributor, I went to crank the car. A little help here? Pardon my ignorance.

Ok now realize I've got to turn the crank by hand. This is all new to me.

Tommy ,

- do u have a TAN 2F ENGINE FSM ?

- Do u have a compression tester kit ?

- Do u have a simple BORE scope like RYOBI or Milwaukee one from HOME DEPOT ?

 

[pumbaatx]

- The engine FSM is in Dropbox somewhere
- I can rent a compression tester from an auto parts store
- I do not, might be able to rent this too?

Autozone or O Reilly’s has specialty tools you can borrow.

 

[pumbaatx]

Do I need something special to turn the crank by hand? That bolt is giant.

What’s happening if you turn the key? Does the engine turn over?

There’s some other issues I see - no vacuum to the distributor cap, possible seeping oil gallery plug on the head and a bunch of other little details.

 

[pumbaatx]

Not turning over as far as I can tell

 

[FJACS]

Bolt on the crank pulley is 46mm. But with the spark plugs out, you can roll it over using the alternator pulley nut. Just don’t gorilla it.

I can’t tell if there’s no audio on the video you posted or just no sound coming from the truck. Seized or not, you should at least be hearing the starter click when you turn the key to the start position. If you aren’t, you either need to charge the battery or make sure the connections on the battery, the fusable links and starter connections are clean and tight

turn the motor over means spinning the motor. Not starting or running. Just turn the key and the battery will send juice thru the ignition to the starter which will turn the flywheel and spin the motor. Have someone watch for fluids coming out of the plug holes. Don't worry your truck is not going to start with the spark plugs removed but it should turn over unless you have a bad battery or wiring problem. No need to turn by hand.

Here is the video with sound not sure why the default on Imgur is to have it off.

Your Next step should be DRY COLD Compression test on ALL 6 cylinders

follow the FSM 2F tan manual step by step instructions


Most internal failures can be diagnosed this way , such as a blown head gasket

or a bad rings or piston etc ............


your engine cranking sounds sorta Normal ?


DO NOT PUMP your gas while doing these tests , especially with a WEBBER

you will fill your oil with RAW gas .........

bad bad ......

 

[g-man]

sounds like starter is not engaging the flywheel. Pull the cover off the bottom of the bellhousing (6) 12mm bolts and see if the flywheel is turning when the starter motor is running. If it's still not spinning the flywheel take a rag and grab the flywheel and with the transmission in neutral turn the flywheel by hand. You should make sure the flywheel is spinning before any compression test can be done.

 

[ToyotaMatt]

- ignore warm up engine

- preform test on all 6 cyl.

- record results on paper

- you specs cold should be slightly less then warm


- please post your results , starting from #1 cylinder ( front of engine )

- oh , make sure your battery is fully charged too

- hold gas peddle to floor to open throttle each tast

- NO PUMPING


- let see what this Diagnoses step yields ?

 

[ToyotaMatt]

but , yes your starter is Not engaging ?

is your Battery FULLY Charged ?

this is mission critical its fully charged
