I've got a 6nz problem.

As far as I know he did not try putting air to the cylinders. Its still apart so Ill let him know to do it.

He explained to me that the amount of fuel in the cylinders was more than usual.

Thanks for the response DDS.

 

Pull the exhaust manifold off look for traces of coolant out of each port.The cylinder head needs to be checked for cracks this is done in a hot tank with air pressure.

 

Thanks chopper


He will be pulling it off to replace the exhaust gaskets tomorrow. Will check for any signs of coolant. All the coolant I use has to be going somewhere.

 

When you had all the injectors out did you pressure up the coolant and bore scope each cylinder looking for water near the valve pockets? If no water in the oil or on the ground then my bet your burning it out the exhaust which means you have to pull the cylinder head to pressure check for cracks in a hot tank with the valves removed.

 

If the head is crack free check the liners for small pin holes. Liners are also pressure checked when out

 

Yes he checked all the cylinders with a scope, water pressure was over 10 pounds, and was sitting like that for 5 or six hours. No coolant was in the cylinders. I don't know about the valve pockets, but will ask him and see.

 

If you are pulling the exhaust, I would leave it off and plug the turbo oil suppy. Then install the injectors and Top end. That way you can start the engine cold to see what cylinder is wet,
If any after the broken injector is replaced
