3406e CAT issue/question

sounds like a blown head gasket to me i just went though the same thing new head gasket running fine now

 

You have one of three problems and all of them require removing the cylinder head

1 The head gasket is blown allowing coolant to enter the cylinder

2 The cylinder head is cracked allowing coolant to enter the cylinder

3 The liner flange has cracked allowing coolant to enter the cylinder

The white smoke you're seeing is the coolant being burnt. The reason the engine will not turn over now is the cylinder is full of coolant.........it's hydro-locked

 

Exactly what Mr.Haney said you got water getting into a cylinder....

 

White smoke at start up can also be caused by Fuel leakining past the lower injector O Ring and become most prominent at start up displaying large amounts of white smoke.

The Hydraulic lock can be caused by the fuel leaking down and sitting ontop of the piston. Depends on what position the engine stops at and what cylinder the injector has the faulty O Ring.

Leaving the engine sit for several hours and it will start as the fuel has leaked past the rings.

This can cause the engine to also miss- fire and also allow Compression Gas to enter the fuel rail which will also effect the way the engine runs. Aerates the Fuel in the Head Fuel Rail.

When replacing the O rings ensure you use/replace all 3 Seals on each injector and ensure that there is no reminence of the old tip seal left in the Injector Cup.

Usually a sign that you have a bad Injector O Ring is the engine wont start instantly and go straight to Idle RPM and smoke discolouration at start up.

Usually you will need to crank for a longer than normal time and when the engine does start it will hunt for a second or two before it finds its Idle RPM.

 

The reason Pro-Link shows No errors is its not an electrical fault so it all makes sense. I Think!!

 

if no coolant loss then like one post said bad injector or injector o-ring letting fuel leak by. careful you can score a liner or destroy a piston if its leaking that bad.

 

Mine was smoking white at start up then would stop after engine would warm up, it happen to be a mixture of coolant and fuel leaking into cylinder didn't start losing power until it became pretty bad.. I scored a piston, and cat shop in boise couldn't figure it out with their electronics
