Allroad problems

[SoGoneSoFast]

Went to start her up and she sounds like a diesel and puked out all the coolent where do i start any ideas would be of great help.

03 140k miles oil changed a month ago, timing belt accessory belt water pump belt tensioner spark plugs and coil packs all replaced about a year ago all work done myself.

Some more info please, any work done recently? Or did you just go to start it as normal one day and it started having all these issues? Can you not see where the coolant is coming from? Or has it been sitting for that year when you did the timing belt?

Make sure your battery is good and has full charge. Clear the codes and start over because low voltage will make a lot of stuff throw codes.

Its my daily driver occasional misfire. The coolent looks to be leaking from the front of the engine haven't started digging in too deep yet. Battery 12.15v clean terminals.

[PaperToast]

coolant leak could be from the thermostat housing
the plastic ones crack with age and time

[SoGoneSoFast]

I did replace that also but i agree that might be the source of the leak i am more worried about the rough sound the engine is making and all the misfires.

[PaperToast]

misfires could mean either something other than fuel is in the combustion chamber (oil, coolant, wrong fuel/air ratio), bad coil packs, or oil/coolant in the spark plug wells

[4rings2turbos]

I'd say something went wrong with tensioner pads or failed tensioner on bank 1 causing chain rattle but it's odd that 4 and 5 on the other side are missing.


Start by clearing codes and seeing what comes back. The diesel sounds, plus misfires, plus implausible cam signal makes me think timing is off inside the heads.

[SoGoneSoFast]

Going to get snake camera to check pistons for any contact then i'll top coolent off clear codes and fire it up. Thanks for the help will be back with updates.

[4rings2turbos]

Your well equipped!

Good luck

[SoGoneSoFast]

Bad news 1,2,3 have made contact so i won't be firing it up need to pull the head a check how bad it is hoping not too bad. Is it possible to do this without pulling the engine?

[SoGoneSoFast]

Would a compression test tell me anything before i remove the head?

[tewnick]

I would remove all your spark plugs and turn the engine over by hand slowly and see if you have any interference before doing a compression test. Maybe do a leak down test after turning the engine over by hand and before the compression test.

Good luck. I just got done replacing my engine because the idler pully went bad allowing the engine to skip timing.

Your well equipped!

Good luck

Ew, *you're.

That's a real bummer my friend, sorry to hear that.
