2006 Chevy Trailblazer

Asked by mr_mrs_cook Sep 02, 2013 at 07:00 PM about the Chevrolet Trailblazer

Question type: Maintenance & Repair

Our Trailblazer died on the interstate going 75 mph without any warning lights.  Everything lit up and it just died.  We got over to the side and tried to start it back up.  It acted like it wanted to start.  It would turn over but never start.  After letting it sit for about 20 minutes it started but I had to keep my foot on the gas.  I drove it for about 3 miles while the oil pressure gauge would go up and down.  I got off at the next exit and the motor was hammering and I shut it down.  We tried to start it to move it onto a trailer and it wouldn't even turn over.  Any ideas what is wrong and how much it may cost to fix it?

,,,Well you never said what year this engine is, but if you had been listening to the motor should have begun to sound like a can of marbles, as the timing chain has apparently jumped a tooth...this a chevy 350 engine? have a mechanic take the timing cover off and inspect the looseness of the chain and position of the sprockets~ Depends on the level of the destruction to the engine to set a price~....gonna be LESS than a rebuilt engine to fix~

the "hammering" part is a bit disconcerting...I've lost a chevy 400...the connecting rod broke and pierced the oil pan...motor toast...welded the pan back and put it onto another rebuilt~

The key clue is the oil gauge fluctuating. You ran low on oil. Engine likely toast.
