Bent Valves Anyone know the cost on having a mechanic replace Valves on a 2000 Nubira?

Yes , your neon has a interference engine , it will bend valves , put holes in pistons .

Find another mechanic. you got ripped off. A broken crank does not mean you cant check the valves. Called a leak down test. This engine should have been replaced. And probably still should. Your talking about a $1500.00 job.

Are you replacing a broken timing belt? Or are you replacing a belt because it's due by miles? If the belt is broken, i strongly suggest inspecting for bent valves. Daewoo is notorious for bending all valves and breaking valve guides in the cylinder head when the timing belt breaks. The broken belt is also common.

Sounds like the Timing belt broke while the motor was running, the engine would have died when that happened unless you busted a cam shaft. if the Timing belt was broken and it happened while the motor was running there is a 90% probability that you bent every valve in the head assembly from contact with the pistons.

your Daewoo has an interference engine, when the timing belt brakes the valves hit the top of the pistons, and get bent. you will need to remove the cylinder head an replace the valves.....sorry.

hes right if it has an overhead cam motor

a couple bent valves shouldnt be more then a few hundred dollars to have replacedand can be fixed yes, but also the vehicle has to have another timing chain ooput on and be retimed this will probably be a total cost of somewhere in the $800 dollar range (this is only an estimate!!) to replace your entire engine would cost substantially more and in all realit i would try to sell the opother vehicle for parts, trade in, or as a whole and buy another vehicle before i invested the money into a new engine for this particular car

it is the heater core it is located behind the dash im a certified mechanic and have replaced many of these

yes it is possible for the valves to get bent depending on how long it was ran after the belt broke

who didnt rotate engine 360 by hand before starting ,bet valves bent
