Brain box failing

The timing belt cut and bent the valve, after changing the inlet valves, we started the engine and fired it after some minute the ignition off and stop working. We replaced the brain box with another it started after some minutes again it stop and did not start agin. What could be the problem? The engine or what could be damaging the brain box?

SOURCE: Timing Belt and Intake and Exhaust Valves..

At least engine head must be removed for inspection and repair. When head removed you can estimate also if any damage on pistons top surface.

FIRST!. Get a proper/professional diagnosis of the CAUSE of the problem. If the cause is related to the work done by your mechanic, then take it back to the mechanic and tell him to fix it! Otherwise, take the veh to a Hyundai Dealership, get a diagnosis and estimate of repairs, hire a lawyer and sew the mechanic/garage that screwed it up.

SOURCE: Is it adviceable to ring the engine or replace the engine?

If it is a high mileage engine I would say not advisable. Why would you replace the rings? Low compression? Oil Burning?

Testimonial: "Thanks for the response. Oil burning. The car is just 5years, the milage is about 75km"

Changed the water pump and I had to reset timing like 15 times took it apart and checked and would not fire up. Finally checked again today and it was out. I got it all timed in and rotated it a few

if you bent valves then there will be insufficient compression to fire the mixture. have a compression test done to determine if the valves are bent

What happens if car doesn't start after changing timing belt with a mazda protege 1999

If you did not have the bent valves replace then that may be the problem. If the belt has not broken then turning the engine over with the belt removed will bend valves. I suggest that you have a compression test done to eliminate the valve problem. Next is to recheck the cam shaft timing . next is to check the position and firing order of the distributor.

Car not firing

Most likely the valves were bent.
When you attempt to start the motor does it turns over a bit fast and will not sound quit right - Not even attempt to spark up or fire up.
Check engine cylinder compression. The valves were bent when the belt broke.
you will
1. check compression (and when it fails)
2. decide to have the head checked and if possible rebuilt (use new head bolts)
or
3. Look for and buy a low milage used motor
or
4. Look for a rebuilt head

Compression test on 2000 dodge 2.4l

Most probably... All these modern DOHC engines have interference designs that play havoc when belt fails... valves can collide with piston or between them too. To check without opening engine, you could remove timing belt cover and timing belt, and carefully rotate one cam to feel if it binds or not. But engine starting points to a jumped tooth on belt reinstallation (bent valves would not even allow engine to restart! Amclaussen.

Timing belt broke, replaced it and double checked that the timing marks were perfect, engine light comes on after 15 minutes then stalls all the time. the parking lights come on periodicaly when car is...

If the timing belt broke when the engine was running, I would say that you may have bent some valves. If I remember correctly, Chrysler engines stopped being the 'free-wheeling' type after the Acclaim.That is, there is sufficent clearance between valves and pistons to ensure no damage should the cam belt break with the engine running.

As you have had the engine running, it would be a good idea to give it a compression / leak-down test. Unfortunately fuel injected cars do not back-fire through the intake system as a carb type would do, if a valve were bent.

Timing belt snapped

hi from uk the cambelt timing marks for accent 1.3/1.5 petrol are as follows= the cam cog has a hole drilling between the outer toothed and the central securing bolt this hole at TDC number 1 cyl is at top central and lines up with a V cut in the cyl head at rear of cog ? the crank cog at TDC number 1 cyl is a pop mark on both the cog and on thefront face of engine quite noticable ! these line up and are at approx 12 -30 pm when viewed fit new belt from crankcog in anticlockwise ie crank then cam then tensioner HOWEVER! if you are considering just replacing belt and tensioner ? be warned this engine is an interferance engine that is to say if belt fails whilst driving there may/will most probably be damage to the valves (bent) due to contact with pistons so would advise caution and suggest compression test all cyls after fitting new belt and tensioner and before rebuild completely once valves have bent they will not contact pistons again but you will have serious missfire/s and probably back fire up inlet manifold coupled with failing to start if engine is high milage ? consider removal of cyl head and check? de coke and replace damaged or best all valves then engine will have improved performance and more milesin future hope this helps

Change my timing belt valves got bent shop said was carbon

nO! dont get scammed they messed up and had the timing off and it fired your valves off at the wrong time and bent them dont take it to anyone else ...take it to the manufactures and let them know what happened and i would get in touch with the BBB.... see your timing belt turns your camshaft which turns your pistons up and down now if you timing is off your piston will go up at the wrong time and force all that combustion back at your valves which are made up of light metal and then they bend .....call the garage you went to and let them know that it was there fault and you want it fixed ......this really makes me mad being an mechanic myself. I hope this helps you a little.

Bent valves 2000 Ford Escort ZX2

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

Engine shut off, not getting any fire.

usually if no plugs are firing it would be a crank sensor but in the cam area you have a timing belt that keeps the timing between the crank and the cam if that has broken or stripped then it will not start and may have done some extensive damage to the engine.

Daewoo lanos not starting after renewing water pump

YOU DON'T HAVE THE TIMING CORRECT AT ALL. YOU DON'T HAVE IT TIMED RIGHT ON THE ENGINE. IF YOU KEEP TRYING TO START IT AND RUN IT, YOUR GOING TO CAUSE SEVERE VALVE DAMAGE TO YOUR ENGINE ... BENT VALVES. TAKE IT TO A SHOP AND HAVE THEM FIX THE PROBLEM BEFORE YOU MAKE IT WORSE.
