So the exhaust valves have touched the pistons. But isnt the failed valve an inlet valve. Link to comment Share on other sites More sharing options...

I am no legal person but would think you could take it to what is/used to be the Small claims Tribunual for amounts less than $10K and you can represent yourself.The problem is if you go with lawyers they will just bleed you and you could spend more time and money than what its worth.

Member 3,343 Member For: 17y 8m 17d Gender: Male Location: Canning Vale, W.A Posted 15/08/13 12:00 AM Share Posted 15/08/13 12:00 AM No disrespect inteneded to some of the other people on here, but I'm 100% with ratter on this one, when an engine is built the valves are seated to form a SEAL on the head, if like has been stated the valves were bent in the past it would be very noticeable, generally when a valve hits a piston it will generally break a bit off the head of the valve or else bend the shaft not allowing the valve to retract properly and then causing it to break the head off, this wouldn't happen years later, it would happen minutes later. Also regarding cars jumping teeth, it was my car that jumped 2 teeth and sounded absolutely horrible!! but in my opinion also it is exactly what was stated that causes it, sudden jumping off of the throttle, when mine did it, I had just came out of around about and accelerated in second then made alast minute decision to get red rooster and jumped off the throttle quickly at around 4000rpm. so the theory is, that the sudden jump makes the tensioner retract back but it still has quiet a bit of mechanical force on the engine then bam jumped teeth. Is there a fix? I honestly don't think so, just driving style I think, until someone releases a slightly stronger tensioner (which could cause it's own issues) my chain guide didn't really have any big chunks out of it, but it was a case of better safe than sorry. So there is my rant, so in the opinion of 2 qualified mechanics saying it wasn't due to the timing issue it's not looking great sorry to say Did the exact same thing, turned out of a T junction, gave her some stick. Noticed the set of lights had a camera and jumped the brake at high revs. Lets just say a possible 350$ fine turned into a 4.8k engine recondition.

How many pistons show impact damage of the inlet valves Link to comment Share on other sites More sharing options...

blueprintbullet Donating Members 163 Member For: 16y 9m 12d Gender: Male Location: Wanneroo Posted 16/08/13 01:33 PM Author Share Posted 16/08/13 01:33 PM Today the vehicle has been taken to the Engine Exchange for a thorough report as to what has caused the engine failure, they will be checking the valves for leakdown with a vacume tester and will also measure how bent the valves actually are. I also recieved the history from Nuford stating that when the timing chain guide failed it was two teeth out and displaying two codes P1381 and P1386 very similar to the thread titled "Serious metal to metal noise". Nuford are predictably burying there head in the sand hoping I will go away, but I can afford to loose and will personally not back down as I feel so strongly about this. 1 Link to comment Share on other sites More sharing options...
