Hi all, I have sent them a detailed email of what has occurred. all is below Dear Richard, As you know I purchased a Toyota Corolla T Sport reg - RV53CZT on 9th August 2012 for £2800, which included a 3 month warranty. on the 5th September I encountered a loud knocking sound from within the engine, I called Thompsons garage and was advised to get the car towed to your site, which I did. After looking at the problem you decided to change the engine, I picked up the car ( 20th September ) having the understanding the car had been fixed. I drove the car 17 miles before deciding to see how the car would drive when in higher Revs. There is supposed to be a lift at 6200 rpm but I encountered no lift and instead had three warning lights come on the dash - Engine management, TRC OFF, VSC I called Thompsons again and was told to bring the car straight back, which I did. It was mentioned that it is not good for the car to be revved high however when researching the problem I found the below info about revving the car at the 6200 rpm . ( extracts from the SAE paper on the development of the 2ZZ-GE ) At engine speeds below 6000rpm, the rocker arm moves according to the low lift roller follower. When engine speed is above 6000rpm, hydraulic pressure is applied to the locking pin, which slides under and locks the high lift slipper follower to the rocker arm. This creates the difference in valve lift, for the rocker arm will now move according to the high lift slipper. When engine speed is below 6000rpm, the return spring pushes the locking pin back, and the high lift slipper is freed. Max Power 135kw/7600rpm Max Torque 180Nm/6800rpm I have been told I will get a further 3 months warranty when the car is fixed and back to full working order, the way it was when first purchased. Please can you confirm this is the case. Can you please guarantee me the car will be the way it was when I first purchased it on the 9th August 2012 . I have only had the car for 3.5 weeks of the 7 weeks of owning the car. I await your response. Regards Roshan Mawar they have replied with: Hi Toyota have said timing pin stuck.
