Review on Engine Tensioner Sprocket 12680750 Pontiac by Alex Jain

I will not buy again. The upper timing chain guide does not fit. I had to buy in the Autozone. After I installed everything there was a timing noise, I had to open everything again, found that the hydraulic timing chain tensioner failed and the chain was loose. The engine was nearly damaged. Very bad cheap stuff. I bought 3 and this will be the last time I buy this from you.
