Hi there, I Am Cam. Can I get your first name please?

Have you run the engine yet or are you just assembling the engine?

I have done this 3 times and they wont get any pressure at all
Expert:  Gm Tech (Cam) replied 1 year ago.

Jay, what brand of chains and tensioners did you install?

Did you have any troubles seating the tensioners then pushing it in to release them?

Also what is your oil pressure?

Customer: replied 1 year ago.
my oil pressure was fine! I did not have to replace them I just did it for safety on the future! I did not have any problems setting thet tensioners or the timing chains at all! the car is on time and cranks right up and accelerate like it suppose to do it but the noise is there from the tensioners not putting any pressure to the chains! I used advance auto parts and the brand was craziest or s.a .gear

I mean carquest s.a. gear sorry

OK, I have run into this before with aftermarket timing parts. Either the chains slightly too long, loose or tensioners. I hate to say it but either the release pins is still in the tensioner or they or the chains are bad. Your going to need to get back in there and put Ac Delco ones in there or even the original ones. There is nothing wrong with reusing them. Only the chains were prone to failures.
