Thanks GTP dad. I have one concern on the replacement of the lifters. I am not a mechanic, but know a little about cars. How can I be sure it is the lifters that are bad. When I start the car it has a very loud tapping noise and has gotten worse over the months. It started the end of last year, but only did it for about 3 weeks then quit. It just started making this noise again about a month ago. My neighbor, who has his own shop, heard the noise and wanted to be there when I cold started the car the next morning. He was there the next morning and listened when I started the car. He told me I had several lifters that were bad and that I may as well replace all of them while they had the engine apart. My concern is, how can I be sure it is the lifters. I would hate to spend all this money on parts and labor only to find out it is not the lifters. Is there a possibility it could be something else? The only reason I ask is that I have been ripped off by other mechanics and do not have a lot of trust in them. Once again any advice will be greatly appreciated.
