I recently purchased my 1992 Plymouth Grand Voyager with 189,000 miles. This vehicle was extremely abused and had a very noisy lifters and valve train. I blew a head gasket two weeks after I bought it and during the tear down to fix the head gasket I noticed severe wear on the lifter bores and the lifters themselves. Instead of buying $120 dollars worth of lifters for a van with 189,000 miles on it I decided to give LUCAS a try. WOW!! The van runs smooth and the lifter noise is completely gone! I saved $120 bucks and got the same results by using your product.
