big block fuel pump push-rod problem - 05/09/10 12:33 PM
Hey gang..
Wishing to tap into the collective... I have a friend with a '68 Charger R/T. He's been going through push-rods for the fuel pump like no body's business. He replaced the purple-shaft cam he had in it for nearly 15 years. After that, he's gone through two different cams, two different fuel pumps and about 5 different fuel pump push rods. All situations end the same, the push rod is damaged and worn down. When he replaces the push rod, he claims it moves freely in the guide hole. One local suggestion is the oil he's putting in now has no zinc in it. They suggest Royal Purple.
Personally, I've been changing my oil over the years and have never had a push rod problem. There are countless 440 running around and I don't see a rash of fuel pump push rod failures....
Thanks for any insight.
