I'm not sure if this is the place to post this but, I have a 78 CJ-7 wit a 304. Yesterday while driving back from the local car wash, I started to get a loud knock, if I let off the gas and let it idle the knock wasn't to bad but if I gave it any gas at all it got louder in relation to the RPMs. I am pretty sure it's a rod knocking (I could be wrong)and I am on a budget (cause uncle sam pays so well). I can turn a wrench and am willing and want to learn to be able to fix anything on my Jeep, I just don't know what would need to be changed out in order to get it back on the road. I can't afford a crate engine or to have someone rebuild mine. I can follow directions and get things done as I rebuilt the TH400 using a Haynes manual and rebuilt the Dana 18 using an online write-up and both work great. Any help would be greatly appreciated.
