it just started up a couple days ago and i've only driven it 3 miles since then. so there shouldnt be any horrible damage. i'd rather put the time and money for one piston than not having a car before bootcamp.

Assuming you can get the oil pan and the head off then you should be able to replace the connecting rod without pulling the engine. Its just a matter of turning the crankshaft into the proper position to get the bolts off the back of rod and then turning it some more to move it into a position where the piston can be pulled out the top. Put rubber hoses over the connecting rod bolts so you dont scratch the crap out of the cylinder wall!!

Ok some of the answers are sorta good. Maybe. Anyway, more than likely it is a rod bearing knock. It can be difficult to determine a bearing knock from a wristpin knock. But in any case if you are replacing the bearings the best way to do it is to get a crank kit. It comes with a new crank and bearings REPLACE THEM ALL. The connecting rod itself should be fine. No need to pull the head. The best way to do this is to pull the motor out and turn it upside down get a repair manual so you can get the torque specs. Make sure you put the bearing caps back on facing the direction they came off and back on the same rod.

If its a rod knock then the bearing where the rod and crank coneccts is gone and usally now the crank is of balance too. So if I were you I would take the crank to the nearest engine rebuilding shop to get it checked to see if the crank can be balanced out or can be micro polished. If not you would need to get another crank. Second is why replace that one only, you would only have to go back in a few months and replace another. So replace all four while you still have it apart. Just make sure to get the right parts and some lube. Other then that you should be okay

It can be replaced but your not replacing the rod your replacing the bearing that goes between the rod cap and the crankshaft make sure you lube the new bearing with prelube before you put it back together.

all the answers before mine are great..But the main thing about a rod making noise is the fact that the rod bearing is bad and 9 times out of 10 the cranks bad too..but it should last tell you haft to go..
