engine life?
 

how long does the average big block nitro engine last?

Depends on what you do with it and how abusive you are. They can last from a few minutes to several gallons of fuel. On the average, about 5 to 6 gallons.

thanx

once your engine life runs out do you have to replace the whole engine or just replace it? (used to car engines where you just rebuild)

you can just do a piston sleeve rebuild. very easy. :D

If you tune your motor correctly and keep it clean (outside & inside), they can last much longer. It is more likley you will wear out the rod or a bearing before a piston & sleeve. It also depends on the quality of engine (& fuel) you start with. I have many old RB's and I have only bought 1 piston/sleeve set ever (lost aircleaner). I have bought a few rods & more front bearings than anything else. I run my cars at least 3 out of 4 weekends year round and have WAY more than 10 gallons thru each of the 4 motors I currently run (all RB's). My newest motor is more than 2 years old.

ok i just didnt know. i didnt want to have to buy a new motor every season

if you are on a budget, when the piston and sleeve wears out you can get them pinched and you should be able to get another 3 gallons out of them and it only cost $20.
