Lets hear all those stories of how you tried or succeeded in Killing and engine on purpose . I personally tried to kill a 305 in a 87 Monte Carlo SS , for reasons I will not explain here , but anyways ........ I brought the car in the shop one day at 9:00 am , put it up on the hoist , drained all the oil (left the filter on)and then started the car . I looked at my boss and said 10 minutes thats all I give it , he said 20 idling . After about 30 minutes car was still running without a single rattle or anything so we started to rev it up some to speed up the process , nothing , over an hour into the process of reving the thing up to 3500 + still nothing , absolutely unbelievable ! Now the boss decides to take it for a drive , so he does and drives he crap out of it , now when he gets back to the shop its making a bit of noise , sounds like a few noisy lifters so we just leave it idle and I work on another car expecting to hear this thing get louder and louder but to my amazment its gets quiet again , I yell for the boss he can't believe it so he goes again and come back and says to me theres no way I got all the oil out and I say put it up and lets pull the plug again . Once the car is up in the air I pull the drain and about 3 drops come out , now we look at each other and start laughing because its been over 2 hours and it still runs and quietly too . Well its time to go for another drive again say the boss and he does , and he comes back with it rattling again but its just lifters , so he says just let it run , its gonna die sooner or later so we do .
After lunch the dam things still running with a bit of noise so the boss says go for a drive and I do , boy do I ever , I drove the living crap out of this thing , never took it out of 1st gear , gone for about 10 minutes , and I did it I made it knock , yehaaaaa ! I woulds have never belived it in a million years , but this is absolutely 100 % true I did it , seen it , lived it . After we had a definate rod knock we poured the oil back in and shut it off . The next day we started it back up and WOW the knock was 10 times as bad but it still ran .
Almost 5 full hours with no oil , amazing !
