ok I got a 73 455 in a 69 firebird and I was drivin down the road and heard some bad noises... lost ALOT of power and my oil turned grey... I know your thinkin antifreeze in my oil but from where? I think the timing chain slipped could that have knicked the side of a water jacket?
Too many possibilities ... a blown head gasket could have this effect - but knowing what the noises actually were would help, too. Combustion pressure in the water jacket will sound like a snall pistol being shot in a well. (OK ... I tried! )
"Slipped" timing chain is not likely. Cracked head or block would more than likely have drained the water and overheated the engine. I'll put my wager on head gasket. What color was the exhaust smoke? White? Or black?
yeah, the timing must have jumped becuase the timing is way off... there was no abnormal smoke thats why I dont think it was a head gasket or anything.. uhh when I got home I notice a lot of leaking oil comin out, looked at the car and all the oil had shot out from underneath the waterpump, all over the harmonic balancer thing all over the lower radiator hose and the sterring linkages... nothing on top so it had to come from down there almost like something popped with pressure it was kinda sprayed out, the car starts... doesnt idle.. backfires up through the carb sometimes when I try to start. anymore suggestions please help me!!
Don't start it any more. Get the timing chain cover off and figure out what happened. The bottom of the timing chain cover opens up into the oil pan, so that might be where the oil is coming from. Also, the timing chain cover and water pump share a common wall. If you somehow blew out the water pump ...
It's impossible to try to fully diagnose the problem this way.
Ok... I pull of the water pump and to my suprise/releife the common wall bettween the water pump and the timing cover was destroyed. found my problem thanx for the help
Anytime. I'm kinda laughing that I was right. I never would have guessed that from your first post.
Be careful when you put it all back together. You have now got water in all your oil passages. When you chnage the oil, remove the distributor and turn the oilk pump drive rod with a drill. (You'll need to cut off a screw driver with a long enough bit to reach down in there.) Push a bunch of oil thru the engine first, before you fire it up. You might even want to drain the oil after running the pump to get out any residual water.
