well i bought my new project car for cheap and there was a crack in the radiader so i drove it home and with no water in it, it drove good but over heated a bit... well i get home fix the radiader and put whatever in it start it up and after a sec the car runs like crap.. drain the water out and it runs good.... headergasket or something else? doesnt smoke just in high wot im running oper header and it does blow out a tiny bit of water after i rev it really high.. is this a head gasket or could it be somethign else thats cloged maybe??

 

when you fill up the rad you gotta bleed the cooling system to get rid of any air bubbles that are in it.

 

how do you do that? buy taking off the lid and letting it run right??

 

Do you see white smoke when the car is running with coolant?

Does your coolent reservoir have clean coolant in it or is it oiley?

Look at you oil. Does it look foamy?

 

ive just been runing water but when i rev it up it does smoke white a tiny bit but it also is open header.. oil looks good im bleeding the coolent system right now ill update soon...

 

I think your probably wasting your time bleeding the cooling system. If your getting any white smoke, your head gasket's gone and the only way to fix is to pull it apart and replace it. You should check the block deck and the head, very carefully, to make sure they aren't warped, before you put anything back together.
