Overheating 351 w it is blowing water out of the rad and and tailpipe?

Question

I have a 351w in a 87 crown vic that i use as a enduro race car it blew up the rad ( Compleatly blew the tanks of it ) Replaced the rad put a new fan on it ( was shue the fan was why it overheated ) started next race and all apperd to be ok untill the temp suddely peged we pulled of the track coold it off refilled the rad and went back out it was ok for a few laps but it peged again and started to pump water out the tailpipe was told that we blew a headgasket or cracked a head any way to cheque without sending the head out

thanks to those who replyed there is no water in the oil and no oil on the rad. in the class of racing that i do i have to stick to stock heads

also there is no thermostat only a large washer type divice to restrict waterflow

Answer 1

Most likely as the others have said, it is either the head gasket or heads. I have had a problem where it was the intake manifold gasket and it was spewing water out of the carburetor like a gusher. When I shut the engine off, I had water in a couple of cylinders.

Answer 2

remove all the spark plugs preausreize the rad and watch what spark plug hole has water comming from it You may have to turn the enigine remove that head have it checked for cracks an replace gasket install a new thermostat an go to a racing supply store an gat a racing rad cap higher preasure will help also

Answer 3

your blew the headgasket.the only way to check them is to take them off and have the heads resurfaced or you can get some other heads put on . the 302 heads will fit the 351 perfectly. water out the tailpipe is a dead giveaway of blown head gaskets

Answer 4

there are a few way
1 compression check the cyl.
2 pressure test the rad.
3 pulled the heads

Answer 5

The thermostat likely froze up that caused the problem. When the head gasket blows water will mix with oil and under the oil fill cap it will turn milky white if its blown. Good Luck and GOD Bless

Answer 6

Your SOL bud unless you plan on new heads they should be checked out by a machinest, especially if they are aluminium. besides haveing them magna-fluxed you will want to make sure they are not warped. But look at it this way now you have a good excuse to upgrade your heads. I recomend the ford GT-40 head inexpensive yet good flow.

Answer 7

sounds like a blown head gasket or cracked head for sure. when you dismantle the engine pay close attention to the head gasket you usually can see where it is blown even still you should have the head magnafluxed to check for cracks

Answer 8

yes you can get a radator pressure tester and pressurrize the system if it has blown head gasket your hear it coming out the tailpipe or it bubble the water in the rad
