while driving home after work cruizing on the highway around 65mph i go to pass some one and get on it a little bit but not enough to see full boost just held it around 13-15psi and all of a sudden i hear a loud pop. next thing i know i see white smoke coming from everywhere and instantly i shut the car off and coast to a stop. looking under the hood notice coolent everywhere so i tow it so my shop. Finding the source of the problem under the timing cover and also discovering that my timing belt is broke and bend some valves well what i noticed is this plug is missing or blown out why would this happen and what caused this????


sorry for the ****y cell phone picture but its the plug in the middle under the cam gears

 

Bad luck.

 

The stars were in perfect alignment.

 

lil motor info.... 2.3 stroker with p&p head 1mm over size valves with hks 272 cams

 

That a missing freeze plug?

 

thats what i figured it was but not 100% sure what should i do to fix it and to make sure it doesnt happen again?

 

Temps where normal? Sounds like the brass plug was not pressed in properly and finally let go.

I've heard of a few guys having problems with the freeze plugs on the block, never the head.

 

yes temps were normal and everything was just as it should be

 

do i just take it to a machine shop and have another one pressed in?

 

you probably blew your HG and pressurized the coolant passages, and when the freeze plug popped out it broke your timing belt.

that sucks, im sorry to see that

 

head gaskets is good and i have arp's so im pretty sure the head didnt lift and shouldnt at that boost level

 

weird, did you change your coolant recently?

 

Don't know where you are located but if there was more water than antifreeze in it and it froze, it could have loosened that plug up and was just on the edge of letting loose.
Otherwise, if your headgasket was fine, it was just bad luck.

 

to be honest yea.... about 2-3 weeks ago i just replaced the head gasket so ya i had to refill the coolent
