I noticed some coolant leaking from what I thought was from the weep hole on my water pump but after further investigation we have found some coolant leaking from under the intake manifold. We recently installed a Buschur stage 3 head and used a stock head gasket with arp headstuds torqued to 95ft lbs like Buschur reccommends for their head. After the car was tuned is when I started noticing the leak. I have no signs of a headgasket leak at all. No oil to water mix or vise versa. Also I am not burning antifreeze either. My friend things there are some freeze plugs back there that could be leaking. Is that what it could be or what else could be the cause of it on the back of the block?

 

Definately sounds like a core plug issue. If this is determined the cause, Permatex #1 can be used around the core plugs and put back in, problem solved

 

Try checking the hose that goes from the block to the throttle body. Mine broke and all the coolant leaked out. I thought it was the head gasket too at first. Hopefully yours is a simple fix like this.

 

 

i think i have the same problem but i see some anitfreeze on the front of the motor rite on the head gasket

does anybody have pictures of these core plugs and where there located
