I redid my 93 Burb heads (5.7 TBI) Sep 01.... the head gaskets were leaking....

I replaced the cam, lifters, pushrods, rockers, springs, the whole can of worms and all was fine....but it still ran hot... found the radiator to be clogged after a while and replaced it..... no problems at all so I thought....

It did get to 250 for a short time but that was it... with the old rad in it ...AFTER all the replacement stuff...

now I find the head gaskets are leaking again and at a dramatic rate!!!! I lose almost 1/2 gallon of coolant in 300 miles!!! It does not run hot at all and no oil in water and no water in the oil... it's seeping out the block at the gaskets.... both side are showing runn-off down the block.

No loss of power is evident and all seems fine except for the leaks in the gaskets.....

I fear that with the rebuild of the top end and running the clogged radiator that it built up too much pressure and heat to blow the gaskets... is this a safe bet?

Now... am I safe to just replace the head gaskets and not worry about the heads or should I have them checked again.... I don't think he will charge me to check them...but not sure...

I just want this to be the LAST TIME I pull the heads on this motor....

I don't think a re-torque at this time will seal them up.....

I would think that the cap would have blown before a head gasket would have. Does it look like its comming out of the bottom row of bolts? These bolts go into water jacket and could seep on you. I ussually put a little bit of silicon on the threads when I do heads. Good luck with it. That Sucks!

are you sure your heads are not warped also check the block and the heads for cracks take it to a machine shop and have them magnaflux it it sounds like you have 2 cracked heads or 2 warped heads or the engine block is not straight :rotfl:

I'm driving it daily right now.... just keeping the coolant levels up and she is fine.... I have to get my FSJ on the road before I tear into the Burb...

I will have the heads checked again... and figure out something about the block... I don't want to pull the dang thing out!!! All the cylinders are at 145PSI

I am pretty sure if it was a warped or cracked head (pretty unlikely they are cracked in the same place on both sides) might just be your gaskets. I know this won't help much right now because I don't know where you can get the stuff but see if you can put a colored dye in your coolant that might help determine where it is coming from.

I have the die.... but I don't think it;s the heads.... hehehehe.... found a huge crack in my year old Aluminum radiator :angryfir:

I got the new one in already ( warranty exchange) and I seem to not be losing any coolant now.... go figure.... the res is slowly going down... but not as much though

Will to the die test to make sure.....

not dumb... just unobservant

The rad was leaking from the lower drivers side and channeling thru the frame rails and dripping out the side.. and where I park is all dirt/rocks and never saw a drop on the ground... until I parked on a paved surface and BS'ing with a friend....

I pulled it that night.. called and got the replacement the next day.... I still have to to the die test to make sure on the heads... it's already 100+ degrees here....
