That should not happen...providing that you don't have a pressure problem from a blown head gasket, try roughing up the surfaces of the block and pump with 60 or 80 grit sandpaper to permit the gasket to "bite" into them better. Don't over-do this and don't create marks that go from the passages to the outside. Don't use silicone glue as in your situation it may be too slippery. Though it is more difficult to remove later, use a glue similar to the old "indian" glue.
Start the engine without water in it and permit it to run without coolant for two or three minutes to heat the glue and allow it to harden,(just enough to heat engine...too long can damage heads and other gaskets) then add coolant in a half hour or so after you have finished. Also, check that bolts are not too long and are bottoming out before getting tight.(though on most gm engines the holes go all the way through into the water jackets.)

I have a 2001 Durango SLT it overheated put gasket fix and it seemed to help but now no power when driving and dies if u let off the gas?? Replaced timing chains 2yrs ago

Gasket fix rarely will work and you need to do a head gasket repair and check the heads for cracks at local machine shop, it's a typical problem with those engines.

Why is my 1989 Toyota Cressida overheating?

sounds like you have a head gasket gone bad. these cause overheating and the compression gases cause the air in the system and to boil out of the system. as such will cause the heater not to blow hot air, as steam will contain heat very long. the white smoke upon start up is a tell tale sign that the gasket has blown and needs replacement. have a head gasket test done. it could also be a cracked head or even a block, but head gaskets are a problem.

2001 Chevy 2500HD 8.1. I have no real pressure at the schrader vale on the fuel rail. If I dump gas into the throttle body the truck will run for 4-5 seconds then die. I have replaced the camshaft...

You can shut off the regulator by removing the return line and blocking the return port. If pressure returns, replace the regulator. If still no pressure, check the fuel filter. Is there pressure behind it? If you remove it, can you blow thru it from behind? If the filter is not blocked, replace the pump.

1998 cadillac deville: I have replaced the water pump, thermostat and all gaskets. It looks like water is leaking between water pump housing and block. Any sugestions or advise on repairing?

If your sure the seal on the water pump is good, I would suggest go to the auto parts store and buying a new water pump gasket. Sorry to tell you this, but take the pump off again. When you have removed the pump, scrape and clean both the engine block at the pump housing, and the pump back to shiny metal( this happened to me a couple of years ago, rushed the job, and gasket was not properly seated).Now that both are clean, put a thin coat of gasket sealant on the pump, and put the gasket on. Apply some sealant to the block housing.Put two bolts(across from each other) in the pump housing before installing(to keep the gasket lined up) and reinstall the pump. Give it a couple of hours for the sealant to set up, then give it a try. don't forget to top the fluids. I think you just pinched the gasket( happens all the time), and is giving the fluid a gap to leak. try this, and let me know

Replaced water pump, flushed cooling system,no oil in coolant,still overheating after 30 mins of running

I don't see where you replace thermostat, when replacing water pump very good idea to also replace thermostat, if you done that and stillls over heat's, then you will need to do a block test any repair shop can do this or you can buy a test block kit at any auto part's, this test will let you know if you have bad cylinder head gasket's, you will not always get water in the oil when head gasket's are bad, about the only time that you get oil in coolant is if you have bad in take gasket, check oil dip stick for water.

Coolant overflowing out of expansion tank no boil no steam

As you've stated driving around town it's fine, and everything is working well. For the symptoms, there are 2 possible causes:
1. Your cooling fans are not working.
2. Your radiator needs to be replaced.
I'm sure you can determine which it is, and I wish you luck on your repair.

Heater doesn't work

This happens ALL THE TIME!! Heater core is likely plugged with rust, yes. but a garden hose fix will NOT last. and the reserve probably IS cracked on bottom, as most are.They are relatively cheap from Ford, though. Have a REPUTABLE radiator shop do a Genuine Power Flush to the entire cooling system (not an automated fluid exchange many shops claim to be a "flush") and THEN have them unplug the heater in a similar fasion. Now is the time to replace the surge tank (old one is packed with rusty sediment that is usually partially plugging the cracks in it, and not very cost effective to clean anyway). On older, very rusty 2 valve 3.0 systems only other issues are the rear of timing cover gasket often leaks a little, and the water pump impellers can become eroded away (from rust) and water flow suffers. So... watch for residue or dripping from behind water pump. If minimal, a mild leak sealant added to a properly cleaned system with refill and tightening the bolts near leak will do the trick--otherwise timing cover gasket and pump replacement is needed.
