How difficult is it to replace the intake manifold gaskets?

[sebryce]

I just replaced the water pump and all hoses on my '98 Bravada. Now one month later there's antifreeze coming out from the back of the engine, between the engine and tranny... I "think" it's the intake manifold gaskets. Has anyone replaced these and is it difficult? Appreciate any direction and help as I have removed everything on top that I did to install the waterpump and hoses. Hayes warns you of the pressurized fuel lines? Appreciate any help as I am stuck.

i wouldn't rush to conclusions. take it a shop and have a pressure check done to find the leak. i did on my 86 4.3 and found a leak back there that wasn't the manifold. i forget what it was. the 80's wasn't a good decade for me.

for $70 one local shop here does a whole vehicle "used car inspection" that includes a coolant pressure test. even if you do all of your own work it pays to have a professional inspection every once in awhile and this shop lets me in and get under the vehicle while on the lift to check things out.
