I'm having my 1999 Suburbans done for around $600 this includes an oil change and tune up.
Intake manifold gasket
1500
To replace the Suburban manifold gaskets, unhook everything on the manifold, from fuel lines to vacuum hoses. The manifold needs to be unbolted then removed. Clean the old gasket material, then install with a new gasket. Make sure to use factory specs when torqueing down the bolts.
The labor charge to replace and intake manifold gasket, on a 1999 Chevrolet Tahoe, is approximately $180. It takes approximately 2 1/2 hours to replace the gasket.
Where is the leak coming from. Most likely you will need to replace the exhaust manifold gasket which will require removing the exhaust manifold.
What gasket?
Remove the manifold and change the gasket. And voila!!!
No. which manifold gasket are you wanting to replace? Intake or exhaust?
Replace gasket why does gasket keep sliding
I found an independant mechanic, who works out of his own building on a farm, who does this for about $375
Yes, you must install a new intake manifold gasket.
The gasket is between the head and the manifold and simply remove the bolts and replace the gasket after cleaning it real good.
