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.
The gasket set is $55.00 The labor is $250.00
It should take about an hour to change the intake manifold gasket. This part can be replaced by taking off the intake manifold cover, cleaning the old gasket off and sealing a new gasket in the space and tightening the bolts. When other things are in the way, like the alternator, it will take longer.
to replace the intake gasket would be about 4 hours labor. parts would run about $50
I'll assume Lower Intake Gasket, since they tend to cause vacuum leaks. Get a manual from Autozone and expect about 4 hrs labor, you need to take off the upper intake manifold just to replace the Lower Intake Gasket. Probably should change/clean the PCV valve while ur in there. Good luck, man.
Intake manifold or exhaust? The complete job (parts and labor) is between $700-$900. depending on labor rates.
5 hours labor Book time. A good experenced mechanic can do it in about 3 hours.
The labor guide book gives 4 1/2 hrs. for a well trained mechanic to do. It has to be done right, are you will be doing it over again.
I was just quoted 5.5 hours labor to R&R the intake gasket on my 1998 GMC Sierra 5.7 Liter.
around 6-7 hours according to AllData
I just had my intake gasket changed on my 99 Monte Carlo for the same thing. My cousin is a mechanic and has changed the same gasket on several cars with the 3.1 engine. The gasket is about $60 - $75 plus labor.
