No it is not. Sounds like a leaking intake gasket which most chevy's are notorious for. Thankfully companies like Fel-pro make a "problem solver" gasket, which will elimate the chances for the leak agin.

I have a 1997 gmc sierra 5.7 vortec, just changed plugs and wires, now it hiccups at idle, And excessive white smoke and gas smellout the exhaust any ideas?

If you have white smoke out the tail pipe you have a problem with antifreeze entering the fuel system and burning with the fuel .
You see the white smoke isn't smoke its steam from the water in the antifreeze .
Witch leaves with 1 of 2 problems head gasket or intake manifold gasket .
Being that its a chevy engine I would say its the intake manifold they have had a problem with this disgin for over 30 years not enough bolts to much glue .
Over heat this engine once the glue melts and it starts leaking because of the pressure .
The bigger problem you have is if you run this engine the antifreeze will get behind the pistion rings any wreck the engine in under a month.
So do something quickly if you want to save it
Good luck

1999 Nissan Quest has oil smell coming through vents when heater or defroster is turned on

Oil may be leaking from valve covers from brittle or old gaskets and is letting oil travel down to and on exhaust manifold or other hot spot where it is getting Burnt off. Or had recent oil change and oil was not wiped off and is still dripping to hot spot.

Smoke under the hood

Could be alot of things but, here goes: Could be oil or antifreeze coolant dripped on the exhaust manifold; maybe steam rising from a broken or cracked hose or head gasket, or radiator cap gasket

well sounds like u just blew a head gasket check ur coolant level or better yet put some antifreeze in it and let it run and see if u have an excessive amount of water coming out of the exhaust and keep check on the coolant level and see if u loose antifreeze as i suspect u will
and if u r loosing coolant then its probably not smoke u r seeing but steam instead

take it to a mechanic and let them check it

could be just head gasket and bad exhaust manifold gasket (coolant leaks past head gasket into exhaust port then leaks out of exhaust manifold gasket)
or it possible that head is cracked too
Only way to know for sure is to remove head and inspect it

How do I replace the oil pan gasket on a 2001 GMC Yukon XL?

Changing the oil pan gasket on a GMC Yukon XL is realtively simple, but does require removal of the exhaust pipe. You will need a new oil pan gasket and a new exhaust pipe flange gasket.
Put the car on ramps or jacks to access the undercarriage.
Remove the exhaust pipe by removing the 3 nuts holding the exhaust pipe flange to the exhaust manifold. These nuts often rust and prior application of penetrating oil may be required to remove them without damage. Once the pipe is unbolted, work the exhaust system loose from the hanging brackets. In most cases the entire system does not have to be removed since there is enough room to remove the pan with only the front hangers removed.
Drain the oil from the engine
Remove the 10 mm bolts holding the pan to the block.
Remove the old gasket material and scrape any remaining gasket from the block and pan.
Install the new gasket. Forma-Gasket or a similar product may be used in small quantities to "glue" the new gasket in place and prevent shifting while the pan is reattached to the block.
Reinsall the 10 mm bolts in a cross pattern to ensure the gasket is compressed evenly. Do not overtighten the bolts.
Replace the pipe to flange gasket between the exhaust pipe and the exhaust manifold with a new part.
Reattach the exhuast pipe to the hangers.
Install the 3 bolts connecting the pipe flange to the exhaust manifold.
Fill the engine with oil.

1999 suburban usung a lot of antifreeze

Some of the V-8 engines like to leak out the back of the intake manifold. It then drips onto the exhaust and evaporates so you never see it, you just smell it. Look for it back there. You may want to have the system pressure checked too. If it is leaking out the intake, it is not an easy or cheap fix. I just did my 96 Yukon and it was not fun.
Good Luck and hope this helps.
