Lots of white smoke

I have lots of white smoke with a pungent smell coming from the tailpipe of
my '94 Chevy S10.

Is this a problem I can diagnose and solve on my own?

I would be checking the coolant level expecting to see it low from a bad
headgasket.

In addition to above, if you have a V6 it could be the intake gasket.

Does it run bad at all or stall at any time?? What size engine??

It's a V6. It does run like it is simply chugging along. Recently, it
overheated and I had to have it towed where the mechanic replaced the
coolant and heater hoses, which were leaking.

If it overheated then started running bad it may be one or both head
gaskets.
A compression test will let you know which head. It would be best to
check both sides.

Depending on your skill you may be able to fix it yourself. But a
mechanic might be better.
If you do decide to do it yourself make sure to research it before you
start.

It's coolant. The REPLACE ENGINE light has come up on the dashboard.
Or at the least, the head gasket.

Could possibly be ATF being sucked through the vacuum modulator, if
your transmisison has one. However, based on the statement that it's
overheated, I suspect that previous posters are correct and it's
either intake gaskets, head gasket(s), or both. (the intake gaskets
have to be replaced to replace the head gaskets, anyway.)

If the coolant level is low, check the oil. If there's any sign of
"milkshake," just start tearing it down, it's at least one head
gasket.

If that's the case, I'm guessing you have a blown head gasket at a
minimum, warped/cracked head if you're less lucky, or a cracked block or
holed piston if you're really unlucky.

I am taking it apart to see if the gaskets should be replaced. However, I
am having trouble getting the rear exhaust manifold bolts off, there is not
enough clearance to get a insert normal socket and ratchet.

Should I buy a "thin profile" socket or is there another way of removing
them. The bolts are not only hard to reach in a tight space, but are
recessed as well, so it seems the only tool that can get a grip is a socket.

just buy a cheap six point socket and grind the diameter down until it
will comfortably fit in the recesses. You'll probably crack it before
you're done, so go ahead and buy two.
