i have a 95 Camaro with a v6 3.4 and i changed the valve cover gaskets and the
intake gaskets and now when i start it, it begins to smoke white and starts to
squeal in the front of the engine. Does anyone know more or less what it mite be?

Sounds like you screwed something up ! Squealing from the front is probably the
serpentine belt. Maybe it is not on correctly. White smoke is usually burning
coolant. Wrong gaskets ? Gaskets leaking internally?

WHITE SMOKE IS OIL BURNING RE CHECK YOUR GASKETS OR CAM SEALS

BLUE smoke is oil, White is coolant!

Transmission control solenoid where is it locate
If you are referring to the Pressure Control Solenoid, it is
located in the valve body, behind the trans side cover on
most front wheel drive GM vehicles.

I HAVE A 1999 OLDS ALERO WITH A 3.4 ENGINE. I REPLACED THE ENGINE
WITH A 3.4 OUT OF A 1999 GRAND AM. MY QUESTION IS..... HOW GOOD ARE
THESE ENGINES?
This is called a Milkshake. The coolant is mixing with the
engine oil. Have it repaired QUICKLY. Engine damage
will occur. Most likely the intake manifold gaskets.

I also have another problem with my 94 century 3.1 . When my car is hot, after it
and driving for and then shutting it off, it doesn't restart until the car is fully
cooled. Ive replaced the crank and cam sensors and after replacing the cam i got
a P0341 so i replaced it again but same thing. When I try starting it, it might start
for a little but u can hear it chugging and then it usually will cut. Sometimes I try to
give it gas but it will chug and then cut. If I'm lucky and feel like it, I can pump the
gas till eventually the car catches but I feel like this is damaging the car and it
doesn't always work. I'm lost with this problem and I'm not sure if it has anything
to do with my rough idling/stalling problem but this really makes my car useless
and its driving me crazy. Also, when i do get the car to start and its hot ill put it
into reverse get out my driveway and then the second i drop it into drive and hit
the gas I basically lose all rpm and the ca!
r then stalls out. No one has been able to solve this for me and I REALLY need a
fix because I've put more money into this car then it is worth now so I really want
to fix it up.

I have 97 transport,  3.4 and it won't keep running after I try starting it. I have
checked the fuel filter, it was OK and there was plenty of fuel pressure also, so
that rules out the fuel pump. Then I checked the fuel regulator, and no gas ran
out of it when the line was disconnected. I'm. Stumped, can anyone give me some
help with this problem? ?

I've been having heating problems with my 2001 Oldsmobile Alero with 3.4.  I've
replaced the water pump, thermostat, and belt, however it keep losing antifreeze
and heat.  I've taken it to several mechanics telling me that there were different
issues each time.  The last diagnosis I received was that I may have a cracked
gasket.
Yes, you could have a bad intake manifold gasket- very
common. Also may have a blown head gasket.
