I have a 2002 firebird v6 3.8 liter and my oil psi is @ 80 psi when driving but when I come to red light it goes down to 60 psi is that normal also when I take out my oil dipstick I get some white smoke...

when you drive the pressure should increase as the rpm goes up not strange at all for it to drop like that at a light . the pressure can change sometimes using different filters and oils too . normal oil to synthetic or also using a heavier grade so keep that in mind .

The dipstick should not be checked when running and that could be blowby from engine wear . but if checking when it is off and you get some fumes out after it has been running for some time then you have have some carbon buildup in the valve cover / intake . These fumes may not vent properly due to that buildup .

Lifter tapping when I first start engine then it quites

Either you don't have enough oil in the engine or you have marginal oil pressure (most probable). You may have some sludge in the oil galleys feeding the hydraulic lifters; this will impede the proper flow of oil and lead to slow pressure buildup there. You can take your chances with an engine cleaning oil additive, but I've heard of one or two cases where people did that and threw a rod some time later. Try an oil change first, and make sure you use a good brand of oil filter rather than a cheap generic.

Has a whistling noise coming from fuel tank. check engine light on. the code is p1443. why is it whistling?

It is whistling because there is pressure buildup in the gastank. The pressure relief valve is probably plugged up and malfunctioning. With incorrect pressure in the fuel system, the check engine light is being triggered. The code p1443 is reguarding the Evaporative Emmissions Control System. Hope this helps good luck.

I want to now if its true about the problems with the 1.8 turbo GTI vw about the oil pressure

The 1.8 had some issues with buildup of oil sludge in the engine due to the amount of heat from the turbo.I would suggest that if your having oil pressure issues to have the oil pan removed and clean the sludge from the engine. Also change your engine oil to a full synthetic such as royal purple or mobil 1.A k&n oil filter works well also.

Oil pressure low

DON'T DRIVE ANOTHER MILE !!!! The 1.8 is known for a sludge buildup in the engine. This is the exact symptem that shows its head. The car HAS to be TOWED to a garage before you cause any further damage. Do a google search, "vw 1.8 sludge", and see what comes up...

Starts and then dies and then won't start acts

Sounds like you have carbon buildup in the exhaust system. Check your vacuum pressure. High pressure reading means exhaust problem.

You need to have your exhaust system checked. Backpressure can cause serious engine damage if not corrected in time.

Pressure buildup in the gas tank which causes the car to sputter and die unexpectedly.

I have never seen or heard such thing. You have a different problem. Is the "check engine light on?" Gas tanks have pressure in them on regular bases and I have never seen car sputtering because of a pressure in the gas tank.
