yeah, if you're not burning coolant or leaking it, if you're not burning oil or leaking it...
but it's pretty obvious when it happens.. especially if it's all coming out between the block and head.
but here's the situation your looking at to fix it if that's what happened...
(and take into account that you do ALL THE WORK, otherwise, put your car up for sale or part it out and make more money)
well.. nissan engines are overhead cams w/ timing chains.. which means you have to remove, the entire front of the engine.. all the accessories.. alt, water pump, p/s, a/c, then the engine's front covers.
the valve covers and all the air intake and crap around the top of the engine is what you took off first.
then when all the front stuff is off and valve covers are off with all the non essential crap out of the way.. you have to take off the timing chain, idler sprocket, and cams, then you CAREFULLY pull the heads (this involving an indepth unbolting/retorque sequence that has to be followed so you don't warp the heads)
then after an extensive cleaning procedure (giving, you had the engine covered during the long time it's opened) you put a head gasket on it and put it all back together making sure it's timed just as well as the dearlership could do it.
long story short.. it's cheaper to go out, find a replacement engine.. drop that in, and rebuild your original engine while you're hoping the one you dropped in lasts you.
hell, even if you didn't get the replacement engine, go out and spend 400 dollars on shop jacks and engine lift and stand so you can pull the engine and do the headgasket job outside of the car...
it's easier.
it's quicker.
it's more precise when torquing the heads.
and i've left a lot out of this... someone could do it easily, but w/o the equipment, it's takes a bit.

gd... if i could only make it past the lower class, i'd be rich. damn facists.
i've been keeping an eye on the white smoke and my coolant level. the smoke is only there for short amounts of time and not very often, but my coolant stays the same. my problem is when i'm driving the car has short second bursts of no power. it will also die without warning, not even while accelerating, but it still can do it while i'm accelerating. it normall shuts off, then backfires, then i can turn it back on for about 10-20 seconds. i've had to pushstart it on 53 (busse if you're farmilier with the elk grove area). i've replaced the fuel filter thinking there might be too much crap in it and it's not letting fuel through. i've also done the seafoam as stated earlier. my last oil and spark plug change was a little over 700 miles ago, it was doing this before the the oil & spark plug change. i've looked on other forums and some people have had this problem and they said it was either the fuel injectors or the coil packs. what are your ideas on this?
Your problem is not individual injectors or coil packs. It looks like you're having some general electrical problem. It could be an electrical problem with the fuel pump; check the grounds for the fuel pump and the engine. Make sure the ECU harness connector is secure.
i was looking under my dash to see if i could get to the ecu easily without taking the dash apart. and i saw a switch, for the clutch, that the wires to it had been cut and then connected so it is always on. i was wondering what this switch is for?
if you want to bring it up my way, I can do a quick check out of it.
Sadly, I have too much time right now (shop got closed down).
I seriously doubt it's the head gasket.
the white smoke may be condensation from the exhaust (more typically seen in the cold though) and the stumble/stutter is probably a different issue.(coils/injectors).
I have the 92 FSM sitting on my shelf.
the switch by the clutch is probably a clutch interlock switch.

yeah dude...
if your car starts at all..
it's NOT the head gasket, although, depending on how deep you get into it, you may end up changing it anyways... leaving yourself with a brand new engine if you throw in rings and valve seals.
i'm more along with Rogo.
it sounds electrical.
the clutch thing could be anything, could be a previous owner didn't like having to push the clutch in to start it, so they made a bypass for the clutch switch.
like Rogo said... go around the entire engine bay and under the dash, checking for disconnected connectors... bad relays, fuses, wires cut, corrosion/resistance.

i looked under the hood and my o2 sensor was unplugged for some reason. so now instead of a stutter it just boggs out and i have to push the clutch and it's better. but i've had it bogg out and then i push the clutch and when i let it out again after a second it boggs out again, and this repeats until it's done with whatever it's done with doing. could it be my o2 sensor? and last night my exhaust broke after the cat, i was wondering if anyone had an exhaust system from the manifolds back i could buy?
yeah, for a while...
then when you run out of oil and coolant...
your rings melt along with your bearings...
then you need another crank, head, and timing chain... possibly pistons.
then it doesn't start.
course, if it is bad enough, on certain cars, the engine needs a certain amount of compression to start... as do all cars.
i did say it wouldn't start, but i was thinking more of the compression part of it. after a minute it won't enough.

if your head gaskets are so badly blown that your car won't start then they have exhibited systems for a very long time. I have as of yet to see a car be that far gone that wasn't owned by someone on the southside.
