    The car is a non turbo SL model. I bought it and it has not even been registrered yet. I had the bumpers painted and parked it. If it has a bad head Gasket, wouldn't it smoke all the time? It only smokes sometimes and the smoke has a slight bluish tint to it.

    Start by dumping a bottle of injector cleaner in your fuel tank, if you want.

    I wouldn't be attempting to change an oil pump on a hunch.

    Blue could be rings letting oil slip buy and be burnt in the cylinder.

    A head gasket is the seal between the engine block and the head. As the head and engine heat up, there is expansion and contraction going on.

    Why don't you take it somewhere and have them check out your engine, you really should have had that done that prior to purchase. What is your compression in each of the cylinders?

    Hi, I'm sorry I don't have any information regarding to your question. However, I have a 95 3000GT(sl) that you can help me with. I like to know the position of the VIC (variable induction control) motor. The VIC motor is mournted (with three screws, two on the top and one on the bottom) just above the timing belt cover. There is, some sort of a alignment, the mark on the intake manifold must match with one of the three teeth on the VIC motor. If your VIC motor hasn't been tempered with or if you believe it's in the correct position, I appreciated if you can help me out!

    Thanks

    I have a 98 3000 GT (not VR4). There is no pressure in the clutch at all, when pushed in it stays on the floor. Before it went out it was jumping like it was out of gas. Can some please help??

    Its your slave cylinder. I just had that happen on my car. It spuddered and then the clutch went to the floor and wouldnt come back up until I popped it up. They're about $40 to $60 at the auto parts store.

    Do you know how to replace brake parts (like wheel cylinders on drum brakes) and bleed hydraulic brakes?
  • Options
    mitzu3000gtmitzu3000gt Member Posts: 4
    I have been reading about how to bleed the lines, I am no mechanic but the car won't move now so I figure I might as well try if it has to be towed to a shop anyway. Everyone I have talked to says that it is not hard to change, and I am broke and need my car running. I really just need some instruction as to where the slave is... Im thinking I should just get a manual?
  • Options
    kiawahkiawah Member Posts: 3,666
    Why don't you just get some of those folks that says it is not hard to do, to come over and do it for you. Have them bring the manual and all the tools, you buy the parts and fluid. Buy them a dinner, and you're set.

    Hopefully they've actually done it, and not practicing on your car.

    Hello new to the forum thought I would check it out. I had a few questions maybe someone can answer for me. When I use my AC for awhile I have noticed that the car runs bad and cuts out. Sometimes has problems starting and has died on me. When I do not use my ac I notice it runs like a charm. Any ideas strange thing.
    I also would love to install a sunroof for my car but not sure where to look or what type to put in. I would like to get one that is made for a gt.

    I just had my 95' Mitsubishi 3000GT tuned up at a local shop. When I got it back the engine is running much better but now the engine drops out and stalls when I am at speed and push the clutch in. I notice that the cam on top of the engine for the excelerator comes back not to a solid stop but a stop connected to some kind of vacume plunger, this would seem to me to give some adjustment to the excelerator if the RPM gets to low. Can anyone give me any info on this? 2ndly when I got the car back the speedometer was no longer working. The RPM gage does work fine however. I know the 95's are electronic, not mechanical. Does it sound like a wire got pulled loose when they took the intake off to get to the back plugs or is there something else I might look for? My mechanic seems to be stumped on this problem.

    Thanks, Jack

    I don't know anything specifically about Mitsub's, however for speedometer, many vehicles would have a speed sensor on the output shaft of the transmission. I'd look there for a loose wire.

    I have a 95 3000GT. Mine has an Hydrolic master cylinder for the clutch. If yours is a hydrolic cylinder it sounds like you will need to replace it. I did mine hydrolic cylinder right after I did my clutch because I still had to push the pedal all the way to the floor to get it to disingage and still it was hard to shift. After replacement the system works fine.

    My VIC motor has 4 teeth on it. as you look in over the driver side fender the mark on the intake is lined up with the last tooth on the far left on the VIC motor.

    Hope this is helpful.

    I have a 1991 mitsubishi 3000GT well i just started noticing white smoke coming out of the tail pipes when i take off . We checked the plugs they look good and the car runs real good. what are some different possibilities for the white smoke?
  • Options
    kiawahkiawah Member Posts: 3,666
    Blown head gasket. Water from the coolant, is getting into the cylinder, the heat is creating steam, and it is being shot out the exhaust. You'll find your coolant level down.

    Get it checked out and fixed fast, before the coolant ruins the engine.

    smoke is oil smoke. problem is intermittent.one minute bad, next minute nothing.
  • Options
    kiawahkiawah Member Posts: 3,666
    Oil smoke would be black/blue. Puff when first started is usually valve seals. Continuous smoke is usually rings.

    White smoke is coolant.

    Confirm your color smoke, and address as appropriate

    I cant believe a car can run so good with a blown head gasket dont overheat and there is no water in the oil. Strange but OK Thank you for pointing me in the right direction
  • Options
    Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    You can pressurize the cooling system with a pump, and then, while still under pressure, remove the spark plugs and look for coolant on them--or as burdawg suggested, run a pipe cleaner into the hole and see if coolant appears. Then you KNOW for sure.

    White smoke (like steam) is definitely a head gasket problem. There doesn't have to be water in your oil. There can also be oil in the radiator, or nothing at all (since the leak isn't bad enough yet and it's all burned up).

    If the smoke is BLUE, this is probably oil burning, either from valve stem seals, valve guides, or internal engine wear (rings).

    If the smoke is BLACK, this is an over-rich mixture, and has many causes but all related to fuel delivery and ignition, and more easily correctable than the other two situations.

    I have a 95 3000 and a few days ago i lost almost all pressure in the clutch pedal. I checked the master cylinder to check the fluid level and it was a little low so I refilled it. After that it was fine. but the next day I came back and I lost pressure again. I checked the fluid level again but it was full. Anyone got any ideas what might be the problem?
  • Options
    Mr_ShiftrightMr_Shiftright Member Posts: 64,481
    If you lost some fluid, you have a leak, and probably are sucking in air. You might check for wetness at the clutch slave cylinder down below, or wetness in your carpeting under the dash where the clutch pedal linkage goes through the firewall.
  • Options
    3kgtvr43kgtvr4 Member Posts: 19
    Yes check the slave. They fail more often than the master. Even if there is no wetness the seal inside can let fluid pass. Replacing it is not too expensive.

    not absolutly sure without being there, but it could a leaking head gasket,sounds like coolant being burned off in the heads! Check your coolant! Has the car been run hot lately, if so could be the head gasket!
  • Options
    1998lincoln1998lincoln Member Posts: 108
    Could be a blown fuse eighter under the hood or dash, look at ignition fuse,before you do anything alse! ohms test the plug wires, could be that, could be the ignition switch!

    How do I remove the valve body from the transmission in a 1994 3000gt fwd. I need to test/ replace the control solenoid valves.

    liz013liz013 Member Posts: 2
    My daughters boyfriend has a 1994 3000GT and when it warms up it stalls! Him and his grandfather can't figure it out. It will run until it warms up. Some guy told them it was the transmission, I've never heard of a transmission making a car stall. Anyone have any ideas. They are afraid to drive it to get admissions test done for the reason they won't be able to get it back home or stuck in the middle of the road.
    Help please, Liz!

    My husband says it sounds like the catalytic converter is stopped up! Has it ever overheated or had tune-up problems?
  • Options
    liz013liz013 Member Posts: 2
    No neither. He got it from a second hand dealer and it ran fine until one day it started doing this. I thought maybe it was the emergency shut off sensor or the fuel sensor.

    I have a 1992 3000GT which is in great shape. Lately when I start her up she runs real rough and stutters on take off. After awhile running everything returns to normal. CEL is not on and has new ECU. I can tell I soon as I start her up if its going to run smooth or not. Any one have the same problem or know what might be the cause? Thanks for any input. :confuse:
