Leaking head gasket

Posted on Aug 23, 2009

  • twdind Aug 23, 2009

    You say the over flow tube. I take it you mean the coolant over flow tube. If oil is in your antifreeze I would suggest checking the oil for water. The oil should turn light milky brown with water in it. Therefore, if this is the case I might sugest leaking head gasket. This is not a real big job, you just need the proper tools and a good repair manual.

Oil gauge stays toward the low side at idle, then go toward high side while driving, why or what could be the problem?


sounds like a higher mileage vehicle. the bearings inside the motor loose some of there clearance causing it to run lower oil pressure. once you raise the rpms the flow increases causing the oil pressure to rise. you can add lucus oil treatment to the motor and this may stabilize the pressure. if it calls for like 5w-30 raise the oil to 10w-30 this also may help to resolve the issue

Replaced bad break lines on 2000 chevy 1500. Getting fluid to rear but not front. Bled master cly. getting pressure on front line but not rear.


Open and allow the fluid to flow out as there can be air lock in the tubing to the rear. so remove the tubing once again if there is no flow and clear with an air pressure.
There after connect to bleed off the front/rear in unison to remove all air lock.

Try unplugging the mass air flow sensor and see if it levels out.If so I would change the mass air flow sensor.If not try the same technique with the throttle position sensor.

Why does my blower motor for my 97 silverado does not work?


Check for a blown fuse,
Check for faulty blower motor speed control resistor pack - (usually located in the air flow in the blower ducting),
Check the blower motor is ok; ensure it runs if power directly applied to it.
Check blower motor fan control switch is ok.

I would suggest to check to make sure the fan is not on backwards. I dont know if its possible to even put it on backwards. just check to make sure that the fan is pulling air thru the grill instead of blowing out the grill. Also look into the radiator and see if you can see any lime or sediment in the radiator tubes. It will be white in color.A small amount of scale on the inside of the tubes act as insulation, and keeps the coolant from contacting the tubes and transfering the heat to the tubes so the air passing across the radiator can carry it away. Just flushing the radiator wont remove the lime scale, the radiator would need to be remove and dissassembled and rodded out. I dont think you have a blown head gasket yeti,if it not blowing water out when its cold and you dont have any performance problems, runs fine, just overheats. You might try turning on the heater when it starts to overheat and turn the heater fan on high as it acts as a radiator and see if it cools down indicating the cooling capacity of the radiator is diminished

Around 1500 rpms or 55 mph engine seems to bog down


It sounds like your low on fluid, or your transmission filter is dirty and the front pump is not getting enough oil supply. Worst is your front pump is going bad. 
Check the fluid level and see if it's burnt. Good luck
