Head gasket on 1989 300SE

I have a 1989 SE with over 255,000 miles, and it runs good. However, the mechnanic told me the head gasket leaks a little, and it will need to be replace soon. Can I replace it myself? If so, how can I do it?

Hi Kevin

You have done well, with the 255.OOO mls.!

You could be opening a can of worms, to start stripping the engine and just doing just the head gasket.

I expect other major engine mechanical fixes needed, are not far behind.

Has your mechanic done a carbon monoxide test on the cooling system, and found it faulty ?
Or is the oil filler cap milky, or is there coolant staining down the block ?
Do you top up the coolant much ?

Let me know !

As its running OK at present, I suggest 1 jar of Bars Leaks Coolant Additive, in the cooling system, and monitor your coolant and oil levels for now, and start saving for a newer model !

Good Luck !

Don´t forget to give me a FixYa rating...... Please !

John.

If it were me, i would let the mechanic do it, simple because when you replace the head, after replacing the gasket, you will need a torque wrench, and need to know just how tight the head bolts must be. If the head bolts are not tightened evenly you will blow out the new gasket....

It wouldn't happen to be a head gasket. When a head gasket leaks it could be leaking into a cylinder which would cause it to start hard and would also cause it to overheat. I would pull the plugs and at least look at them.

The stop leak most like caused the thermostat to stick closed and caused the over heating which may have blown a head or intake gasket. Have the oil analyzed to see if there is coolant present and if there is you will need to determine which gasket needs replaced. On newer vehicles it's no small job to replace a head or intake gasket os special tools are required.

Where is the antifreeze going? cracked head or blown head gasket? This is a 4.0 with 217,000 miles . Did they have a problem with heads cracking??? Houston


Faulty head/head gaskets will usually show up as oil in your antifreeze. It'll be a brownish grey color with darker "spots" floating around. You could be leaking out of your water pump or w. pump gasket. It may only leak here while it's running and a small enough leak would be obliterated by the fan, leaving no visible evidence. Feel around the bottom of the gasket and see if it's wet when you park it next time. Make sure your radiator cap is tight and in good shape. Could be evaporating from there.

Clicking noise


No, this is not normal.
It does happen though but at 50,000 miles is really ridiculous.

If you had a leaking head gasket, then the noise was during the engine being on (running).
It could also have caused the pistons to "lock" when you tried to start the engine (water in combustion chamber, not compressible).

Did they change the head gasket and check the limits on the head (warping) or pour some gimmick in your coolant reservoir?
