All of a sudden head gasket is leaking badly. 81k never overheated. Beautiful clean car...any suggestions on what I should do or mechanic in NYC/ Westchester area?? Help, Thank you

 

We need some more information. You said it never overheated. Is there thick white smoke coming out of the exhaust? Is oil or coolant pouring out the sides of the engine? Maybe post some pictures.

 

yeah, check for white smoke from exhaust. while left running at a quickee store. i had that happen to me one night in my 4cyl leberon work car and knew it was head gasket. [as their known for that ]. as i saw the white smoke i knew what to do,loosen radiator cap one notch to relieve pressure [use caution] then i drove 2 miles home and proceeded with repair.

 

Thank you... NO WHITE SMOKE, Car runs great.... It is leaking not into cylinders but out side of gasket all over outside engine at gasket. Pictures of leak cannot see easy unless on a lift. Is pouring out sides of engine, as soon as warms up.

 

In your case you might want to try a head gasket sealer since you have no internal leaking or overheating. I'm 50/50 on fixes in a bottle but I've heard good things about K-Seal or Bluedevil. Bars can clog heater cores in some cases. Otherwise just search for a good independent Jag shop, unfortunately I'm not familiar with NY shops.

 

If you want to use a sealer use K-Seal, it’s a pretty small bottle less chance for collateral damage. Once the leaking stops drain the coolant when the engine is cold. Add water, warm engine back up till thermostat opens again. Wait till it cools down again and drain again, rinse and repeat till the water coming out is clear. Long and tedious process but it’ll buy you time.

 

Thank you, mechanic did say give stop leak a try.... nothing to lose, I am hesitant due to potential other damage and leak is fast, so still I am not convinced is head gasket but he says is.
Leak under pressure is under manifold cannot easily see, but after 15 minutes pours out all sides of block area. Cannot see source from above.
Did not film it. Is there any lower hidden hose that could cause this.
I could tow to a Jag mechanic yet far. My mechanic knows European cars well but German mostly.

 

I am going to try it but only concern is leak is so much volume I do not think will work and also why I do question it being head gasket.

 

Can anyone let me know if there is a coolant hose that runs under the manifold such as the TB coolant return hose Part no. AJ89746 that may be the leak in coolant but appear as if from below is coming from the around the head gasket?
Could this be cause of leak, since is leaking a lot quickly I am not certain is head.
Thanks

 

The HEATER FEED AND RETURN hoses are under the intake manifold.

 

Much more likely a heater hose leak. Your mechanic doesn't know jags, but he will be able to do the repair. The octopus hose should also be replaced.

 

Sitework,

If the source of your leak is from the "under-manifold heater hoses" this link may help you............
