Hello today I saw this little spot of something similar to water.
I cleaned it up and it was like mold. Here is the picture before and after cleaning. Engine was warm when I saw this,
What could it be ?
thank you.
is it something difficult to fix if this continues ?
If the plug is leaking you simply punch out the old one and tap in a new one. A bit of technique is involved. Cross that bridge if we get there. 'Tis no big deal
so basically is it coolant fluid ?
My guess is 'yes'
With the plug clean and shiny you might actually see a tiny perforation. But, if nothing else, if it fills up again and the liquid is the the same color as your coolant (green, most likely) then you'll know what it is
I went to the mechanic.
He told me that he rarely saw leaking from those seals.
To replace it he will charge me 3 hours of labor... that is $400 to have the job done.
Otherwise he told me to try with a stop leak fluid to put in the coolant tank. He told me to remove 2 cups of fluid from the expansion tank and pour all the content of the bottle in the expansion tank.
Drive the car for 1 hour, and he told that the leaking would probably stop.
Should I do it ? What are the collateral effects ? May I clog the radiator in this way ?
Any hints are welcomed.
He gave me this product to try:
Well, you may like to know that the official Jaguar manuals in th 80s on the XK engine advised the addition of a tin of Bars Leaks every time the coolant was changed.
Not going to argue with Frazer but I wouldn't...having used it in my RRover with catestrophic results as blocked radiator and gummed up cooling system. Many things have been recommended in the past which were found not to be beneficial today....just my opinion.
I was always told by my old man and his mates, don't put anything in the cooling system except water and anti-freeze (coolant) because it will block the system. Keep it flushed and fix leaks proprely if you want it to work like it should.
Clean the core plug 'till it's shiny metal then lay in some JB Weld. Let it set 24 hours.
Should stop a minor leak like this without having to goo-up the cooling system
Cheers

looks tricky to clean. there is some rust. Seems like I have to remove the cable management thing which is over there. I will use some thin sand paper to clean it better.
No. It can be broken when hardened. And, if you or your "mechanic" knocks out the seal to reseat a new one, force will be used.
I've seen the detritus of Barr's in a radiator. Not pretty. But, that was decades ago. So, I withheld my comments on the thought that perhaps the formula had changed.
so I cleaned up as much as I could and then I put pretty amount of JB Weld to cover the edge and the top of the surface of the core plug.
Hope it will work. I won't touch the car for 2 days. on Monday I'll try to run for 100mi
and see the effects.
Has anyone tried to place a core plug ? $400 seems overpriced to it as well as 3 hours labor.
yeah hope it will work fine...
I also have the impression he does not want to do the job.
I thought that the rail you were speaking about was the fuel rail is it the air rail instead ?
looks like it did not fully work. I Still have leak even if minor. And given that the core plug is now full of JB Weld, the leak will move to the cavity of nearby spark plugs... not good...
