P-Gasket - where did I go wrong?

BigRedMachine · Feb 22, 2021

Evening,

I replaced the p-gasket on my 300tdi Defender a year or so ago (following a nicely written guide on here!), I replaced the water pump and a few other bits at the same time. Noticed today that there's a bit of a coolant trickle down to the block (see photo), which I assume is coming from the p-gasket. I gave the surfaces a good clean before replacing with a new metal gasket and torqued everything as per the manual.

Is there anything obvious I might have done badly (or not done) that would lead to it leaking after a year?

Thanks in advance

did you put sealer on the metal gasket?

I always have and never had an issue.

Thank you - I don't think I did, which may be the issue... do you reccomend a particular type in this sort of situation?

I did mine with RTV silicone ... was yours a metal gasket ?

Thank you, I'll give that a go this time - yes, used a metal one when I did last

Dont know what it is I used, Its Ford stuff that I aquired

Its a silicone type sealer but black so not so easy to spot as some of the blue/orange/white stuff .

Sure it is not coming from water pump? I know you said you replaced it, but a trickle from the front area signals a leaking pump sometimes. Try to find exact area of leak.
