Hi Chaps,
I am basically looking to check logic on a non LR engine (but it makes no odds) I just want to sanity check it.

Long and short I have replaced a couple of coolant hosts which feed the waterpump. However the only way I can get to them is to take off a fitting on the engine to fit them back in. This is a metal to metal joint and has a gasket on it which is still there but separated with bits on both surfaces.

Option 1 : Clean down back to bare metal and get another gasket.
Q. Can i make my own ? I see you can get gasket paper but there are so many types, surely if I go for a medium size one it will be ok for most uses. Its a 40 year old vehicle and I hate paying for sub standard gaskets. Would you soak a DIY one ?

Option 2 : Whack instant gasket on it and torque it back up.

Option 3: Order replacement gaskets.

I don't want to be OTT its a gasket at the end of the day.
 
I would say make one to get you going, then order the proper one to fit at your leisure.
Yes clean back the gasket faces.
Gasket paper is all much the same just different thicknesses, blue hylomar is cartainly helpful.

I have made gaskets from cereal packets before, back in the good old days when I simply could not afford the prices of motorbike gaskets.

Whatever happened to using Kellogg’s cornflake boxes:oops:.

I needed to replace the thermostat body on an old Golf not that long ago. A genuine body was about £300, more than the car was worth, so I opted for an aftermarket brand. Of the three I was sent, one at a time after sending the previous back, each one had a warped mating surface and consequently leaked coolant everywhere! On the third time I smeared a decent bead of Loctite grey sealant on, voila! No leaks for the remaining 6 months of ownership before I got rid of it.

I think thats what we have at work, and iirc it is actually listed as approved for coolant, even so I have used it for everything!

Yep, it’s made for coolant. I now like to have specific sealants for specific applications eg. for fuel, for oil and for coolant. The Loctite stuff always seems to work well.

me to. Surprisingly long lasting with a smear of grease on both sides
 
Thanks for your replies chaps REALLY good stuff...... Its a chassis of restoration so I may just wait for the gasket but in reality I quite like the idea of making my own and having it fit correctly. No matter who you buy from its often knock off China crap and depends on the day of the week as to how good it is.

What is grease bringing to the table ?

I don’t know, inhave just had better success with cereal box water pump gaskets with a smear of grease than I have without.

to be fair I always use a smear of grease on any gasket (apart from HG lol) - I mean just a smear - to keep it in place while refitting, never had an issue. Just something my dad handed down to me and I have always done it
 
In the old days if you applied grease to the gasket it meant you could remove it in one piece and use it again and again
Some people would use sealant one side of a gasket and grease the other so the gasket would stay fixed to 1/2 of the component

my dad was quite tight. So reusing cereal
Box gaskets would be something he would definitely do!
 
Thanks chaps, against my heart I have ordered new gaskets. Seeing how difficult it has been scraping the old ones off I can see £1 each is a no brainer.
