Be doing my first Disco head gasket job soon..... Had a new mystery water leak start a couple weeks ago, pressure tested the system this weekend and found the leak above the starter....Could someone post a link or point me in the right direction of where to buy the complete gasket kit? I might do the valve stem seals also. Engine has 172,000, uses a little oil on long road trips, but has been a great engine.

 

I got mine from Rimmer Brothers in the UK. As a Canadian, shipping from UK is usually cheaper than from the US for some reason. I think it’s important to get a good quality HG, eg Elring, rather than generic.

 

After looking at Amazon finally...lol I will probably order this kit.

 

That's an Allmakes/Britpart kit. Not what I would go for.
As said above, better to look for Elring or something else more reputable. You might have to go beyond Amazon.

 

$219 plus shipping at Atlantic British vs 81 dollars and free shipping? That's a HUGE difference. I would copper coat the head gaskets. I have no problem paying 219, Im just not sure why?? Is their that big of difference in quality? This is why I ask the rover community. Thanks

 

I've had good luck out of the cheapie HG kits.

 

Try Victor Reinz then. I have them in my truck right now. $172 plus free shipping from Lucky8. lucky8llc.com/products/head-gasket-kit-set-reinz
Even at double the price, I would still pay that over Allmakes crap.

 

I have the same rear corner weep on the drivers side. So slow it doesn't even drip or show coolant loss over the last few months. Thus far I think it might only leak when cold then stops when warmed up. At this point I am hedging that it will fix itself. Happens right? But IF it doesn't I guess a head gasket replacement is in order. I hear talk about coating with the copper sealant stuff. When this is done do you mask off the firing rings? I was thinking maybe if the copper was only applied around the coolant channels it might help stave off this external leak coolant leak. Assuming it would squish under and not create a problem in thickness variation.

 

The purpose of the copper coat is to create a very thin "crushable" layer that fills in any tiny surface irregularities, both on the block and the head (or the block and the exhaust header). I use it on any metal gasket. No masking is needed.

 

I don’t think it will fix itself. I had the same leak on my P38. I finally decided to tackle the inevitable HG replacement, so I ordered all the bits. When I was disassembling it I found the rear left manifold bolt completely loose, so I think that was the issue all along. As I had the parts and was half way there I did the HG’s anyway. That’s just to say that it’s possible you don’t need to dig too deep. Also, like you, if it’s such a tiny leak I’d be tempted to postpone it for a while, but keep a close eye on it. Others here, probably more wisely, may suggest not postponing it.
