HELP- Stop Leak Question

[Michael2]

I replaced the inlet manifold gasket on my wife's Range Rover (3.5 EFI) yesterday. I opted for the more expensive "rubberised" version and I put sealant around the water ports and the cylinder ports.

When it gets hot, I notice a small water leak, [more fizzing & bubbling, than leaking] at the locations of the right front water port.

Before dismantling the whole thing,

a) what are my chances of succeeding with a radiator stop leak product?

b) which particular product would you recommend?

Thanks in advance.

I've had good results with CarGo Metallic Seal Up http://people.consolidated.net/cargochemical/prod_sealup.html

Super Cheap sell it.

My heater core was starting to really leak badly but has stopped with this. I will say, however, that I've had to to the heater several times and the leak stops for some time then restarts. The time before last I used Mukowt on the cooling system and that might have made it worse by cleaning it too well. It could also be that the hole is getting worse in the heater core.

I also used it on my engine when I had the slipped liner and it stopped water loss/use.

Thanks Ron.

Just to add to the above - there's no oil in the radiator and no water in the sump.

A mechanic friend asked whether the 2nd (R) manifold bolt (the one where the water appears) may bolt into the water jacket? - does anyone konw?

He advise removing that bolt and putting sealant on the bottom and trying that before a strip down.

well i have always found that they work well and for the price i would at least give it a go. Nothing lost if it does not work . But great if it does :D

I didn't think you were supposed to use any sealent on the inlet gasket...that's what the ruberised bits are for

I used the chemweld stuff in the tractor after a head gasket blew and I couldn't quite get a seal, and didn't feel like pulling it to bits again, its seems to have worked so far, and i have given it a pizzling with some slashing etc.

Okay, so here's what happened.

I spoke to a mate who owns a Natrad store and he got me some "radiator blocks" - that's about as much as I know about them, I don't know their real name and they came in a plastic bag, not a packet.

Anyway, he raved about them, and said they were good for blown head gaskets and all sorts of sealing issues. Crush the blocks and dissolve them in boiling water, bring the engine up to operating temp, pour the grey fluid into the radiator, and drive for 20min.

I told him after the initial dribble, there hadn't been any further leak, and he said, don't worry about adding stuff then. However the Rangie is at 430,000+ km and it does lose a little water over time, when I replaced the clutch at 406,000 I noted some residue from the Penrite coolant on the rear welsh plugs. I didn't replace them because I was already over budget, but more importantly over time and using a mates driveway. So I decided to follow the recipe and added the stop leak stuff. Hopefully it will cure the very mild water consumption. - The only draw back, is I can't use coolant for a few days.

The seller (who also has a work shop doing just Land Rovers), suggested I use the sealant on the water ports. - But yes, I thought you weren't "supposed to" either, but that most people did.
