throttle housing coolant leak disco v8 2000

[MAD MAT]

got coolant seeping out of small square plate with 2 hoses fitted 2 it under throttle housing near air intake looks like 2 maybe 3 small bolts to remove . does this need some sort of rubber gasket . or just a bit of silicon. looks a bit fiddly thought i would ask . incase i need a new seal before i get into it. any body done this info would be appreciated

I was in the same boat a while back, however it was on a 92 RR so the plenum cover may be different, but the 2 pipes will go back to the intake manifold on the passenger side at the front. And from what I could tell, the chamber did little more than warm up the air on it's way into the engine.

So really you could just bypass it, or proper fix remove plenum cover and new gasket.

When I cleaned my plenum cover up when I did the top end, that chamber you speak of was fully blocked with dry coolant. The gasket is very simple and just a square piece of card with a 10ish mm hole at one side. So if you get some 0.5 - 1.0 mm gasket paper you can very easily make your own. If the little chamber is clean I would say it would take next to no time to sort out.

I know the part you mean .... The plate is thin and is easily bent with the tightening of the bolts

Take it off ... setup wet & dry on a flat surface ... Rub the plate surface till it's all flat (shiny) ... use Holimar3 as a sealant / dont overload (torque) the bolts, or you will bend the plate and be right where you started again .....

Also do the job on a Saturday, and make sure you know who's selling a new plate, Just incase it's cu-put

Am I talking about the right part Mike? under the plenum cover just before the butterfly?

I just did it up until my elbow clicked but I'm a rough bastard. There is 1 longer bolt as far as I remember, so remember where they go. I made a gasket and used loctite 3 as the sealant, great sealant, but like moly grease, it jumps out of nowhere and gets you when you least expect it.

Good luck.

My bro has this model, and the plate / bolt description fits the part that we fixed about 2years ago ....
Either way ... the answer is basically the same

Knowing our luck tho .... We could BOTH be off ...


Wonder if MADHAT will post a pic? .....

interesting,,
i can see where mines leaked in the past,,
and where someone has replaced the clips to stop it,,

I wonder if the hose IS blocked,,

one easy way to tell---

Disco is great. And for nearly 3 months I haven't had to put a spanner on my own car. Only one downside - it's just nor quite a RR... I'm a commoner now

If it is blocked you will probably find the hoses are ok, its the actual cavity that builds up with sludge. But as it is only a bypass of he coolant, it wont bother your engine at all

had 2 goes at it now . once just using red gasket sealant . second attempt made a gasket 4 it bloody thing still leaks . thinking about doing away with it all together and just joining the 2 hoses together. from what i can see it only heats a small area of alloy on the air intake throttle housing to warm air before entering engine . probably so it runs smooth a bit quicker on those cold pommy mornings . gunna check with local landrover guru if this is acceptable , unless there r a few of you out there that can say this has been done

It is what I was thinking, and mine was completely blocked. Never caused me any dramas.
