Thanks,

When starting from cold there is a strange noise, sounds like a knocking, that comes from the drivers side of engine. Sounds to be just below plugs.

Tickover is rough but improves significantly as engine warms...

Its not overheating.

There is no major water loss although I do top up about a pint or so every couple of months, say 3000 mles. Recently did nearly 1000 miles in a week with no significant loss. Just kep an eye on it from time to time.

A bit of white smoke when cold but it is cold weather at the moment..

Cheers,
J

Thanks J,

It probably is due an oil change.

I will do that for starters.


What oil do you recommend?

Thanks Javars,

Are we talking serious amounts of white smoke and does it dissapear quickly as engine warms, also as a guide how quick will water reservoir empty hence overheating?

White smoke would go (initially) as soon as it warmed up but mine deteriorated so fast I stopped using it so there wouldnt be any further damage, interestingly the guy who rebuilt it said that in his opinion (20 years land rover tech) the p38 v8s dont suffer head gasket failure in the true sense, but they suffer with a lack of seal around the top of the liner, which is why so many have multiple failures.
