Im 70% through my big maintenence job. I have taken off the air intake / injection manifold, and in doing so, im scared that some of the coolant has got into the cylinders through some of the intake holes. cant SEE any but cant be too careful.
Also a few drips (probably a teaspoon max) have found their way into the rocker area, and then down into the valey via the drain holes.

would i be safe to ignore this tiny amount in the oil, or should i drain the sump to be sure? and am i safe to, once its all back together, take the plugs out and turn it over a few times to be sure there is no water in the cylinders at all.??

if you are going through a big maintainance job, why not treat it and give it some new oil and a filter?

The only problem you could have with water going down the inlet is that if a lot is there then the pistons could hydro-lock when retarting causing major damage. Simple solution is to remove all the spark plugs and turn the engine over a good few times prior to restarting, this should blow out any water you have sitting on the pistons. After that any small amount of water left when you restart will burn off pretty quickly.

Its a old bullet proof V8 that's spent most of its life in 4x4's going off road getting covered in st,

Hardly a delicate race engine, if its only a tiny bit im sure it will be fine

Also what Chris said, isnt a bad idea ^

But no need for a oil change

Take all the plugs out and crank it over should clear all the water out oh and disconnect the fuel pump too.


Thats what we do with outboards that have been sunk and 9 times out of ten we can get them running again so i would not worry too much

I submerged my old range rover V8 in a lake once, this included filling the cylinders up with water, just took the plugs out and dried them off, look the air filter out as this had turned to mush and drove the 150 miles home with 2 tonnes on the back, it did not cause any problems at all.

I know it was a range rover but basically the same engine so I really don't think you have to worry about the amount of water you are talking about.

I'm a little confused by your opening post, removing the inlet manifold should only allow a little water to run into the valley (& possibly down the sump) if you drained the coolant before starting? I can't see how you would get it into the rocker area or ports?

It's essential to syphon out the rad through the rad vent IMHO, that way the block drains down through the water pump return and results in less water left up in the heads / inlet for a cleaner (less messy) dismantle.

I rekon mobile 1 in a rv8 is a total waste of money, everyone has their favourites and opinions, but why not use a 10-40 semi synthetic at half the priceyes

A drop of water may not hurt but all that work and then save peanuts on some oil and a filter... I would have to be very skint or be doing it for someone who had "known" my wife or run over my dog.

I buy a 25 litre drum of Morris Oils 10w/40 semi synthetic for £50 quid....does 4 oil changes, and a bit left over for topping up etcsmile

So with a filter, each oil change costs me about £18 quid.....thumbup

And that Morris stuff is plenty good enough IMOsmile
+1, the rover V8 is an old engine and does not need an oil like Mobile 1 which is for much more moden engines than the rover lump. When the Rover engine was a fairly new import to the UK Castrol GTX was a modern top of the range oil, that was a 20/50 which is about right for this engine.
