Hi, indeed they did not change this last bit, it is not listed/shown on the hoses microcat schematic as a rubber hose so they did not order it back then.

The whole engine was clean when I got the Rangie 1.5 years ago so it may not have been cleaned then or this came out since in about 2000 miles.

Do you reckon this is oil or coolant traces?

I will clean it all this weekend before driving to the indy.

Rocker cover gasket and bolts were renewed upon purchase during the overall, major servicing, including coolant flush obviously

Thanks Craig.

Then it means it leaked from the rocker cover gasket since it was renewed 2000 miles ago or it was not cleaned when they cleaned the engine pre-gasket replacement.

Either was, not a big deal: weekend work => clean it all then retighten the bolt. then check again in 200 miles

Any trick to clean this as the access is ridiculous from either above or below (exhaust pipe in the way)
Also : WD40 to get rid of most of it then brake cleaner to finish it off or brake cleaner right away?

have you not discounted the valley pan seal? if you research, you will find that there is a tendancy for the valley seal to leak a bit, and there is an fluis escape path on the left bank. for coolant to run into the bellhousing 'inside' area and drip out on floor, there is a small hole at rear of block, to drain any liquid on the valley between the head and inlet manifold. if you were to dib a small pice of tissue on a long nose pliers etc, towards the rear of the valley you might find that this area is wet. mine is due a valley seal change as has same symptoms.
remedy here,
look at 6.30 mins for drain hole
its not an expensive repair, its a job though!

Thank you John, watched and quite interesting indeed. Wil check for leak there indeed with some paper towel.

However, my original leak definitely came from the upper part of the bell housing, on each side (right and left), not at the bottom of the bellhousing where you can find the rubber cover seen in this pic.





Would it come from here shoudl it be coming from the valley pan?


cleaned :

I would simply use brake cleaner J Thumbs Up

The rocker cover gaskets are a NIGHTMARE to stop leaking! Ive seen far worse than yours after returning from a job at the MD's! One customers car has been back 3 times so far & still leaks!

Merci Craig, somehow reassuring - we have a 1500 miles Adventure planned and I can not afford to break down during the Adventure. Censored

Will investigate for valley pan drain hole traces and replace the short hose too.

NOTE : Rangie does not loose coolant, though since purchased I have seen traces round the expansion tank cap, but collant always clean. l=Oo\________/oO=l l:OolΞΞΞΞΞΞΞloO:l

its possible your valley seal is leaking and the little hole in back of block is blocked, so it overflows, down outside (and inside) of bellhousing. that hole enables water to drain down rear face of block, round the rear seal and down into the bottom of bellhousing. you could remove the bung and put finger in,(engine off!) to see if wetting is there.

this member did a parts price request to ducky-Dan. http://www.fullfatrr.com/forum/topic26219....valley+pan he may have done the job, or pasted the list from another thread (that i have definitely read,) showing it in pictures etc. i cant realy look now. , BUT, you dont actually need all the parts listed. ie the pcv you only need the clip on diapragm, at £15 (ebay) and the valley pan you saw you dont need, just some decent RTV sealant from the youtube clip. You wont need the top black cover, You should change the inlet seals, as they harden, and leak. and the rear coolant mani. gaskets as they are going to tear, and the cross-pipe O rings all four. being carefull not to push them through and losing them etc. ie with vasalene applied etc.
(membername) Verydisco, i have this job to do very soon. i have already done my timing chains, -2 yrs back, and i am losing small amounts via the valley drain etc. waiting for some car downtime, and weather window. i shall be changing rear hoses, valley seals, rear cross manifold gaskets, pcv diaphram, all four o rings, cleaning my injectors, (even though i use LPG!) and tidying up its appearance, WITH the inlet ports well plugged with cloth etc. (unlike the youtube clip.) With our bmw engine we can always search youtube for tips via BMW m62tu44 etc. i have found many good teardown/repair/general problems. not using range rover in search etc.

Thanks johnboyairey,

I already did all the hoses and the PCV, so I guess I will follow the video, replace all seals and see.

did all the guys fixing the valley pan hose has any coolant loss though, as I do not miss any coolant in the system.

Today's update.

Cleaned it all up, went quite easy.

Investigated the valley pan leak and indeed there are small traces of coolant, but only a drop or two right by the dedicated drain hole. Nothing near as bad as the one in the video, so this is most likely not where the coolant came from.

I will drive 60 miles tomorrow and double check if there is more once the engine is hot.

However, I have noticed green/yellow traces on the rear cast aluminium coolant "header"or "water bridge".

Check pics please and let me know if these traces are consistent with coolant leaks - it seems these gaskets sometime fail with time.

The short rubber hose that will be changed does not show sign of leak besides its rusty clamp screw.








Thanks again you all for your time check this - I am sure it will help many others Thumbs Up

Extra question: on these pics, should the rubber hose rest against the pipe's rib or should it have been refitted over the rib?

Otherwise, nothing noticeable here :


May end up changing this rubber cover as the material is not in tip top condition

Hi gang,

Drove the beast for 30 miles, and checked upon return.

The couple of drops standing down the valley pan are now gone (from the engine's heat most likely) and there are traces left, see below :



No traces below :




No humid traces below the water bridge either:



No leak on the expansion tank :

Click image to enlarge


Click image to enlarge




BUT (there is always a but isn't there?)

I found these traces on both wishbones, fitted 2000 miles ago. Not sure what they are or where they come from, along with slighly greassy spots on the steering rack gaiter (replace 2500 miles ago)

Right, let me know what you all think and if there is a link between coolant leak and traces on both wishbones

going back to the valley rear bleed hole, (you can see it in your pictures...the tiny pool of liquid, might be coolant, in its boiled down state. ie the water will have boiled off leaving neat greasy coolant? is this being thought of as clean engine oil from rocker covers.??

Hi,

This was definitely coolant, but very little and indeed it dried during the 30 miles trip. l=Oo\________/oO=l l:OolΞΞΞΞΞΞΞloO:l
