Vaseline is used to prime oil pumps for a couple of reasons... Oil can be used but as you say, it can and does drain away. There are also practical issues... Imagine trying to push oil into an old rover v8 oil pump and then pushing the gears into place before fitting the steel pump half! Impossible. Use Vaseline so it stays in the correct places. Vaseline is a lubricant and anti corrosive because it is petroleum jelly. And very important... the low melting temperature means it turns to liquid very easily and is washed away and diluted and easily evaporates once warmed in the engine oil. DO NOT USE GREASE... Grease has a much higher melting point and can easily block oil passages and refuses to melt until very hot. Death for a Rover v8 rocker gear!

[@BritannicaRestorations]

Yeap the rocker gear on this engine is shot What is your opinion on steel rockers for the V8?

[@simon1924]

Man thank you for that!!! I was already about to order the whole lot new (saved me a few bucks here !). My pump looks just like new, but it was so terribly out of metric spec... but I am well within imperial spec

[@eliotheasman5378]

Hi Mike why do they make your life so hard for things like this many thanks Eliot

[@greebo7857]

Love to see you get a 68mm spring in there, Mike!

[@BritannicaRestorations]

now that would be a good video!

[@ddnuk]

Also for pre-lubrication I can recommend red Clevite bearing guard or Lubriplate 105 motor assembly grease.

[@cycleinfrancecom]

Correct spring length is 54mm. I have hundreds of them in stock if needed!

[@ralphdadge302]

The 68mm spring [more accurately 67.82mm] is used in the 200Tdi engines oil pump relief valve.

[@itiswhatitis8174]

Great timing Mike about to do mine thankyou, did purchase new spring and a pump. Old spring 44.87mm and new spring 54.37mm ERR1084

[@BritannicaRestorations]

I wonder if it makes a lot of difference? very time consuming to try out! Still now I know the number I may pop one in and be done Thanks

[@ddnuk]

Spring length is definitely incorrect. I had the same issue and spoke with Turner Engineering who told me to ignore the manual!

[@BritannicaRestorations]

Thought so - makes no sense! Bet a few have been buggered by this!

[@nzrestoration9486]

Hi Mike went to use your discount code with Bearmach, was going to order a top hose, thermostat and some prop shaft bolts for a Discovery 1, all good they had the parts costing NZ $ 30 checked out, but wait there is more! Shipping $ 1670 .00 😂 you have to laugh. No wonder you tear your hair out in Canada! Needless to say I got them elsewhere!

[@BritannicaRestorations]

Good to know - I will tell them about itMike

[@Rob-cz7lg]

68mm includes the plunger height?

[@nickboylen6873]

68mm could well be the correct spring length for the 200Tdi and older engine oil pump springs.

[@fionanokelly]

When I rebuilt the 300Tdi head, the workshop manual mentioned that the free length of the valve springs should be 46.28mm, but the ones I removed and the new ones I had bought were both longer than that. It had no sense, that figure of 46.28 millimeters. I think they mucked up a lot of measurements on that manual...

[@BritannicaRestorations]

There are some things in the book that makes not sense

[@gorifranka]

As for the Plug torque, on the last part of the manual it says 17Nm. I have done a few the same way but most time I had to get new pump kit. Thanks

[@BritannicaRestorations]

Nothing in my book - but will take your word for it

[@gorifranka]

I don't know how to attach a photo of it.

[@gorifranka]

@@BritannicaRestorations What is your email address?

[@user-ug2nm8ep6o]

Hi Mike, Regarding the spring length it is probably the length including the plunger, on the other hand the length you measured on the spring sounds too low as a new spring should be around 55 mm. It would be interesting to see what pressure the spring holds, it is supposed to relieve at 50 psi if I recall correctly.

[@BritannicaRestorations]

I was going off the book but 50 Psi is not a high pressure so a few mm off the spring will not have that much effect

[@user-ug2nm8ep6o]

@@BritannicaRestorations You are probably right, was just wondering what pressure will it hold in such a condition.

[@harveysmith100]

Mike, be super careful using that impact screwdriver, they are more powerful than you think, even the 12v ones. They can break screws easily. Ask me how I know.

[@BritannicaRestorations]

Just a small shock will be ok - I rebuilt my shop with this 12 driver all the beams were 6 inch screwed not nailed very impressed st the power

[@marcovanstaden45]

Mike, I will need to do a power steering pump replacement for my 300tdi defender soon. I've never done it and can't find a useful KZbin video for it. Can you please do a video of how to remove and fit one in situ as I'm only a "driveway mechanic" 😂🤦🏻‍♂️ as well as and tips you may have. Thank you for all your fantastic videos.

[@BritannicaRestorations]

I would do Marco but I do not have a 300Tdi that needs work at the moment - give me a while and I will see what I can do

[@MrRobmellor]

Mike did a rebuild of a 3 bolt Defender steering box some while ago. If you are a bit more than handy as a mechanic, that video should be helpful you as it shows some of the downfalls to avoid, such as how to get the input screw out to replace the inner seals. HOW!!! do I know this. Because I did my box as I ran Mike's video on my laptop on the workbench as I did it. Good luck with your rebuild. Yorkshire Rob.

[@marcovanstaden45]

Thank you Robert, I've seen that video, I'm after something for the steering pump though. Mike did a video of a steering pump where the rear bearings failed, but didn't show how he took it out or back in. I'm sure it's a simple enough job, I'm just relatively new to fixing land rovers😅 and have LOADS to learn. Thanks for the input though and for taking the time to reply

[@MrRobmellor]

I have been very lucky in learning how to pull things apart as I owned a scrap yard and did it to recover the different metals from an early age, it was putting them back together that I found hard. Its a pity that you haven't got a scrap pump around so you can have a go at it without having to rebuild it again. I,m sorry that I misread your question, it must be an senior age thing. Don't be frightened of having a go, just be carefull, if I can do it, I,m sure you can. Once again good luck. Yorkshire Rob.

[@marcovanstaden45]

@@MrRobmellor I will have one shortly 😂 I've always been one for taking things apart and putting it back together, with varying degrees of success. It's just good to be able to see how it's done and any tips from someone who has done it for so many years.

[@jesusquik]

Thanks for the video Mike. It’s very helpful and very good explained as always. Could yo please recommend me any kind of vaseline to use it? Thanks!

[@BritannicaRestorations]

No special type - just regular Vaseline

[@jesusquik]

@@BritannicaRestorations thanks for your reply. But I suppose that is an specifical vaseline for engines or metals, right? I dont know which would be ok for that work😅

Hi mike, I’m about to rebuild a 1300 crossflow , is it ok using Vaseline on other parts such as mains , cam , cylinders etc ?

[@BritannicaRestorations]

NO! Vaseline on the oil pump only! I use this when building engines - use it neat - no oils added lucasoil.com/products/engine-oil-additives/heavy-duty-oil-stabilizer

[@mattluszczak6567]

Hey mike. Is there a solution for p gaskets? Steel gasket and semi setting liquid after block and sand job?

[@BritannicaRestorations]

yes - I use Hylosil never has an issue - make sure both faces are flat I had a customer once who had issues with the fan belt getting eaten - turned out he machined 20 thou off the rear of the water pump casting to make it flat - this also stepped back the water pump and PS pump!

[@TONYJUD57]

Just done mine, New P gasket installed dry, all up and running but before the thermostat opened it was leaking like a sieve, pulled it back out, cleaned it up, gasket gue and home made paper gasket on both sides, now no leaks, sometimes the old way is best.

[@matthewchapman538]

Hi Mike, Any chance you can cover the screaming 300tdi viscous fan bearing and what we can do to replace it? I've been told it is pressed into the timing case and people have changed them with bearings from Ford water pumps. Can you offer any advice on this? All the best, Matt.

[@BritannicaRestorations]

Matt - I have heard the bearing is available - here it is a water pump bearing you need to cut it down - you must be super careful to get the distance from the face of the cover to the pulley correct or the belt will chew up!

[@matthewchapman538]

@@BritannicaRestorations thanks Mike, is a small amount of wiggle in this pulley bearing normal? I'm thinking I'm barking up the wrong tree.

[@BritannicaRestorations]

You can get away with a bit of play as it is only a pulley - just be super careful dismantling the pulley flange - it is cast and breaks real easy and is not sold individually!

[@stephenlyttleton9032]

No gasket or sealer on that cover? How does that not spew oil? Every other part of a Land Rover will gush oil if it's spoken to wrongly.

[@BritannicaRestorations]

It leaks back into the sump

[@unclesam44]

Thanks, great video! Did you ever experienced scenario of long (c.a. 10 seconds) no oil pressure after prolonged stay i.e. 2 weeks? Pressures are relatively ok (1.5Bar at idle when hot and 2.5 at idle when cold and higher when you rev up , spring is 45mm) and next day or few days startup pressure is ok. however after prolonged stay it takes long time to build pressure up.

[@BritannicaRestorations]

Sounds like oil is draining back - could be the relief valve not seating properly?

[@unclesam44]

Initially I've thought it could be suction pipe mesh clogged or o-ring failed and sucking air in the beginning. But after dropping sump mesh it looks very clean. Relief valve seemed to seat properly but is hard to diagnose as when you unscrew it fall down. Doesn't show any serious wear signs either, but will double-check tomorrow. For now plan to fit new spring and suction pipe o-ring in next two days and put all back together. Then run the engine and leave it off for two weeks. Will keep posting on this.

@@unclesam44 Hello unclesam.....I am facing the same kind of issue with my 300 TDI ( 1995 115Mkms). I set up a workaround by filling the oil circuit at oil filter support, thanks to a small pump moving oil from the sump (waiting to have the real source of the problem). Did you make somme progress on this ?...Thanks

@@martelmarteau4502No. Still have the problem. New pressure valve relief spring new oring on suction pipe - no results. Main bearings (crankshaft / connecting rods) doest seem to be in excessive clearance, as I would result in knocks/rattles and engine seems to run fine. Might be leaks on camshaft bearings. no idea so far.

Always worry Im trying to teach my grannie how to suck eggs when I comment on these video's, but still... Ever tried vapor-blasting on alu' stuff? Does a great job of "peening" the surface, which means you end up with a shiny silver surface that wipes clean, rather than a dull grey surface that picks up muck.

[@BritannicaRestorations]

Actually I did consider a vapour blaster but I am desperately running out of room! If those cabinets come on special again i may build one

[@CLOWNUK]

what miles does the pump need restoration

[@BritannicaRestorations]

Normally there is no set mileage, usually rebuilt during an engine rebuild or of there is a problem with oil pressure

[@CLOWNUK]

@@BritannicaRestorations when i fitted a new head gasket at 185000 i was going to replace the valve caps (because of storys of them breaking in half) and found the uni parts replacement caps were thinner than the ones in my 300tdi engine, maybe from 4000 mile oil changes.

[@mattluszczak6567]

Mike dont have volume. Is it my side of things?

[@mattluszczak8095]

Never mind mike all good not sure what happened there

[@tyronekelly2672]

The metric measurements that you gave for the clearance of the rotor are incorrect by a decimal point you quoted from the paperwork 0.025mm - 0.075mm (0.010" - 0.030"). Remove a zero to give 0.25mm - 0.75mm which is equivalent (without splitting hairs) the same as 0.010" - 0.030". Obviously a typo error and wasn't very well proof read. PS I haven't finish watching the video incase you corrected it later on.

[@petermillecam6087]

Not the first error in a manual...bleeding of the gearbox clutch pump for a 2,4 tdci, they say turn the nipple 2 turns.... you ruin the pump... It only needs a quarter turn...
