What is this noise? 300Tdi Day 5 Eureka!

[@mariebulmer231]

great to see someone take the time and effort to trace the problem loved watching this

[@BritannicaRestorations]

Thanks 👍

[@stuartmellor-3463]

Thank god for that, I’ve spent hours watching and sleepless nights wondering what the bloody hell it is.

[@BritannicaRestorations]

Now you can sleep easy!

[@Djehuti777]

This was like a detective thriller movie. Great work

[@kingy550]

Excellent diagnosis. It's a shame the head may need to come off, but I'm glad you've found it.

[@BritannicaRestorations]

Thanks!

[@iceman9678]

The "Britannica Restorations" sticker on the 300TDi looks great.

[@BritannicaRestorations]

That's the only way to describe a good restoration!

[@kabaottoemulsion1869]

OMG you have found it! Hat off to your dedication! I hope it is easily identifiable!

[@BritannicaRestorations]

It is! Thanks!

[@philss1]

Mike, the main learning I’ve taken away from this epic journey is to see if the noise is running at the crankshaft frequency or the camshaft frequency, as that reduces the potential number of causes down.

[@BritannicaRestorations]

Yes - when I spun the cam without the rocker shaft, I knew it had to be valve related - never imagined it would be a valve/guide!

[@joaogeada2494]

I would never suspect a valve...great detective work

[@BritannicaRestorations]

Me neither - sounded like a bearing

[@paulholland5412]

So glad you found it, excellent work 👍🏻

[@BritannicaRestorations]

Thank you! Cheers!

[@kinnellian]

Woohoo a six part mini-series - well done, pour yourself a wee goldie 👍 Having bravely identified the source, now grab more popcorn for part #6 "The Cause" With the rocker and shaft components withdrawn we have around a dozen pieces left - which one is it? Place your bets! 100/1 shot is the left side collet, 200/1 the right side collet, the Spring is evens, with short odds on the current favourite - the Valve, with the Seal coming in at 3/2...the Slide is tracking well at 4/1 - the Spring cup is at 15/2 and housewives favourite, the plucky little Lash cap at 3/5 - this is anyones bet! Roll up, roll up, lets see the colour of yer money ladies and gents - bet in play, but bet responsibly - we won't condone betting on the wee screw and washer that holds the guide, but we'll take anything on weasels, or other rodents at a generous 50/1 😎👍

[@angusabbott5615]

Well done , I wouldn’t have had the patience to find that, 🇬🇧

[@paulbarnard5267]

Now that was very unexpected. Can’t wait see what you do next

[@TriumphT100T]

This was better than a Columbo movie

[@BritannicaRestorations]

Just like Colombo - Just one more thing....

[@peterclavering]

More important than the squeak.......what is Colombos first name?

[@BritannicaRestorations]

Frank

[@Badfinger61-i4w]

Bonkers to think a valve could do that! Must be a one-in-million sort of thing. I’ll bet you’ll never see another like this.

[@BritannicaRestorations]

Hopefully...

[@stefanmazur3238]

Well done Mike top man. I know you would find it. Great work. Love watching your videos

[@BritannicaRestorations]

Thanks 👍

[@RoverAddis]

Finally Mike, you got it..I am intrigued by the Intercooler set ...can you please make a video on it before you send away this amazing defender.

[@BritannicaRestorations]

I’m thinking about making a video about the intercooler, so stay tuned!

[@lawrencewagaki2959]

We will be waiting tomorrow

[@markmulvaney5497]

proof we learn every day,😀

[@BritannicaRestorations]

Indeed, we do! First time that has happened!

[@scorpionrgp]

What a bummer, though glad i was in the right area in my comment on video 2😉 with valve lifter or maybe a slightly bent valve hehe, gotta dave been following these videos on edge of one's with curiosity. Great diagnostic work 👍👍👍🎉🎉🎉

[@berndeikers8924]

very very interesting - great detective work. pls let us know more about the history of this engine. the noise with the engine running was definitely a metal on metal banging. like you sad the engine didnt had power. to bad you didnt measure compression. anyway ... i wouldnt hesitate one second and take the head off to have a closer look what is going on. and also the rocker and the rocker shaft. but i dont pay the music. but what else can be done .... precisely i had to overhaul my s2a engine a month ago. blown gasket. all oil channels in the rockers were filled with a slaggy tar. rockershaft worn out too. i cant believe the engine was still running. what a genius design at its time. still wondering why and how on earth this valve was failing. and against what the valve is banging ...

[@BritannicaRestorations]

Yes, it's a strange one... it's definitely not your average wear!

[@grahamsmith3536]

Big content on this job Mike, excellent detective work, as annoying as it is its good at the same time , ive had similar things happen with different things and i will not be beat by it , top job , lets get the head off

[@BritannicaRestorations]

Most frustrating Graham...

[@BurnAndHackett_RC]

Good job on tracking down the canary in the coal mine !! Would it be worth pulling the valve stem seal off first, before removing the head ? Maybe, just maybe you only have a damaged seal and the valve and valve guide are OK.

[@BritannicaRestorations]

Hard to say

[@hyhgtsssassfilj]

Well done Mike. The great detective 😊

[@BritannicaRestorations]

Thanks!

[@nicholasviney5975]

Well done finding that

[@BritannicaRestorations]

Time to buy a Toyota landcruiser.mine is 27 years old .I did own a land rover mk2a for over 10 years so can understand what you are going through.good luck from the UK.

[@ottovink5766]

Oké. Just do not buy a newer one. You won’’t come back if you go anywhere off-road…..😊

[@BritannicaRestorations]

Sadly, very few Cruisers here...

[@locodriver601]

I think you are correct that includes the latest land rovers. Far too complicated with all the fancy electronics.

[@BritannicaRestorations]

Land Rover lost their base about 2000 - after that, computers took over - no more farmers with a set of Whitworth spanners to fix their vehicles - off to the dealers!

[@jameskerr5756]

At least you know what it is. Might be a ballache to fix though. Back from Yorkshire now!

[@GregPalmer2]

Aha number 4 hmm 🧐 valve may have touched top of piston and bent. I'm calling LandroverSophie and LR Time to help us.😊😊😊

[@BritannicaRestorations]

Close!

[@Reaper4367]

bloody valve! who woulda thunk it hey! Well snooped Watson! 😉😀

[@BritannicaRestorations]

Thank you! Cheers!

[@simonrowlands7472]

Thank god they didn't do a v16, good find

[@martianmusic1]

Well done Batman. Tho" shalt prevail.

[@gazzafloss]

Ah-ha, yoiks and gadzooks! Mike you've found the source of that blooming squeak. A trapped mouse perhaps?

[@AJB1]

What's the recent history of the engine up to the squeak starting? What bits are new? I had new valve guides in my old Beetle not so long ago, with new-old-stock valves, and for some reason some of the new guides wore out in only a few hundred miles. Not sure if the guides were reamed out to too small a diameter for whatever steel the old valves used to be made from? But one of the inlet ones went squeaky whilst driving, then stuck open.

[@beekeeperkev]

Valve stem oil seal working too well, usually they let a tiny amount of oil by

[@beekeeperkev]

Remember back in apprenticeship days old A series and B series BMC the seals were only on inlet valves

[@BritannicaRestorations]

Could be!

[@beekeeperkev]

@@BritannicaRestorations 🤐

[@lindsaysampford3190]

See my suggestion in the last episode!

[@ottovink5766]

Maybe the problem could have disapeard bij itself….😊

[@ianwallett7438]

Good job. I would be picturing some tool driving to fast through a flood if it’s a bent valve. 🤔

[@BritannicaRestorations]

Not a bad idea

[@ianwallett7438]

@ might be worth checking the intercooler?

[@deniscudahy4549]

Well that was a surprise 😮

[@BritannicaRestorations]

Rather unusual...

[@ianhellyer1473]

Congratulations, now that's a strange one. I wonder if it's the valve springs. Can they be removed with the head in-place?

[@BritannicaRestorations]

Yes, you can replace the springs/seals, but the piston must be at TDC or you run the risk of dropping the valve!

[@rickbear7249]

My father, a consultant mechanical engineer, used to have customers complaining about rattles and squeaks. As he always said, "Nothing rattles, something's jammed" 😅

[@stevenwrigglesworth1271]

Is the correct rocker shaft pedestal fitted at the front? There is a drilling in it for the oil feed to the top of the engine, the others don't have it but can be interchanged by mistake, the rocker box looks quite dry of oil.

[@BritannicaRestorations]

They are all the same on a 300Tdi

[@stevenwrigglesworth1271]

👍

[@Reaper4367]

is it the separator springs?

[@matthewhaddon599]

Taken a bit of time, but got there...just need a fix now. Spring broken or not seated correctly or bad valve?

[@jnewzealand4677]

I think I would change the tappet first then the head !

[@BritannicaRestorations]

I had 2 rocker shafts on an still the same

[@cabrini00]

I would like to see what the fix is.

[@BritannicaRestorations]

New guide and valve

[@metaldog7128]

Well well who’d of thunk it! But is it a bent valve? Or a Loose valve Guide ?

[@allthingsadventurous6568]

Genius

[@BritannicaRestorations]

Thank you! Cheers!

[@andygreen6383]

Only FOOORMEEEEDAAABLUH my San!!!!

[@BritannicaRestorations]

Thank you!

[@sstoneman5020]

By golly Mike, you found it. In the last place youd ever have looked. Probably the one and only time this will ever happen but as of now every Landrover owner will be left thinking about that squeak they can never find... Maybe, just maybe....

[@vincentwilliams3994]

Could it be a loose valve seat. Seen them break up on a series 11 and getting smashed between piston and head. Definitely don't want that happening even if it means removing the head.

[@BritannicaRestorations]

Seats were good

[@vincentwilliams3994]

@@BritannicaRestorations You haven't taken the head off yet have you?

[@BritannicaRestorations]

See last video

[@erictyrrell3560]

Congrats. I wonder if this engine had a timing belt failure in its past.

[@BritannicaRestorations]

That’s a very good question

[@tonypacke6954]

If that problem had occurred and someone took their truck into a main dealer they would have had to use the defibrillator unit on them after handing over the invoice. I'm sure your customer is going to look twice at your bill as I'm sure you have spent a great deal of time on this issue, and it's not over yet.

[@hbox21]

could be the valve seal ??

[@BritannicaRestorations]

New

[@alfredsteidle5035]

If the seal off the Valve guide is really seal.....you can't lubricate from the outside. So.....we will see...... let's surprise us!😅

[@BritannicaRestorations]

Replaced valve and guide

[@sarahdell4042]

Good job! What a weird failure.

[@BritannicaRestorations]

Bizarre !

[@sarahdell4042]

@This is one of those issues that gets moved from shop to shop without ever finding the problem.

[@BritannicaRestorations]

Indeed!

[@eamonnleonard9162]

At 150 dollars an hour that is one expensive squeak to fix LOL.

[@keith6360]

Off topic, I’ve never seen a clear colant reservoir like that before. Where’d you find it?

[@BritannicaRestorations]

I didn't buy it

[@jonatday]

They are common in the UK got mine from Ebay, a good investment

[@harveysmith100]

Sod it. I was convinced it was the flux capacitor.

[@BritannicaRestorations]

Better luck next time on these never ending Land Rover problems!

[@billb3444]

And so after five days and nights the dawn of enlightenment arose. Mike did smite the offending valve train and a bell ring soundeth and the way was clear to him. Off with its head sayeth Mike, bugger sayeth his followers and a great peace fell over the land. Peace reigned over the shop. 😆

[@BritannicaRestorations]

Thanks, that's about the size of it!

[@billb3444]

I know you are exhausted and so are we. Brilliant job.

[@BritannicaRestorations]

Thanks!

[@mpfrias]

🥳🥳🥳🥳🎆

[@georgramm]

Before taking the head off look at the rocker!

[@tonypacke6954]

He's using a bar to depress the valve spring, rocker shaft is removed.

[@BritannicaRestorations]

If you recall, I had 2 rocker shafts on and still the same

[@PeterMenzies-t4r]

Well done Mike, that was quite a puzzle. Maybe the valve kissed the piston crown prior to rebuild or just poor replacement quality valve?

[@BritannicaRestorations]

Dunno!

[@grahamsmith3536]

Bent valve stem

[@grahamsmith3536]

Wasn’t this a head you had storage Mike ?

[@BritannicaRestorations]

No - came with the engine

[@alanraitak3870]

£2000 find

[@allan4854]

Maybe it identifies as a mouse 🐁 😂😂
