you need to stop doing your car repair's in that hoody or take the strings off look at video at the 21.20 mark them strings could of got wrapped in a fan belt or anything and you could end up dead mark. take the strings out mark ive seen to meany accidents that way

Sounds like bottom end to me. Take the oil filter out and check for debris. Also drain and collect the oil so you can have a look if there's any bits in there

[@danbrown4517]

Definitely sounded like bottom end on start up...

[@kevinsilcock9392]

Little end?

[@kylerankin9433]

I would do a oil pressure test, it’s obviously got some but better make sure it’s making enough 🫡

[@craigvirgin8461]

Dean. Drop the oil and get the filter off and cut it open to check for sparkles. To me, that's a bearing at one end or the other of a rod. I think the sporadic spraying of the oil from the lifters is a symptom of a bigger failure, not the failure itself. And as others have rightly pointed out, tuck your bloody drawstrings away!

[@areasixdevelopments590]

Dean, here's two easy checks to see if it has destroyed a big end without taking it apart - 1) remove all spark plugs - put a long tipped screwdriver onto the piston crown wind engine by hand so piston passes TDC and is just descending - now lean on the screwdriver - if the big end is shot you will get a thunk and feel the piston drop at same time. 2) inset bore scope - if the big end has gone it's likely the piston would have hit the head and the carbon line on the front and rear of the crown will bare witness with a visible line that mirrors the squish margins of the head

[@MrCrugwit]

Good advice 👍

[@eyvhhidcgy7637]

To be 100% sure it’s not the chain, there are specs for the length and VCDS can measure the angles of the cams, can always check those specs to completely negate the chain as a possibility

[@VOLKZZORN]

Yes, I know the noise. Two cracked hydraulic tappets looked normal on ours, but when pulled they flew apart so no oil arrived and ran dry which caused this noise! But as some have already said, the pump is mechanical, unfortunately I don't know if that's the case then it ticks like that even if it's broken!

[@Redshift-]

Listen to the speed of the knock relative to RPM - That gives you best clue ;) As the noise gets worse as the oil thins it's pretty safe to say It's run a Big End Bearing - A gentle drive down the road and the noise will vary on and off gentle load with the most noise when " floating" between on/off light load as the bearing clearences are closed due to cylinder Pressure/Vacuum on the Rods. The Owner cooked the oil but good Main Stealer still sold him a service 🤣 Would say he killed it what that Oil pressure fault was logged😉

[@alexdeacon5494]

I agree, I reckon it is big end knocking 👍👍👍

[@MrHuismeester]

I love those episode where there is a problem to be solved like this Audi, it gut be anything and to make a journey to find out what the real problem is. When you are buying a car like this one as a sort of blind date, it makes it even more interesting what is cousin the problem. So cant wait to see what you find out !! Nice video as always !!!

[@DannyPaine-rw5yd]

I know someone who had the exact same issue after a service. Turned out when the garage removed the old oil filter the o ring stayed in there there then distorted when new one was fitted causing oil starvation. Good luck

[@tommytaylor8735]

Sounds like piston slap to me. I’d be removing the oil filter first and checking for metal shavings and then whipping the sump off and checking the big ends before throwing £300 into hydraulics. My money is on bottom end. Bottom end knock can be very deceiving. Good luck mate. I’m sure you’ll get to the BOTTOM of it. 🤪😂 love the videos btw 👍🏻

[@jedi-mic]

Before you do the tappets check their fuel pump it's mechanical you can get that tappet noise from a fuel pump, I remember the Old polo used to make an awful noise like that it could be a lifter on the fuel pump or something's not right with it. And I would check the oil filter so if it is the correct type and the return valve is working right and make sure you've got the correct oil where you're pointing out the loudest part of the noise is where the fuel pump is so my guess is the fuel pump or the cam to it

[@apoco_lips9957]

that noise is definitely pretty close to the fuel pump

[@mikeyzs]

It’s spun a rod bearing like many others have advised. Sump off, check rod bearings. You’ve got this ❤

[@konstrukcija1]

Please check high pressure fuel pump and cam follower, it also may be leaking fuel into the engine explaining that the oil level is slightly increaed. Very common problem with these engine types.

[@projecteuroau]

Actually sounds like it does have a little chain rattle on start for a few seconds. You can hear it on your initial start and when you started it again in the shop once it was put back together. I don't think it is your main issue however, it sounds like rod knock or a bearing issue. I'd drain the fluid, check for sparkles and then check the oil filter for shavings before spending any more on the lifters.

[@stephenmarshall9574]

Sounds like the timing chain. The noise at the first start up sounded like the chain rattling until the oil pressure buildup. Also I would check the oil pressure.

[@leeingram84]

Maybe try unplugging 1 coil pack at a time and run it, plug back in if no change and move to the next, see if it changes tone or clears, with no detonation may rule out piston slap / bottom end, feel like I've seen this before, same noise, ended up being shells gone, also partially blocked the strainer.

[@TeaVR]

Can’t wait to see the solution for this 👍 Watch those tie pulls on your hoodie dangling and getting caught!

[@SavingSalvage]

😬

[@Seary1996]

Happened to a lad who I work with got his hoodie stuck in the pulley he panicked and got his finger stuck lost half his finger

[@zakshipley3250]

Sounds like little end knocking not tappets do compression test pull oil filter cut open see if bronze in there

[@GarageItYourself]

The fact that the oil only squirted from a few of the lifters would say to me that there's either buggered lifters or an overall lack of oil pressure. Now multiple lifters may have failed due to low pressure but as there was a recorded low oil pressure code I'm thinking the pressure releif valve is being problematic. Thick oil on start up makes things quieter and then gets noisy as oil becomes thinner hence reducing pressure. Anyhoo, that's my thoughts.

[@AI-Records24]

I won’t pretend to be able to begin to diagnose this from my bed but I’m enjoying watching you do it though and hopefully get it sorted out properly next video!

[@dodgerboe]

If no sparkles because new oil & filter done defo replace Cam roller bearings & tappers with fuel pump shim, plus if that’s run dry … then complete an oil flush through so galleys are cleared .. new oil & filter then run a manual oil pressure check at idle then 4to 5k to see pressure values .

[@vincentking5122]

Sounds like either a worn gudgeon pin or could possibly be a bent con rod,maybe it’s sucked up some water? Try disconnecting individual coils with the engine running and see if the noise goes away or gets quieter as if it was the hydraulic followers it would make no difference to the noise with the coil pack disconnected 👍🏻

[@markuskarhulahti6555]

Check the rod bearing! I was once chasing also a tappet problem, the sound came from the valve mechanism, but ended beeing a rod bearing issue. This was a 1,9 TDI, but the sound is the same.

[@michaelmclannahan1165]

Loved the tappets explanation, don’t apologise for your diagram; made perfect sense!

[@Bodgencodge]

Read a few comments of those saying rod knock/little end. Sounds too slow for that. I took a snipet and slowed it down, counted about 7 or 8 ish taps per second of footage. 420-480 or so taps a minute thats half engine speed at idle, so definately a top end noise. Id hazard a punt at a cracked or siezed tappet

[@ReeceMccann-z6b]

[@lukebryant7607]

I would check oil pressure with guage before lifters. If oil pressure low within a few miles and new lifters noise will be back soon enough

[@billmaloney6077]

I'm really enjoying your videos! You mentioned the oil level was overfilled by 200 mil. That could happen if the dealership overfilled it, an injector was leaking, or the car was driven into water deep enough to get sucked in the intake and hydrolocked the engine. The injectors don't seem to be leaking now, though one could have been replaced. Seeing the owner just wanted to dump it, I'd suspect the latter.

[@dan0017]

Please do not ever divert from explaining what you are doing and why you are doing it like many of the other car KZbinrs. Great video as always.

[@peterferryman4905]

Just a thought, the hydraulic lifters (tappets), will make that noise if the oil is to thick (to high viscosity), could be a good idea to drain the oil and make sure it's the right viscosity 🤔🙂

[@bullvine2062]

My old Alfa sounded the exact same, that ended up piston slap. Changed the shells and worked out perfectly. I used a dial gauge and there was 50 microns play, just a thought to test the travel ?

[@Dovling]

Overfilled by 'at least' 200ml gotta pull the excess out before spending a penny, chased a similar fault around the houses on a motorcycle was convinced in the end it was the cam chain turned out it was overfilled by the owner on the last service, and its free to do 👍

[@dangleeballs8382]

Dean, that's a little end bearing, just had exactly the same thing on my VW crafter, exactly the same noise and symptoms, changed all the lifters, followers and cams and it still made the noise, then stripped the bottom end and 2 of the bushes had come out of the little ends of the rod, one was completely gone and the little end had become elongated causing the knocking noise.

[@aaronf4201]

Damn I love the in-depth, show everything aspect of your channel Dean. Great to see you on Chris’s channel too. Both awesome to watch.

[@dougiebrown9318]

Sounds like my old Mk3 Cortina used to, when the camshaft wanted changing

[@mcmotors100]

It will cost ‘nothing’ to fit the new oil bracket (that you have for the other engine), as if it makes no difference you can then use the removed one on the Skoda engine. If it fixes it you’d have to pay the £500 anyway. Good luck 👍

[@raiNofchAosFPS]

give it a service change the filter they are made of paper and when a car sits for awhile they become very hard and cant get oil to the top of the engine. a 2.5 is a strong ass motor. it doesn't just blow for no good reason! check pick up pipe as someone has said before.

Check Audi haven’t left the old seal from the previous oil filter on this is a common issue when fitting a new oil filter it’s double seals this happened on my Q3 and everyone thought it was timing chain tapper issues but just was the double seal starving the engine of oil

[@Alitechification]

I reckon one of the small end bearings is seized to the Conrod or worn into the piston.

[@johnblackwell5805]

Before you sink £300 into new tappets, you could move the ones you suspect are at fault to a different cylinder and see if the noise moves. Cheaper, but more labour it turns out you’re right as you’d have to strip and rebuild twice. I agree with others though, sounds too heavy a knock for tappets (via an iphone speaker atleast!)

[@jarandorelat]

I'd be checking the injectors in that area. Get rid of the hoodie g strings, i thought of it too when i seen you lean in. You're working on cars now, so get yourself five sets of full-length overalls, and on Sundays wear yellow budge smugglers over the top.

[@chrisvectra5296]

Pull the sump and check the oil strainer as typical VAG issue Also test the oil pressure valve another common issue

[@bendude6748]

I’d probably check the bottom end bearings may as well rule that out first

[@JamesAlan-s6f]

Lifters nakered possibly been over reved and lifters have popped out. But who knows could also be top head was starved of oil which caused some damage. But I'm gonna go with the lifters popped off

[@andynightingale7335]

Dean the wizard to chase the issue down. Well done m8

[@PNFarhan]

Try to take one by one coil off to se if the sound goes away at idle...

[@danielwilliamson5371]

These engines are well known for having timing chain noise issues relating to the VVT pulleys, my TTRS has made some similar noises in the past to then not make them again at random intervals on warm starts. Pretty sure the The Turbo Unit made an article on their facebook page pointing out why these cam/VVT sprockets fail. So potentially maybe one of yours isnt getting oil pressure at all creating a rattle. I think there is also a piece of gauze somewhere in the oil channel feed to these VVT pulleys that can also get blocked up with debris stopping it from building oil pressure Ill bet audi over filled the engine with oil to see if it helped quiet down the noise im curious to see what you find. Good luck! 😁

[@andychell7525]

Dean, I think you also need to check the rocker’s . The needle bearings may have collapsed on some off them , just a thought.

[@whyldsteve]

Great explanation of how a hydraulic tappet works Dean. You failed to mention that Audi roller bearings fail and the needles fall into your engine with disasterous consequences!

[@GreaseMonkeysGarage]

Dude check your piston heights I had exactly the same on my scooby and it was a slightly bent rod. Drove lovely just sounded like that. Same thing sounded like it was from top end…

[@PaulRansonArt]

Failed lifters is my guess as well. They can still feel good on a static test but don't hold pressure when running. Hot thin oil is the clue maybe

[@SavingSalvage]

Yeah and fresh oil isn’t as thick as the old oil so it’s being pushed out the tappet easier.

[@seedsaboveitall608]

You Need to do an oil pressure test ! could be a oil pump on the way out

[@Kingdonnerkebab]

Love your VAG videos so much. Can’t wait for the RS6 update vid Dean.

[@phillipwilliams4674]

As others have said - drop the oil and cut open the filter checking for metallic particles. Sounds suspiciously like a big end bearing to me, that'll get louder as the engine warms up. Hope it's an easy fix, but like you said, why would someone take a huge hit on a car unless they knew there was something seriously wrong?

[@neutonrenda2303]

After watching the full video, you can hear why the previous owner dropped it like a hot potato lol, can only imagine how it sounded at speed. He obviously thought the engine was toasted. Looking forward to seeing what it takes to fix.👍

[@MrBalchin]

Sounds like piston slap, stick a endoscope down the spark plug hole and check the cylinder walls for damage.

[@pdurchev]

I had a stuck lifter issue and the sound was very similar. It was clearing when the engine gets up to temp. I used Marvel Mistery Oil and that seems to have fixed it (I've done about 15k miles after the last "cleaning" procedure). It's odd that it's getting worse with the oil getting thinner in your case..

[@ctiley2212]

Get your garden leaf blower and blow air through the intake system which will evaporate the petrol.

[@andrewduncan9210]

Wow a lot of replies here dean. So, I doubt you'll see this. First off as others have said I'd drop oil and look at oil and filter first!!! As you've got the oil filter housing adaptor, you could try that. I doubt it will solve it. But It wouldn't cost you a penny and not the same scale as the tappets. The valves in the assembly if anything like the ea888gen3 bracket are 1. oil cool jet control valve and 2. oil pressure regulation valve for hi / lo pressure. I think the workshop manual was referring to the spring loaded antidrain valve inside the oil filter cap? Anyways, good luck. I haven't worked on the 5cyl RS3 engine btw. Thanks for the vids.

[@ClassicMinishorts]

Well the frequency at tick over is 6hz ish so if tick over is 750ish then its ticking at half rpm. Obviously if it was ticking over at 1500 then it a quarter rpm

Hi. I sold my previous car to copart for salvage. The gear box needed to be replaced. Which was not really worth doing due to the age. It did start run and move forward but because of the gear box synchro problem it wasn't a true runner. Could be somthing simmilar with your car.
