The end cylinders can dissipate heat easier than the center cylinders. The center cylinders are a heat bank heat sink whatever term people want to use but the center cylinders just have to sit there in the heat that has no place to go.
I'm scratching my head as to why you didn't find the broken parts!!! makes me think that the previous engine rebuild was not up to Britannica Restorations standards. Possibly they thought that the valve guide was not that important so they stuck the broken guide in just to get it running.
Well it had me foxed - until this morning when I was fastening down the head I had to use the old bolts as I didn't have any new ones (which is OK you can use them 3-4 times) but the one near the manifold would only go to 37 degrees not 60 - strange feeling tightening down so I put a good used one in and it was OK So I think this has been running hot at some time and maybe the valve nipped in the guild? There was some old damage to the block - I have videoed what I found This vehicle did come form Eastern Europe
Hi good night I have a300tdi engine but the engine is smoking it bills over 1year ago is not the rings wath it can b . but ibouth a new head wath it can b can you tell me
Check the brake servo for leaks - they crack, and the vacuum pump then pushed more air into the engine crankcases than it can cope with, then oil droplets get into the air intake Common problem
Hi Mike, have a Defer TDI300 which has been sitting for a few years in under cover in a tropical climate. nw back on the rod getting a few niggily things which can generally spoil a fun drive. Minor oil leak /power steering leaks etc.. recently replaced the lift pump which packed it in. up fro a service for sure but also thinking of getting ahead of these - what would you suggest I should proactively change / replace for the long family drive coming up
brilliant fault find mike, just swapped my 90 300tdi for a 110 300tdi and was wondering if you reckon it's worth having an egt gauge (I.e from the likes of fourby uk) or just ease off on the hills? reason I ask is I beleive the 110 has a fuel boost pin and ring going by the puĺl from the engine and a bit of smoke, also the fuel pump inner cap bolts have been replaced with Alan heads rather than the standard torx headed ones, what's your thoughts bud? Thanks Aaron
@@BritannicaRestorations Reckon I'll get the kit from fourby bud, wish I'd have removed it from the 90 before it went as well as the RRC coolant level float kit!
I'm amazed you couldn't here it rattling about Mike... A quick question if you don't mind.... you say you keep parts in stock like the head, what happens when you buy a part and keep in on the shelf ready to be used and you fit it to the customers vehicle and have a problem? Obviously if you put the head on and you've had it for a few years I take it the original warranty has expired... Cheers..
The head I keep is reconditioned - pressure tested , re machined (inc. correct valve depth) and I warrant them myself as it was done locally and I was in control of the quality
Britannica Restorations Ltd ok cheers Mike, but do you ever get problems with other parts? I know I've had my fair share of faulty parts which I've fitted and something has given up a few months later! I just had it with a 8 month old alternator in Sweden and over a 1000 miles away from home, ended up finding a second hand one which was a 4 hours round trip in a hired car! So Can you still claim from the supplier if you have had it on the shelf for months but it's not been used?
Good question! I have a 2 year warranty on parts from my supplier - all I have to do is prove the part is theirs, (there is a special code on the box) fill in a claim form, and they offer me an instant credit (no return needed) or will ship out a replacement part After 20+ years doing parts you learn a thing or two I do not sell or stock Chinese starters or alternators - do not care who's box they come in -always OEM parts wherever possible. All brake parts are OEM boxed parts - cost more and the customer thinks I am ripping them off, but if they want cheap Chinese they can go somewhere else But parts on the shelf can be an issue - I have been slowly reducing inventory and as I now have a 72 hour FedEx service from the UK, it is not worth tying my money up on parts that are losing value and deteriorating Yes I pay more for shipping, but when you could see the amount of stock I had ordered special for people then didn't pay, it would bring a tear to your eye! So special order parts are always paid for in advance now I had lots of Series parts that I gave away to clubs to reduce inventory - there is only 1 customer with a 2a now who is loyal = they all buy from Paddocks on line and I know the margins they are working to, so I am not going to get into the 3% profit game as I do not sell in volume But what I do now is let customers provide their own parts for me to fit - and this is working out well - I charge 10% extra on my hourly rate which is the norm here in Canada, I am not responsible for duties, import costs, warranties and importantly wrongly ordered parts And I do not give out part numbers any more ( well maybe to you guys) But I used to spend a long time working out which part was right for the vehicle (as you know there are a lot of mis-matched Rovers out there), making a detailed quote - only for them to take my quote and buy from Paddocks You can spend hours on the computer working out part numbers, and the part has to include my time - as I could be doing something else!

Something you might be interested in.... My 300 has 300k miles and I get 435psi (30bar) on all four cylinders, is your engine abnormally low or mine abnormally high?
From my notes Expected readings of a crank test, with vehicle battery fully charged, compression ratio 19.5:1 should be 24 bar (348 lbf/in2) So yours is strangely high
@@BritannicaRestorations I wonder why, I usually rev the engine for just a couple of seconds more than you did (and I guess it should not make a difference) but as long as the pressure is even across all the cylinders I guess I am fine. BTW I love your videos!
@@BritannicaRestorations just checked, it's a three holes... I wonder if a thinner gasket could ever lead to a 25% increase in compression (from 24 to 30 bar). It would be an interesting topic for one of your videos.
Lol.... 11:13 did you just say Africa and other strange places? Very educative diagnosis. I am looking into importing a 300tdi engine into Kenya for my 4 cylinder petrol conversion. Would you be selling engines?
I have a hard time with old engines - so I nearly always end up stripping and inspecting them Imported one with no pistons in 2-3 cylinders and one seized up -both from reputable UK sellers So if I don't hear an engine run, I only offer a very low price, because I may have to rebore and regrind So beware engines on the floor!

I have 2 300tdi engines, one head gasket was blown so I lifted the other head being the engine was sitting for a bit. When I checked it I realized it had a deflection between cylinder 2 and 3 just like the other head. So I was thinking the the exhaust ports between cylinder 2 and 3 are next to each other and maybe that could be causing that issue...
As you say Mike, the engine has been rebuilt, I recon that when it was done, who ever did it did not inspect or check the head out, they probably fixed an obvious fault on the bottom end and stuck the head back on as it was. It has taken quite some time for that amount of wear to happen, but I have seen worse. Very good video Mike, which should be a lesson to many people, keep up the good work. Best wishes from Yorkshire, Rob.

It is always a good idea to fit an EGT gauge on a 'tuned' engine

Britannica Restorations Ltd a perfect answer Mike so thanks for that...
Take care and I'll be waiting for the next video!
Do you see any of the 2.5 NA and turbo engines out there? as fitter to the original 90?

Mike ile waży silnik kompletny 300tdi dziękuję za informację .

How many miles does this engine last? tank ! Florianopolis SC Brasil 2019
It all depends on maintenance - because these engines can run a long time, they tend to be neglected for oil changes and cooling system checks
Tenho um motor igual no meu defender e tem 980000km. Sem uma manutenção muito regular e até agora está completamente de fábrica com excepção do turbo compressor
thankyou :)
You're welcome 😊
...making Land Rovers better....one valve at a time.... :)
Nice one!
I not understand when you say one valve at a time

So I was thinking the the exhaust ports between cylinder 2 and 3 are next to each other and maybe that could be causing that issue...
Could be - I have a feeling there is something amiss with this motor - I will do another video to show what I found this morning

Nope - Genuine head!
