Great idea for a teaching aide. It still fascinates me looking at the old cross sections of engines and weapons we still use in the training establishments. You can see that someone has taken a lot of time getting the cuts just right then painting the cuts red. Top content again, ta Mike.

Great idea. Confirms everything you’ve said about porting and polishing, etc.

[@BritannicaRestorations]

That's right - interesting to see how restrictive the exhaust port is - not much can be done so bigger turbos and modifications to the intake are not much cop if the gas cannot get out as quick

[@simonrowlands7472]

I have been wanting to do this for years ,to get an idea of porting the exhaust track's but looking at yours not much meat there, might go down the merc om606 fix plenty of engines over here 😉 keep up the good work 👍

[@BritannicaRestorations]

Getting a bit enthusiastic with the die grinder can ruin the head - very difficult if not impossible to rectify!

[@nickboylen6873]

I had my 300Tdi rebuilt by Turner, with their gas flowed head. I imagine they have cut up several heads to work out exactly how far they can safely go with their mods, but I wouldn’t trust a regular garage or a club member with such work!

[@simonrowlands7472]

Best way of power increase is NO2 150 bhp press a button and 300 bhp with no engine porting, as long as the tank lasts🚀

Nice one Mike, did the same thing on an old V8 rover head and made them into 40mm thick sections. Put the valves back in and painted up the surfaces different colours, water areas blue, etc. Sold them on ebay. Went like hot cakes.

[@BritannicaRestorations]

Great idea!

[@jamescunliffe9872]

I remember some guy in Norway who found out that the flow around the heater matrix was restricted so he drilled out the constriction and the heater worked twice as good as it did before, thinking this might be the reason the back end is always hotter!:)

Where do you attach the air when you test Mike? And do you need the holes cut out where the cylinders would be? You would see air coming out of the in/outlet ports anyway. Maybe just for a better view?

[@BritannicaRestorations]

I put a pipe fitting the same thread as the heater outlet on the back of the head - the valves need to be exposed to see any cracks between valves - otherwise if cracked, air could not get out Don't forget to block off the thermostat housing too!

Hi Mike. Love the videos. The 300 TDI is supposed to be reliable and easy to work on. Is the TD 5 in the defenders from 2000 on also reliable. I gather this is the first with a computer electronics associated with the engines in Defenders John in Ottawa

[@BritannicaRestorations]

Early days yet for Canada John as there are 20/30x more 300Tdi than Td5

[@jacqueshickley]

Thanks Mike, that was very interesting. Can you get better views of the cracks in the ports? They looked parallel to the mating surfaces of the valve and the seat, which I thought was rather weird.

[@BritannicaRestorations]

I will try but the cracks were lower than the machined surfaces for the valves

[@jacqueshickley]

@@BritannicaRestorations Oh, that close. Don't worry then

Hi Mike How would one go about changing their subscription rate through your website? Would it have to be cancelled and then started again?

[@MG-tx9yb]

Very interesting seeing the cross sections of the head. Could we get any benefits from porting and polishing? Looks like there is plenty of meat in certain areas? We’re you able to cut through the head with a regular blade or did you have to use an aluminum cutting blade?

[@BritannicaRestorations]

I used a tungsten tipped blade Some sections are very thin - I looked at a Turner ported head and I do not think they did much as the sand casting marks were still in the head

[@aaronmosby3815]

Great video! Turner Engineering is offering gas flowed headers for the 300 TDi. Are the removing some of that "meat" and do you think that increases the risk of cracks/reduces longevity?

[@BritannicaRestorations]

I has a look at one and all they seem to do is gas flow the valves - as far as I could see there was sand cast marks in the ports - I found no difference in performance - maybe on a dynamometer

[@terryatkinson899]

I bought a saw that looks like a jigsaw on steroids and I'm sure it would cut through that head like butter. Builders etc use them and it's cheap enough... just a thought.

Hi I was interested to see if anyone had made a steel head for a 300tdi, found a man talking about it in a forum was dated back to 2014, Australian bloke I think and he was trying to get interest before he made them but it didn't say if he made them or not. Do you think they would be any good or even if anyone did make them????

[@BritannicaRestorations]

Never heard of one - would be a complicated casting but the moulds must exist - however they will be for aluminium and a different shrinkage rate - a big investment for a 25 year old engine

[@glynsmith7142]

Mike, INTERESTING point, with the valves removed if you look down the inlet ports and have a good look at the swirl ramps you will find ports 1 & 3 have very small swirl ramps and ports 2 & 4 have much bigger swirl ramps. Put there by design or just bad casings ? Do any of your followers know why ? I’ve looked at several 300 tdi heads and they all seem to be the same, strange ! Are the brand new heads which are now available, have the same swirl ramp differences ? Glyn.

[@BritannicaRestorations]

I do not think the Tdi heads are designed for swirl - that was more on the lines of old carbureted engines

[@glynsmith7142]

No I think your wrong Mike, if you remove the swirl ramps in the course of porting the engine looses bottom end torque and you end up with very nice door stop. I consider swirl is vital in a diesel for complete combustion. Sorry Mike, but any other thoughts on the different size swirl ramps ?

[@SSSwilliams]

[@federicoacker5672]

What an interesting experiment you done there Mike !!, Immediately arises my confidence in my 26 years old original 300TDI head !!!
