Yes, not one of the easier ZD30DI jobs I've undertaken, did a bit of a writeup in my build thread.
I've not had the problem with oil flowing into the GP holes while cranking, to check if fuel is getting through to injectors I've never had to crank for any longer than 90 seconds.

Yeah I see that with the last successful IP change I done on my own daly driver,once I fitted it the engine was kicking straight away litterly which I was surprised about. This time round though I knew it's just a no show. Anyhow, sorry about the delay with the short video. I think it's eye opening,I will load it when I get a chance. In the meantime I have made a decision to get this pump rebuilt. End of the day it can only add money to the Patrol once finished. I spoke to the specialist and said I'm fussy about paying this sort of money so what is done for this cost. He said all gaskets and seals, all new elecs, ECU and sensors and anything inside the pump that looks worn after a thorough cleaning gets replaced. End result is an as new pump. I am trying another company this time,they sound more specific about things.

Just a quick update. So I have sent off the Injection pump yesterday to the diesel specialists in Cashel county Tipperary and today I got a call saying to me that the cost is 850euros but if the hydrolic head is the problem (Rear distributor) then it's going to be 1250+vat. Funny I wasn't told this before sending the pump! 🙄 Anyhow, I told them that in the event they need one I have a spare I can send to them and I said it's unlikely both units would have failed in the two pumps. The guy on the phone agreed and we are going from that. Let's see how this pans out....

Damn I'm so glad we have a company like Diesel Central up here.

Is it "A Long Way to Tipperary"? Sorry :).

Hahaha.... Good one GU2. Yes a popular song and a nice one.From me to Tipperary is around 150k which is not too bad. Let's hope it stays around the 850e mark. I have learned a lot about trying to make profit through vehicles in this project and so far I can say that the labour and time would out weigh any sort of profit or sense in doing something like for the average person and only for me doing it myself it would NOT pay at all. I can see why people who wouldn't have the means or knowledge to decide to scrap them though at this stage of the project every euro spent is just making it less worth the trouble.Hopefully the pump is the last of the expenditure in this project but I'm afraid until it's started and driven I have no idea how clutch/ drivetrain is...it's a lot of a chance a project like this and it has thought me a lot, It just wouldn't pay unless you are doing all the work yourself.Tgen I still have to sell it and it won't be cheap with a new pump fitted. So far all the messing with the pump and fitting/ removing alone has already consumed a hell of a lot of hours.And that's not including all the other little jobs done and left to do

Video as promised of two outer components related to the timer pistons. These are part of the timer pistons basically a valve on a spring that allows timer piston to move in and out.The main piston itself is further in the pump inside where these valves fit but this part is impossible to access without a full strip down of the pump. However, for anyone getting VP44 problems everything i have shown in the past is VERY worth doing even if only to clean and make sure they look in good order. Assuming you are a handy DIY mechanic.The amount of grit and crud i found in this area of the pump was mind blowing.These valves here in my vid as I say that are part of the timer pistons assembly, i am thinking now that when it failed it may have caused another failure within the pump elsewhere because changing and using the better valve recently for me didn't bring back my high pressure flow when i refitted my pump! For any here following my thread will have read the pump didn't end up working for me so going back to the issue here in this pump,I am thinking when this valve for timer piston started to get stuck another part of the pump had a flow problem. This whole timer piston assy is responsible for flow to the rear of the Injection pump so i assume in the past in this pump when this little piston seized up it caused a lack of flow to the rear part of the pump (Rotor) when it seizes up diesel can flow too much or not enough,which was the case here in this pump! By the way this was the cleaner looking of my two pumps that this bad valve from timer piston came out of!
Note, when I first recorded this vid I wasn't aware that more of the timer piston assembly still remains in the pump body hence why I am calling them timer pistons in the vid because I didn't realize it at the time BUT funny enough they are only part of the timer piston assembly but in fact these little valves work like small pistons too... A little confusing I know but they are as I say key parts of the timer pistons too.

Just a fast update here. The diesel specialists got back to me with a price of 1500euros. They said the pump needs to be sent to uk for an exchange unit as they are out of stock of parts and it's easier for everyone involved to do it this way 🙈 I wasn't too polite on the phone and told them to return my pump ASAP. So it looks like off to my own diesel specialists I dealt with last year. They said send it and it should not be a problem. Quoted approx 800e! Let's see how this goes... The specialists who just returned my pump to me in Cashel Tipperary said all Bosch prices are gone up so they are just sending pumps to uk now on an exchange basis. 🙄 Why wasn't I told this before sending the pump🤔 looks to me when they saw ESC tampered with they couldn't be arsed as it might cost them too much!! I was told all those elecs should be changed anyway, ohh and they also said once the pump was opened previously they don't want to really bother. Sounds like a load of crap to me and they wanted a handy repair job.Anyway, let's see how it goes with the company I dealt with last year. I'm sending pump away Monday morning.A lucky thing I'm not in a hurry with this project! Ohh and on a side note, I picked up myself another rare set of 22" super rare Alloys a few days ago and stuck them on my own daly driver. Wow, it drives and pulls so much better with these monster rims! 😂 Great acceleration... I have my other wheels for the snow!

Better post a pic with your your 22" wheels on.

The guy I bought them from said they came in from the states. I had a little work cleaning them and polishing them back up but happy with the results.Shame I didn't take a before pic though.They were dirty from sitting in a shed.

Pic there above delivering firewood to a customer in limerick city. Honestly guys and I mean this, it fixed a lot of drivability issues in the Patrol. Wayyyy faster up through the gears and pulls better in all gears. I think though it could put more strain on IP because the larger wheel and speed sensor signals say very loud 'Inject more fuel' 🤣 I don't mind, it's something different and it's not like I race the engine all the time anyway...

It is amazing what a difference changing 'unsprung weight' makes, from my days of driving and building race cars I know that every Kg you take off rotating unsprung weight (the formulae does go a little deeper with types of suspension and ratios), is like taking 10kg off the body/chassis. even going from my original steelies to my alloys years ago had a minor but noticeable impact.

I have no idea what top end drive is like yet past 120kph as I haven't tried that yet but it pulls very good up to it. To be honest I thought it would be crap to drive but it's the opposite. The IP does adjust fuel output on these for to compensate the extra load per rotation of the larger wheels. It's a very interesting thing to experience how it drives.
