yes, have now ordered elsewhere delivered three weeks ago missing a set of head bolts were cheaper than my normal sources going round in circles have opened an ebay case today

So long as they have no tracking number you will get your money back.

Hopefully mate learned my lesson maltings, paddocks etc from now on

I only get the cheap metal ones from Toolstation etc
They are pretty good, and you can treat them like crap.

The pack out stuff milwaukee/dewalt is great but mad money for diyers.

many thks for the heads up

indeed, stupid money those pack out boxes , nice stuff but certainly wouldn’t pay the amount their asking for

did also buy some of the Stanley deep box organisers for screws , got the ones with the metal catches , dewalt virtually do the same as the Stanley but more expensive

thks again mate

Yes, but it's a vicious circle i have to buy more projects to pay high tax lol. Have seen some metal shelving but just don't have the space at the moment, bolts still haven't come going to order elsewhere looks like the motors not going in this weekend

sorry to hear ur bolts haven’t arrived yet, always the way when u try and plan ahead , see you’ve ordered elsewhere

indeed ref storage , have found this company very good with a good range , used them multiple times, quick delivery plus have some decent second hand bins , this was the place I got the blue drawers

Hope that helps buddy and all ur bits arrive sooner rather than later

Thanks mate have re-ordered bolts, cam bolts turned up (maltings) today so am fitting fuel pump drive and belt, having a day and probably evening sorting out parts getting ready to get the jag in next week or two. Up to 06 the fuel pump has a diverter rail, from 07 the common rails are linked direct to pump. The plugs are also different lucky I marked the looms lol still, sussing out what bits can be used from a jag going to start cleaning block tonight can't lift it out of wheelbarrow on my own

Hooray replacement bolts arrived yesterday fitted head and cams today fitted timing belt all these parts were previously fitted all new, did two rotations no contacts so all good, injectors also in now will continue with fuel lines and locating other parts tomorrow morning

Really chuffed for u mate that the bolts turned up and able to make some fantastic progress

must confess holding my hands up that even though I’ve built a few engines, namely on my old series 3 engine wouldn’t dream of attempting to change the belts on the 2.7 , so take my hat off to u mate

Must confess knew there was a difference pre and post 07 fuel pump but wasn’t sure of what all the differences were , assume the post 07 runs at a higher pressure so wonder if the injectors are also different after 07 , thks again for the very useful info

hope the rest is straight forward without further delays and once again massive credit to u

Ditto. Ive changed a few belts over the years without much problem but when I read of the faff you have to go through to change modern cam belts, I dont think I'd have the confidence to attempt it nowadays. I sometimes wonder if people are just over complicating the process.

Thanks mate but it's not too bad to be honest it worries me too, easier with engine out as you can see number one at the top and the pins in the flywheel heads and cams all fitted at their timing points so basically, you're halfway there, engine in you can fit the cam pins and mark the bottom pulley but this mustn't move, remembering to tighten the three cam pulley bolts on each pully as long as you rotate the engine at least twice carefully by hand and the pins go back in your good to go missing a couple of o rings, work, elbow and back slowing me down a bit. I suspect the diverter block was deemed as unnecessary that's something to look into part numbers etc hope to get closer to fitting as have sun/mon off

Your right Col I wish more people would do this stuff themselves everyone knows someone that handy with spanners I don't know how much a garage charges for changing both belts dread to think, this engine was valve timed incorrectly by a garage, I wonder if there's a bit of stigma attached to some of these jobs on this engine

Think I have read incl parts it is the thick end of a grand for all three belts/idler pulleys and cam/fuel belt tensioners, might have been main dealer prices though?
Done mine twice now, not hard at all.

Hi mate

Indeed , plus buying all the tools required , when my belts were replaced back in 2016 after buying my d3 watched 2 x skilled mechanics from the D3 forum and they done all the belts , tensioners , oil pump, water pump plus the rear fuel belt in under 5 x hours

rear belt they done in less than 30 x minutes , they had it down to a tee and very impressive

plus 1 , also heard it’s around 1k , reminds me next year mine are due again , along with another new oil pump as noticed a very small oil leak on the casing so would won’t risk leaving it any longer and for peace of mind , did have the rear fuel pump belt changed so thinking of leaving that this time seeing if it breaks all that happens is the engine stopping without any risk of catastrophic damage

Along with new Aux belt, tensioners etc , did have a new water pump last time and wondering if it’s worth changing that as well seeing there not that expensive

plus before I had my first belt changed I contacted several local companies , some advised me the oil pump never needed changing, others saying no point ever changing the fuel belt , really pleased I didn’t listen as mine was one of the early oil pumps

hope ur good mate

absolutely mate we all know issues with oil pumps I just popped in for a cuppa I have a wiring issue might need to pick you guys' brains. Here is my problem one of the engine wiring looms has no knock sensor plugs the other does the loom I am using fits this later fuel pump plug wise. The other has an extra plug for the diverter rail (earlier pump) I should have marked better anyone know? why no-knock sensor plugs am i being a Richard

starting to think pre 06 does not have them work now research later If anyone knows? please fill me in

Hi mate

funny enough I thought the early ones did and after 2007 didn’t, plse don’t quote me on that , I’ll see what I can find

one of the more knowledgeable members should be along to verify that 100%

Found this for u , EU3 engine , showing knock sensors bottom of the wiring diagram

hope it’s useful

the later fuel pump has different plugs and one extra for the extra rail, and has knock sensor wiring post 06 I think any thing you can find out would be a help jag heads are 06 think this is where i got confused

thanks, mate much appreciated will have a look after work hope it's not a full moon lol
