Simple cure ! I hadn't torqued down the rocker shaft sufficiently , not having a torque wrench delicate enough to measure 5nm I then could not gauge the angle torque that comes after that . Torquing it down evenly to 25nm and resetting the tappets did the trick .

Tappets were reset after new ( built up ) head installed . I'll check on the dump valve tomorrow .

Hi , I've put a new cylinder head and gasket on my Defender , initially had problems with getting the injectors properly clamped down , sprays of diesel shooting up from the head , took several starts before I managed to sort them all , that's done now and it starts and runs well but I haven't...

No, I'll return to it tomorrow and have a go .

Hi All , I put a new cylinder head on my 300tdi , there is a threaded hole half way down along the top of the head on the exhaust side . My old head had a bolt in it but it sheared off when I tried to remove it . Just need to know the thread size please .

Funny you should say that , just tried it and of course no go . Any tips to get it going ?

Actually I just got it , pressing the plate well in and keeping it there with my thumb whilst tightening the nut did the trick .

Hi , I've been trying to tighten down the injectors into my new head , managed two of them but the other two have a little play in them . Studs are fully in and the right way round ( I think ) with the flat bit at the bottom of the thread facing upwards . Clamps are installed curving downwards ...

Measured protrusion with dial indicator today and highest reading is 65 on the dial . So that'll be a two hole gasket . To ensure pistons were absolutely level with the deck I raised them until they just made contact with a straight edge and the 0.05 part of a feeler gauge would not go across...

Well , I finally bit the bullet and took the head off . The gasket was clearly burned between 2 and 3 , carbon in the same area on the block and head , Two of those little triangular things in the head were very corroded , and there is pitting towards the sides within the " big circles " of 2...

Will do .

Consensus of opinion among local mechanics is head gasket or cracked head .

Put the garden hose to it yesterday , water flowed freely in every direction , made no difference . Local mechanics are puzzled , I've a few more lined up to come along and scratch their heads ..

I've already put a hose to the heater pipes and it flowed freely and clean . Does it matter which hose goes to which port on the heater ? I've tried it both ways but it made no difference . Looks like my next move is to drain my new coolant into a clean container ( third time now ) and get the...

Thanks for reply , the engine gets hot to the touch so I assume the coolant inside it is also hot ! I'm pretty sure it doesn't circulate for long . If I start the engine with the thermostat housing or rad bung off , then the coolant splurges out all over the place , so I reckon that's it being...

Hi All , Some of you may have seen my thread from a couple of months back entitled "300tdi Coolant Gushing " , out of the expansion tank that is , with overheating and no circulation or warm air . I never managed to resolve the problem , but decided to finish the restoration and come back to...

I'd be over the moon if it just needed bleeding . It had been lying in a yard for six years before I rescued it . Two core plugs were missing and who knows what abuse it got , but when I replaced them it started straight up and drove with good power and no smoke , but as I reached home the...

Hi All , Now that I've finished faffing about with the timing belt on my project 300tdi 110 , I decided to fit the new radiator , hoses , and thermostat . Filled it by the book , started up , and ran it for a few minutes with the expansion cap off , I thought it might help with releasing any...

The gear is now in place , I wound it in with the pulley nut . It now sits close to the casing and just behind the key .

It's exactly the same as the old one that came off it , which now also blocks the gear wheel ..
