of course it will you have more flow even a good working stock cat hinders performance ....this is why some street racing enthusiasts install high flow cats as it keeps the law at bay ....some just do a delete take a deep breath inhale quickly through the mouth .... then try an exhale...

of course it will you have more flow even a good working stock cat hinders performance ....this is why some street racing enthusiasts install high flow cats as it keeps the law at bay do you still have the EGR system active ?

smash the cat out is allot easier unfortunatly the td5 does not go into regen mode the cat maybe to far gone and it may of callapsed in areas if you have had dribbly injectors in the past ... raw diesel destroys these things

measure the ID of your breathing hose i think its about 19 mm but dont hold me on this also have a look into installing a decent catch can ....this can help the intercooler and intake manifold coking (even if the EGR is blanked or not )

clogged exhaust ?

all good mate but i was on the understanding that it apears the bolt has come loose at some point !!!! and yes the bolt will be removed by now as you have it in pieces LOL as for the internals of an oil pump the housing is some times over looked are you noting down any measurements ? (blue...

if the bottom skirt or ring groove on the piston is worn change the piston also remove the rings from piston and install rings inside the cylinder measure your ring gap you might not need new rings piston ring groove if the ring is to loose and out of spec or the wrong ring used can cause...

faulty maf or map sensor ? you would need to monitor boost pressure

i agree as i am using one in mine as we speak my local landrover shop DA autos warned me to stay away from them as i was shoping around for prices ... it appears he mentioned something about be carfull then mumbled the rest about a preasure difference and they dont last long in the td5s...

you can bypass the lift pump and leave it in place... an install a facet electric pump or any other cheap inline delivery fuel pump

in the first post he mentioned that the bolt has been loose at some point..... and this tells me its not loose any more ....... so this also explains other people have owned this and others have worked on it also ( lack of history of the engine ) dont be to sure about you dont think any one...

sorry i have to disagree .....@ problems at the head only Lack of oil pressure at the mains and big end journals ? Lack of oil pressure to the turbo ? Lack of oil pressure to the piston cooling jets ?

looks can be deceiving:confused: you will find that the injector spill line has its own gallery masked in your illustration otherwise number 4 fuel feed line and number 14 spill line in your illustration would be sending fuel to both sides to the cylinder head ;)

i also just noticed you took a pressure reading from the temp sensor location ....this is not a true head pressure reading due to one simple flaw.... if the gauze inside the head was to be blocked or partially blocked ....the fuel temp sensor location will still see pressure as the regulator...

test purposes by substitution swap number 5 injector into another cylinder location then test again

i drilled the top and towards the front of the manifold and taped in a fitting if your going to tig in alloy plate you could do this any where even over the core plug area

i m unsure if there a different rates in map sensors for the td5 this is not my area of work not really clued up on the td5 management system so please go easy on me mate i know for other diesel engines in my line of work they use different bar rated sensors running off a sample tube from...

i drilled my manifold to install a boost gauge for a better and true reading plenty of meat to drill and tap leave that core plug alone as they are not that thick .... not to sure how a map sensor will react as these are mostly calibrated however its worth a try or even installing a...

depending on age and mileage i highly doubt it was the 2 stroke as it never failed all 5 injectors adding in oil to the fuel you must of been trying to substitute for some issiue i have been running 2 stroke through my td5 and diesel ford focus for a few year now with no issues (i am only pro...

2 stroke and a couple of months later only one injector failed ? so how did this single injector fail? electronically or mechanicaly ? whats your tests ?... and did you have this injector tested why and how it failed ? since your no mechanic or fuel specialist .....why are you adding in...
