Fitting a new maf sensor & PCV filter
I have been having issues with my 2.0 diesel tourer for about 10 months now, if i really think back not extra special MPG always feeling sluggish but the power was there if i booted it just that nice smoothness missing in the low revs and speeds, oh and the heart pulsating feeling of pulling out from junctions and roundabouts it is only over the last 5-7 weeks that the car as been surging, ie losing power as though it was going to stop cut out only to kick forward if i pressed the gas pedal a bit more cruising at say 30/50/70 you would still get the stopping dead feeling then surge forward.
Asked on the forums and read up a bit about this and was given the answer its the MAF so at our recent Nano meet on the 11th March i was given the chance to get her on a T4 session with Duncan :hail: to check out any faults and sure enough the MAF was reading wrong unplugged it at the Nano took her for a drive seemed to pick up and feel better, so new MAF needed purchased one from Eurocarparts (not cheap but a must have )below is how i fitted the MAF and the PCV filter at the same time enjoy Arctic.

PCV filter fitting
Carrying on from the fitting of the maf sensor i decided to change the PCV filter at the same time even though i only changed it 8-10months ago at only £8.99 its worth it in my eyes anyway so here goes.
To replace the PCV with out removing the fuel line and clips first unscrew the three retaining screws then disconnect the injector wiring plugs and move the harness to one side follow the pics below. Fig one remove the three screws 5mm socket worked for me on the star screws. https://i.imgur.com/VqUV4wal.jpg1 Fig two screws removed from there fixings https://i.imgur.com/p2ou9F1l.jpg2 Fig three unplug the injector wiring harness four just squeeze on the tang, you could use a small screw driver to open the tang and pull off. https://i.imgur.com/fG1HgjRl.jpg3 Fig four set harness to one side out of the way https://i.imgur.com/AvQJu0Rl.jpg4 Fig five/six unscrew the four Allen screws so you can remove the PCV filter valve housing https://i.imgur.com/WCVqcCRl.jpg5 https://i.imgur.com/0qPfvMzl.jpg6 Fig seven remove the filter housing by lifting and twisting toward you or the front of the car carefully no rush it should come away nicely without having to unclip any fuel return hoses thus not braking those little T junctions https://i.imgur.com/6NRiDgel.jpg7 Fig eight clean and check the rubber gaskets seals or change for new ones. https://i.imgur.com/aPLlXxKl.jpg8 Fig my old and new filter, this is only 8-10months old still soft a wet not hard so in theory did not need changng but hey why not. https://i.imgur.com/tJ6BaZNl.jpg9 Fig then clean inside the valve fit new rubber O- ring https://i.imgur.com/CJObz7cl.jpg10 Fig eleven fit new filter push home over the O ring and pushdown the plastic holder https://i.imgur.com/XR77BjJl.jpg11 Fig twelve refit the PCV valve by tilting reverse of removal carefully again no rush making sure not to disturb the fuel return hoses. https://i.imgur.com/MiCTJtYl.jpg12 Fig thirteen refit the four Allen screws corners first then the rear and front https://i.imgur.com/X8B8U5ul.jpg13 Fig fourteen replace or fit new air filter again i fitted new one even though it did not need it, why not i am fussy. https://i.imgur.com/rKHzDb2l.jpg14 Fig fifteen refit the air filter cover starting at the right rear corner this can be fiddly once started do not screw home as the others have to be lined up. https://i.imgur.com/JROdkk4l.jpg15 Fig sixteen fit the others there are five remember two at the back corners and three at the front top. https://i.imgur.com/EV8mkHwl.jpg16 Fig seventeen refit air intake pipe push fit https://i.imgur.com/nzSSOBil.jpg17 Fig eighteen refit two screws holding the air intake pipe housing https://i.imgur.com/vcwP8Pfl.jpg18 Fig nineteen/twenty refit the engine cover three bolts tidy up your tools wash hands take the car for a nice drive check out the smoothness and new power https://i.imgur.com/rqhG3Ndl.jpg19 https://i.imgur.com/oZ4CQ9Pl.jpg20 Jobs a good one happy motoring again :clap: http://www.ebay.co.uk/itm/LAND-ROVER...72.m2749.l2649 Photos re-instated 22/11/23 time 02-06 |
