    ABS Sensor Wiring

    Thanks for the wiring diagram - accessed the ecu; pulled the connector and tested pins as directed. Open / Closed circuit as one would expect (Closed is 1000 Ohm approx); when test the sensor itself then do get voltage reading. Which seems to indicate all is in order - except it isn't. New...

    ABS Sensor Wiring

    3 amigos - RHR sensor fault code, but sensor itself appears OK (have cleaned it anyway / replaced, and get approx 2V when wheel spinning). Am also getting 1.5 ohm from harness at junction nearest the wheel. Thus looks as if problem between wiring connector at wheel and the Wabco unit? What...

    Further head issues (V8)

    Head polished and tested - incl valve guides checked (which are OK - presumably eliminates them as an issue). Now just need to sort out helicoils. I'd still be v interested in views on how long an insert is needed for a head bolt. Current ones (ie which failed) are 1.5D only - I can't quite...

    Further head issues (V8)

    Your prompt replies very much appreciated! Bolts seem to screw in/out easily into the inserts, though the very top of the one in "No 8" broke off when I was doing so - only using finger power. Otherwise they seem OK though I have not torqued them up again yet. Any views on length of insert...

    Further head issues (V8)

    Will get head checked again asap, but by my way of thinking if the helicoils are a reasonably obvious potential source of failure, then I should look at ensuring they are 100% right before tearing into everything else. Or not?

    Further head issues (V8)

    Update - after rather more careful study. LR Workshop helicoiled 2 of the bolt threads on the LH side - Numbers 10 and 8 if removing in Rave order ie above No 5 Cylinder. Gasket has failed badly (completely burned through) between these 2 bolts, and No 5 cylinder head is fully carboned up...

    Further head issues (V8)

    OK: LR Workshop still feel problem is helicoil and will only recommend new block: frankly not a sensible option on a Year 2000 vehicle! I've stripped out the LH cylinder head myself, with following results: Gasket is, as expected, failed (badly burned through) - in pretty much the same spot...

    Will take to my man at Landrover tomorrow and see what he says. Thanks for the inputs.

    Further head issues (V8)

    Correction! Not oil coming out of exhaust, but oily water / vapour. I assume head gasket failure number three. Given that had the head skimmed last time, and that a reputable LR Main Workshop (I certainly trust the head mechanic, who took a personal interest in the helicoiling etc) did all...

    Further head issues (V8)

    Have just been out to run afresh over things, and look at the crankcase breather (which on searching does seem to be a bit of an issue). Now see that exhaust is spraying oil out ............... Would a blown head gasket do this? Thanks Redman

    Further head issues (V8)

    I last posted in Jun, with various engine problems that appeared to have been resolved by helicoiling a "failed/loose" head bolt, plus skim / new gasket on LHS only. [The focus of the diagnosis had been lack of compression on No 5 cylinder.] All has been well for a month or so, but on longish...

    V8i 4.0 Auto "Misfire"

    Success! At least holding up well initially. Thanks for the tip about MAF - plenty of advice and comment on this site on symptoms, cleaning, etc. Gave it a good blast of Carb Cleaner; disconnected nattery for a couple of hours to see if would help adaptive reset; and now drives like new...

    V8i 4.0 Auto "Misfire"

    Encouraging to have someone who knows what he's doing give a clear prognosis! Will try cleaning first, plus try my best to check the harness. Not many Discos locally, to try and blag a quick cross-test using a good MAF sensor, but will do my best. Are these sensors ubiquitous - or unique to...

    V8i 4.0 Auto "Misfire"

    Not so fast, my friend! Since its Sunday, I've invested a few more hours reading: have disconnected MAF sensor - and low and behold an immediate improvement. Not perfect (still hunting up and down), but can now get full revs in D and kick-down operates. Any further thoughts, anyone - other...

    V8i 4.0 Auto "Misfire"

    The saga of getting my V8i Auto 4.0 (D2/2000) running properly continues. Over last 2 months have replaced front exhaust section (aftermarket cat section, but refitted old llambdas), identified failed cylinder head bolt and consequent failed gasket (repair involved helicoil / new gasket etc)...

    Disco 2 V8i - 3 Issues: Judder / tappets? / exhaust

    OK: still not back on the road - and instead of "symptoms", now seem to have found source of problem. Left hand bank compression test failed on #5; on head removal, gasket badly worn at #5. Head now skimmed etc; but on rebuild, found that head bolt between #3 and #5 would not torque...

    Disco 2 V8i - 3 Issues: Judder / tappets? / exhaust

    PS to my last: vibration on pull away and / or load is very much still there. Seems to disappear on over-run / downhill but makes vehicle almost undrivable.

    Disco 2 V8i - 3 Issues: Judder / tappets? / exhaust

    Have spent a further 2 hours in and around / below engine. Thanks for commnet on drive plate and torque converter, but that's probably a bit too much for me - and anyway (see below) whatever it is does seem to be engine related rather than drive train. Tightened exhaust manifold bolts (2...
