    Yes I believe so. Number 4 cylinder is black.. evidence of unburnt fuel due to not enough air getting in. Would explain why my mpg has been shocking as I believe these engines compensate for weaknesses so throwing more fuel in to keep up with the power required. I always thought it was a little...

    Thanks, been through this and nothing found, think what ever it was that caused the marks was previous to this issue. Torque converter and flexplate all good. Bolts all tight.

    Update: New camshaft, followers etc installed. Heads we checked and way out so have been skimmed. Old camshaft is a joke.. no wonder I was lacking a bit of power when towing, although I read these v8's are good a compensating for failures... This one must have been compensating well...

    Well a 3 y/o and a 13 month old don't add up to a lot of time in the garage... Been down to have a look it today. Definitely knackered.. follower on number 4 cylinder is hardly lifting at all. Number 2 cylinder is nice and black... The rest of them are lifting varying amounts. Cylinders look...

    What full recon engine? I'm going down to see it tomorrow and discuss way forward. Looks like the oil feed on number 2 is blocked up or has been. That's where the worst part is. Couple of worn followers. Good news is the rest of the engine is looking ok. Pressure and seal wise. Expensive...

    Well the results are in. Camshaft has had it. Looks like oil starvation. Blacken around number 2. Looks like been dumping fuel and not enough air. Going to see it tomorrow. So new camshaft and followers etc. What shall I put in? Stock? Upgraded high torque?

    Well the puzzle continues. Inlet manifold off, camshaft, followers, valves all check as much as possible and all good. No Cylinders pressure tested to to point where the engine try's to turn over and no problems. Next options is either possible timing issue so front engine strip down and...

    Well its in with local LR specialist now. Their initial thought is it's a misfire, caused by what they are not sure. There is a cracking noise coming from the passenger side of the engine when you blip the throttle when car is stationary. This is the noise I heard. Currently the following has...

    I'm not loosing any coolant and no oil in coolant and not overheating. Engine oil looks clean. Will try compression test today see if any issues show up from that. What sort of compression should I be getting?

    Ok flex plate looks ok. Can't see any cracks etc. Marks on the torque converter could be old. Nothing in the bell housing loose anyway. New v fan clutch and water pump fitted today. Wobble has gone on the fan. But knocking noise still there. Managed to stethoscope the engine and appears...

    I'm thinking possible bolt come loose and rattled around the housing causing all those marks? Also what is that that is actually marked?

    Thanks for the offer, I ordered OEM one from island last night as not happy with the play in it anyway so need to replace it. Just hope it hasn't damaged the water pump. Shall see if it is the cause.. Will remove the bell housing inspection plate today and see if the flex plate is ok.. Is...
