HI Guy's/I have just replaced the head gaskets on a 4.6 rangerover with gas conv, I had the heads machined etc squeezed out the followers etc, the engine starts fine when cold but that's it, I can eventually get it running if I disconnect the ect sensor, when I put it back after it starts I drops it's revs down to an aCCeptable level, BUT TURN OFF AND TRY AGAIN IT'S THE SAME OLD STORY, IT WAS RUNNING FINE WHEN IT CAME IN APART FROM THE BUBBLES AND PRESSURIZING, also since lifting off the ground the front sus won't rise, any thoughts would be great, Great site by the way
regards Ken

Thanks for the reply
Just for your information the problem has been sorted but you may like to know what we found for your future reference (1) broken wire to throttle position sensor ((usual RR wiring!))This also stop the gearbox from changing out of bottom gear) (2) Crank sensor intermirrent. (3) Battery although showing good voltage when cranking it was insufficient Rangies are votage sensative (4) BCM (ecu) under seat swamped with faults
when the above was sorted my customer said it had never gone so well, so all happy in Cornwall UK
Thanks Ken

Using Land Rover TestBook, ensure height sensors are operating properly and are correctly calibrated. Replace height sensor(s) as necessary and/or use TestBook to recalibrate EAS system.
Check for deflated air spring(s). Check for a leaking air spring, or a leaking or faulty air spring diaphragm. Check EAS system air harness connections and lines for damage, scoring or leaks. Air spring is not repairable. If it is leaking, air spring must be replaced.

Replace the ECT it may be faulty
