Really? Are you sure that - like most overly tight sump bungs - they're not simply tight because people don't spot the taper when they tighten them with a windy gun? (I kid you not, I've seen someone doing that)......
I'm not saying you're mistaken, but have had my share of LR engines apart over the years and have yet to observe such a funnyosity.

I always thought that the only LH threads anywhere around a Land Rover would be the wheel studs & nuts on one side of certain, heavy-duty specialist LR-based vehicles on 101 chassis and the bolt that holds the fan clutch to the pulley on models with a viscous fan.

Im pretty sure rebuilt enough of them now. the early 2 lt engines had left hand thread but it varied across production. i have seen some 2.25 with left and some with right.


It appears my drain plag has been over.tightened....oh joy.


What are the thoughts on the large cloud of.smoke i.managed to get when i took it to high revss

Same comment as before - if you haven't actually had a proper drive yet, don't get to too worked up about it.

Hi everyone

thanks for all the comments. i am in the process of changing the oil etc which i have to say was horrible and very smelly. the drajn plug had been air gunned in and i have had to remove and redrill out the plug to sort the issueout. the oil filter was also in a very poor state with a substantial amount of sludge in the top of the filter housing indicating the oil had been jn the car for some time. which brings me to an important question. knowing the volumn of sludge in the engine i oil filter is it worth assuming that the sump will also be clogged up and as such is it best to remove the sump and flush or is there a flushing agent i can use without removing the sump. i was thinking of using some cheap oil then flushing it out using that. then cleaning out this oil and with it gunge. then refilling with fresh oil.

Best regards

lee

If it's not too difficult to get the sump off with the engine in place, then I'd remove it, give it a good clean and clean the oil pump strainer.

From experience I would resist the temptation of using flushing oil. It runs the risk of blocking up oilways with dislodged deposits which could cause all sorts of problems, the common ones being non working pressure transmitters, noisy valve lifters and even blocked crank jets.
Some favour tipping in a couple of litres of cheap oil in after the old oil has drained down - this is not the same as running with flushing oil and just helps to shift the dregs of old oil from the sump. This will be almost as effective as removing and cleaning the sump

Seconded.

Thirded on both counts.
