    Sump Drain Plug torque

    Apologies for this question; I've tried search (believe me!) but no luck...

    What torque should be put on the sump drain plug of the Isuzu 4BD1?

    The 4BD1 motor is a fairly tough piece of Japanese engineering, so my recommendation would be 1 click of the elbow, and if it weeps, give it another.

    If your going to the trouble of torquing the bolt, if it had a copper washer than its best it anneal the copper washer

    Les is right, and the reply from Weeds would be good advice IF the drain plug in question had a copper washer as opposed to a plastic seal. But neither of them are telling me what I want to know.
    So, perhaps this question was more complicated than I thought. (Or something...)

    Firstly, is a fairly substantial plastic sealing washer normally fitted to the sump drain plug of the 4BD1?
    If "no" to the above, see question at top of thread. And, if "yes" to the above, see question at top of thread.

    I have never torqued up a sump, gearbox or diff plug, I normally just nip them up fairly tight so there is No leaks.
    I have Never lost a plug yet neither have I stripped the threads either.

    I've never torqued anything other than head, main and rod bolts/nuts on an engine.
    I just use the right amount of righty tighty that i think the job needs.

    I dont use the handle of ratchet to tighten sump bolts nor would I hold the end of a combination spanner... Mostly I hold the spanner with my thumb on head of plug and tighten, your wrist should apply approx 25 ft-lbs which is generally enough to seal a plug... If it weaps, then maybe another 1/16 th of a turn at most... Remember, its to seal and has to be undone and done up many more times in its life, one over tighten and its life gets shortened considerably... If overtightened too many times then you either strip threads on plug or damage threads on sump, either way it will probably happen a long way from home as Murphy dont like doing things the easy way...

    Couldn't find anything specified in the 4bd1/4bd1t automotive engine manual. Has a table of bolt alloy type by diameter with general torque recommendations where not otherwise specified.

    Doesn't exactly match the question at the top of the thread and don't know the source, but 2nd last entry has 26lb/35Nm for the tubo engine (copper or plastic?). May just have to risk it on the n/a. . Assuming automotive and not industrial 4bd1

    I'm assuming that is with a new copper washer...
