Threaded Sump Plug

Previous owner over tightened the sump plug. Now I can not tighten it. It simply tightens then loosens, tightens then loosens. Never more than just beyond finger tight.

I tried wrapping it in teflon tape / plumbers tape but that only stopped the leak, hasn't allowed me to tighten it properly.

Now, can i get it re tapped to a larger thread? It is an bnr32 so removing the sump is really out of the question. Assuming it is possible, should i be fearful of metal shards making their way into my sump? Finally, do i need to see an engine builder or can most mechanics conduct this operation?

Super cheap have a range of bungs going up in size so i dont think you will have any probs getting one slightly larger.

Any spanner should be able to take care of it for you.

i wouldn't use PTFE tape (plumbers tape) on your sump plug. bits of it will break off and get sucked up your oil pickup. you could get it tapped out, as long as there is enough meat there to tap into. i don't think most mechanics would have the tap your after. if you are looking at tapping the hole out also look into Helicoils (thred repair).

1- Try a new bolt.

2- If that fails get it re-tapped.

Does anyone know who sells a quick release valve for this purpose?It would be good to get one fitted

and stop this sort of thing ever happening in the first place.

Good luck and hope the new bolt will fix your problem.

Quick release plugs / tap thingo's really are not a good option mine had one on the car took forever to empty the sump and stripped when removed, bugger.

when tapping a hole swarf comes out as part of the cutting action so shouldnt go in'

thats all we did and still good many changes later with a standard super cheap type sump plug.

As long as the mechanic has the required tap size any mechanic should manage this one and from memory there is a fair bit of meat there to tap

yep mine was rooted too and had to be drilled out then a new thread cut in. all this can be done in car and no metal will go into the sump. but you will end up with a bigger sump plug obviously and sadly for me the dude doing it chose a bloody imperial bolt so I now have one imperial bolt on my car... sucks :glare:

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
