Repairing oil sump plug - type 4 - options

Discussion in 'Mech Tech' started by Fil6, Apr 24, 2016.

  1. so while the engines out, I thought I would tackle repairing the sump plug.

    Last year I tapped it out from m14 to m15. But the plug does not tighten up enough or the threads are twisted or broken.

    Does this call for helicoils? Thing is I don't know which ones to get? Do I tap out further to m16 as m15 are hard to find for a reasonable price.

    Are there any other fixes? Timeserts?
     
  2. I've the same issue, sump plug was hand tight when I went to do an oil change so tried to sort the issue by retapping. It's worked with a little sealant but needs fixing properly.
    I've been told about helecoil and I think you get the tap with the kits.

  4. I used some PTF tape around the bottom of the thread and a new crush washer. So far so good as it has only been about 50 miles since done this but no drips from the sump nut as before!

  5. @Lardy did you tap your sump case out to M16x1.5?
     
  6. So really need help. It is all too confusing and potentially very expensive. What is it about the small jobs always becoming the hardest?

    Option 1 - tap out the existing 15mm hole to m16 and fit a new m16 sump plug - cost around £30 for tools and plug.

    Option 2 - purchase a v coil 15mm sump repair kit - cost around £30 for the kit

    Option 3 purchase a m16 helicoil kit and m16 sump plug - cost around £60

    Option 4 - fill it with playdoh and hope it doesn't leak o_O

    Option 5 - whing and moan, then whing and moan a bit more - time passes and the engine is still in the garage without a sodding sump plug! Summer has been and gone, bus goes on sale for the price of a sump plug repair kit - wife gets the hump, kids don't want to know me, I turn to drink, get divorced, become homeless and live the rest of my life out in Primark door front, until I die at the age of 37. :confused::D

    Option 5 is a bit extreme - I would never get the price of a sump plug repair kit for my bus :D

  7. Option 1-2 or 3 , do it once and properly .

    The consequences of losing the sump plug whilst trunddling along would be catastrophic :eek:

    :hattip:

  8. ^Whs^
    Fixing something harder to take repetitive sump plug removal might give you reassurance it won't happen again or mean there's something else to give way.. but both would work..

    Ps avoid 5 sounds rubbish
     
  9. I've repaired them using a timesert before and then fitted a M14x1.25 plug
     
  10. Thanks Paul. But timeserts are madly expensive if you don't already have the kit.
     
  11. Ermmmm, yep, I know it's a coarse thread and needs a fine thread. It's all good, I'll be sorting it eventually :oops:
