I can't see any harm in that at all. Polytetrafluoroethylene (PTFE) is non reactive IIRC, so there should be no problems with contamination etc.
 An engine to TDi for!

ptfe tape in plumbing is generally used on tapered threads to seal any imperfections in the male and female thread faces, most plugs on cars have parrallel threads and a copper washer or recessed o ring to perform the seal, on a parallel thread the ptfe tape wont do much and will probably get pushed off the plug as it goes in the hole. If it wasnt fitted new its probably not required and if you have a leak past the treads a proper sealant like the ones loctite do would probably be more appropriate. There is also a chance that as PTFE reduces friction you could end up over torquing your plugs DEFENDER 90 TDCI XS,
I hope everyone is well and your land rovers make you happy |

if I'm not mis taken the transfer box is a tapered thread so perhaps this is a good thing you've used so ptfe.
its what I was going to do but the dealers replaced the plug and it seems to have sorted the problem I had. |

I've stopped a few leaks in my transmission with it before.

I always PTFE the filler/level/drain plugs on my customer cars. Never had a problem, as the plugs are rough & tapered anyway, but you have to be rigorous in removing all the old thread and re-wrapping it with new when you take the plug out, otherwise the old tape gets everywhere inside the housing.
Advantage of taping is that the plug is easier to remove at the next service point, which means less likelihood of a damaged thread. The taper plugs seem to be "sticky" enough when they are done up, not to drop out on the road. Roads? Where we're going, we don't need roads. |
