Title: Stud came out instead of nut coming off?
Post by: Carolyn on March 6, 2018, 15:29
I noticed Schnazzle needing studs for his chain tensioner.  This also often happens to exhaust studs.

Tip:  soak stud with nut on it in kerosene for a few days.

They then tend to fall apart.

Saved many a stud this way.

Everybody should keep a litre or two of kero around..

Kero can be found at airfields and at farm supplies.

Good tips. I'm just going for replacement as they're just little rusty nuts :)

When I fitted my Turbo manifold I went with stainless studs and aerotight fastners as I heard there has been issues in the past with the manifold nuts coming loose on turbo'd cars

After 3 days worth of dosing with WD40 Fast Release penetrant did nothing to my bright orange chain tensioner nuts, I'll give anything a go
