Omega Owners Forum - Exhaust Studs

Steve Brookman Intermediate Member Offline Posts: 283 Blackwood, Gwent Gender: Drives: Elite 3.0 Estate, Range Rover	Exhaust Studs 11. Feb 2010 at 07:47 Hello all, Am going to change the exhaust on the better halfs Elite estate. Looking at it the exhaust is joined to the front pipes with studs. More than likely I'll have to cut and drill them out. Are they relatively easy to drill out? Will have the car up on car ramps at the front. Any tips appreciated. Thanks Steve

Mine were a total nightmare.

The previous owner had snapped three off in the head (amateur did not use plus-gas) and just fitted the manifold with the remaining bolts so it blew the gasket and leaked like hell.

They had to be drilled out and replaced with new VX ones; total cost £190 inc studs and vat.

See sig link Thumbs Up!

Best advice-ask someone who has done this before to help, use plenty of plus-gas long before removal, tighten carefully Thumbs Up!

They are bolts that screw into (or rather shear off at) the front cat section. Its worth using Plusgas on them, heat and being very very careful winding them out. Even so they may well still shear.

Ironically, despite their willingness to shear, they are bloody hard. I used a cobalt bit (8mm) last time and that did the trick.

Feb 2010 at 20:59 I was as careful as I could - penetrating oil, heat, ground off the tip, etc. Two still sheared... Just be ready to drill them out and don't bother tapping the hole just put a bolt through and use a nut. Next time if the bolt shears it will just fall out.
