Sump plug problem

[MKS]

my 987.1 has a 8mm hex sump plug which I can’t undo. The hex is burred! Has anyone got any thoughts on how I can unscrew it without damaging the aluminium sump?

This is a difficult one
Balance the cost of extreme damage against getting it done professionally

Even a Porsche Centre will only charge an hour - But you do need to get affixed price

Obtain a new Plug

I would certainly try a pair of WAter pump pliers May help if engine is warm.

Perhaps give it a sharp tap in the right direction with a hammer and chisel BUT ONLY ONCE

Try a tight fitting star of torx bit in the hole - usually does it for me when they are all rounded inside.
thanks

Weld a nut on it, then use a spanner to undo it - simples! []

Probably need a garage to do this but GREAT IDEA

Should be a quick cheap fix - Get them to loosen it and retighten and do the job at home

The simplest solution is usually the best

Thanks everyone, plug cake out with an easy out drive. Can anyone tell me the oil capacity for my 987.1 3.2s. The manual says 7.75 litres, I’ve put that in and left the car for an hour and it’s still registering as empty on the gauge.

I'm surprised that 7.75 litres doesn't register any level on the gauge. If you have changed the filter as well most forum users quote 8.25 litres as being required to reach one segment down on the gauge. Is the the gauge flashing alarm or just no response? Since you clearly have plenty of oil in the sump it would be safe to drive (oil pressure showing normal of course) and try measuring again later.

Thanks Geoff, I left it another half hour after my message last night and looked again at the gauge and the oil i'd measured out from the 10 litres i'd bought, I then realised that in my nervousness not to over fill it that I'd only put 6.75 in not 7.75 so added another litre and the gauge read almost full. I'll fire her up tonight for a run out.

I'm with Geoff on this Melvyn.

Adding 7.75 litres is more than enough to have confidence in starting the engine and getting it up to full working temperature, at which point you can check the level again.

Edit: Ha!! Simultaneous post there Melvyn.

Check as you said when up to temp ..better underfill than overfill .

Hi, well all I could suggest, seeing as though the head of the sump plug sits recessed into the sump, you could Araldite the Allen head into the sump plug,let it go off then carefully try to undo the sump plug, or you could drill a blind hole or use a drummer to put a slot in the sump plug and then tap it around with a centre punch or a small chisel, regards Del
