Hi all, just bought my 1st Porsche, a 2000, 3.2 S - yesterday. Did a bit of research before purchase but today, on YouTube, I watched a clip about buying a used Boxster and to NOT buy one that has a 'mayonaise' type residue on the underside of the filler cap.
I then went straight out to check my car- which I purchased privately- opened the cap and saw a thin film of a white substance under the cap and on the filler tube neck. It was a very small amount.
Should I be very worried? Advice please!!!
Going to immediately phone main dealer tomorrow morning to book in for it's 60,000 service anyway but all replies appreciated.
Hi
Its nothing to worry about...
Its called "mayonnaise" and its just moisture caused by either short runs or lack of use...
All you have to do is take it for a 20 mile blast on open roads and it will vanish...
I was a race mechanic for many years and whenever its a blown headgasket there are TONS of the stuff....several CUP FULLS....and also oil in the water...
So don't worry, just give it a blast and all will be ok
All the best Brett
