leaking sump
« on: 29 March 2010, 11:53:56 »
HI

IVE GOT A 2.5 TD AUTO OMEGA BMW ENGINE 1999. THE PROBLEM I HAVE IS THE SUMP PLUG IS LEAKING. I LIVE IN THE BLACK COUNTRY AND I HAVE TRIED TO FIND PLACES THAT CAN HELICOIL IT BUT THEY ARE EITHER UP NORTH AS IN BRADFORD OR DOWN SOUTH AS IN SOUTHHAMPTON. CAN ANYONE GIVE ME A CHEAP CREDIT CRUNCH SOLUTION TO THIS AS I DO NOT WANT TO HAVE TO PUT A BRAND NEW ONE ON AS I NEARLY FAINTED WHEN THE DEALERSHIP TOLD ME THE PRICE. I HAVE TRIED TO FIND A SECOND HAND SUMP BUT THERE ARE TOO MANY OMEGA LOVERS OUT THERE AND THEY DO NOT WANT TO LET THEIR CARS GO THE THE CAR CEMITRY. MANY THANKS IN ADVANCE TO WHO EVER CAN GIVE ME A SOLUTION.

REGARDS

The BMW sumps are rubbish, always strip.  You could buy a helicoil kit, but would imagine most engineering firms would be more than willing to do it...

Isn't there the material to tap out to a bigger size?

Yes, but it will fail again.  Do NOT underestimate the crap quality of BMW components. Helicoil is the fix.

It must be bad then if a Helicoil is better. I've never had much faith in Helicoils, they have a tendancy to wind out.

I have tested the 'knock the sump plug out at 80mph' test - Believe me, helicoils are superb ::)

MDTM used a spark plug helicoil kit on my old tractor (now Squealeys), and a Peugeot sump plug (Pugs do a sump plug that is same diameter and thread pitch to spark plugs)

Had the same problem, drilled it with a 12mm drill, and fitted an M14 x 1.5 plug. That was about 4 oil changes ago, no further problems.

HTH :y,

I used the 12mm drill, rather than the 12.5 before tapping the new thread which allowed a snug interference fit for the new sump plug. :y

that's the same as a regular Omega & Astra sump plug then .... I think. I 've a spare Omega plug,  an almost stripped Astra sump pan but no suitable tap to clear the Astra sump. I'm sure I decided the plug was M14 x 1.25     I'll dig my thread gauges out tomorrow.  :y

Pretty sure they are 1.5.....the 1.25 is a little odd....hence why french cars use it
