2 sump bolts with stripped thread

[fenderbender]

On the "while Im here" principle I whipped the sump off yesterday as I had a slight leak which was dripping on the drive. Mrs FB made it clear I'd better do something about it or else.

Anyway I found two of the sump nuts had stripped the thread inside the engine casting, which would probably help with the escaping oil I guess.

The offending pair are the extreme front of the engine, and from memory bolt into the front cover - although I may be wrong.

Because of where they are I reckon I should be able to drill and tap an oversize thread with sump in situ as all the swarf and bits cannot possibly fall into the engine: gravity will mean they are safely collected in my hair.

Anybody done this? Any tips as a result?

Helicoil them, easy enough location and you're right about gravity

I would put longer bolts in to start with, i am going to assume you have a serp engine? quite common on these as these where designed to have studs not bolts and the threads are fairly week, get some bolts about 1/4 inch longer. 5;16 unc.

Make sure you use plenty of high temp silicone ,don`t bother with the gasket...Spread it on thick

Is that really good advice Daz did you not get into problems yourself with your 1st engine using that approach? you only need around a 5mm bead on a grease/oil free surface (1 only) and I emphasize GREASE/OIL FREE before closing the joint,me personally I prefer a good quality gasket and no silicone for the RV8 sump and possibly these to get round the damaged thread and needing to screw in deeper to find some good thread as V8 Racing said already. http://cgi.ebay.co.uk/Range-Land-Rover-V8-SD1-8-P6...

Forget the silicone Daz, No Nails is what you need - no need to bother with any bolts

All sound advice, guys. Maybe I could even try that pro builders glue called "Sticks Like Sh*t". (I kid ye not - get it from Jewsons or Screwfix). I stuck a ceramic washbasin to a tiled wall with this and it has not moved in 5 years.

Overtightening is the quickest way to an oil leak on the sump.

I wonder how many people have had a minor leak only to tighten the bolts and make it worse.

I fitted mine with a new gasket and a smear of silicone. Bolts barely more than 'nipped'.

I will let you know how bad it leaks soon enough
