Thread: Oil leaks sump fix

What engine is this on , a VM diesel ?

0.374L/100km of oil

Geez, I have to hand it to you for exactitude!!!!
There would have to be at least .004litres caught in the bolt threads.

I just let mine leak, but as it only leaks 0.0542L/100KM, it's not so much of a hassle for me...

Sure its not leaking further North? - and dripping down onto the sump via the rear axle ?

Maybe a differant kind of gasket ? More goo of another brand ?

Or;-

- Just replace the engine with a (boring) japanese one...

how tight is your oil filter

When I rebuilt the 4.4 for my last RR, I was determined that the sump was not going to leak. I cleaned all mating faces with thinners, then applied a thick bead of threebond sealant (around $75 a cartridge) to the sealing face of the block (this was with the engine upside-down on a stand, but you could do it with the engine insitu by applying the sealant to the sump instead), then rested the sump in place, inserted the bolts but did not tighten them. I tightened the sump bolts down enough so that the sealant was still at least 2mm or so thick between the mating faces, then left it for an hour before doing the bolts up neat. This leaves a thick gasket of sealant between the mating faces. It has never leaked a drop in 115,000km.
For several years I've been applying loctite hydraulic thread sealant to my sumpplugs when refitting them after oil changes. This solves another annoying leak area.
