Holes with sealant on block

Hi

Sorry if this is obvious, but Im tearing down my first engine, a Discovery 200TDI

What are these 3 holes filled with sealant, one either side of fuel lifter, then one on side of vacuum pump housing?

Cheers

Cheers. Are they just casting holes? I plan to remove and reseal i guess.

Don’t know but in mine too, if you clean them out would you inspect and report back the curiosity is killing me

Will do!

Think they go straight through to the cam bearings from memory so I'm guessing they are there to machine oil galleries.

You wins

Thought I'd share the photo of my 200Tdi engine c/o Turner Engineering and prior to me building up pre-install. I remember these 3x holes filled with some sort of industrial mastik and thought at the time, that's odd. Didn't question it as it's a TE rebuilt engine.

Ooooh ... engine porn

Wait til next year as am planning on fitting an 3.0ltr M57 engine plus all the bells & whistles to the Ninety. I'm planning this as a forever keeper spec' Ninety for me and my darling gal to enjoy on long distance adventure/touring trips.

I'll be keeping all the existing Gwyn Lewis HD components + upgrading diffs, driveshafts, props, txfr box, a freshly rebuilt HD gearbox. I'll remove all the silly BMW diesel engine clogging silliness, strip and rebuild the M57 this coming winter keeping it to relatively std power at ~220-230bhp with lots of low end grunty torque. The project will give me a mountain climbing Ninety Soft Top that will sit at 80mph for hours on end.

The 200Tdi and all the new ancillaries will be up for sale as a complete package early 2025. Someone will get a very good deal and skip a huge amount of hard work.

Took out the gunk, had the metal plugs installed behind. Think i will leave the metal plugs as they are, add a blob new sealant then paint over
