200 TDI engine sump - Gasket or RTV?

Recommended Posts

Hi,

I need to replace the sump gasket on my 200tdi as it is leaking through the bolt holes. I've checked to see if they need nipped up but they are all tight.

Local Landy place says no gasket, use RTV. Others say use a Gasket.

What is the proper best way to do this?

thanks.

There is no gasket, RTV was used from the start.

Yep. Though a series gasket might fit. Should be similar stud pattern.

I used loctite 5940 iirc when I rebuilt my 200TDi. No signs of leaks on my sum or ladder frame.

It'll leak.  Far better to use RTV like LR did.

Not leaked in over 12 months yet, what I did find with rtv was sump is soft around the bolts so can push the rtv out so had minimal around bolts which is why I tapped the high spots down and tried a gasket

Did you let the sealant dry for a few minutes before fitting the sump, Tim?  Few do, but RTV is supposed to be let semi-cure before fitting the parts to prevent it from being squeezed out of the joint.

Yes. I usually apply to sump then clean block and a cuppa. 

Even tried the vag sump sealant thank sticks like mad. 

Came to the conclusion the sump was slightly distorted and was soft around bolts.
