2.0 TS Balancer Shaft "Blind End" Leaks

I like to address root causes when repairing, not symptoms.

Are the blind end leaks, simply ageing of the rubber coating surrounding the steel plug, or is there typically a deeper reason for these caps to weep, like excessive endplay in a shaft?

Any other "gotchas" for the replacement process? Is it one of those applications where you can only expect success with careful use of Threebond 1211?

Thanks, Adam.

The bearings on these can wear out and fail which would cause excessive movement of the shafts.

Mine were leaking. Nothing sinister, just 20 years old I guess. Both renewed.

Thank you both. At 148000km I'd be disappointed if the bearings were flogged out; will try new end caps if available locally and "see what happens".

I am planning on removing mine altogether after I found the Balance belt snapped in the casing (was only just replaced as well apparently).

Did you see the telltale rubber dust or just notice slight roughness at idle?

New end caps sourced; naturally I found a cheaper vendor after buying them - for the benefit of local members the cheap supplier was "European Auto Imports".

Old ones were removed by 1/8" drill bit in the middle, then a tek screw rattle-gunned in, to assist with prying up. New caps sealed using ThreeBond 1207C.

Cap says Corteco, V4-399 509, the small bit says 110C NBR. So they are almost a shelf item!

Neither, Was working in the wheelarch one day and noticed a slack belt sitting behind a gap in the covers/Pully. removed the covers and found it sitting there perilously close to the timing belt.
