Coolant loss --> ?? K-Seal=Fix??

[fowens]

My Techno-Violet Dinan M has a persistent internal (!) coolant loss, about 1 liter every 400 miles. Multiple checkouts found no leaks... must be going out the tailpipe. ouch. Only 111k miles. In all other respects, performance is top notch.

Now I hear that K-Seal by Solv-Tec can provide a quick permanent fix. My Bimmer-specialist mechanic say 'Why not give it a try?'

First -- anyone out there used this already?
Thanks! FreDad

have you pressure tested the cooling system?

have you performed a compression test?

i think you may be jumping the gun.

i have yet to see one of those block sealing products work without clogging the heatercore. not worth it. i can give you that as the first "why not."

+1 2nd opinion is a good idea - pressure test for sure.
