Engine Rebuilds by "Glory German Engines"

We have revamped over 1,000 BMW engines harmed by timing chain failure, and we have built up an intensive, profoundly fruitful engine reconstruct technique.

Fixing the cataclysmic engine harm is a work concentrated and costly work. The timing chain is situated at the back of the engine, in this way we should eliminate the whole engine and totally strip down all segments to find and supplant all harmed parts to guarantee we reestablish the engine to consummate running request. The N47 or M57 engine is revamped with altered chains, aides and tensioners provided by BMW to diminish the danger of a recurrent failure.

  • Engine Code: M57 or N57 (2006-2012) modify costs shift, costs start from £3,000

Each harmed engine is independently evaluated and relying upon harm to engine parts, and variances in BMW segment valuing, the cost might be higher. Get more info at AUTOMOTIVES BLOG.

Less expensive Engine Repair Options
