What we do when rebuilding all BMW N47D20C engines
The engine is stripped to bare component
We then put all parts including the block into a high pressure cylindrical wash at high temperature with cleansing chemicals,this removes all carbon deposits and debris from previous failures.
From this stage the Cylinder Block is re-honed. Some may need to be re-bored & some may need re sleeving this would be at an extra cost.
The Piston Rings are then changed.
Connecting Rods are then checked.
The Crankshaft is then checked and polished.
After this the main and big end bearing shells are replaced with kolbenschmidt bearings.
The oil pump is then checked and reconditioned where possible.
Cylinder Head is stripped down and checked for wear, pressure tested for cracks and then face machined.
Valves and guides are then checked for wear.
After this valve seats are machined.
Refaced valves are re cut, new stem seals are fitted and the head then vacuum tested.
From there we refit the rockers and followers.
The Camshafts are then checked.
The engine is then reassembled with new Elring gaskets and seals etc.
BMW N47D20C TIMING CHAIN FAILURE
BMW diesel engine & timing chain problems.
Timing chain failure is becoming more of a problem for lots of BMW owners this has been aired on BBC's Watchdog. 2.0 diesel engines produced between 2006 and 2012 seam to have a design problem affecting the timing chain. The engine timing chain which is situed at the rear of the engine seams to be very weak causing the chain and or links to fail.
BMW timing chains snap on the following models 1, 3 & 5 Series, all with the N47 diesel engine range. This is also becoming more of an issue on the N57 diesel engines as well.
When we rebuild these engine we use the most up to date tensioners and guide rails we also use uprated chains, All chains are replaced including the oil pump chain.
When the BMW timing chain breaks it can cause all different typs of extended issues i.e bent valves damaged rocker shafts and sometimes even cracking the camshaft carrier which in turn slightly bends the camshafts.
All engines and gearboxes sold by Dal Jones Automotive are on exchange basis of serviceable units and surcharges may apply.
