This was German magic, Liqui Moly can revive anything and this is I am writing after expereince, best example is of ceretac, I was doing noisy 70km/h top speed from Lahore to Isloo, and after putting this inn I did mid 80s and touch 105 on road to Jalkhad, at-least 20% noise reduction (Diesel Engines) and it was running friciton free.
Best picture of Liqui Moli :), and friends you should smell it before putting in the engine, I can bet you will be tempted to drink this
