M50 tappet noise (E34 525)
Haven’t read all the posts so probs repeating someone but know that the lifters can make noise if:
1. The wrong oil is used. 2. The oil level is wrong. 3. The hydraulic lifters need sorting. To bleed the system just get the engine up to operating temperature, then hold the revs at 3000rpm for 3 mins. Repeat up to 10 times until the ticking goes. If the Bois persists and you have the correct oil and level, get help |
