Hello,
I am currently trying to restart an 1989 13B Serie 5 engine with my university and now I am doing a sync test to see if the sparks and injectors are firing at the correct time and order. But, while turning my engine without fuel (just with the starter), I saw a oil stain on the ground. I have found where the leakage appears (see Figure). I also saw that my OMP is stuck in 41% opening (an other student was responsible for that) and I was wondering if this leakage was due to the high amount of oil running compared to the low rpm of the engine at start ? In my manual, there are no indication about a specific torque to apply to this bolt so i am wondering if there is one and also if I continue like this, am I damaging the engine ?
This engine has been assembled and disassembled many time by different people so my concern is that some bolt aren't fasten enough.
Thank you
That connection is a flare fitting, which should be pretty tight. But if it's leaking despite being appropriately torqued, I would inspect the sealing surfaces for any possible contamination or damage.
Hello,
Thank you for your quick response. The previous guy how mounted the engine didn't tight it at all !! Now it is fixed.
The 41% is because our ECU imposed by the university can't control the oil system so we have a device that compute the opening percentage with regressions. A hole story ahah !
