UPDATE:
Ive discovered his car is a total lemon haha.
Then the engine swap was done in the past, the brake booster vaccume hose was cut in two spots, and rather then getting a new hose, they reconnected the old hose with slightly larger bits of hose. As you can imagine, it popped off and i lost brake booster whilst driving. I suspect similar has been done with the ac system, as it doesnt even remotely hold any vaccume.
Since getting it on the road, car has had a worsening grinding/vibration on the front right, and a faulty rebuilt steering rack, it leaks out of literally every place it can. (Will be speaking to berry motor group for a replacement).
Furthermore, its started to push oil out of the dipstick, would that be cause by the dipstick o-ring being loose?
Aside from that the cars been great, ive driven it 6000klms so far, and only been through multiple liters of powers steering fluid haha.
Note, i also stole a spoiler off our v70 t5 and put it on haha.
