Drinking oil and compressor surge sounds

Hello guys

My asv has had sticky vane problems from a few months after buying the car. A 400 mile run at high speed would normally clear it for a month or so before it would return.

2 weeks ago the oil light came on. I topped up didn't think too much on it. Last Friday it came on, checked oil and nothing on the stick. Changed the oil last weekend and did the mr muscle fix. Car running lovely again.

Checked oil yesterday morning and its at the minimum already. I pulled the boost right angle pipe and noticed some oil around the egr.

I have also noticed a compressor surge sound since the fix, I am not putting this down to the fix as it seems to come and go prior to the fix.

Doea any one have any suggestions?
