I recently removed my rocker covers for a clean and coat of high temp. paint, I've put it back all fine from what I can see but here is the problem..
While the turbo is spooling I can clearly hear the turbo sucking in air (Good ol' pod filter) but I can hear a strange and unique sound similar to an air leak or soft buzzing eg. zzzzzz
It's completely diffrent sound compared to the turbo spooling.
I've checked the cooler pipes and all necessary hoses for any leaks but couldn't find anything. I noticed at high revs I'm laking power, especially in second gear.
All I can think of is there some kind of air leak?
If anyone can help it would be much appriciated, i just want to see if I can fix this problem before I take it to the only mechanic I trust which is a good hour away.
Many Thanks
