Hi,

While I was cruising last night in my 997.1 GT2 I heard weird noise like grinding coming out from the left side turbo. When I arrived home I saw an oil spot on the Y-Pipe as shown in the picture below. The weird thing is boost still 1.4 bar which perfect and there is nothing wrong with car at all. Anyone might know what is the problem?

Car mods:
Protomotive tune
Forge DV's
BMC Filter
OEM exhaust decated

 

You should pull the outlet hose off the turbo (the one going to the intercooler). See if oil comes out or if it's wet. If it is pull the air inlet to the turbo to see if it's coming down the inlet into the turbo. If not you may have a seal starting to go in the turbo. You could have someone drive behind you to look for any smoke from the exhaust.

 

Maybe try speak to Yousaf Al Wattar (ysfg35 on here) and together both of you can diagnose the issue?

Goodluck, and keep us posted, inshallah its nothing Major

 

i think you will need change turbos soon, cause they start drop oil. its normal situation.
and about noise maybe its from turbo, and turbo die soon. but maybe its from headers, headers leak also very offen situation

 

Do you see any smoke coming out while driving / stopped ?

 

Turbo seal leaking, its actually the lesser evil, if the oil is coming from the engine that would probably be tons of $.

If/When it goes its a perfect opportunity to get some nice 65-68mm ones

 

No smoke at all
