I dont think Ever - drain plug was removed on my car it sits tight, should i use wd40 maybe or pb blaster? It is tight!! as a rock!

Last time I changed oil didnt bother removing turbocharger drain plugs so i thought i ask.

 

seems like nobody ever changes/removes the plugs, I managed to get one of mine out with some tricks, the other seized bad-drill out carefully ...replace both with new plugs
my neighbours new-to-him TT also has seized plugs, will be drilling his out too.

 

i'd rather change the oil more often than go thru all that lol. last time i ever drained the turbos my car made a cavitating noise which i hated.

 

lol, screw the turbo plugs, im not gonna even bother.

 

^ a wise man lol

 

I noticed one of my turbo drain plugs was cross threaded when I installed K16 billets.
Somehow I managed to get the bolt back on and it doesn't leak.
That bolt will never come out again unless I have to remove the turbo.

 

one trick you can try if you haven't already is, with a small and sharp chisel hit the head of plug(on the outside edge) in the counter-clockwise direction, using a hammer as force, if it's going to move at all it will with this technique...but its probably frozen ready to be drilled lol
attached a pic of method (made using my wicked 'paint' skills )

 

Get car as hot as possible - try it then b careful.

 

If you need to get them off, get a small propane bottle and heat up the area around the plug. Does the trick every time.

 

^_ I could do that, but do we need to really drain the oil from turbochargers?

 

not necessary, just something us OCD guys do
be careful with heat application, aluminum parts are sensitive...especially for strength-critical parts like suspension

 

I would leave them alone. The amount of oil that you can drain is minimal and the damage you can create is not worth the effort.

If you get it managed to get the plugs out, put them back in with ceramic paste applied to the threads to prevent seizing.

 

^ that's the best advice re actually being concerned about the oil, and if you are going to go thru all the hassle? then i would also put anti-sieze paste on them. the reason they're on so tight is they have never been removed and porsche oil services at dealerships won't get them drained ever either.

so what does that tell us....

 

i think it a good thing to flush oil in the turbo tank! just to be sure the oil check valve is not clogged as a preventive measure ! i had that suprise before that almost cost me a turbo....

 

tells me they are lazy. theres a simple reason to have these plugs accessed that nobody thinks about. if you decide down the road to change turbos or repair a damaged turbo the only way to get to the bolt that holds the turbo oil tank to the turbo is thru the drain hole!!! yes theres a bolt inside the tank, so do your due diligence remove the plug drain the oil when you do your oil changes and you will thank yourself down the road
