compression test 200 200 200 200, if i go over 6k and when i start the engine cold he smoke for 30sec?? what do you think ???thank!

 

the blue smoke at cold start is coming either from ur valve guides or valve stem seals and as for the smoke coming out at 6k is going through your rings for the compression test u can still have high comp. due to carbon build up on your pistons u should try a leak down test

 

or it could be coming from ur turbo

 

how may miles are on your motor?? you could be getting blowby at high RPMs due to boosting.

 

8k since piston ,rod ,sleeve.....
