Need some advice. I believe I have a loose sleeve in my exhaust port. On a 90 tubo motor. Short of disassembling the engine. Anyone have any luck fixing it from the exhaust manifold side. Its a nice rattle right above idle, driving me nuts. Thanks for the input.

 

Sure its not your wastegate???? I find it hard to believe its a loose exhaust sleeve. Theres no reason you would have to disassemble the motor to work on a sleve anyways, the only way to is exernally. They are held in by pressure pins that it takes a mig welder to remove. One could mabey have fallen out, but those are in there so tight I dont see it happening.
Pulling the turbo/manifold should give a good idea whats going on.

My car did that and it was just the wastegate.

 

Yah, I'm having problems REMOVING mine, so I really find it hard to blieve it just fell out for no reason. Never heard of that happening before.

 

I never said it fell out. Just that i think it is loose in the port. Also it was the waste gate. What part, the actuator, rod, flapper, cover plate,.
thanks
