Turbo, Rings, Valve Stem Seals, Blocked Breathers

 

had new rings and Valve Stem Seals, i was told the turbo was rebuilt by tt but has a lot off in and out play?

 

in and out play

 

so i need another turbo

 

in and out isn't good at all, means thrust bearing damage.
yes replace or repair.

 

theres ur answer.
turbo.

 

dam it

 

is it a t2 turbo???

 

If its just a smoking turbo and there is no damage where the compressor wheel has caught the housing I would suggest a rebuild kit.

I have just rebuilt mine using one at £57 from ebay from a guy called mgturbobits which includes a rebuild guide.

As long as you follow the instructions to the word regarding the marking of the shafts and wheels to maintain the balance on the shaft you will not believe how easy it is!

Mine is now totally smoke free and boosts like a bastard. My thinking was its got to be worth a go for £57 over £400 plus for a new one, even if it proved to be just a lesson in how a turbo works!
