Thoughts on exh sleeves

with 3406E we had to pull sleeves out to change, C15 is relativelly not so old and they keep running, we use to change injectors only.... Yeah, it is CIS experience, but I sugest they run the same way in the USA and may be its life is longer becouse not so many cold starts in winter at below zero temperatures

 

I though someone said without them they spool slower. I just had all mine replaced due to a broken stud and had one missing. No idea where it went or if it was missing at the factory. So unless it broke into pieces and made it through both chargers without making a sound it's going to remain a mystery.

 

I never put them back in.Cut the rivets and use the outside gasket.

 

we had one come out and ruin a turbo. i wondered the same thing tho since thats a pricey ordeal.

 

Just as BP said...
had a sleeve go through turbo on a 2WS. New turbo...

 

Possibly, but they didnt use them on the older engines, so I dont see why there would be that much difference.

 

I had one go through the turbo 4-5 years ago and ended worrying about it happening in another hole.....removed the sleeves. No problems since.

 

please educate me, lol what are the exhaust sleeves? are they a after thought , a sleeve to decrease the runner size in the exhaust?
