turbo blow up?

Looking forward for SmokinCat opinion on this...........

 

I'm pretty sure it is just a progression of part numbers for them, I think they make small tweaks to either the design of the bearing housing or maybe even wheels, but nothing major. I have seen some info on newer cat engines that have the listing of the S430.

In my mind they need to do a rework of the turbine to allow some better breathing on the exhaust side, that will always be the brick wall with the S4XX series turbos on large displacement engines.

 

it is virtually impossible to get debri in the oil through the turbo when the wheels fly apart like yours did. the only way I can think of is if the shaft snaps between the bearings. your cac if you ever cut one apart will only let very minuet pcs through that will be injested by the engine with no damage. the big pcs as you found out will be on the hot side of cac. but at least you know for a fact now about your oil pan. I had a cat turbo break just like yours did 2 months ago at low idle. split into and broke some blades off. was bobtailing drove it 10 miles home like that, talk about a weak running engine!

 

Dang, sorry to hear about your turbo failure! Really good you were close to home. Is the turbo that blew a Borg Warner?

 

The reason I ask is when I was talking with Leon about my Detroit 'changes', he's seen many BW turbos that were not genuine and are actually Chinese made. Supposedly the impeller assembly was of the powdered metal variety, not even forged steel. Unless it is a factory direct dealer, they could have the Chinese made and not know it. Probably not your case, but something to think about anyway.

You're right on about the Detroit BW. $700 out the door no core charge.

 

one day my neighbor took his oil pan off to put a new pan gasket on it, to help with oil leak, he found a tooth of a gear in pan. so I just leave mine on, afraid to look.
