Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model

- Iveco 334TM2 three-cylinder 3.4-liter engine installations using turbo 4037141
Product Overview
Blue oil smoke, a sharp turbo whine, low boost, oil in the compressor housing, or excessive shaft play can point to a failed turbo after intake leaks, exhaust restriction, crankcase pressure, and oil supply are checked. Installing a turbo without correcting the cause can ruin it quickly.
The turbo uses exhaust energy to compress intake air for the 334TM2 engine. It does not correct worn engine rings, injector faults, plugged air filters, a leaking charge-air path, or low oil pressure.
Confirm the loader is an LS185.B, identify the 334TM2 engine, then compare 4037141, turbine and compressor housings, flange pattern, oil feed and drain positions, wastegate layout, and product photos.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application that is not shown above.

Frequently Asked Questions
Q: Can a bad turbo cause blue smoke? A: Yes, but worn engine components, overfilled oil, restricted drain, and crankcase pressure can also push oil into the intake or exhaust.
Q: Will it fit an LS185 without the B suffix? A: Do not assume it will. Confirm the LS185.B model, 334TM2 engine, and 4037141 housing layout.
Q: Can I reuse a clogged oil feed line? A: A restricted or contaminated line can destroy the replacement; inspect or replace it according to service guidance.
Q: Is this an original-equipment part? A: No. This is a new aftermarket product. Brand names and part numbers are used only to identify compatible applications.
