What does a PCV reroute do on a Duramax?

Registered. The PCV reroute will still let your crankcase pressure vent excess pressure & oil mist. It will just be venting it somewhere else (atmosphere or catch can, that’s up to you) rather than into your intake/intercooler/turbo….

What is wrong with LB7?

The LB7 Duramax is more prone to head gasket failures than future generations of the Duramax engine. Despite this, head gasket failure usually doesn’t occur until over 100,000 miles, so it’s not nearly as common as it is in 6.0L Powerstroke engines. LB7 Duramax head gasket problems can occur for a couple of reasons.

What is a PCV reroute LBZ?

“What is PCV reroute” you ask? PCV reroute is a must do mod it cost roughly $100.00 bucks but will save you thousands in the long run. It is where you reroute the positive crankcase gases to the atomsphere instead of have them go right back into the engine via the turbo inlet.

Is the LB7 reliable?

Overall, the LB7 is a very reliable and efficient engine with exception to the injectors faults, but beyond that, the truck will only need basic maintenance and last for several hundred thousand miles.

Why do a PCV reroute?

The stock PCV system allows LOT of oil to get sucked into the intake, which ends up spewing smoke out the exhaust. The PCV Reroute will allow you to retain the function of the PCV system while helping to reduce the amount of oil consumption caused by high lateral G-forces in cornering.

What is a PCV valve do?

Essentially, a PCV valve controls emissions — it takes the gases produced by the crankcase and routes them back into your engine’s combustion chambers to be safely burned without harming your vehicle or the environment. This prevents the crankcase from developing engine-damaging oil sludge.

How much horsepower can a LB7 handle?

Max “reliable” HP I would go is 400rwhp. Anything from stock is a risk of breaking somthing. Ive seen rods bend before headgaskets blow. Generally, rods are good to 500-550, IMO, pretty much anything over 500 is taking a risk of bending.

What is the purpose of a PCV reroute?

Can you bulletproof a LB7 Duramax?

Unfortunately there is no way to bulletproof these injectors. Between the voltage going to them, and the fuel quality being so inconsistent, air, water, and debris the gets through the system, and how the truck is used all makes a huge difference in how long the injectors last… Plus what cores you get from reman set.

What happens if PCV valve is disconnected?

PCV system routes oil vapours back to the intake to prevent blowing them to the atmosphere. If you disconnect it you’ll have a cleaner air available to the combustion process, and so better performance.
