Description
Test your BMW N55 motor for leaks the correct way and keep the motor running healthy and boost with confidence!
Pressurizing the system will allow you to run peak boost your motor was tuned for and ensure you are putting all the power down without any leaks. A boost leak will cause the compressor wheels to over-spin to compensate for the lost pressure. Eventually, this puts a lot of strain on the turbos and they start to develop shaft play from running hot and poor oiling. It's an inevitable test that every turbo motor owner should do to keep the motor in good health and avoid costly repairs, especially if tuned, street racing or any track racing. Too many times we've seen customer cars come in thinking there aren't any boost leaks or "it's been smoke tested" only to find some boost leaks. This throws off the tune, causes air fuel ratios to always be "chasing" for the loss in expected air, messes with ignition timing from increased air temps, and reduces fuel economy.
This boost leak tester will pressurize the whole charge pipe path and detect any leaks from the turbo to the motor. This includes faulty diverter/bov's, clamped connections in the charge pipe, intercooler, and all connections at the intake manifold. Basically, everything the turbo normally pressurizes
The boost leak tester will fit over the stock turbo inlet pipe. This is the block that bolts to the turbo compressor housing. With that said remove the oil cap! to keep your crankcase pressure to 0 when filling the system.
Some common leak points are:
- the o-ring connections at the outlet to intercooler, intercooler to charge pipe, especially with aftermarket upgraded intercoolers and charge pipes!
- PCV valve that is built into the valve cover
- torn diverter / blow off valve seal
- isolation of boost leak vs waste gate vacuum line leak
