Rennix 2.5 rear plastic line (PCV?) has hole in it

[ocean]

I was looking at the TBI in my 89 manche when I noticed that the PCV has a hole in it.

 

My question is what would this lack of PCV do to my motor?

 

Thanks in advance for expanding my manche knowledge!

Okay, so I know the line itself is hollow but the hole that was worn though just seems odd, there's nothing around it that should affect it like that.

Might help if we had a pic of what you're talking about. :thumbsup:

I'll get a pic up, I was curious about how the PCV affected engine function.

 

Thanks for the reply!

The PCV system ventilates the crankcase. The rear (small) line is the suction line. The larger line in the front allows (supposedly) filtered air to be drawn into the crankcase. The PCV valve (2.5L engine only, the 4.0L doesn't have one) is a one-way check valve.

 

Crankcase air is pulled out through the small line by vacuum in the intake manifold. The hydrocarbons in the mix are then burned in the combustion process. If you have a hole in the small tube, you have a vacuum leak. That makes your mixture run lean, which can fool the computer into injecting more fuel than is needed.

Repairing a broken vacuum line is easy. Just cut the plastic line where the hole is and slip both ends into a properly sized piece of vacuum hose.
