Crankcase Breather Valve soon going to heaven!

My friends Yip and Jed made a shocking discovery that stock Crankcase Breather Valve part # 034129101A has failed on their rides. True enough, upon taking out the engine cover, mine too soon going to heaven!

When this happens, boost pressure from the manifold will leak into the crankcase and if it got worst oil will blow out from the oil filler cap. Yup, this is what the CBV is designed to prevent in the first place but just like the VAG 2.0 TSI, it’s not doing it reliably at least on chipped ones. Luckily for me, there’s no significant oil loss by looking at the dipstick.

At the moment, we’re playing guessing game that the one fitted on Audi B5 A4 1.8T to be more reliable, part # 034129101B for RM80.00. Quite astronomically pricey for a “knob” made out of rubber and I still need to wait for 2 weeks, but AVS Auto folks will try to give speedier delivery. Oh well, if this also fails, I’m phoning Darian to courier TDI ones :)


Stock BCV on Polo GTI ... leaking

Hoping this is much stronger!
