My car seems to judder a lot when accelerating and slowing down and after some reasearch I discovered that the most common problem was the breather pipes being clogged. i checked the pipes this weekend and surprise surprise full of yellow oily goo. I follwed the pipes to the air intake and noticed that the butterfly also had a nice coating of goo as well so..
Heres the plan.
I have ordered two new pipes (the large pre butterfly and small post butterfly) and will replace them except I am going to connect the lager one to a pipercross filter rather than the air intake which I am going to seal. i am then going to run carb cleaner through the butterfly and give it a good clean.
Will this work okay..... I have been reading about the "breather Mod" but I dont think I will have to get the drill out as it is only a 1.2!!
Will I need a cathcment tank or will the filter be fine without one (again it is nly a small engine)
should I be doing anything else to the engine whilst I am doing this at the weekend
The filter will work fine, although its better if you can run it to a catch tank as this will help prevent the filter and pipe clogging up.
If you do use a catch tank, dont forget to have either a filter attached to that, or a few holes at the top to allow breathing.
Many people use sprite bottles lmao which work fine.
Yep, seal off the pre TB hole on the air trunking, and run carb cleaner over the butterfly.
Be aware you might have trouble starting the engine initially until the TB dries a bit.
The small pipe you can seal off both ends, but being after the TB, its probably easier to just leave it on.
Collected the new pipes from Vaux last night chopped, cut and shut, blocked and filtered the big pipe and replaced the small pipe.
All I can say is wow....even on the small 1.2, wasn;t expecting any power gains but it certaintly drives smother up and down the gears. No hesitation.....I can now slow down to 15mph in 5th gear without judder and then smoothly acceleatre up to 80.......I love this mod.
On my old Corsa 1.2 16v Corsa, I had the same problems with the breather hoses getting gunked up. Didn't bother replacing the hoses, just took them off, ran hot water inside them until all the crap was gone, left the hoses to dry then fitted them back on. After that all was well!
