I Don't Think This Is The Correct Way To Install A Catch Can?

As long as there is a breather pipe going back to the intake pipe there's no dramas, the tool that put a can in my car before I got it had it all wrong and it pumped heaps of oil out the exhaust. Would work better inline with the breather pipe though (i.e. inlet side of the rocker cover > exhaust side > catchcan > intake pipe) :no:

are u trying to catch cans?

:P

:no:

what is that doo-dad core thingy behind the drivers light infront of the radiator? is that a series 2 thingy?

I don't know, looks like some sort of cooler, I'm guessing it could be auto transmission oil cooler?

yep, its an auto tranny cooler.

as long as you've got a breather on the catch can as well as the other pipe thats on the exhaust side blocked off (the one with 2 coming out of it) you should have no problems.

The passenger rocker cover is still feeding oil vapours back into the inlet side of the turbo.

In my installation, the catch can basically replaces the hose from the passenger side rocker to the turbo inlet (that 'U'-shaped hose coming straight up off the passenger side rocker).

If there is no breather OR it doesnt breath back to the intake pipe, crankcase pressure will throw oil out of the dipstick. When I got my car, there was a hose from the intake manifold > inlet rocker cover blocked off. There was then 2 hoses going from each rocker cover to the catchcan with no breather.

The engine was throwing HEAPS of oil out of the exhaust, I reconnected the hose from intake manifold to inlet rocker cover and it stopped throwing it out the exhaust, instead it started trying to throw it out the dipstick. It was abotu then that I realised it wasn't breathing.. so yes there are wrong ways to hook them up :woot:

      Did tie rods. Steering now not "springing" back.

      Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Sounds good.  I don't 100% understand what your getting at here. When you say, "I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down" do you mean this - there is a panel with factory paint, without any prep work, they paint the entire panel with primer, then colour then clear?  If that's what you mean, sure it will "stick" for a year, 2 years, maybe 3 years? Who knows. But at some stage it will flake off and when it does it's going to come off in huge chunks and look horrific.  Of course read your technical data sheet for your paint, but generally speaking, you can apply primer to a scuffed/prepped clear coat. Generally speaking, I wouldn't do this. I would scuff/prep the clear and then lay colour then clear. Adding the primer to these steps just adds cost and time. It will stick to the clear coat provided it has been appropriately scuffed/prepped first.  When you say, "but the new paint is landing on the old clearcoat" I am imagining someone not masking up the car and just letting overspray go wherever it wants. Surely this isn't what you mean?  So I'll assume the following scenario - there is a small scratch. The person manages to somehow fill the scratch and now has a perfectly flat surface. They then spray colour and clear over this small masked off section of the car. Is this what you mean? If this is the case, yes the new paint will eventually flake off in X number of years time.  The easy solution is to scuff/prep all of the paint that hasn't been masked off in the repair area then lay the paint.  So you want to prep the surface, lay primer, then lay filler, then lay primer, then colour, then clear?  Life seems so much simpler if you prep, fill, primer, colour then clear.  There are very few reasons to go to bare metal. Chasing rust is a good example of why you'd go to bare metal.  A simple dent, there is no way in hell I'm going to bare metal for that repair. I've got enough on my plate without creating extra work for myself lol.
