Oil Catch Can, Eliminate that knock!

I inspected the staus of the hoses and replaced the splicers with plastic barbed ones , I believe the melting point of the splicers is 160 °C, question is how hot will it get in there.

The hoses provided with the occ kit are choked, without wire mesh and too thin, my advise is to discard them and not waste your time with it.

The new hoses are advertised as heat and oil resistant up to 240 °c, they are thicker and have a wire mesh which helps not to choke, they are 5 euro per meter on aliexpress.

I ordered stainless steel splicers, they were advertised as 8 mm, but they actually were 7.3 mm, so too small, I returned them and ordered new 9mm brass ones.

I also had some 9mm plastic splicers around so I'm using them until the brass ones arrive.

At the same time I replaced the intake gasked.
It was about 4 euro on aliexpress.

 

Wondering if geographical location changes severity or likelihood of issues

 

Not really. It’s the weak pressure for the piston rings and lack of large enough ports on the piston
for the oil to distribute out.
Also, doing 10,000 miles oil changes makes it worse. So some say.
Also, driving in the city with stop/go driving, the engine is on an off a lot.
Highway drivers have less of an issue because the engine is running constantly.

 

Which issue in particular?

For the steady delivery of oil to the intake manifold via PCV, the location of the PCV input might be a factor. Gen 2 took it only from the valve cover if I’m not mistaken. On Gen 3 it mostly from the block, feeds into intake manifold, just below throttle body. There’s also a hose from valve cover to engine air intake (downstream of filter, upstream of throttle body); it doesn’t seem to do much, and no evidence of oil.

I don’t think geographical location matters, for the PCV oil dump anyway.
