I can be humorless and well as clueless...

Nah, I've just got a real Jack Webb style of delivery.
It appears I am also blind and cannot read. I just noticed you have always had the tag line about zip ties.
Apologies.

You have a great engine build going together.

No problem, and thanks!

Next step: The PCV lines.

This Genuine Volvo system for the 2004 S60R is available from either FCPEuro or IPD, and it costs about $370.

It consists of two lines: The red line is for coolant and the blue line is for air.

I am NOT paying almost four hundred bucks for a couple of pipes. Whoever set those prices must've been smoking the good stuff - you know, the stuff that makes you hallucinate Fat Elvis driving a freight train made of pineapples.

So I just need a couple of lines, one of which can handle moderately-hot liquid. Okay, I can do that. Lowe's plumbing section to the rescue.

This line has to run from this nipple on the thermostat housing to this banjo fitting (not shown) on the back of the head.

I'll flare the ends of the resulting line, blast it with some high-temp clearcoat and join it to the fittings with rad hose. Simple. Throw a couple of insulated clamps on it to hold it in place and done. I'm not sure about the air line yet. I'll probably see what McMaster-Carr has in the way of plastic line. So for probably $70-$90 bucks, I've solved the problem.

$400. They don't think much of us, do they?

Addendum.

I know that the lines I'm replacing are a $200 part, instead of $400 for the whole kit. That's still outrageous.

Besides, I'd rather make the new lines myself.

Moving on to the coolant bypass line.

I measured the tubing, cut it to length and taped it. Obviously this is just the mockup. I still have to solder the lines together, flare the ends and get some insulated brackets to hold the line securely.

You just introduced a big surface area of Cu into your Aluminum cooling system. I wonder where the more chemically active Aluminum will erode??

Nice work! That hose is outrageously priced, and that's one reason we don't typically replace those with the PCV job on these '99+ engines. They usually don't fail, being aluminum hoses. That certainly doesn't mean they can't be clogged though.

In the thin, expensive parts of the radiator?

I really don’t know but dissimilar metals in hot conductive Electrolyte can create a battery of potential problems

Maybe I can coat the inside of the line with something.

This is the same reason you do not want to use a galvanized pipe in a copper or brass piping system. It may take years, but a leak will form.
