The DPI heater return kit definitely isn't necessary if your metal pipe is still in good shape. Mine wasn't, so I was glad to get rid of it, and replace it with hose which I can get locally if needed should it ever start to leak. The only real trick the DPI kit does is to convert from 3/4" to 5/8" heater hose, which the original OEM hose did via being different sizes at both ends (hard to find locally as well). This makes the heater easier to repair in the future, same day, without waiting for parts.

WD40 isn't that great for penetrating oil. I like mixing 50/50 acetone and ATF, or Aerokroil which is in a spray can.

You can put an extremely thin layer of anti-seize on spart plug threads and sensor threads but do not get it on the insulator or sensor elements. A tiny bit of anti-seize is all you should need.

Thanks! Much appreciated!

I think I'm beginning to understand the DPI solution here. Because the original setup also has rubber hose => steel tube => rubber hose, the DPI solution is just an easier way to get the same job done and would likely only require new hoses if it started leaking, whereas the stock setup would require either new rubber hoses OR steel tube. Makes perfect sense. Is the DPI rubber plain rubber or some long life variant or sillicone? Do you happen to know that?

The DPI hoses are silicone. DPI also sells a stainless hose clamp set that will do the entire car for a pretty reasonable price, and they are very good hose clamps, too. If you plan to eventually do every hose on the car, and you should if they are more than 15 years old, then the kit is a good thing to get.

When converting to silicone hoses be sure to use only clamps that are designed for use with silicone hoses. See this link for reasons why:

The DPI silicone hose kit includes such hose clamps which they also sell individually. Other D vendors offering silicone hoses also do this.

Since we're on the topic, correct clamps should be used on fuel lines too.

That sounds like something I’d order as well. Been looking for a kit of SS bolts/nuts/washers/spring washers too, for the entire engine bay. Quality hose clamps sound like a great idea.

Whoopsie daisy - I have to look into the entire propper hose clamps thing - I thought there was basically one kind.

See this is why I’m asking these basic questions, I have a sneaking suspicion that there is more to the basica than I understand. Suspicion confirmed.

Thanks! Any reason NOT to use sillicone compatible hose clamps everywhere? (Higher cost?)

I would recommend constant tension clamps. I have used them on all my projects over the years and have never had one let go/get loose. I love them. This AMS article references forced induction the same principle applies.

Thanks! I'll have a look, might as well get the best clamps now that I took the time tear the engine apart, I might as well put some quality in to it.
