It can still be a problem without sensors. A buddy of mine made an off-read excursion during a track day and even with the undertray in place, the hoses got bumped enough to break one loose spilling oil all over the track.

 

Thats why i used silicone, it oval'ed out enough to get through the hole. I believe accordfreak modified the HR pipe enough to fit through the hole. But with the large supply of silicone hoses Z1 has it was easier to weld a nipped to the Y-pipe and use silicone

As for the joining of hoses, i used SS hose joiners (i believe they are called) that hose is very odd size (same as stock going from hardpipe to rad), i cant remember off the top of my head.

 

on mine, i cut off the front end of the pipe and welded on a 1.25in straight pipe which is the almost the same diameter as the HR pipe. So the pipe goes through the hole almost perfectly. I say almost because some the rough casting around the hole needed to be sanded down. After sanding, it fit perfectly. A rubber hose from orielys or autozone was used from the pipe to the radiator. I then used a hose clamp from orchard supply along with some left over OEM brackets to bolt on to the timing cover to hold the middle pipe in place.

 

Mine ended up being a little complicated.

After calculating the oem pipe volume I think I ran (3) 3/4" hoses. Starting at the Y pipe up the V and exited thru the 1 x 3 hole. The 3 hoses feed into a new custom fill port / bleeder port at the front of the engine. In addition, I tapped and connected the "Pathfinder" port to one of the lines.

I assume this is all good since it is just like the HR...."system high point" bleeder and convenient fill port.

 

My idea was to re plumb the the stock oil heater/cooler by removing the plug and opening the port on the right side of the engine. Then run a short hose to the cooler and run a new hose into the rad. return...... This would clean it up a little.

Will probably scrap this idea and the oem cooler but was wondering....
Is is possible to tap into this port or would this screw up the coolant flow dynamics...???

 

Great pictures and write up on page 8 by JasonZ-YA as always

 

I plan on doing this mod over the winter. I found 2 different reputable companies making silicone "blanking caps". Any vendor deal with these companies want to step forward so I can order some of these???

Sard also seemed to have one but I couldn't find a link to it.

I noticed a few people mentioned that 06+ doesn't have the oil warmer/cooler.

I have a revup and it came factory with one.
I left it on with the non thermostatic adapter and will remove it with the mocal.

 

I believe they meant 07+ HR and VQ37s (pre 12') do not have one.

 

I had a (un-named) shop install an oil cooler. They didn't "Like" the stainless lines I purchased per Binder's thread a while ago. SO they made their own which they failed to secure. My assumption is there was enough movement caused by air flow that the line flexed for a year in a certain spot eventually breaking.

Oil literally spraying out the front of the car making it as far rear as the trunk lid.

Ironic thing is I still had the less expensive oil line I had purchased and it worked fine to replace the busted one.

A few zip ties and I wouldn't be worried about the potential damage done to my built engine.

 

What coating is done on the timing cover?

 

paint......

looks like good ole paint.......excess seal is painted too..

Negative, Its PC. And yes the idiot PC'ed the sealant, but it was a free job so i'm not complaining... The color is called something chrome, it was sent to the guy to be polished, he decided he couldn't pull it off so he said he would PC it a "chrome" color for free, in the sunlight it does look polished.

 

^ interesting, i didnt think it was cause i would have thought the heat involved with pc would have ruined some of the seal....regardless, it looks great...

Thanks, I guess you could say it did "ruin it". It made the sealant hard as a rock and leaked. So i ended up scraping all that off and resealing.

 

wow! excellent mod and write up guys i might have to do this. The engine looks so clean with the powder coat on the pipes as well

 

I never heard from any vendors on here so i went straight to a manufacturer. Is anyone else interested in this product to cap off unused radiator coolant lines when removing this?

Venair already makes this product in another size which is used for this exact purpose, and is going to make a small run of reinforced silicone 4 ply blanking plugs for me. If anyone is interested pm me. I'm not sure on price yet, but gauging interest to see how many of these I will have made.

 

Wouldn't just be easier and better looking if u just took your pipe to be welded?

 

not really... I would have to remove it from the vehicle which would not be easier. I dont think these will be noticeable and will be of high enough quality to not deteriorate. It performs the same function and since I do not have a tig welder this is something I can do myself.

 

u r right...ur way would be easier
