I am doing round 2 of the CNT EL header myself. I purchased a 2004 Forester XT to succeed my WRX wagon after blowing up 3rd gear, and a few months ago I diagnosed the Forester with a blown ring land on cylinder 4.

I bought another CNT header to install with the new motor, can't wait! I am actually doing a full oil cooler delete this time.

I'll document the install on my Forester's new motor here as well.

This time around, I was trying to save some cash here and there, but also build a very reliable engine, as this is my daily driver. As such, I wanted to go to EL headers due to the very flawed UEL design being credited to so many cyl 4 ringland failures, such as my own.

I bought an STi oil pan and dipstick to replace the square one that comes with the 02-05 wrx 2.0L engine, and the 04-05 FXT, probably the early side feed LGT and OBXT, Baja turbo etc.

Part number:
Oil pan
11109AA151
Dipstick
11140AA150

Also did a Moroso pickup to get rid of the cracking OEM pickup problem.

I did a full oil cooler delete, just because this is not a high power car, and a lot of reading showed that the oil cooler is most effective at warming up the oil when the engine is cold. Well I live in Florida.

The "right" way to do this is to also get rid of the coolant lines that pass through the oil cooler. I plugged the block port where the coolant fitting goes, and installed a water pump from a newer model Forester XT/WRX that doesn't come with the oil cooler from the factory (another reason I felt comfortable deleting mine).

Part numbers:
Coolant plug
11021AA121
Oil filter union
15018AA090
Gates water pump
42030

Problems:

Of course I had problems. I bought the header from CNT's "used/open box" section. They were $200 shipped, which was nice. They arrived looking like they had never been run.

I installed them with brand new OEM gaskets out of the master engine gasket kit. From here, I could basically tell they were going to leak.



The flanges looked warped, or almost like they had been ground down. Either way, the flange just didn't look square. The picture pretty clearly shows how the MLS gasket isn't quite sandwiched down. I was pretty certain they were going to leak, but I decided to run them to see what would happen.

Sure enough they leaked. I pulled them off and threw the stock header back on. I decided to take the CNT header to my local machine shop and have the flanges decked. $85 later, I reinstalled the headers.



Success. Kind of frustrating, but they don't leak anymore. I called CNT and got a very firm "No" when I asked if he would possibly help reimburse me some of the machine shop costs. In his defense, his used/open box items very clearly state they are ineligible for returns, warranty, etc. In my defense, these visually looked like they weren't gonna work out of the box.

Such is life, I still saved a few bucks and they work.

Another update- I sold the CNT ELH from my Forester after putting about 20k miles on them, zero issues. I'd say long term quality is up to par.
