The delete kit comes with 2 3/4" bypass caps. These are to cap off the 2 places where the 3/4" hose came to and from the EGR cooler. These are no good. Someone alerted me about 4 months ago that theirs were leaking. So I took a look at mine and they were not leaking but badly cracked. I bought new ones locally somehow thinking that the end result would be different. But now 4 months later the same thing. Mine are not leaking but are badly cracked and likely on the verge of letting go. All I can figure is that maybe the bypass caps are meant as a temporary bandaid to bypass a blow heater core and are not meant to be use permanently??? Anyone??? All I did was use a short peice of 3/4" hose, a 3/4" plug and 2 hose clamps (x2). Anyone have any better ideas? The top one is really easy to change. But the bottom one is a real PITA, this is my third and hopefully last time chaning it. I can't immagine trying to do this on the side of the road (without a garage full of tools). It is tucked in under the airbox. You need to take the airbox out and you can access it from above (but you and see it). You need to tighten the hose clamp from below with a min 24" long screw driver. Pic 3 shows it from the bottom, you can just see the 2 hose clamps on the RHS of the alum pipe that passes through the middle of the picture near the top. Pic 1 is the bypass cap as it looked today, before I took it off. Pic 2 is my "fix"? Pics 4 and 5 are the bypass caps stretched to show the cracks. YIKES.
Anyone installing this kit will want to do something better than the bypass caps. Had I know I would not have had to do this 3 times. I don't see why my fix will not work? But if I have any issues I will let you know!
Hope this helps someone.
