Motion Raceworks LS Stainless Coolant Crossover Steel Steam Vent Kit
Our Stainless Steel Steam Vent System connects the 4 corners of your LS engine to remove trapped steam and get it where it needs to go. Steam / Built Up Pressure creates elevated temperatures. The LS engine has 4 corners for a reason and we suggest connecting them on ALL modified engines using whatever means are possible. When steam gets trapped pressures rise, when pressures rise it creates an unsafe tune condition which can lead to pre-detonation, head gasket failures, lean cylinders causing piston failure etc.
This system has proven itself time and time again in the real world with our customers. Adding this and our other style of steam vents have taken problematic combos where #8 and 7 cylinders were having gasket or lean issues and cures them.
It not only works well but looks amazing as well. This setup combines CNC aluminum manifold and corner ports with 304 stainless steel line. Each kit is hand built. Aluminum blocks are offered in black anodized finish.
Our Stainless steel system is hand built and 100% made in the USA. We take pride in fitment and quality of this kit. Gaskets come at no extra charge.
This system bolts to ALL series LS engines. This system has been tested with the following intakes and is compatible. Holley Hi Ram, Holley Sniper, Edelbrock Pro-Flo XT, Edelbrock Super Victor, Frankenstein intakes, Edelbrock Victor Junior, & Stock Style Plastic Gen 3 Truck Intakes. Will fit nearly any of today's long runner style intakes.
*Note this kit will clear factory knock sensors on Gen 3 engines.
*Note LS3 L92 and other heads have the rear ports blocked off. This block off is a simple aluminum plug. You can knock this plug out from the bottom out (if heads are off) with a punch. It can also be carefully drilled out as our corner blocks seal off the top flat surface. DO NOT enlarge the hole size overall. Care must be taken to not let aluminum chips fall into the head passage so we suggest multiple careful drills with vacuuming in between and possibly greasing the drill bit.
