In 2001 and 2002 with the addition of the ls6 (zo6 c5) intake to the ls1 motor, engineer came up against clearance issues with the steam/crossover lines, and blocked off 2 of them. At normal to moderate power levels, this has little known effect. However once some real power is made, it only speeds up the process and leads to higher temps, which most certainly contribute to ringland failures, melted pistons, among other misfortunes. I am writing this that way its easier to find in the event someone does not know it and finds this thread. Its becoming a more prevalent topic these days. The solution is to either buy some stock lines and plumb them in, or contact Kurt Urban and buy one of his pristine kits. Well worth the money IMO. Anything that keeps those temps down, is good insurance for a long happy life for your motor.

Definitely something you need to keep, or find a way to improve upon the factory system like the aftermarket one mentioned or something of your own.

question, is he refering to completly deleting the steam tubes or converting to an LS6 style where only the front steam tube is used and blockoffs are used in the back?
now i have seen some steam blocks that have an fitting built into them. that would look pretty trick without going too "race car" looking so as long as you get black or silver instead of the traditional blue and red an fittings.

I'm thinking of welding on an AN fitting on mine so I can use a good hose. The hot coolant is making the push-loc hose I have on there now get kinda hard & i'm worried about a hose failure.

if i knew any of our sponsors sold them id put a link up but i dont know. I know though that you can find them for a decent price with AN fittings already on them. I was thinking of running an fittings on all of mine and tieing them all together like the stock LS1 has and then running it back to the coolant tube.
ITs either that or reuse the stock ls1 steam tube. if you have an LS6 intake, you'll have to grind some of the ribs off underniether to get it to fit right. some have done this with success.

I PM'd Tony Mamo about if the thought the bottom of the FAST could be notched to allow the stock LS1 or fabbed cross over to run underneath it, he told me he believed the #7 issue to be inherent to the stock intake design and has never done it before (the main argument against weather its worth tapping into the steam ports is that some people just say that the problems are because of the layout of the stock style intakes and the steam port isn't the real issue). He went on to say that if the tune is not on the ragged edge he feels you should be ok, so... that's both sides of the argument.

I am new to this site and to LS1's. The '67 Camaro I just bought has a '98 LS1 and the steam ports are capped. Even though the engine is bone stock, it sounds like I still need to add steam tubes. If I can find the stock tubes, will they work? Thanks.
