SLP SHORTY HEADER problem

Help! My SLP headers keep on burning up heater hose lines... I've tried coating the hoses with that heat temp stuff, zip tying them out of the way.... nothing seems to work...... 20 min's of driving and coolant everywhere.... HELP!

Also, I can't seem to get rid of this annoying exhast leak... it's almost like a ticking noise... I've yanked the headers a few times and replaced the gaskets etc... this last time, I put some RTV sealant on the gaskets also which helped some, but it still ticks... I don't dare tighten the bolts anymore than they are because it appears that I'm starting to strip the threads on the heads.

Check your EGR pipe that was were my headers leaked. Have you tried to rig up some kind of metal sheild to block the heat. I know there is not much room but just an idea. Wrap the lines and then put up another sheet of metal or wrap them a couple of times

I have an EGR block off plate... I dont' think it's leaking there... there is absolutely no room to make up a heat shield.....

what year is your car?

I just went to look at mine, and with single cat SLP shorties my heater hose is about 2-3 inches away from the header, and it has the stock fire sleeving on it so its not anywhere close to burning up...iis your significantly closer than that? Mine are uncoated too...

mine is a '97 and it's right up against it... this might have been a question I should have asked ealier.... am I able to swap the hoses around? One of the hoses is metal, the other is rubber... if I put the metal one closer to the header, I think it will give more clearance.

You have a 97 and I assume you have the dual cat headers for 97 shown here You say you coated the hoses with heat temp stuff? I think you really want to use some of the heat wrap material they show in the pic to wrap them with, I don't think spraying anything on rubber hoses is going to help.

High temp stuff = 2000 degree Heat wrap

That's why you're suposed to put the heat shield in before the headers.

I run the same headers with no heat shield and have not had any problems.

OK, just checking when you said "coating" I thought you meant some sort of spray or something. I don't know how 2000 deg wrap wouldn't work though.

Do any of you know if I can reverse the hoses on the heater core if it would still work right?

Get rid of the short rubber hose. Replace with metal hose with fire sleeve. Tie back with zip ties.JMHO
