Topic: what temp do exhaust manifolds and turbo's get to . (Read 8503 times)

i have a slightly warped flange that the turbo bolts to. so when i took our the turbo and looked at the
metal gasket i could see where exhaust trails were left from leaks.

i am thinking about just flowing some solder onto the gasket to thicken it in certain spots. solder melts
around 700-750 degrees. i would use a mill if i had one.

anybody know the temps of the exhaust manifold and turbo itself.

Sand paper and a block of wood............Get it done!

Sand paper and some surface that's dead flat, like a thick chunk of granite, glaass, etc. Get both surfaces flat (manifold and turbo) and then apply a thin coat of heavy grease and assembly with no gasket. Torque bolts to 10-15 ft*lbs and wire them together. Will never leak and bolts will never stretch or back out.

800 to 1200

GF's bro's Duramax sits at 900F cruising.

Diesels run cooler exhaust temps than gas motors, fyi.

solder is gonna melt on a turbo mani, throw a belt sander on it, just get it flat somehow.

toyolla86 · « **Reply #5 on:** October 12, 2009, 09:10:41 PM »

damnit i was trying to avoid any manual labor. looks like im stuck. any suggestions on type of sandpaper. metal type and grit.

marcj · « **Reply #6 on:** October 12, 2009, 10:02:06 PM »

i've used a POS black&decker belt sander from walmart, and then returned it ftw.

solder? are you fucking serious? solder melts around 200*C

toyolla86 · « **Reply #7 on:** October 12, 2009, 11:14:10 PM »

actually 400c and 700 f. give or take a bit. haha.

i was thinking exhausts dont get hotter than 700.

dont some people powder coat them. powder cannot withstand
much more than 450-500 f.

you mean ceramic coat?

toyolla86 · « **Reply #9 on:** October 13, 2009, 12:44:11 AM »

no i meant powder coat.

ceramic coating is ok for exhaust right.

turbob16hatch · « **Reply #10 on:** October 13, 2009, 01:07:58 AM »

yeah i have seen some atv exhaust stuff that was high temp powder coated. it looked liek shit and was falling off from the heat. didn't last long at all.

ceramic coating is what works, kinda....

I have seen it

Yep. Been doing the same for about 4-5 years since a local showed me the trick. I don't see any reason to use anything else, works better than OEM gaskets.

Yeah, but he's stale so it doesnt matter.

Passenger · « **Reply #21 on:** October 21, 2009, 08:30:43 PM »

There isn't any need for gaskets or sealants if the surfaces are actually flat, belt sanders are the cheap weapon of choice.

toyolla86 · « **Reply #22 on:** October 22, 2009, 12:47:00 AM »

i put high temp disc brake grease in there.
hope it doesnt burn off.
