Dorman 615-183 intake

[greatmizzou]

I feel a little sheepish over this but the dorman replacement intake manifold for GMT 800 engines has a unique manifold gasket set.

 

I didn’t realize this until it came in.   

 

Didnt see much much about this but generally it appears to be a more efficient design that is based off the FASTlxr intakes.  Everything else appears to be rather stock.

 

anyone have a negative opinion of these?  I find Dorman to be pretty OE and not anything flashy but not terrible either.

 

i have a phot of some sloppy factory gluing. I was told this shouldn’t effect leakage.

I have a Dorman LS1 intake on my LS1 Camaro and I love it. It installed like factory and no leaks. I did have to do some clean up of the runners but it was worth it.

 

From what I understand Dorman bought the rights for the lower portion of intakes from FAST and they Sonic weld their own upper design to them.

OP, I know this is old, but did you ever bolt this on?

I am thinking of replacing my truck intake with a Dorman 615-183 and the 07-13 intakes look like hammered dog Sh*

 

Your input is appreciated.

Just a quick question. Why are you wanting to replace the intake?

Doing a cam swap and heads. That intake has good numbers equivalent to the current intake and looks way nicer. It's also a lot cheaper than the LSx intakes.

 

I'll have to program the different throttle body as well, so I figured I would see if the OP had any luck

Putting it on today finally lol.    I’ll take pics

Seemed to go on just fine!  Will update the status once I tow my trailer around for a bit.  I threw p0101 again right after the repair when I hammered it down.   I realized though I left the Pcv valve disconnected ;)

 

code self cleared very quickly

 

my knock sensors were bone dry and looked great

My sponges were in good shape and still felt rigid.  I think it helps I’ve never washed the engine ever, and I’ve owned this since it was brand new. I was expecting water issues but honestly there were none.

 

Lots of squirrel nuts and bugs.  The daddy long legs was dead and crispy.  ;)    The piston chamber or whatever you call it was really gunky.  But seems OK.  

 

Honestly the job was way easier then I thought it would be.   I spent more time trying to figure out how to remove the fuel injector lock caps and at the very end I couldn’t find the egr sensor and ended up It got tucked under the manifold.  Glad I didn’t torque it down without it lol.   

 

Truck just feels cleaner running now when accelerating.

Couple notes on the differences of intakes

-no modification is needed from wiring harnesses

-map sensor goes on back of dorman intake and its on top of oem intake

-the evap solenoid?  Connected near top left throttle body is sort of in the way of the hose connection but it works and doesnt need modification

-the dorman intake has this white plug next to the intake I have no clue what that is for,   Maybe an egr valve?  

-you cant re use same bolts you have to use the self threading screws in the kit

-the 10mm intake bolts slip real easy so make sure you have a good socket
