Intake Manifold Gasket (my own Do-It-Yourself experience)

[Suburban-97]

I am not sure whether the 2500 and the 1500 are similar when it comes to this fix, but if you look at the pics in my very first post on page #1 and they look similar to what you have, it shouldn't be much different. Both are Vortec engines, but as another poster (Torque_Nut) mentioned earlier, these engines have a different configuration. I don't know what's different, never looked under the hood of a 7.4L, but I just wanted to wish you luck with this repair. Maybe you return here and let us know what's so "different" about the 2500.

Have Fun!!!

Thanks. I'm being told it's basically a bigger version of the 350.
My concern is mounting brackets, like the AC with the "magic bolt".
Those little secrets can save time and aggravation.

The upside is, I can take my time on it an do a clean job and change out parts and improve stuff as I go.

My 98 Yukon is running now -- purrs like a proverbial "kitten" and I'm happy as a proverbial "pig in s*#@" -- for now, let's hope it keeps on. So far no leaks or codes.

Thanks to Suburban-97 for the helpful thread.

One thing that could be emphasized is to hand crank the engine to TDC before removing the distributor.

I didn't pay enough attention to mark the distributor and rotor position. So, I ended up having to time the distributor. And, that meant that I had to reposition the oil pump shaft. I couldn't feel the shaft with my very large long screw driver and "assumed" it was too big.

So, I carefully put a bit adabter and screw driver bit on a long 1/4" extension. I turned it some, but still couldn't seat the distributor. On my second try, the extension came back missing the adapter and bit.

I posted in the Yukon forum:

Everything seems fine now. But, I do have a small nut and a smaller nut left over.

For an old poop like me a must have tool was my over the fender creeper. Let me lay on a nice cushion while working on the truck. Best 200 bucks I've spent in a long time! http://www.amazon.com/REL-Stapleton-...opside+creeper

I think I may have to do this repair. Need to verify it's an intake manifold leak but pretty sure. I know this is an old thread but great info. Read as much as I could but wanted to ask is the Fel-Pro gasket is the best way to go and is there any difference for a 454. (97 3/4 ton sub)

Thanks for the response.
Got the felpro gasket from rock.
Watched videos, not much of quality out there.
So many praised the write-up here, was just hoping that someone who had accessed it and saved it was still around.
