Head gasket replacement 1998 K2500

[TommyJ1980]

1998 K2500 5.7L 250,000miles. I know the folks who will see this have been commenting on my other thread where I was trying to gather info on a new motor vs doing this. Well, long story short, the evening of the same day I was at O'reillys looking at crate motors, I got a large tax bill, sooo......we're opting for plan B to replace the head gasket, and that'll give me time to do some more reading on the subject anyways before plunking down a bunch of money. Last thing I was able to find TDC compression thanks to your advice, and the project will stay like this over the next few days while I drive around a Volvo with a chicken decal on the back of it. Here's the supplies I gathered, any thoughts on the selection of gasket sealant? This came recommended by the store manager but I can easily swap it back out for a different kind if its wrong. Thanks all, have a good week.

You need a head gasket set, not just 2 head gaskets. Probably going to need a new QD fitting for the heater hose on the intake manifold as well.

Also a thread chaser to clean out the block threads…

And a torque angle gauge or digital torque wrench for the head bolts. I’d buy new head bolts though the manual implies that the existing ones can be reused.

So I bought an intake and valve gasket set first, then these ones with new bolts. Am I missing more?

Just exhaust manifold gaskets. Now is also a good time to do valve stem seals. And maybe new exhaust manifold donuts if the old ones come out hammered.

Appreciate it!

Not sure what’s going on here with these wires, looks like a ground? I’m seeing all this old tape and wondering if any of this should be replaced or if they were just trying to put a primitive heat shield of some kind in place or something

That is factory heat shielding tape.

Dumb question of the day here- broke this right in half trying to pop something off the bracket next to it- what is this piece here that goes down into the valve cover, so I can go grab a replacement? Thanks
