Head Gasket Replacement

So some of you guys seen my earlier post about milky oil. I have a blown head gasket for sure. :

Can you guys please tell me where I can find a good parts for the new gasket and head bolts. The engine is only 20,000 miles old since it got rebuilt in 2002. I dont know if the bolts are reused or new. I want to get new ones anyway.

I have Borla headers, do I need to get new gasket for it too since I have to take that off too.

Do anybody want to come over and help me replace the gasket? I have a case of beer!

Use a felpro gasket set, that should come with everything you need.
I have no problem reusing head bolts and have done for 30 years as long as they are not TTY you are good. If you must get new head bolts use ARP. Make sure the head is not cracked or warped before you bolt it back on, a machine shop shouldn't charge much to pressure check the head.

I can tell you that Fel-Pro has never done me wrong in the gasket department. 25.00 at Napa

Getting new head bolt is a good idea. I can't find them at Napa online but you might be able to get them in-store

Yes you DO need a new intake/exhaust gasket. 21.50 at Napa

This the seqence(sea-kwence) that the bolt are supposed to be tightened in the intake/exhaust. The numers I wrote on there are the torque specs. Iirc they are in ft/lbs EDIT: These nubers are for a 4.0 the order is probly similar not sure about the torque

Not to highjack, but should the head bolts be re-torqued after a run in period? I just re-did the head on grandaughter's 2.5 Wrangler, and I got conflicting advice.

I guess that would depend on the advice from the gasket maker.
The Felpro perma torque gaskets do not get retorqued.

You may want to spend the extra few bucks $30 or so and have the head resurfaced. Ask me how I know...

Make it run hot and often water in oil. I have had them where they ran rough and pull a spark plug and water pours out..not a good sign......

Hmm, the jeep do not run hot at all. The temp is perfect on the spot. When it is warmed up, it want to stall so badly and it stalls at any rpm. I still think I got blown head gasket but I am not too sure anymore

Stalling is usually not a blown headgasket. Do a compression test and check to see if the oil is milky in color. A stall can be caused from a bunch of much simpler things.

Check the plugs, take a pic and post after you pull one. You can tell alot by an engine by the color of the plugs. .
