Maybe not a new one but i would pull it apart and check it. More than likely yes.

Well if I pull it open, it's definitely getting a new one.. This is frustrating.

Well, Its okay if It's challenging. Just not challenging enough to make you not even want to do the swap. haha.

Spending loads of money on tools isn't the best feeling either. haha.

NOTE: dont use purple power by the idler pulleys. they will dry the bearings out... Learning new things.

well aware of what all the GENIII motors are capable of and for his jeep a 4.8 is plenty if that is what he has

never had any issues with purple power on bearings

also if you are pulling the head off pull both and upgrade to MLS gaskets from a 02+ motor. those early graphite gaskets suck and should be changed in pairs

Well maybe my bearings sucked already and i just finished them off.

Will new MLS gaskets seal? ive got the 862 cast heads and they have the recess by the second cylinder.

Yes or I wouldn't of suggested it. Your motor isn't anything special versus other Yrs. Upgrading to mls and new gm head bolts isn't a problem.

My motor is a 2000 and I swapped to mls and used new gm bolts.

And no you don't need to have heads surfaced. The small variances will be made up by the mls.

P/N for the gasket? from where?

I think a turbo kit for this would be a little hard to do because of space. But, who wouldnt want to be pushing 600HP with a shot of N20? Since Im goinig to tear the heads off and clean the engine, I might as well swap in a cam, lifters, pushrods and rockers.

Well these engines are relatively easy to come by... What if this one blows up? Transfer the aftermarket parts to the next one, drop it in the jeep and take off.

you don't need n20 to make power if you went boost

and you can do a rear mount turbo if needed to be

Are they the same setup just one is at the rear? How does that work on a rig that goes through water?

Rtv and hope it doesn't leak?

My jeep is a road queen. Mud really isn't my thing as it gets everywhere and tears up everything.

Now, I had some fun today.

The one that is clean is vented right or are they both vented?

They both are vented. The clean side is the side with the head gasket seepage. That's why I wanted to know if it would be indicative of a head gasket leak. When I get around to putting it on an engine stand and drain the oil that should give me some clues to this head gasket issue.

Wiring for the most part is done. It's not bad. Il post up some pictures of what I did to it.

Cleaned up the water pump. I'm clueless as to how to get it to look like it's actually aluminum.



Here is the finished valve cover look...



And here is how the engine looks now.



Change of plans with the cam idea. I don't think il be doing any internal engine upgrades. Just don't have the cash and with the rate of me getting $90 a week and about $40 of that being saved, it's useless. I ask for more hours, I don get them an get told we need to cut hours. That's funny, my boss and the guy under him work every day when both of them being at work getting paid at the same time is not needed. It's bullshit. This swap will take forever to get done just swapping this thing in, it will never get done if I want to spend $1k on a cam, springs, lifters, and pushrods. I'm sure you can understand my frustration of working 12 hours a week making $8.50 an hour before taxes.

What's the rubber hose that comes from the block to the intake?

There's an exit for whatever it is too. What's it do? Is it needed?

cam swap isn't that pricey

I ran stock pushrods
LS6 springs for 60 bucks
thumper cam for 390
keep your lifters

I keep rpms to 5300 rpms for rev limter since this isn't a motor I beat on there isn't a need for the new hardened push rods that I run in my other motors

you can find cams for less money and depending on lift you can stay with the stock ls6 springs

Update. Took off the left head. I vacuumed he crud out of the cylinders. The head is not recessed so I will be able to use the mls gaskets. Problem. There are bulges in the cylinder head where the water runs through. Not exactly sure what that means. A little that on that one exhaust valve. But it's surface rust and I pretty much wiped that off with a paper towel.

Here's some pictures.
