Hello, i wanted to post up my 03 discovery that has been sitting for 2 and a half years dues to a slipped sleeve. instead of replacing the head gasket for a 2nd time i knew my liners were slipping so i went with cannibal v8 top hat inserts. i opted for the full long bock with the beefed up cam and valve stems cut accordingly. i knew the sleeves were hosed because i've had the famous ticking sound for about 60k miles of this trucks life. with that being said here are my pictures.




getting the old one out





you have to send cannibal v8 your front cover so they can rebuild it with new springs and relief valves


and i got some help

I'm pretty sure I just worked on a Disco at the dealership which has about 10k miles on one of their motors. The head gaskets are leaking coolant pretty heavily. The company wanted us to pull the motor and mail it back to them so they could inspect it to see if it is covered under their warranty. I'm not certain if its the same company, but I do remember it being from Oklahoma and having studs instead of bolts for the heads.

Also, what is with the goop on the head gasket and why is the aluminium block painted?

Thinking the same thing. Maybe they goop it up to slow down the coolant leak?

I forget who I was talking to (dealer tech) but he said they had issues with freeze plugs falling out of an AB short block.

I've put in a couple AB blocks, and they seem to be the nicest I've done at the dealership. We got two bad ones through Land Rover. Both knocked and one had oil pressure issues.

The grey stuff looks like "pro-seal". The black stuff on the heads???? Never heard of using sealant with head gaskets. Am I wrong?

With all the past controversial car cannibal experiences, keep us posted on how the "new" cannibal performs.

Studs seem to be really popular, I still use stretch bolts.

Because of where I work I won't say anything bad about any other engine supplier, but I've had customers with 2 bad blocks in a row from the same supplier.

(labor isn't cheap)

here are some reasons off the top of my head

cars that had aluminum heads and studs have a retorquing schedule, ARP does not
TTY bolts are now used by everyone in the auto industry
I've never heard of a failure caused by the bolts
I've seen stripped threads in 215 blocks that used studs

Those are pretty much all of my reasons.

I also use TTY bolts every time, if you know what you are doing it is not a problem.

Shellac on the head gaskets? LOL Cannibal strikes again

Makes sense. (though the ARPs I used on a VW head DID have a retorquing schedule)

even if there was a retorque schedule would you want to do that? Pulling the valve covers is a pain in the ass on a 95, and only gets more complicated as they get newer.
