Discovery 2 Head gasket/ Fire ring failure.
Hello All, I am currently a new member to this forum and I am seeking help on my Disco.. But aren't we all?
Anyway, Two years ago I acquired one of my dream cars/ suv, a 2000 land rover discovery with 100,000 miles (currently has 150k), the engine had a head gasket failure and I got it to fix up and use as a daily driver. My grandfather and I Pulled the engine out and sent the engine to a land rover shop in a city near us. Portland Oregon.
The engine was fully rebuilt top hat liners and all new valve train, pistons etc..
Well, about a week ago it started with a sound that was similar to and exhaust leak. I made an appointment with an exhaust shop to have it repaired. well before the appointment I continued to drive it around and then one day before the appointment it got very loud. and the engine bay started to have a smell of exhaust so I parked it for the day. I drove it to the nearest exhaust shop to me about 100 miles away and they pinpointed the leak as coming out between the head and block near cylinder 4 no coolant loss or overheating no oil burning plugs look very clean . I Have ran compression tests for each cylinder in order : (Cold test, no startup for 24+ hours)
Cylinder/ Reading
1 /179
3 /180
5 /180
7 /181
2 /181
4 /100
6 /182
8 /180
I like to think that I am somewhat mechanically inclined for an 18 year old. I've done timing chains, water pumps and other simple things on other engines but I've never once done head gaskets I have however watched my grandfather work on his Oldsmobile Bravada and do heads on that... and I'm not to worried about tearing into the engine I know to label bolts and take lots of pictures but I'm scared of what i might find. I heard the exhaust gases can etch out the block and head and I don't want to have the worst heartache of my life from trashing a $4,500 engine rebuild in 50,000 miles..
Any input and help I could get would be greatly appreciated.
(Sorry for such a long thread, Trying to give as much info as possible..)
Thanks,
Gage

From what I have read, the OEM gasket is an all metal gasket and is prone to failure, whereas the composite is a layered gasket. The Fel-pro is a multi layer steel(MLS) and designed for engines like ours.
On another note, I am a firm believer in using ARP studs in conjunction with these gaskets. I know there are mixed feelings about the studs, and I respect their opinions. If and when mine need replacing, studs will replace the head bolts.
