Default Head Gasket Repair!!!!!!!!!!!!!!!

Hey all,

Unfortunately I have the dreaded head gasket issue on my 2000 disco v8. Can't really complain, the beast has been the most reliable vehicle I have ever owned. I have spent very little on repairs and but a few dollars on matinence.

The beast has done 250k and the gasket has finally let go. Leaking externally
only on the left side just below the first sparky closest to the firewall. Not a bad leak but enough to become a bigger problem if let go. No coolant in the oil and the engine is still running like a dream.

I have read many of the posts on head gasket repairs and they have been helpfully as usual but a bit short on info regarding the exact parts that should be replaced. Obviously I will order a head gasket kit with all the bells and whistles?
But the vehicle has done a few miles now and will probably need some other parts as well.

My question is if you had the chance what would you replace while you have the heads off!!!!!! Push rods etc etc etc. I would only want to do this once and I think that i should attend to other issues while in there. Any help would be greatly appreciated!!!

All the hoses. t/stay, cam and lifters, timing chain set and oil pump along with a valve job.
Considering buying your parts from P.T. Schram, his number is listed in my signature section.

Thanx Mike. I've got most of those parts in stock or will sometime next week.

I do have the headsets in stock, complete with bolts. DII, $225 shipped CONUS. DI, $200 shipped.

I think I'm down to only five sets right now though but will have more early next week.

Thanks mike and PT, being in Brisbane Australia I"m not sure whether it would be economical to buy from US but i will price up anyway.

The recondition costs for the heads are $620AU which includes valve grinding
and machining the head. The engine shop said to leave the camshaft and lifters alone and replace the pushrods and valvetrain. Do you agree!!!!

The headgaskets were leaking oil and water front and back of engine. The gaskets were the new version and not the old metal shim. Does that mean that
they have been done previously or are they standard issue for a 2000 model.

Cheers
Andrew

Andrew, Rovers are know for having soft/failing cams, we rarely ever loose a push rod or rocker arms, sorry, they don't know what they are talking about.
All D2 came from the factory with the new style head gaskets.

Thanks mike, I would rather take your word rather than the machine shop. I have inspected the camshaft and noticed some surface damage or pitting like gravel markings if that makes any sense. The same wear is on the bottom of the lifters. I will be changing the timing chain and sprockets anyway so I will throw in a new camshaft as well.

As for the head gaskets I found out that they were standard issue after 94. The head had not signs of warping using a straightedge. Do you think machining should be standard or can I give this a miss and save some cash if they are straight and true! I will still have the valves serviced of course.

Cheers Andrew

So, if you are going to replace the cam, and I would, consider replacing it with a 4.6 after market cam, it will give you more power and low end torque.

I always get the heads milled true. Straight on the bench and straight hot, when torqued down on the engine are two different things. You may be able to get away with it but it would be a real heart breaker if it were to fail again to save a few $$ in machining costs. It's not expensive (well not where I live anyway) so I never risk it.

PT, that's a somkin deal on a HG set. I may be placing an order soon myself. Do you ship International?

Shipping to Canuckistan is a HUGE PITA. Add $35 for the paperwork and additional shipping.

It really is a pain in the ass to ship to Canada, worse than any other country I've shipped to.

I'm going to be changing the timing chain and sprockets in my 2000 DII sometime soon (116k miles) and have started to think about swapping cams. So far, I've seen a couple of the 4.6's that state they fit 03-04 DII's. These will still fit a 2000 4.0, right?

Yes.

I can usually have them in 48-72 hours.

I've sold many 4.6 cams to 4.0 owners with great success.

Thanks, PT. My guess is that I'll go with yours over the AB cam. Once I get closer to the project I'll let you know.

Shit.

Good thing we have that NAFTA, not the first time I have run into issues shipping stuff up here from the US. Damn Cows cross the border fifty times a day but when a guy needs a few auto parts suddenly it's an international security risk......+tax.


Thanks anyway.
