i cant think of aanything i would rather have less than a cabriolet, except possibly a facelift cabriolet, or possibly a 6cyl facelift cabriolet X(

"dont know what the exact problem is but do know that it can be repaired. does not need overhaul or new engine!"
that part made me lol the hardest.

Not quite a turd, but it would have to be free. And I would have to be in the mood for a serious project. You just know there's all sorts of stuff wrong with it...

I envy you guys. I was looking at a running version of that car for $30K on Aussie ebay today. I've got 3 usable 4.0 motors sitting in cars in my back yard.

you could take two of them and join them together at the crank sha.... wait.

look, its got a power bulge on the boot lid, as well as the bonnet. i often have that problem; too many power bulges.

I'm sorry fellows, You may have misunderstood me. If i had had the opportunity to buy an XJS convertable for a $1000 I would and i'd buy several more. $1000 cars usually have issues so it pays to have parts (which I've got). I own 11 Jaguars (2xMK10 7xXJ40 2xXJS - 2 cars are dedicated parts cars) and extra parts.

Forgot to add, and it has been brought up many times while I've been a member of this forum. There is a huge difference values over the world. Cars have value, you just have to pick the right market.

So he dropped a valve seat. But at least it doesn't need an overhaul!

It's so easy to fix tap arm problems.

Notice no pics of the engine so you can't see how the wiring is all boogered up.

This car looks perfect for a low mileage AJ16 drive train and ECU to be dropped in. If one invests enought time and patience , a full Aj16 drive train can be found for another grand

Evidently this guy's car has a tap arm. I was wondering myself how hard they are to fix, but evidently they're pretty easy according to him, and look how good of a mechanic he is!

I always called them valve seats? The seals would be the umbrellas or o-rings (depending on the car).

the valve seat would be the part of the head that the valve actually seals against. when you have a valve job done, they resurface this part of the head so that the valve seals properly and you get lots of compression back.

the seal would go around the base of the valve stem to keep oil from entering the head and smoking out the exhaust pipe.

unless im missreading your post and the valve seat is actually what drops. ive seen dropped valves, but i had no idea you could drop a valve seat.

holy cow! i just googled dropped valve seats. i had no idea that the valve seat was an insert instead of just being machined into the head.

On alloy cylinder heads and many cast iron heads the valve seat is an insert which is interference fit into the head.

It has been that way for many many years. The dinosaurs like the small block Chevy had surface hardened seats which were only good from the factory. If you grind or cut the seats they need to be hardened again. Most SBC performance shops bore the head for a Stellite or hard seat.

Yup, somewhat common on our engines since the seat is a dissimilar metal from the aluminum head, when overheated the seat works its' way free and drops due to the differing thermal expansion on the two metals.

people from cold areas, generaly dont but convertables or open top cars, but in sunny warmer climates they sell quite well.

thats the way its always been ,and will continue! just look at what movie stars drive.

and that OP car is well worth it, like said, probably get it for $1K. and drop in a V12,with a 700 trans.

just go to a car show and see how many open tops there,.
