Jaguar F-Pace Non Runner

Fit it and keep it. You've done so much already, should be quite familiar with the engine by now. Your wife loves it, I think it's worth one more go to get right.

You are clearly a masochist

I know I'm a masochist too but I'd have flogged it after the last issue.......................

Me? Well I have owned a TVR for 20 years

This has certainly been a fascinating thread, some excellent skills shown by the OP, and I hope something goes right for him with it soon.

That makes you an astute purchaser in my book

But for fun I’ll raise you Opel/Vauxhall (that like to fizz for fun) and I was silly enough to buy one that had a makeover in a Norfolk shed……

I’d have still got shot of the OP’s car well before now

Pounds like a very sensible plan. The BMW looks reasonably tidy from the shots.

An unfortunate typo there...

I promise that was a typo!

I had a result on Friday. The BMW passed it's MOT, I didn't need to do anything to it. So the wife is back on the road and the immediate pressure is off.

I started stripping the Jaguar. I took the gearbox off Thursday evening, it didn't take long, a couple of hours. I know my way around this pretty well at this point.

I couldn't get to 3 of the flex plate bolts do the torque converter as the engine is locked so it had to stay on.

I moved my attention to getting the cylinder head off. I removed the cams, all the valve springs looked the same height, no obvious sign of a bent valve.

I took the inlet manifold off and noticed metal on the port, mainly on cylinder 1. Not good.

Cylinder head off. It's not looking good.

Opinions welcome on what's happened here I've not seen that many mashed up engines before. It's done 10k since it was rebuilt. The block did have a couple of liners fitted (don't know which cylinders) and then everything was bored out and I was using aftermarket pistons. Jaguar don't sell larger pistons so bored out liners aren't something that's an approved thing. You can see the liner has dropped and the piston ring is above it. So I'm wondering it it dropped, the ring caught it and it then that mashed up the piston. I can't see how the ring ends up where it is otherwise

It's always been a bit noisy and it seemed to use a bit of oil, the crankcase pressure seemed to be a bit high also. Maybe this failure was on the cards all along?

Moving forward, that's the whole engine totally finished now, no prospect of repairing it (if it was a couple of bent valves I was tempted to). When I calculated what I'd get breaking it I'd made a few assumptions on some engine parts being alright. I'm probably looking at around £7-8k back now if I strip the car for parts. It's a shame to do as there's nothing wrong with the rest of it.

I can chalk this whole endeavour up as a big fat L.

Looks at pictures

Looks back in the thread for description of latest FTP

It looks like part 3 is coming up. My wife rang me to say it had conked out. She described it as a single crisp packet popping noise and then it slowly cut out and wouldn't start. It wouldn't turn over.

Does not compute……………

Stripping and binning that car off will be quite cathartic. Although a loss it's definitely the best option. What a complete and utter turd of an engine.

[PRO5T]

Really disappointed for you Ecsy.

Would imagine so.

[RicksAlfas]

What a mess! How can a liner drop that much? What supports it underneath?

[Escy]

Another photo now I've cleaned up the piston.

Maybe it ran on 3 cylinders. She also described it as she thought something had come off under the car. I don't hold too much stock in these descriptions.

You need a local flood and an insurance policy

I saw you post that on the wrong thread and was about to ask what the cryptic clue was supposed to mean.

All now is clear

[CarlosSainz100]

I read somewhere that there are places where you pay them to smash up a car. The sort of thing stag weekends do.
Flog it to them. It would be quite cathartic to see it get a darn good thrashing.

[I-am-the-reverend]

The liner has slipped down, and the lowest piston ring has caught it and dragged it down.

What an absolute pile of st.

British engineering at its best. If JLR designed a pushbike it would have square wheels.

New liner and piston, get it running and down the road.

[ChrisCh86]

Wow.

What an epic fail considering the huge amount of time you've already put into this.

Time to sell it for bits, separately (for the most money)

Or you could K swap it? 😉

That appears to be a failure of an aftermarket liner/sleeve.
