Cylinder exhaust valve repair cost
Discussion
A few weeks my Kia Sportage started to loose power. I took it to the garage they did all the standard stuff, coils, sparks, etc., as well as a compression test. Nothing in cylinder 3. They didn't want to go any further so I took it to another garage who confirmed a burnt exhaust valve in cylinder 3. The advice was an engine replacement costing £4k. I then had a conversation with a specialist engineering company who said that they could repair the head. It's a standard charge of £495 to receive the vehicle, remove the head/engine, diagnose and cost for repair. Now, the issue I have is that I don't know what we're talking roughly for a valve repair so I'm hoping someone can give me a bit of an idea as the mechanic from the specialist engineering place is keeping his cards close to his chest. The car is currently worth around £5k in the used car market. I don't particularly want to put thousands of pounds into the valve repair option. Thankfully for any info, thoughts, experience, advice.

I thought it was the bottom end on these, rings and worn bores ? £500 to remove the head, refurbish it and put it back together with new oil, coolant, head gasket set and bolts, new chain kit is stupidly cheap ....
It's 500 quid to recover it, strip down and quote. No fix.hidetheelephants said:
A replacement valve shouldn't be much, even if they're taking the mick £100 tops; the rest is a gasket set and maybe lapping the new valve in if the seat has been marked by the damaged valve. OE gasket sets can be expensive if pattern parts aren't available, potentially £2-300.

This is all really helpful.
I think what I'm hearing is that it's potentially going to cost less than 1.5k.
I'd take that with a pinch of salt. Most PH finger in the air estimates look woefully low to me as these do.I think what I'm hearing is that it's potentially going to cost less than 1.5k.
I bought a complete reconditioned head for s Td5 Discovery and it cost £600, diy'd fitting though.
That's the conundrum. I'm cool with paying the 500 to get the head off and a diagnosis but it's what comes following that that's creating the uncertainty. If I knew it was going to be less than 1.5k I would have it done tomorrow. I've asked the mechanic for an estimate based on different scenarios and I'm waiting to hear back from him. This will hopefully give me an idea of price range. I feel confident that if it's a valve repair/replacement I'll get another 3-5 years out of the car.
I'm going ahead with getting the head done. The unknown aspect of cost is terrifying, not gonna lie. To make that feeling worse someone said to me last night, "The head is usually given a complete valve job at the same time as replacing the dodgy one because the rest of the valves and guides probably need attention, too. If one exhaust valve has failed, the rest are probably on the verge of failure if they haven't already started to leak." I did not need to hear this!
Anyway, we'll see what happens. £495 gets it disassembled and diagnosed. Hoping for no more than a grand on top of that.

Having done all sorts of jobs like this in the past, the big unknown is the head repairable.
It more than likely is but be aware they could find the head cracked or even burned away from the exhaust gases, indeed the top of the block might be damaged too where exhaust gases have burned a channel, there could be visible bore wear too, it might be repairable but before you go ahead maybe have a look see what the used engine market is like, so if the present head/engine is scrap you've already done the searching and have a used engine or two pencilled in.
Obviously best if the garage doing the job source and supply a used engine if needed, if you supply and it proves a dud you still have to pay for all the labour involved removing the dud and fitting another.
