Dreaded Engine Knock

[EdinGuy]

Had my car only short while but it's developed a knocking sound, don't have the area to investigate myself but from the mileage (103k) and scoping forums I was given a few suggestions at what it could be

Took it to a garage today and they've done an investigation basically said it's not good news, they believe there is two knocks and have quoted up to £4-5k to get this fixed. Basically issues around the timing/valves/pistons

Would I be better looking at getting a refurbished engine for them to install?

Have you priced up a recon engine or a secondhand engine yet

[EdinGuy]

No not yet

I'm incredibly undecided what to do, flipping between selling it and getting another car or doing some work on it myself, such as replacing the cylinder head with a new one with new valves etc either built for me or building it myself from the parts.

But that would then leave the second knock which I heavily suspect is the DMF still

[EdinGuy]

So this is what I'm trying changing to at least get the valve issue sorted
