Hi. Looking at a '66 Mustang with 289 V8 - there is a distinct 'tapping' noise and mechanics believe it might need a top-end engine rebuild.

Two questions:

1. Has anyone had anything similar who could advise on ballpark costs?
2. Any recommendations for where to get this done? I'm near Crawley, West Sussex.

Many thanks.

Check the exhaust manifold gaskets and nuts are tight, a ticking noise is common with a small blow around the headers/head seal.

The word 'rebuild' covers a range of things, from blueprinting things to better than new, down to only actually renewing bits which are broken or going to fail imminently.

It's very expensive to renew everything.
The minimum is probably a gasket set and a few small parts, plus labour.
The minimum might get another 50,000 miles or more out of an engine. Or not.

How far do you want to go when you find parts are not 'as new' but still 'OK for a good while yet'?

I could probably live with a small ticking noise if I understood it didn't mean the imminent failure of something significant.

^^^This.^^^ First thing to check before you worry about spending any money. Really does sound like a noisy tappet.

Mustang Workshop run by Roy Holmes if you want top level work. He’s at Fleet on the M3.

Or Phil King up at Waltham on the M25 - another top guy - built the 347 stroker in my old fastback.

Google them. Likely just manifold though as has been said. These big old iron things are great to work on.

Presumably you've ruled out the manifolds as it was suggested you look at those in your previous thread?

What do you mean by top end rebuild? A couple of years ago I had Real Steel replace all of the guides and reface the valve seats in my heads and then I built them up with new valves and gaskets, so I can go back and look at what I paid for that if it helps? Obviously with a tap you might be looking at a new cam and lifters as well which involves a bit more strip down (water pump, timing cover, etc. off), but is also an opportunity to put a better cam in which helps these engines massively. I'd suggest you get a proper diagnosis as these are simple cars and any decent garage should be able to help. It is unlikely you need a new cam/lifters and the cylinder heads rebuilt, so knowing which will save you time, effort and money.

I bought my first Mustang from Roy in 2001 - a red '67 coupe with literally zero rust. He's a great bloke.
