Spare 4.2 engine?

It is much better that they found the problem before giving it back to you and letting you run it for 1,000 miles and then finding you have a much worse problem with it.
I know it is frustrating, but I would rather they took their time now so when the engine does come back it is 100%.

also what is wrong with it?
Low compession cylinders 1&2 - full list of hat was required when stripped was provided earlier.I did not mean: "why did it need a rebuild in the first place?"
Are you (they) saying the rebuilt engine has low compression?!

Truly feel for you and your P&J mate. Gets harder to remain objective on it, but you'd loose a lot now if you sold it as an incomplete car.
Like you said they need to explain why now it has low cost compression if you've installed new liners etc. I suggest you start getting answers in writing from them.

Low compression was the original fault, it's got something else wrong. I'm trying to get the full story but of course Easter is another delay.

Just venting at all the disappointment...

Exhaust port covers, but no intake covers - weird
Any description of the work done and the issues encountered?
To be fair it as all wrapped tightly with clingfilm which was removed to look at it.Any description of the work done and the issues encountered?
New large main bearing crank with associated machining etc, aux shaft upgrade, converted the front crankshaft oil seal housing to the later type as the old pulley adaptor had fretted on the crank nose as the bolt had been loose with the washer missing.
The cylinder heads caused issues as the casting was oversize and oval for 2 of the valve guides, it's sugegsted these must have been loose for most of the engines life. Two of the guides fell out when the engine was dismantled.
Then it's new everything else, camshafts, valves, everything uprated to the latest spec etc.
However it's the same price I paid for the car 11 years ago...

Am I right in thinking you treat the engine gently - no track days, drag racing etc?Do you know which cylinders and which valves were affected?
Since it was suggested this was long standing, are they saying that there was no other fault that might have cause the valve guide failure?
It would have been good to see photos of the remedial work on the heads

The car has always been warmed up fully before any spirited driving was attempted, even on trackdays. A few gentle laps, building up before giving it beans.
It's always serviced every year just before MOT even if the mileage was low, sometimes only 2-3K a year. I had no indication there was anything wrong as the engine was strong. It was discovered to have slightly low compression on cylinders 1&2 when it went in to have the coils replaced, following a misfire from a very wet weekend in Wales.
Engine was just under 60K miles.

It must be fantastic to have it back.
I hope fitting it goes smoothly and you get to drive it soon.
I'm away in a week, so it may be a couple of weeks before i get it back. I'd hoped for this weekend but that would be a rush and I'd rather not a rush job, not after all this time already.I hope fitting it goes smoothly and you get to drive it soon.
