116/3328 VYA engine rebuild

Here's where to post photos of your cars. We all want to see your Jensens!

After 180,000 miles my Mark 1 needs an engine rebuild. It was starting to run hot and was becoming very difficult to start and although it still seemed to pull well when running it had low compression on at least one cylinder. In addition there have been ignition problems for a while which is perhaps not surprising given the various tweaks to the wiring over the past 47 years. I have virtually full history on the car which shows no major engine work and the engineer working on it believes it has never been apart.
Below are pictures taken at Appleyards with the engine out. The engine requires a new crankshaft and two connecting rods as a result of wear from the crankshaft moving about (the car is a manual) in addition to all the usual machining, bearings, etc. Several piston rings were also broken.
While in Appleyards I have had the engine bay tidied up and a new wiring loom fitted and I will eventually have a new wiper motor, uprated alternator and re-cored radiator installed.

Hopefully all that should be enough to get us to Turin and back in June. Thereafter she will be going in for a bit of bodywork as there a bubbles on the wings, on a wheel arch and on the tailgate and the sills have a slightly corroded quality to them...

Also attached is a picture of the car in one piece in the car park of the Amsterdam Hilton a couple of years ago. This was the hotel where John Lennon and Yoko Ono had their honeymoon "bed-in for peace" in 1969 - same year as VYA was made.

Finally, and for amusement only, pictures of the mouse house toilet behind the dash taken last year. The little fellah had spent the winter of 2014/5 peeing on my radio and consequently it wouldn't work. The car was also very smelly...

It's for the clutch Gary as they are Manual Gearbox interceptors :wink:

You know I was thinking perhaps its something to do with it being manual should have realised that it was the clutch fluid :D

Rebuilt engine back at Appleyards... looks great, lovely stainless bolts and brass coreplugs, uprated alternator and new petrol pump fitted. I realise the rocker covers should be silver but apparently the engineer paints everything black... and after some discussion we all (Andy, Kevin, Elaine, me) thought they looked pretty cool in black, and I guess it can be seen as a sort of signature thing!
Apparently the engineer thought this was the worst engine Andy had taken him which is an achievement of sorts I guess! And since the engine was probably made in 1968 (the car was registered April 1969), has done 180,000 miles with only routine servicing and was pulling like a train until last year I can't complain!

The original crankshaft looks like it might have been machined rather enthusiastically in the past... first pic shows machining with normal enthusiasm (in the middle of the shaft) and the second pic shows the results of the extra enthusiasm shown towards the flywheel end... since there is no evidence of any previous engine work there was speculation that this had been done in the factory? Still, as noted above, it seems to have survived for 180,000 miles!?

With all that wear "several broken rings" etc what a testament to Chrysler design.

The car looks great Mark and pleased to see it is still used and maintained properly. If only all Interceptors were treated like that.

Hi Mike
Thanks! We love the car and hope that the work on the engine (and body - we have it booked in for some restoration in July) will last us at least another 13 years and so bring us up to your 27 years of ownership! The restoration work that Cropredy did for you over 30 years ago has lasted really well considering the mileage and the fact that we have left it outside and used it in all weathers.
I have been looking at the old service records and can see that following complaints about transmission noise at about 19000 miles, and some correspondence between the first owner (Mr Weedy) and Jensen, a new flywheel and clutch were fitted by a firm in Bristol in November 1970 (all for £451) and I wonder if that was when the crankshaft was also attacked since there is no mention of the engine being removed from the car. At the time Mr Weedy was saying that he had been driving fast cars since acquiring a "J type MG" in 1932 and that he had never had "a load of trouble like this in the whole life of a car, regardless of price, let alone in a £5000 car only 18 months old!" Although Mr Weedy points out the car was out of warranty he thought Jensen should have something to say on the matter and it seemed that they agreed to consider a contribution to the cost of the repair if the original flywheel was returned to them. It looks like Mr Weedy sold the car shortly after as it changed owners in 1971 and it is not clear how the matter was resolved.
Given that the car then carried on for another 160,000 miles I wonder if Mr Weedy was a bit hasty!
In fact, on re-reading the history, I have been reminded that the car had a speedo swap at 10,000 miles so it has probably done over 190,000 miles without any other major engine work, not 180,000 as I first thought!
Regards
Mark

Engine re-fitted and back on the road with full MoT! So far I have done 450 miles in "run-in mode" (i.e. keeping revs below 3000 and being gentle with the throttle) - but what a transformation it is like driving a normal car and quite relaxing!
Power difference is marked as is the willingness to start - what a wonderful thing engine compression is - though no doubt the new carburettor and wiring loom are doing their bit! It accelerates well through all gears even when used very gently so it will be interesting to see how it performs when fully run-in and unleashed!
With the new radiator it is now running at normal temperature and last week coped brilliantly with a 1 hour rush-hour crawl through Nottingham in the rain without going over 200F and, more importantly, without making me anxious that overheating was imminent. In addition the new 90 amp alternator meant it also stayed slightly on the 'C' side of neutral on the ammeter throughout - even with the lights, wipers, engine fans, interior fan and radio on and again without making me anxious about discharging the battery and without having to keep the engine revs up and thereby increasing the risk of overheating. A new wiper motor means I can use the wipers without them running out of steam and getting stuck half way across the screen - amazing!
It also looks very smart!

In addition to all this Kevin at Appleyards performed some emergency repairs to the bonnet hinges which had started to come adrift with the all the excitement. Picture is with bonnet off being repaired.
As is probably obvious I am really pleased with all this and would thoroughly recommend Andy and Kevin at Appleyards - they have been very patient, have done some great work to a tight timetable and are very generous with their (interesting) tea!
