I posted much the same thing as part of my ongoing thread
in the Images forum but I thought I'd repost here as I thought it might be of more interest to fellow JTSers.
So, at 107,500 miles exactly, it broke down for the first time (in my few years with it, anyway) a few weeks back. The alternator gave up the ghost, which led to the question 'how far can you drive without one
', and the answer being - with a liberal application of Rainaway and a heavy right foot - at least 40 miles.
The alternator is buried deep in the engine bay and access involves either dropping the subframe or dismantling the engine. This and the impending cambelt were the final straws that pushed me into Stupid Plan #1, rebuilding the engine. A perfectly working engine. Well why not, since you save about three hours labour?
There is reason to this, but that can wait. Here's an engine, or at least the head - didn't do rings as it's not burning oil and the bores are OK.
As you can see, the JTS loves smothering itself in carbon build up. It can't get enough of the stuff. That's early and for all I know current direct injection engines for you. Wonderful.
Well happy days, because here's afterwards:
All the pictures are here: Index of /crap/jtsrebuild
What else? Well the injectors were also refurbed, except it's only been 40k miles since they went wrong, with use of injector cleaner in between, and they were fine. Since they typically go properly wrong every 50k-70k, using cleaner and giving it a regular Italian tuneup might be a bit of good advice to fellow owners, or it might be useless.
As well as that, the aux belt tensioner was knackered, the flexipipe in the exhaust was knackered, and obviously the alternator got fixed (twas the voltage regulator). It also got a new phase sensor, new sparks, new water pump and new variator, new balance belt and tensioner.
Now I have to run it in sub-4k revs for a little bit, so can't be sure of the benefits straight away, AND my expectations are a bit skewed by having been driving about in the 2.4JTD version of the same for three weeks, AND I was driving about in a noisy car before because of my failing exhaust.
The first thing: as Bjork once put it, IT'S OH SO QUIET. I can barely believe how quiet it is. It's also smoother, and I believe has better low down torque with less of a flat spot. As soon as Southways let me, I'm going to get it dyno'd again, and hopefully the results will be a bit nicer than this slightly lumpy thing
from a while back. We shall see.
What was the point of all that? Well, once this fairly large bill is out of the way and some more money cobbled together, I'm going to engage in Stupid Plan #2: off to see Alfatune oop north and get a new exhaust - Supersprint manifold, sports cat and full stainless system - and a remap. The aim isn't really about power per se, but that might see 180+bhp from something last known to be burping out a rather weak 145. And who knows, it might be noisier again
Finally, all of the above work so far has been done by Laurence at Autolusso Bournemouth
, who has been excellent to me and my car both on this occasion and many in the past. Very much recommended. Thanks also to Jamie Porter of Alfa Workshop who got us a JTS flexi in a hurry.
