October 2011 (Update)
Time for an update...
Having had the ITB's balanced and a new two-piece filter fitted, things are finally looking up in that department. It's running a lot smoother, fuel economy seems a little better and (in my opinion) it just looks better. It also seems to be much better made than the "filter of death" I was running previous and it even sounds better. Here she is:
Please excuse the cr&ppy driveway shots but I'm trying to keep mileage to a minimum until I get the outstanding issues fixed.
Here it is again.
And again.
However, it's not all good as you'll no doubt know if you've had the time, patience and/or inclination to read my previous posts! First of all, the engine seems to be breathing very heavily. This is quite concerning and obviously I'm keeping an eye on it. I will likely fabricate a simply catch-can and cable tie the breather pipe into it to see just how much is expelled. In the meantime, here is how things currently look. The gunk and oil you see is from the last month or so (since I last cleaned it). As you can see it seems fairly bad (at least in my - admittedly inexperienced - opinion).
Hmm, ok - perhaps the image (above) doesn't seem that bad having just looked at it again but I can assure you the amount of oil coming out of the pipe is more than I've seen on any other healthy-running vehicle.
Also of concern are the oil leaks. These have become progressively worse (not that I'd have expected them to miraculously fix themselves) and thankfully a chat with Matt at TDF means that my Trophy will soon be back with them to be fixed. They have had my car before and know it well so hopefully the guys can do their stuff and she'll be back as good as new. But... I have a nagging suspicion that something else is not quite right but I can't put my finger on it. Here are a few shots of the leaks. Not particularly exciting but we're all petrolheads here... These were taken after a little bit of a mop up.
You can see the oil starting to pool in places. And it's making a mess on my driveway (albeit only a small amount).
As mentioned above, I feel that there's something not quite right when driving it. It handles better than ever (thanks to the damper rebuild recently) and fixed engine/gearbox mounts but the performance isn't what it was even a handful of weeks ago. Of course, this could well be related to the leaks and/or other issues...
Thankfully my good friend set aside an hour this morning at his family garage so I popped down to get a compression test done. I suspected I was down on cylinder pressure (as I was when all the problems started way back when) hence the visit to my mate's garage. We broke out the testing gear and the results were... disappointing... I think the following image and overlay I made shows the story of this morning:
To put the above into perspective, when the car left TDF last time it was running around 190 PSI across all 4 cylinders. I guess that's where some of my performance has gone then! I also found that my spark plugs (especially spark #2) were now swimming in oil. This was new as they weren't the last time I had them out.
Having dropped a small bit of oil in through the spark plug opening the engine was cranked again (wet test to see if maybe the piston rings were worn perhaps). This yielded a slight increase in pressure but it was hard to say whether or not this was coincidental; in the end proving inconclusive. I hope the pistons are ok otherwise I fear it is going to get even more expensive.
To finish this update, I'll post up a few images of the driveway showing my 'backup' car. It's some piece of Jap thing. Maybe if I ask nicely my good lady will let me borrow it for a while. Talk about a downgrade... (runs for cover!)
Roll on next week and making the arrangements to get the Trophy to TDF.
