How clean is my engine?
Some important info on gasoline. It seems that Costco, Shell, Petro, ESSO have the extra additives, whereas Ultramar does not. As for Pioneer, Drummonds, & Stinnson, depending on where they source their fuel.....who knows.

Buying a Car
Phil had recently purchased a MK2 Jaguar with a 3.8 L engine and standard transmission . He is planning to do some maintenance and minor reatoration on the car and described the things he looked for both before and after he bought the car. The car had been carefully looked after in its early days but has several problems now. The seats need to be rejuvenated.more of that later and the body needs a fresh coat of paint. One of the first things Phil did was to clean away all the crud in the wheel wells to determine if there was any rot in the inner fender panels. He then checked the interior and found wet carpets and a stain next to the rear window. He caulked the rear window rubber that was in good condition and ordered a new rubber seal for the drivers side quarter light window. The carpets were tired and he has ordered a new set. He will clean the floors when they are out. Mechanically the car is in good shape. Based on previous records it seems that the hubs and wheels are new (wires) and an inspection showed only one loose wheel due to a wheel bearing that just needed tightening. It was clear that despite the quality appearance of the car that after close inspection there were a lot of little things to be done to make it a good driver. A careful inspection of brake lines, hoses, electrics under the car and in the engine compartments and the condition of all fluids is essential. In particular checking the fluid levels in the transmission (standard or automatic) and the differential is essential and the greasing of the many grease fittings. Most older Jaguars have a maintenance diagram. DONT TRUST YOUR SERVICE STATION TO CHECK ALL THESE ITEMS...DO IT YOURSELF!

Saturday 5 September, Phil Karam hosted a Technical Session at his home. The event had three components: what to look for when you buy a car, a tour of his collection with coffee and goodies and the steps in restoration of leather.

How to get parts into Canada by Phil Karam
This may be of interest to those who buy goods/car parts, from the USA, and have them shipped to Ogdensburg NY, and drive down to declare/pick them up.  In the past, I have used Rothel Parcel service, as well as the UPS store. I have just discovered a better location. It is a Canadian company.
The rate is the same $5 per package, however in Canadian funds.  You have 1 year to pick up the goods, rather than the 1 week offered at UPS. UPS normally has a 20 people line up, whereas this place seems to be unheard of. Best yet, when ordering tires, they charge $5 per pair, if wrapped together, rather than $5 each.
This allows me to buy goods/parts on sale and not of desperate need for them, until I find it convenient to make the trip.  They also do customs and delivery to Ottawa, if you are too lazy to get out of bed.
Lastly, they send you an email when the goods have arrived.  What more do you want?
For those interested, I would recommend that you sign up now, so that the account is available when you need it.
The warehouse is located in the duty free zone, just over the bridge. http://www.myusaddress.ca
 

How clean is my engine?
TOP TIER DETERGENT GASOLINE
Club Technical Director Phil Karam came across some worthwhile information about the additives in modern gasoline. Apparently over the past several years, the minimum level of detergent required by the EPA has declined by an estimated 50%. In response, seven of the world’s top automakers (BMW, GM, Honda, Toyota, VW, Mercedes Benz and Audi) recognized that these reduced detergent standards don’t go far enough to ensure optimal engine performance. The reduction hampers the ability to meet emission standards, leading to engine deposits on fuel injectors, intake valves and combustion chambers resulting in a big impact on emission and driver satisfaction.
Top Tier detergent gasoline has been produced to allow owners to avoid this lower quality gasoline. Current retailers in Canada include Chevron Canada, CO-OP, Costco Wholesale, Esso, Petro-Canada, Shell Canada and Tempo.

Winterizing Modern Jags by Rob Dunlop 
Most of the club members with older Jags (‘50s to ‘80s) already have a routine for putting their cars in winter storage. Phil Karam, our club technical coordinator, has detailed this several times in the Jottings. While the procedures are for the most part relevant to all cars, for modern Jags (i.e. those equipped with central computers/ECUs) emphasis needs to be placed in certain areas: fuel, tires, moisture and battery.
FUEL – modern unleaded gasoline, most with ethanol, goes “stale” quickly if stored over longer periods such as a Canadian winter (see Dave Kenny’s fuel article in the Jottings). To avoid start up and running problems next spring, add fuel stabilizer (Stabil etc) and top up the gas tank. Run the engine to ensure the stabilizer gets all through the system (I add the stabilizer before going to the gas station to top up…the run home mixes the stabilizer). Correcting a fuel problem on a modern Jag is not a DIY exercise (as for older Jags) and normally requires dealer attention. (NOTE: Phil Karam has a different perspective on fuel storage, preferring to run the tank low and topping up with fresh fuel in the spring. Our local Jag guru Rob Staruch agrees with the low level fuel tank but considers adding fuel stabilizer as essential, regardless of the fuel level. The difference between full and empty has to do with minimizing condensation with a full tank versus having a full tank to drain in the spring if the car won’t start…different strokes…)
TIRES – modern tires with wider profiles are manufactured differently and have a greater tendency to develop (and retain) flat spots when parked for a period of time, particularly on a cold, concrete floor. For storage, overinflate the tires to 45 – 50 PSI and park on pieces of old carpeting.
MOISTURE - I cover my whole concrete garage floor with an old tarpaulin under the carpeting to minimize condensation on the cars when the temperature changes getting into spring. Also to keep moisture at bay on concrete, Mete, the Bearr’s Motorsports chief mechanic suggests putting flattened cardboard boxes under the car to absorb the moisture, adding to the pile as boxes become available.
BATTERY- the high tech modern car is heavily reliant on a battery in peak condition. A fluctuation of .1 volt on a later Jag can result in spurious error messages (see Lyndon Mitchell’s article, Sep 09 Jottings. His ’97 XK8 was diagnosed with a $6000 repair job after error messages appeared. Lyndon changed the battery for $150 and the problems disappeared). Ergo, the battery needs to be tip top all the time. Personally, if my ’07 XK sits for more than two weeks (including over the winter) I attach a smart battery charger over the time period. Unlike a basic trickle charger, it samples and adjusts voltage and amperage according to the battery condition and is intended to remain attached over long periods of time.
(NOTE: Princess Auto has a highly-recommended CTEK smart battery charger on sale 3-15 Nov for $74.99 regular price $109.99)
ADDED BATTERY TIP: Always lock your modern Jag when parked, even at home in your garage. If left unlocked, the car assumes a standby mode and the systems can take up to 20 minutes on battery power before shutting down. Locking the car shuts the power down more quickly. A little care and prevention before putting your cat away for the winter will greatly reduce the risk of problems on start up and running come the spring.
 

TEMPERATURE RISING ? by Dave Kenny
There is often a sense that as XK six cylinder engines run hot, then cooler must be better. This short technical note addresses the E-type cooling system operating temperature and provides some physical facts to an issue that is very common (all temperatures in degrees Centigrade). The actual design operating temperature range is 86 to 73.9 degrees based on the thermostatic fluid regulator. For 4.2 liter engines, the automatic thermostatic (“otter”) switch immersed in the radiator top is set to engage the electric cooling fan(s) at 86 degrees and shut off at 74 degrees. Operating the engine at 70 degrees is not necessarily an advantage as the reduced temperature causes the aluminum pistons to contract twice as much as the cast iron block and steel rings, opening up the cylinder wall and ring clearances leading to cylinder pressure leakage and increased oil flow past the rings. (Note: the thermal expansion/contraction coefficient of aluminum is almost twice that of steel and cast iron). Ergo, if the standard system is operating properly, efforts to drive down the operating temperature such as supplemental fans are not necessarily a good option.
