Symptoms: 1. Fuel gauge that would randomly read different values, so you never knew how much gas was in the tank 2. Hesitation would appear after filling the car with gas. 3. Fuel smell 4. Lot of pressure released when opening the gas cap. Last fall we had torn into the fuel system due to a hesitation it was having after filling up with gas. Aaron had also noticed that the tank let off a lot of pressure when opening …

Aaron brought by his 968 last night to have me go through the speedometer cluster. The 944/968/911’s are notorious for the plastic odometer gears breaking, and thus the miles stop accumulating as you drive 😉 Aaron of course brought this in immediately when it broke 🙂 How do they break? Well over time, the plastic can get brittle and just flat fall apart, but the #1 cause is from people hitting the odometer/trip reset button while the car is moving. …

Aaron dropped off his 968 the other day because it died on him and wouldn’t start on his way to work.  He had been having some wierd hesitation issues as well, so it was time to take a look at it.  Found the bad fuel pump right away, and started tearing things apart.  Since we are in there, we replaced the pump, tank screen, fuel filter, check valve, and the fuel pressure regulator.  Once inside, we found the reason for …

Another 968 in the garage.  I am doing a full timing belt/waterpump/roller service, swapping in a resealed PS pump, Camshaft pads and chain change, all new coolant hoses, new expansion tank, speed sensor, and trying to figure out a braking issue. Getting ready to tear it down….. Front end apart, going after the cam pads and chain….. Cams out of the car….. Exposed cam followers. Old pads and chain that need to be removed New pads and chain installed, and …

Another 968 came through today.  158k miles on the clock, with an unknown history of cam maintenance. Pulled the valve cover to see what we were dealing with.  The top pad, while worn, was not in horrible shape.  Typically I see more wear on the bottom pad, but you can’t inspect it without pulling the cams and tensioner. Cams out of the car……To pull the cams, you need to remove the timing belt.  On the 968, that more or less …

One of the biggest problems you might face in a race car in the summer heat is over heating.  I’m not talking over heating of the car, but instead overheating of the driver.  In the summer months when temperatures can get to 100 degrees, finding yourself in a metal box with no AC for 20 minutes to an hour at a time, means being stuck in a heat sink with no way to cool down.   Over heating the body leads …

Knocked out a corner balance on a track prepped 997S today.  The car was set up pretty good last year, but this year the owner decided to pull the supercharger off, and remove the A/C to make a lighter car, which of course messed up our weight distributions on the car.  Scales showed the car came in just under 3050lbs. What is the purpose of corner balancing? Corner balancing is the process of shifting the weight carried by each wheel …

The Porsche 968, 944S2 and 944 S all used dual overhead cams, unlike the previous 8v engines.  This also introduces a slightly different maintenance schedule for the cam system.  The 8v engines were all more or less cam maintenance free, with the exception of oil seal replacements as they started to leak.  The DOHC heads though, all have tensioners, oil feed pipes, cam chains, and tensioner pads to worry about.  The 944 line is fairly basic in terms of maintenance.  …
