Been banging away at the cars in my spare time. Our 968 braking issue turned out to indeed be front warped rotors even though they only had 2000 miles on them.  Lesson learned here is that when common sense and experience tell you something is broken, don’t look past it just because that item has been replaced recently……new parts fail, rebuilt parts fail, new rotors warp, stuff happens.  The calipers had been rebuilt recently thinking it was an issue with …

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.

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 …

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.  …
