Hans, Your engine number indicates that it was a 130 HP (911 as opposes to a 911S) which is also known as a Normal engine that became the 911E with the addition of Bosch mechanical fuel injection the following year. The 911T engines, for which I do not have engine numbers in 1968, used cast aluminum pistons and cast iron cylinders as opposed to forged aluminum pistons and biral cylinders in the 130 HP engine, a milder cam profile and smaller venturies with different jetting in their Weber carburetors. The only 2 liter 911T engines that I am familiar with have engine numbers starting with 619 but i believe that the second digit indicates 911T=1, 911=2 and 911S+3. The third digit indicated the model year so if your engine number started with 618 that would denote a 1968 911T. This is only an educated guess backed by many years of experience with 356, 912 and early 911s. I hope this helps. Some trivia that you might be interested in indicates that the original 901 (911 and 911S and 911T) engine crank cases were made of aluminum. Starting near the end of the 1968 production year they switched to cases made of magnesium because the magnesium was easier to machine and cast although not as strong as the aluminum. In 1978 they went back to aluminum cases because by that time the displacement had increased from 2 liters to 3 liters and the magnesium was not strong enough the handle the increase in torque and horsepower. You can tell the material from which your case is cast by counting the exhaust valve cover studs and nuts. 6 indicates aluminum and 11 were used on the magnesium engines. Joe Reid

I hear many opinions but no documentation. You might want to read the following article from Mechinery Lubrication magazine. It explains why organic acids have replaced glycols and how they both work. http://www.machinerylubrication.com/articl...p?articleid=841 It is the best explaination I have seen yet.

Pete, Did you find how to add cruise control to your MY98? I also have a 2.5 liter and would like to retrofit cruise too. I would appreciate you sharing any info that you have found toward that end. Thanks. Joe

I recently bought a '99 with <9000 miles. It has never been back to the dealer or had any other service. I just changed the oil and filter for the first time and had it analyzed, copper was high but all other elements were at or below normal range. (not on topic but just thought you might be interested) I want to change the brake and clutch fluid. My question is: what is a Motive? Is it some brand of pressure bleeder? I don't have one and was planning to make one but if one is available commercially I can justifiy the expense related to the time it will probably save. Thanks. Joe

I want to buy an original, ugly, orange right rear light assembly from anyone who is upgrading. Email or call 908-766-7174. Thanks Joe
