Oil Dip stick level accuracy on a 993 conversion on 1975 911
 

Hello, I am new to forums, but I will start by asking a question.


I recently acquired a 1975 Porsche 911 with a 1995 993 engine swap/conversion, with the stock 915 transmission. If anyone would know the answer to my following question, it would greatly be appreciated.

My goal is to read the accurate measurement of the oil level. My oil level indicator in not operating , and the car currently has the stock OIL DIP STICK from the 1975 engine. When I check the oil on the original dipstick (the short dipstick , compared to the long 1995 993 engine dipstick), it is half way. However, I just wanted to make sure if this reading is reliable, due to the fact that my engine is now a 3.6 L compared to the original 2.7 L engine it had before. Does any one have any thoughts on this?

Don,t want to be running the car with less than the required level of oil. Thanks!

Your plumming and hoses are for the rear tank of the 75. That dipstick for that tank is the only one to be concerned with.
You want warm oil on level ground at idle to read the dipstick. The longer dipdtick of the 993 is for the tank back by ther cars lockpost, nothing to do with the 75 tank.

+1 on what Bruce said.

Don't get hung up on the oil lever meter, its mostly confusing anyway, especially for someone who isn't acquainted with the 911.
Make it a routine to check oil level on the dip stick at regular intervals, keep oil level in the middle between min and max.
