1972 Porsche 911 engine

A 70,000 mile 1972 Porsche 911T came into our shop after sitting for man yyears in a barn. The brakes were sticking, shocks were bound up and the engine had numerous oil leaks and was pushing smoke out of the tail pipe.

We decided to repair all of the items to make the car safe to drive. We replaced all of the shocks, re-built the brakes, re-finished the wheels and addressed a number of other items. The car went down the road like a champ, but the smoke and oil leaks hindered going further. Also, the knocking noise in the timing chest were too bad to ignore.

We decided to break down the engine, perform a valve job and install new piston rings. We are not going to split the case but we will replace all of the seals and gaskets. One thing that was a issue was the original chain tensioning units collapsed which would be catastrophic had we driven the car more.

Needless to say, we are going to replace the tensioners with the updated oil pressure charged units. Have a look at the slack in the timing chain on the LH bank!
