Hi all, I am installing AN Lines from my oil cooler to the block on my '75 GT4. I am getting rid of the banjo bolts that some have said are the bottleneck to the flow in the system and going with some curved 90 bends. There is a 26x1.5mm threaded adapter that converts our oil cooler to 12an size that was made for Porsche and subsequently fits our cars too! On my installation on the lower feed line, I found that with the adapter and then my 90 bend piece comes within about half an inch to the block or or more specifically the bell housing. I am sure that I can angle it to get more clearance. The oil cooler is fixed to the frame and doesn't move. The top fitting goes pretty close to the distributor cap. Sooner or later I plan on going electromotive and no disti's but for now I have this... My question to the experts, considering my engine mounts and upper torque bar bushing are in good condition, how much can I expect to see the engine move under load? Should I be concerned that the half inch clearance is not enough? I am sure the engine repeatedly hitting the fitting will bend/break and cause a leak - the entire reason I am going with this fix. I included a couple pics of the bottom fitting near the bell housing and the top fitting next to the distributor. Looking forward to the responses! Thank you in advance. When I am done i will post a full log of my fix and part numbers. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
The engine moves about a fair amount, I was a bit surprised when I noticed it. It moves more in reverse then the forward gears. In reverse the tilt is a good 1". The engine mounts are spring isolation dampers and have about 3/4" of travel in the vertical plane i.e. up/down. The engine will rock about under sudden load like drag launches or from a dead stop, esp in reverse under sudden acceleration. The top rod is best viewed as a pivot point.
