964, NOT just another engine build with oil leaks
Its a great deal more removing the engine especially if I don't do 964 everyday. The engine was diagnosed with case bolts leaking. The rubber hose on the bottom of the tank was marking its spot as was the panel under the engine. Its amazing how clean the engine is with the panel removed. 150K and the oil tubes are still shiny.
The fun Saturday was taking it out of the car and today is looking at the cleanup needed just to work on the engine. Bruce

Bottom pics looks like alot more than case through bolts. PCV cover/OPRV cover/oil pressure sending unit leaking at all???
Your car? I love the 964's, my favorite of the aircooled street Porsches. I will own or build a 3.8RS rep at some point in my life

Well, I havent got the 3.6 all opened yet, still have to get the exhaust and the cat out of the way. All I can say is, It ain't a 3.2., there is more hoses and wires running everywhere and then there is bags of insulation between the engine and the exhaust. My younger brother always says, if there is oil in them, there is oil on them.

I'll be interested to hear how you deal with the flaking coating on the insides of the valve covers... it can't be good for your motor, having that stuff floating around in the oil.

Well, no head gaskets so the factory updates were never done at the time.
There is 24 dilivars in place too, got to swap them out too. Bruce

Wow, I have never seen so much blow by with all of the head studs still intact, were the head gaskets a cure for some of that?
Woo Wee that is one dirty little mutha. Oh, and thanks for taking us on another ride Bruce! Looking forward to this one

I split the bottom end today, it sure needs cleaning. The inside was choice as expected, original bearings in excellent condition. The intermediates are shot as usual, showing brass.

I'm really looking forward to following this rebuild. I have never seen so much oil on a motor...
Will it be a "stock" build, or are you looking for performance updates too? |

Well, I pulled the mains and marked them all for location. First a cleaning in the
Safety Kleen and then some outside time with the pressure washer. Back on the engine stand and removing the 24 dilivars. Next step is putting the crank and oil pump back in and resealing the bottom. Bruce

Great work here Bruce...let me ask you something...if you are retired & working at a retired persons pace I presume, how the heck do you pump out work like this & so fast...?? I read earlier that you worked for a shop or dealer or such for 30+ yrs, but man oh man do you do nice work & at a fast clip...!!
Keep up the great work & sharing what is encountered as this is great to watch... Bob

Took a couple days off with the family and I m back home on Sunday at 2:30. 5 hours on the road from the mountains to home, I need to unwind.
Off to the garage and put the halves together..Tomorrow torque the cross bolts which already have some pressure on them. Bruce
