engine oil coler
I have a 2.8 with 46 IDA carbs and I have not run it for at least 5 years .I was going to send it out to be refreshed but decided not to.I removed the engine this week and have torn it down to bare block. I was able to prime the oil system and roll it over by hand so I don't have to worry about spun bearings . Next step is to replace a few hoses that have cracks in the oil lines and to check valve clearances and solid chain tensioners .I would like to find out if it is possible to remove engine oil cooler and replace it with a blanking plate . I have a huge oil cooler for the front of the car so it is really not needed . Also can I buy a partial gasket set for the engine or do I have to buy the whole kit....Thxs

Use a oil cooler block off plate from a 964. The one with the filter that goes where the oil cooler would be on a earlier engine. this will filter the oil thats under pressure to the main oil galley. you will also need to remove the thermostat and use a blank like the 935 used. It would be a good idea to use a thermostat inline to front cooler.

That's the perfect solution.I have a bypass adapter for the front cooler.I will post a pic of it later.I will also post a pic of the cooler and its capacity.

I didn't know that any 964's used the second filter on the pressure side. Thought that was only the 993.

Only the 993. My 1992 964 has the casting for the oil cooler, but the fitting castings were never machined and there is no filter on the engine.

I blocked my oil cooler because it was leaking. The easiest way was too turn 2 aluminum discs about the size of a penny and install them in the oil cooler inlet and outlet holes. The rubber gaskets seal against the discs. You then have to disable the thermostat. Easy way to do that is to remove the "guts" from the thermostat. The steel cap just pops off.

Oil cooler
Seems to me that this setup will not work for me as I have 3 connections on my oil cooler.
Two at the top and one at the bottom.

The opening at the bottom now becomes the oil inlet from the oil tank. You will still need an oil supply to the engine from the oil tank.

The low buck solution is to take a junk oil cooler, and cut off everything above the base plate. Then you weld on a plate at the top, and weld in an in and an out AN fitting. That allows you to run hoses to a remote filter. The two top oil holes in the case are too close together to just tap and use a fitting, so you have to use the plate on the cooler base to space them out. On the bottom, you weld on a bigger AN fitting for the oil to engine pump line from your remote reservoir.
If you don't want the filter (Porsche put one there on its race motors) it should be easy to use a junk cooler base plate to block off the top oil holes with slugs as mentioned, and tap the bottom for an AN fitting. More elegant is the 993 part mentioned. Fewer hoses and fittings, and you don't have to do anything special when pulling or reinstalling the engine. Sounds like the 964 part could be machined to take a filter, or certainly to take AN fittings for a remoter location. |

This is great info. Why the extra oil filter where the cooler is ?

The oil that is under pressure and going into the engine will then be filtered before it reaches the bearings. The stock system only filters the scavenged oil on the way back to the tank.

Here are some pictures swiped over time from Pelican posts.
This is a low buck approach to delete the engine oil cooler and not replace it.  Here is the 993 part. This is the more desirable version, because its angle allows you more choice of aftermarket filters - like the System One pleated screen reusable kind you see in the third picture.  Here is the 993 part installed, with filter, and a fabricated extension out to the pump inlet plumbing.  The (2) oil inlet fitting is either a stock part or an aftermarket part. Smartracing used to sell one. |

I'm liking the 993 setup . I will look into that setup as I to like the flexibility of the filter sizes. I will check out smart racing for inlet adapter.Nice clean setup ......thxs
