Main Oil Cooler Replacement


Skip

Recommended Posts

I'm trying to remove the main oil cooler on the right side of the crankcase to replace the seals as there is a leak at the base where it enters the crankcase (opposite the S-tube from oil tank. I can access the bottom bolts without removing the heat exchanger and I think I can get to the upper ones by removing the air intake box. My question is, can the oil cooler be removed without (a) lowering the engine - as recommended in Bentley Manual; and (B) taking off the heat exhanger?

Any help would be appreciated.

Thanks

I have to disagree with porschetechnik, there is an old bulletin on putting some sealant on the case and you had to remove the cooler to get to it

I did all of them with out dropping the motor.

there is a cowling on the top of the cooler that lets you get to the top bolts

Thanks to both for the replies. The joy of oil all over the engine from years of minor leaks makes it somewhat difficult to figure out, but slow and surely I'll give it a try.

Over the years I have done it both ways. I you are youg and bend well it can be done in the car. I you are not that bendable and you want to really clean the engine, pull it.

A 912 is not that big a deal to pull. Over the years I have probably pulled 20-25 of the little devils. Those and 356s. Never a 911, I didn't want to get into all of the

specialized tools required for the 911.

I guess I'm not that bendy would be the answer. I did drop the engine in the end - not too difficult considering it was the first time. Did buy a special bracket from Pelican designed to fit on a 3 ton jack and perfectly balance the 911 engine and transmission on the case (with padding). Didn't really need special tools less the metric wrenches and so on (which I do have). I managed to get to the cooler cover and the cooler and simultaneously took off the skirt parts to clean it up - cauusing further parts purchases with what I found, but well worth dropping the engine to replace seals and so on + clutch and flywheel which slips terribly.
