When it rains it pours - engine oil leak under blower

[tomolmsted]

I've got a very fast engine oil leak coming from under the blower housing where I cannot see. Any ideas? Can the blower housing be removed without dropping the engine?

Thanks,

Sounds like the oil cooler seals, you will need to remove the engine to remove the blower housing.Then remove the oil cooler and replace the seals. I don,t want to worry you but I had the same problem on my car and I finally traced the fault to a crack in the crank case around the base of the oil cooler mounting flange.

I had the same problem; cracked block at the oil cooler tower stand; thought it was the seals, replaced them, reinstalled the engine and still leaked; the only way to fix is a new block or an expertly ground out and welded up block, full rebuild either way

You need to lower the engine remove the shroud and run for a min or two(engine will heat up fast with no dog house on it so 1-2 min is all you want to run) check for oil coming out at the base of the tower; this area is prone to stress cracking and unfortunately the main bearing supply galley runs right under this area on its way to the cooler!

good luck

I was able to lower the engine a tad, remove blower housing and restart it. Oil came from middle of cooler where it was rusted. Will get new cooler from Harry Pellow. Thanks for everybody's suggestions.
