mademan Posted January 29, 2009 Report Share Posted January 29, 2009 I took a 94 fleetwood brougham for a test drive yesterday, its in GREAT shape, interior is mint, body is great, all original o damage. Chrome is excellent. But the motor has 298,000 KILOMETERS (canadian) and the first thing I noticed is that the Coolant reserviour and Rad are full of oil. The car runs smooth, drives great, doesnt burn any oil, doesnt smoke, or leak...... Im wondering if the Elderly man that traded it in may have just accidentally filled the reserviour with oil??? or is it mabey the head gasket, or cracked block? for the price im really not too concerned with it, as it will be a long term project (as with my 64 deville convertible 429 buckets/console car) I have an air suspension set up and everything already. I have a 1994 roadmaster wagon with the lt-1 with 130Km on it lined up for $200.00. Im thinkin I may just do an engine swap as it is 1/2 the KM on it. my only question really is.... Head gasket?... or? sorry for the long readd, any help is much appretiated! and a pic of my 64,.... just `cause thanks, Mike Link to comment Share on other sites More sharing options...
Ranger Posted January 29, 2009 Report Share Posted January 29, 2009 My guess would be the oil cooler in the radiator side tank is leaking. Oil pressure being higher than cooling system pressure will put oil in the cooling system. However, when it gets shut down, cooling system will still be under pressure and oil pressure will be zero so now coolant will mix with the oil. If it where a head gasket you might see coolant in the oil, but not vice versa. Link to comment Share on other sites More sharing options...

KHE Posted January 29, 2009 Report Share Posted January 29, 2009 Ranger's advice is right on. Check the oil cooler line in the radiator side tank for leaks. Head gasket failures in the LT1 engine are extremely rare. I wouldn't swap engines until when or if anything happens to the Cadillac engine. That's just my opinion though.

95SevilleSLS Posted February 3, 2009 Report Share Posted February 3, 2009 I've seen a lot of Cadillacs and to have a stock sunroof in the older ones is pretty rare. I've never seen one in a fleetwood. -Dusty- - 02 Seville STS, white diamond - 93 Sixty Special, Tan with vinyl top - 79 Coupe DeVille, Tan with Tan top - 06 GMC Sierra Z71, Black - 92 Silverado C1500, black and grey - 83 Chevy K10 Silverado, Black and Grey Link to comment Share on other sites More sharing options...
