I have just finished changing the coolant in my 850T (1994). When I tried to refill the coolant, I cranked the car but the engine sounded like one that did not have any muffler attached - really obnoxiously loud.

My mechanic has checked the timing & serpentine belts and everything seems to be OK. I cannot imagine that changing the coolant can cause problems like this. This should be a straight forward piece of maintenance.

Caan anyone shed light on this problem?? My 850 & I have been separated for a week now. We would like to get back together and keep this relationship alive.

Thanks!!

Well, it's been an interesting week. So far, I have had the cyinder head gasket replaced along with all the associated checks and parts replacement that go with it. However, the coolant is now still leaking into the oil.

When I started the car for the first time today the engine sounded relatively good but there seemed to be a knocking or pinging noise. But as the car ran it seemed to quiet a little.

The oil has been flushed/changed twice now but with no change in the mixing problem. The Check Engine Light that had been on is now out and the mechanic is pulling no codes for the car.

Is there something that needs to be done further or has the mechanic forgotten to do something in addition so that the problem will be corrected ?? Also can I drive the car home (approx 10 miles) without damaging the engine ??

If anyone can reply with an answer it would greatly be appreciated. The mechanic thinks that the car will not last much longer but this is not my experience with these great cars. I hope that I have not turned my engine into an expensive boat anchor.
