Need opinions HG v. "new" engine

My car won't start, oil looks milkshake like, but car doesn't overheat when I drive it. A mechanic that I took it to thinks that the previous owner overheated it and blew the HG, he estimated me the cost and labor for a "new" engine. I'm trying to find the least expensive route and still keep my car. Should I fix the HG and whatnot or just replace the engine? Any help would be much appreciated cos the estimated cost to replace the engine is 2000 for engine plus tax then labor I'm looking at almost 4 grand. I've got someone looking at it now over the weekend while the mechanics shop is closed and he's been a mechanic for over 15 years. He's going to run some tests on it and his labor cost is a lot less than the ASE certified mechanics. The car is an 01' 530i with 89k on it. Thanks have a nice day

Oil and coolant mixed usually points to one (or more) of the following:

Bad head gasket

Cracked head

Cracked block

All of the above were usually preceeded by at least one episode of overheating, with the more severe damage caused by someone who continued to drive with the car in an overheat situation.

A compression/leakdown test will help diagnose the actual problem. Good luck !

If you put 4 grand into the car--you will still have a car that is worth exactly the same amount
as it was the day before the HG blew. Not worth putting 4k into a 7-8 k car. Plus-I assume the
new engine is "new to you" as in used. Could last a 100,000 miles or could last 1000 miles.

If you put 4 into it --then you are committed to putting X more when something else goes out.

Used cars force some hard decisions.

I agree. Which is why I am using that as a last resort. And yea the "new" engine is a used engine, it has 94k on it where mine has 89 and it comes with a 6 month warranty. I have an extended 5 year warranty: ***65532;***65532;ENGINE and WATER PUMP - All internally lubricated parts of engine, including pistons, piston rings, piston pins, crankshaft and main bearings, connecting rods and rod bearings, camshaft and camshaft bearings, timing chain and timing gears, intake and exhaust valves, valve springs, oil pump, push rods, rocker arms, hydraulic lifters, rocker arm shafts and water pump. The Engine Block and Cylinder Heads are not covered unless damaged by an above listed internally lubricated covered part.

But that doesn't help me in this case or I would just have the warranty cover it.
