hi all, i am in desperate need for help.

i have a 89 escort, which has a rs 1.6T engine replaced form a 1.3.

when i bought the car it had a slight oil leak, from the sump gasket. i drove it home, as i got home the ticking from lack of oil got louder. i ended up pushing the car beacsue i was scared to drive with such low oil. but i think i may have just drivin it to far!

i changed the gasket, and 2.5liters of oil came out, which made me think there must have been enough for the engine to run, as the 1.6Ts need 3.5 litres aparentlly.

so once changed, i started up the car, (which had to be jump started as i have a completly dead battery now) and all sounded well, the ticking dissapeared as the oil set through the engine.

however, as i reved it up to about 3000, a ticking/knocking sound came from the engine, i have been told this could be explosions in the engine from bad timing???

i revved it a little higher and the car backfired quite loudly, the engine dipped in revs majorly, and i heard a whistle sound from the engine. kinda sounded like the dump valve, but im sure it wasnt. i did it again, and the radiator blew, a small hole appeared and spray of coolant came out. (i dont think the radiator has been upgraded to a 1.6T from the 1.3, if thers any differance).

as i revved it btw, the battery light came brighter and brighter. so i know i need a new battery, the question i really need to know is what is making those explosions/knockings.

could it be the timing? sparks? lack of coolant and right radiator, just a dead battery which is not providing the right current to the ignition?? i really dont know!

any help would be MOST aprecialted, i really dont want to spend pointlless money if the eingine has blown or something :S

thanks in advance! HAv.
