I have a 97 suburban 2500 with the 350 Vortec I have gone through three engines personally and every time they go there are metal flakes in the engine oil cooler and the radiator is leaking antifreeze. It makes a rattling sound like something is loose I cannot identify what it is but it has happened on three engines all three with less than 200,000 miles on them.

 

Welcome to the Chevy Forum. Not sure what your question is for us.
So this is your 3rd engine in your 97? How many miles on each one? Did you buy this vehicle new?

 

No i didnt buy new the last engine had 142000 on it i may have put seven thousand on it this is the third time the engine blew with me everytime just before it blew up the radiator would start leaking out by where the engine oil cooler is connected im just looking to see if anyone has had the same problem and if maybe the antifreeze leaked into the oil and washed out the bearings or something

 

No I didn't buy vehicle and brand-new I bought it two years ago replace the engine drove it for about a year and had to replace engine again and then again now

 

did you replace the oil cooler, radiator and flush the lines when you replaced the engine?

 

Yes i did with new cooling lines and a new radiator
