Sand all over on flush .... Buy coolant filter
Well, I just did my egr delete and put a new oil cooler in last night. I did the first flush with simple green and ran it for an hour. I then drained at the radiator through the pet****. There was not a lot of sand or oil coming from the radiator so I continued with my drain. Next I pulled the plugs off the block and drained into a clean bucket. I was amazed at how much sand came out of the block. I would say there was at least 4 tablespoons of sand from what I had caught. I cant believe there was that much in the system. I will be flushing with VC-9 next along with several straight water flushes to clean out everything that I possibly can. After that I will be putting a coolant filtration system on. The only problem I have left to deal with is the intercooler hoses that keep blowing off because I got oil on them. I just figured I would share my findings with everyone on the board.
