Rod Knock??? Why!!!!

wyosupra · 09-18-2007, 01:32 PM

Yesturday I finally Finished my HG

, and now it sounds like I have a slight rod knock only at about 2000 rpm, but I dont think it was there before, it runs fine and isnt getting any worse, it might have gone away.
ANY SUGGESTIONS??Or why now???

The coolant got down into the bearings from your Blown HG and that has caused your rod knock. You most likely did not drop the oil pan to take a look to make sure though did you?

The oil wasnt a milky color, it ran fine when I pulled the head. Compression was gettung into the cooling system. No I didnt pull the oil pan. Should I???

No need now. The damage is irreversible.

The cam caps looked like the engine was oil starved at one time. Now that I have some miles on it, the knock is gone

I just barely bought it, it now has new HG and a 2.5" turbo back exhaust with 1 cat. and a cone filter. Im planning on running 13 pounds of boost, I wont hit fuel cut at this high of elevation just under 7,000 ft. Any guesses if I can learn to launch?? Im getting the OBX downpipe and 3" straight next week.
