Nathaniswhite Posted January 16, 2013 Share Posted January 16, 2013 Hey every one, I have 2006 spec b and im driving in the snow a lot. I just replaced the air filter because it was filthy from all the salt on the roads but I was also wondering about my intercooler. Does that need to be cleaned because I have a feeling that it is dirtier than the air filter. What my question is, does the intercooler need to be cleaned and if so, what is the bes method also a side note, how do you know if the turbo is going out? any sounds because I heard a whining sound after my 4 hour drive today.

BoozeRS05 Posted January 16, 2013 Share Posted January 16, 2013 Intercooler- if its not covered with rocks and bugs its fine. You could remove it and shake it upside-down, maybe take a vacuum attachment to it gently if you want to be weird. Pick the rocks/debris out and keep the fins straight and it will be fine. Turbo will whine, burn oil, and ultimately screech or sound like there's rocks tumbling around in it before/when it goes. If you pull the inlet tube off or the downpipe off you can feel the compressor wheels and check them for movement. Movement is bad, mmkay.

Gex Posted January 17, 2013 Share Posted January 17, 2013 If you have an air compressor with a chuck just take it off and blow it clean. Link to comment Share on other sites More sharing options...
Max Capacity Posted January 17, 2013 Share Posted January 17, 2013 You need to address the whining turbo before it goes and takes out the engine. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

wurkenman Posted January 17, 2013 Share Posted January 17, 2013 If you have an air compressor with a chuck just take it off and blow it clean. Just not too close or high pressure or you will bend the fins over. If you woke up today, you have another chance to do it right. Link to comment Share on other sites More sharing options...

Nathaniswhite Posted January 17, 2013 Author Share Posted January 17, 2013 the whining went away it was just that one time and it never did it again. do you think it was just because i was driving for four hours straight? Link to comment Share on other sites More sharing options...
robitrice Posted January 17, 2013 Share Posted January 17, 2013 should not whine at all. the only other thing could be a boost leak, but you would only hear the whine if you got into boost hard. Check the Turbo to Intercooler flange and the throttle body connections to make sure no leaks. Link to comment Share on other sites More sharing options...
babybluelgt Posted January 17, 2013 Share Posted January 17, 2013 Get that turbo checked out!! There's plenty of people on here, myself included, that can tell you a blown turbo is a lot more costly than just bolting a new one in. Hopefully you can save it before it damages your engine too bad. Link to comment Share on other sites More sharing options...
lgt_nube Posted January 17, 2013 Share Posted January 17, 2013 Is that because a blown turbo would damage other parts of the engine? a blown turbo is a lot more costly than just bolting a new one in.

BoozeRS05 Posted January 17, 2013 Share Posted January 17, 2013 When a turbo goes it can go badly, and leave metal in your oil to circulate in your motor. Lots of people replace a blown turbo and another turbo goes shortly after because the metal is still there, then the motor goes shortly after that, it can add up. Definitely good to practice preventive maintenance and be diligent in checking your turbo if you suspect an issue.

BoozeRS05 Posted January 17, 2013 Share Posted January 17, 2013 Periodically check the banjo bolt, shaft play and boost levels. Monitor noises/whining and oil usage for moderate and dramatic increases.

robitrice Posted January 18, 2013 Share Posted January 18, 2013 consistant oil changes, generally if you change your oil at a good OCI (Oil Change Interval) you will be good. Link to comment Share on other sites More sharing options...
lgt_nube Posted January 18, 2013 Share Posted January 18, 2013 That's what LIC Motorsports (Novato, California, that services my car) says. They say they can almost always trace trouble with a turbo to missed oil changes or running low on oil. I'm going there today for my OC at a 3,750-mile interval on this almost-150,000-mile LGT :-) consistant oil changes, generally if you change your oil at a good OCI (Oil Change Interval) you will be good.

BoozeRS05 Posted January 18, 2013 Share Posted January 18, 2013 They say they can almost always trace trouble with a turbo to missed oil changes or running low on oil. I absolutely agree. Check your oil often, and top off even if you're adding less then half a quart. If you are at all concerned pull the banjo bolt and/or check for shaft play. At 150k miles I'd definitly have them do one or both if you're in the dark on these items or the car history.
