2001 TB48 GU Patrol
Hey guys, whilst driving there is a whooshing noise when the turbo is at boost, wondering if this is normal or it could be a gasket problem, I have already had the intercooler off and all the pipes so all the pipes are in good condition and all tight. There may be a small leak in the intercooler but the sound is coming from the passenger side. So far from what I have searched it could be exhaust manifold gasket, turbo to dump pipe gasket or the manifold side of the egr pipe. Because it's only there whilst at boost (boost gauge fitted) it seems it may be turbo to exhaust gasket but I'm not sure welcome to any helpfull suggestions, thanks in advance Jay.
