ADD Posted April 1, 2008 Share Posted April 1, 2008 I have a horrible blown exhaust sound coming from under the turbo shield, when i try to boot it slightly the boost increases but the car doesn't react. I Put my foot once this morning at it hit 1.2bar but very slowly accelarated! could this be a major problem? or is it likely to be the symptoms of maybe a cracked manifold? Any help would be much appreciated! ADD Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 1, 2008 Share Posted April 1, 2008 Sure sounds like a blown turbo wastegate housing gasket, or turbo to manifold O ring. As they are very expensive from Toyota some people try and re use the old ones, which can cause trouble... Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted April 1, 2008 Share Posted April 1, 2008 This is probably going to tempt fate, with regards to the expensive "O" ring manifold gaskets, i found a cheap solution at my local parts place, an exhaust gasket, they work out at under £2 each ( i will try and hunt down the part no for anyone interested, mine have been in for a year now, and i did carefully check them out, took them apart to check construction, i also checked out how they crush against the Toyota one.

This would cause a lack of performance i gather? since ive had the hybrids on, it has always made a 'boost leak' noise under on full boost. Thanks chris.
