robby Member 15 Member For: 13y 9m 10d Posted 03/08/10 06:42 AM Share Posted 03/08/10 06:42 AM Hey guys dont know if anyone else has found this on there BA turbos but I thought id let you know what happened with mine. After cleaning out throttle body (rough idle problem) I started the car and noticed engine lift bracket on the inlet manifold side moving I stopped the engine and checked the bolts in the inlet manifold and found all of htem to be very loose you can get to all the bolts if you remove the cross over pipe and get the others from under the car.Might be worth a check guys and idle is perfect now Link to comment Share on other sites More sharing options...

Rosie Member 361 Member For: 17y 12d Posted 03/08/10 12:23 PM Share Posted 03/08/10 12:23 PM Got a 'fix' for the Bolts holding the Manifold onto the Block!- Ford fits the Bolts through the Heat Shield and Manifold, then into the Block!- The constant hot/cold of the Manifold causes the Heat Shield to shrink and the Nuts get loose!Found a good old fashioned Engineer who simply replaced the Studs with longer ones.- He then bolted the Manifold 'directly' to the Block, fitted the Heat Shield over the longer Bolts and then fitted separate Nuts over the Heat Shield to hold it in place!As for the Bolts to the rear of the Turbo, they have the same hot/cold problem!- The Ford Nuts are Copper jacketed and when they to work loose, they are basically shagged!- I replace them with new ones and I get 'marginally' better wear before they come loose again.At the end of the Day, it's just another 'pain in the Ass' ongoing maintenance issue!But at least we fixed 'part' of it!
