  • screeching noise!!!!

    Hi there, i've just fitted a new head to my '94' 3.0 td surf. It fired up easy, sounded right on! Untill i started to build up the revs a bit, then at around 2500 revs there was this strange screeching sound, as soon as i let off the gas it went! Also when switching off it gave a loud screech. I've taken the air con belt off and checked the tension of the other belts and it's still doing it!! Any advice would be greatly appreciated. Cheers, Dave.

    have any of the wheels the belts go round got any play in them cause on my 94 3.0 i think its a bearing on the little wheel next to the air con that has some play in it but check the other wheels to see if there is any play.
    i hope you understand this

              I'm a bit of a 50's lover myself. Mind you the 60's and 70's American cars we're great too. I've got a '54 chevy truck' at the moment and it's a pleasure to work on compared to modern vehicles. I won't let Claire read this mind as i'm always glad to borrow her 'modern vehicle' in $$$$py weather though!!!

                  I know the one you mean in Hayle, it's a purple one, i think it belong's to a chap called Pete. Mine's usually in the St.Erth area and is satin black! I don't know the other guy with the 96 3rd gen.

                            There have been a few of us with the same problem. Mine still does it since head replacment. Could be a belt but almost the same sound appears to come from the turbo when failing (bearing wear causing blades to hit the sides) or an air leak around the same area.
                            One guy said the inlet manifold gaskets didn't seal properly and a bit of instant gasket did the trick.
                            I'm sure mine is the turbo but I do have a small blowby on the exhaust manifold which may be causing the multi layers steel gaskets to whistle.
                            Smack it with a 16lb Hammer and it will come off!

                              all sorted!!!!!!!!!

                              Hi there,
                              Sorry for the delay in posting this! Thanks to you all for your advice. I decided i would take the inlet manifold off and reseal it with some instant gasket (as this wouldn't cost me anything)! Before i got to far into the job i discovered the unit on the back of the inlet with the link pipe that goes across to the exhaust manifold was loose... i caught the nuts, but forgot to tighten them (fool)!!!!!!! So i tightened them in put the other bits back on and hey presto.. noise gone!
                              Thanks again, Dave.
