Re: Fairmont with PROBLEMS!!
Ok some possibilities include:
a) the inlet manifold has been put in back to front and upside down when the head was repaired so that the injectors a firing fuel onto the gasket rather than into the inlet through the cutout in the gasket. If so it would have played up immediately after the head was repaired and replaced.
b) If the engine overheated (perhaps when the head cracked) the alloy head has softened so the head bolts are moving into the head so it loosens at each end causing the gasket to leak again. These heads should always be checked for hardness when the gasket it replaced or any head work done. Read the bit on pages xi and xii in the ACL catalogue herehttp://www.acl.com.au/web/aclwebsite.nsf/8df7d3f7b605537a4a2569660082eda8/5c18db9339d686ed4a256967000e22ed/$FILE/45244170.pdf/AG05%20-%20Full%20version.pdf
c) The inlet gasket is leaking. Stick a metre or so of windscreen washer sized tubing in one ear and listen for the sound of sucking air when the engine is running under the inlet manifold at number 1 and number 6 cylinders (one closest to the front and one closest to the firewall). They bolts at these points can loosen if not correctly torqued and start leaking to the pint where the gasket is burnt out.
d) does it stall at low speed on turns? If so the power steerinf sensor (looks like a brake light switch on driver's side of steering rack) may have failed. This sensor tells the ECU to increase engine revs at low speed when the wheels are turning to compensate for the power used by the power steering system.
