Had Dans firebird in for a few problems diff pinion seal leaking, transmission tail shaft seal leaking, N/S halfshaft seal leaking, both valve cover gaskets leaking, and the exhaust header leaking and blowing by quiet bad. Got the propshaft removed and removed the tail shaft seal and replaced then stripped and removed the pinion fl**ge cleaned up around diff and removed old seal got the new seal fitted and reassembled the fl**ge and fitted prop back in place, removed diff cover and drained oil then stripped diff partially so we could pull the halfshaft , got that pulled out and replaced that seal then polished the shaft so it runs smoothly in the seal then reassembled the diff and filled with new oil with L*D modifier. Then moved onto the header where we found the middle bolts one was missing and one wasn’t put in properly as it was a metric bolt and had damaged the threads so removed the oil filter housing and raised the engine to allow the header to come down after disconnecting the exhaust, cleaned up the mating face and run a tap up the threads to repair them then fitted new gasket and put manifold back in place fitted oil filter housing with new gasket after cleaning all the mating faces up, dropped engine back in mounts and bolted back up then stripped the aircon compressor out and all it’s mounting brackets for access to remove the right bank valve cover had a few issues with seized bolts but got them all free without any breaking then removed valve covers and cleaned up both sides fitted new gaskets with a little RTV sealant and fitted back in place, refitted the aircon bits and topped up engine oil started engine and found it was still blowing somewhere which turned out to be on the other bank because the rear bolt hadn’t been fitted so got a new bolt fitted and that sorted that out then took for a road test and placed back on ramp to check for leaks all good and back with Dan now
