New Thread I'm a slow learner...But like to learn...by hands on I guess..I had started a thread about maybe needing a head gasket, thought the problem was solved...PT must stand for "Pain N The...something"...lol. The car doesn't over heat, but air in the system keeps pushing a bit more coolant up into the overflow tank, not allowing it to drain back...even when the car has cooled down...the upper radiator hose still feels firm...when opened, no coolant in the upper radiator hose...but the hose had a lot of pressure in it, very firm. So I'm pretty sure, now after driving the car..."time will tell factor" its the head gasket...such a slow leak to...pressure tester indicated one...but pressure had been so gradual thought maybe a gauge thing. Did the new cap, bleed, flush, new coolant, power wash radiator, checked fan, everything works fine..fine on/off...stat opens...car had...flow to and back to the radiator in town, but now after putting some more miles on the car on the highway...100...no more flow back... WHAT IS THE BEST HEAD GASKET TO PUT ON...BRAND...UPDATED VERSION ~ MLS MULTI LAYERED STEEL are they the better ones...Felpro...all sorts of kits on eBay...which ones should I stay away from... The other question I have after doing some reading...all said and done...after install...Is a Tech Scan tool needed...to put the car in a learn mode for the crank position sensor...timing? Can you do this some other way...yes will have all the cam/crank pistons in the correct position/marks...Still need Scan tool? One more...do you really half to disconnect the AC lines to pull the head...can you just vent the stuff to the atmosphere? A lot of great threads here and on youtube...might get this project started the 26th..motor mount looks to be the biggest pain.
