![]() While in there, as a second major project decided to completely remove the intake manifold for proper cleaning (throttle body was really dirty), bought new gaskets for both the intake manifold, dynamic chamber, EGR valve upgrade kit (brings EGR into the coolant loop with throttle body) - comes with new hoses, EGR and throttle body gaskets, new intake side o-rings for the fuel injectors (really, the new ones don't seem any better than the old ones!). The good news is that I'm getting very good at the timing and belt install. All valve seals re-replaced (one on #2 cylinder seemed loose - didn't find any obvious damage to any of the seals). I replaced the oil seal even more carefully, this time very lightly coating the outside edge with red high-temp pematex. Since I didn't know if I had damaged a seal, or if one was simply installed incorrectly, I didn't want to chance taking the engine apart a third time so I chalked it up to the learning experience and bit the bullet ($160 x 2). AND my crankshaft oil seal (which was not previously leaking, and despite careful removal/replacement) started LEAKING!Īfter many more hours of online research and reading the service information, I decided to do the valve stem seal job completely over, with a better (really awesome) spring compressor tool and with a completely NEW set of seals just to be safe. Only happened after resting overnight, no smoke in cruise. Sadly, startup smoke got WORSE! Still blue - about 15 seconds after start up, fog the block for about 1 minute then gone. YAY! and timing felt great - no more marbles. All parts from Mazda except fluids/plugs.Īfter much trial/error and a few new tools, I finally got all the work done and the car back together. While in there, I changed my crankshaft (front) oil seal, camshaft seals, valve-stem seals (hoping this would cure blue startup smoke issue, oil consumption), water pump and gasket, thermostat, valve cover grommets/bushings/gasket, timing belt, alternator & power steering belts, oil change (synthetic) with filter, coolant flush/change (pet-friendly coolant), spark plugs. Car has approximately 230,000 km (~142,915 mi) and the belt was original. resolving one set of problems leads to worse.ģ weeks ago, after many hours of online research and reading (have the Mazda Service information) I tore into my engine to replace the timing belt for the first time (myself and the car).
