    4.3 vortec engine ( water in oil )

    strip it down to a long block and swap everything from your running motor. some xpurt will say a camshaft swap is needed but with a truck motor the cam will be fine .

    4.3 vortec engine ( water in oil )

    nice thought , but defiantly not , the crack would go through to the head bolt threads.. the crack in the same area on my motor (as mentioned above) did this ,so i would assume the OPs motor block would have suffered the same fate.

    4.3 vortec engine ( water in oil )

    that is what happened to my second engine block, presure testing did not reveal any leaks ars it only became apparent when the motor was under load. i ran that motor 1/2 an hour on the hose / muffs , it did not even get a drop of condensation in the rocker covers, as soon as i took it over 4k...

    4.3 vortec engine ( water in oil )

    you may have a crack in the engine block or get lucky and its just a head or intake gasket. i recently went through a saga with the 4.3s where i had 2 cracked blocks , my first experience with the V6 was not pleasant coming from a V8 background . first block original to the boat had split bore...

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    it sounds like the oil pressure switch is stopping the motor from starting , however , can you try again with the " shift interrupt" switch disconnected (to rule that out) and report back.

    Condensation/water in oil?

    what motor ?. brown oil , sludge in rocker covers , sorry to say but i think you have a bigger problem than just some condensation. it is a possibility there is water getting into the oil somehow ( crack in block , cylinder head gasket ,intake corrosion ,etc) , you must find the cause ASAP or...

    196 351W Flywheel

    yes they are just slightly off, i usually mark the FW and crank with paint marker so as i can just put the FW strait on. but since you don't have that luxury :) ,a smear of grease on the end of the crank will make it easy to spin the FW to align the bolt holes correctly

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    i miss lake Eildon, it must be pretty busy up there since the Murray got floods. that said :) , do that compression test to address that rough running. the 5.0 is a robust motor but the head gaskets are a weak point when they get heated from lack of water flow. ? did any smoke come from the...

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    welcome from fellow Aussie , ( Perth ) , i would start by removing the outdrive , check the pump impeller and then for obstructions in the water passages / hoses to the motor. it sounds as if you may have overheated the motor ? is there any sign of water in the oil , if not a head gasket may...

    *( Yamaha WR650 crankshaft seal is bad can i move the engine forward and tilt it up to remove flange also how does the flange com off ?? any answers

    the flange / coupler is screwed on in the direction so as it tightens as the pump is loaded ( right tight , left loose), it usually needs a special tool to get them loose as they can be very tight , the ears snap easily if you force them too much. i have had to cut a few off over the years and...
