I recently replaced the engine in my k11 after mine seized...engine I replaced it was an automatic engine there exactly the same...but when I start up my engine I can hear like a tapping noise from it dunno if it's the pullies or something inside the engine..I also need to replace the spark...
my last engine seized due to flood water
so i replaced the engine with a 99 automatic engine everything was the same on my 98 engine
i got the new engine and clutch in
fired up the engine and started
itll only start if i give it full throttle and let go off the key
but check engine...
