Re: noisy valvetrain
Thanks all for suggestions, I changed the oil and still the same.
I took off the rocker covers, got the engine hot, shut it down and pressed on the rockers with my thumb, number 5 intake lifter I can compress fully with my thumb, I started it up again and put my stethoscope in all the polylocks , it is the noisier that the others.
is this a "collapsed " lifter? can it be fixed or must it be changed, it has zero miles on it so cannot be worn out, I have seen a lot of similar issues with Compcams roller lifters on the internet, starting to wish I got standard hydraulic lifters now. anyone managed to fix one of these?
