Timing problems

Post by **ZwhiteshadowZ** » Sun Mar 14, 2004 3:00 pm

I just bought a 240sx that has been sittin for acouple years... when i first got the intake manifold gasket was bad so i replaced and it ran fine.. i took it for a test run and got it up to about 7g and a knock started and it started running on 2 cylinders with a horrible shake when it idles... so i took off vavle cover and adjusted the timing chain but cylinders 2,4 still have low compression any ideas?

you probably bent valves if you had to adjust the timing chain.

check the valve spring. it might be the couse of bent valve.
