if its from teh block then probaly rod bearing with play in it or something internally thats not good....

head wise could be valve adjustment.

either way i wouldnt go high rpm until you find out or fix it

- Mon Jan 25, 2010 3:10 am #170857 if the valve cover says vtec-e and has small intake pipes, if the valve cover says vtec and has bigger intake pipes then its a VTEC version similar to the d16z6

If the intake manifold looks like the above, Its VTEC, if they are a good deal smaller, you probally have the VTEC-E Version.

- Tue Jan 26, 2010 7:45 am #171167 I figured it out it is the d16a6 block stamped d15b headstamp pm 3-4 with a block off plate where the vtec solenoid would go if it was vtec. :thumb:

Least I found a good bottom end to start my build and some spare parts to make some build money :D
