Im looking at buying another dc4 integra. I dont really know why, but its at a good price. Now the question i have is that ive noticed the valve cover is different to the one on the 97 gsi i already have.

the one im unsure of has bumps on it rather than just the smooth flat cover on the 97 model i have.

Are they interchangeable? or is it likely that this car has an older motor fitted? Its advertised as a 95 but it could be a december 94 build date.

Any ideas?
