Topic says it all. The engine is an D16A1 from an 87 Integra.




The shorter ones have "AT" stamped into the heads. There are 2 long ones and 4 short ones. Did Honda do this for balancing reasons?

I am about to have my whole rotating assembly balanced, so I guess (?) order doesn't matter since it will be taken into account.

Thanks,

They should all be the same size. All auto bolts are shorter then manual ones

 

I thought that the AT might stand for Auto, but this engine came from a car with a manual tranny. I pulled it myself. Hmmm...I guess this means that someone worked on the engine/tranny before I did.

No biggie...I'll just buy new ones. Thanks for the response!

The auto tranny equipped CRV motor I bought a while back had "AT" on all the flexplate bolts. I bought all new manual tranny ones.

 

dont use the at bolts if you are using it on manual tranny. the at is for auto transmissions

 

I'm just going to buy a set of 6 new ones. The heads on these are a bit rounded off anyway. Whoever worked on this thing before I got it gets a .

Thanks,

Yeah, that **** look pretty bad.

AT does stand for automatic.

Putting in the clutch?
