HOW TO - Tell a KLZE from a KLDE
How to tell a KLZE from a KLDE:
KLZE will have:
**-**KL31 xxx marked on the heads
**-**KL01 or KL31 stamped on the camshafts [KL01 for ZE's from Millenias, and KL31 for ZE's from MX-6's]
**-**Square runners, either curved neck [Millenia] or long straight neck [MX-6] manifold.
**-**No EGR port on the rear exhaust manifold is definately a ZE, though some ZE's have come with EGR.
KLDE will have:
**-**KL xxx marked on the heads.
**-**Round runners, short necked manifold
Both can have Ford OR Mazda valve covers.
I've also seen a few KLZE's with KLDE intake manifolds on them.
The main thing is going to be the head code. That's going to tell you what's inside.
