HEADS

Chrysler has used several heads on the 2.4L along with some additional variations, depending on the application.

1995-2000:

The first head that was used from ’95 through ’02 was a 4667086 casting, but we catalog the two different part numbers because of the cam change in ’98.

2001:

The original head was replaced by the 4667086AB casting in 2001. It had smaller exhaust valves, smaller, rectangular exhaust ports, two more bolts (10 total) for the exhaust manifold plus one more for the intake manifold and one more for the rocker cover. There was also a pronounced bulge added to the head on the driver’s side, between the third and fourth chambers.

2002:

The oil return hole in the “bulge” on the driver’s side was enlarged in 2002, so the casting number was revised again; it’s a 4667086AC or AC-J now. All of the ’02 cars and minivans with this head appear to have had EGR, so we drill the hole in all of them, but we include the Chrysler EGR block off plate (p/n 4591803AA) and gasket (p/n 4861535AA) along with the engine just in case there’s an ’02 application that came without EGR.

2003 w/o Turbo:

None of the ’03s had EGR, according to our research, so we use the 4667086AC-J castings without EGR for all ’03 applications or build the engine with an EGR head and install the block off plate on it.

2003 w/ Turbo:

The turbo engine was available in the SRT4 Neon and supposedly in the PT Cruiser according to the AAIA list of VIN codes, but there’s nothing listed in the Chrysler parts book for a ’03 PT Cruiser with a turbo, so we don’t think it really exists. In either case, the turbo motors would have had the 4667086AC-J casting that came with special exhaust valves and no EGR in ’03.
