Outer Limits 4x4 Board

1HZ-1HD-FTE have a hump in the rocker cover at the rear, what is the purpose of this and what lies beneath it?

Pic's appreciated too.

the baffle for the oil breather.

not the best pic but better than nothing

here is the underside of a rocker cover on my 1hdt. the rear is at the top of the pic. the metal is the factory baffle which has 2 flaps that can be bent open/closed.

Ok nest Q what would be the effect of cutting the hump off and welding a flat plate, I noticed on DJ Hanson's 1HDFT the breather does not enter at the hump either like I think the 1HZ and 1HDT does but could be wrong

cant cut and weld, the rocker cover is plastic

PCV hose would probably need a catch can or some other baffle to stop oil mist going through intercooler if you remove the factory baffle.

pretty sure mine is (1HD-T) looks like ally when its fitted, but it si way too light and flexy when off. I'll be surprised to find its ally.

Yeah can't say I've ever seen a plastic Toyota rocker cover, come to think of it I don't think I've seen a plastic rocker cover full stop.

A lot of plastics are made to look metal these days, DJ give it a scratch some where discrete you will soon be able to tell.

x 2

The 1hz is plastic believe me...

1hdfte fibre glass
1hdft alloy
1hdt/1hz plastic

wow well there u go, there is a alloy one. Cheers for that Msjc38

X2. 1hdft =alloy

1hz and hdt are plastic, hdft are tough motors, even the rocker is alloy
You could cut the hump out if you like,,,the pipe comes internally from the hump to the front of the cover b4 coming out....u could simply make the outlet up there and put a oil trap external draining back to sump via turbo return

lol ive seen my fair share of burning 70's up in the mines.

Bugger I had the idea of cutting mine out of my FTE and moving to the back like the T and FT. Oh well suppose I can put the welder away and dig out the fibreglass resin.

Gday Fester
isnt the black thing a cover ontop of the alloy??

Hi all...On the FTE the top cover is plastic and the rocker cover is alloy.

Yee har. When it was stated it was fibreglass I assumed we were talking about the actual rocker cover not the stupid rocker cover cover. I've not delved past the rocker cover cover yet but if the rocker cover is alloy then it might still be an option to cut and shut. I want the hump to remain but it might suit better to have it at the back like the FT's to get a better path for the intercooler.

What is the rocker cover cover for anyway. Does it supress noise or does it hide some ugly stuff.

pretty sure its a visual thing, good at hiding oil leaks from view lol
