Take off your Engine cover!

[critta11]

So I was loosing boost a little while Ago in my zd30,and found that the engine cover had worn holes all along the fins on my factory intercooler. I highly recommend taking off the cover so that this doesn't happen!!!

[Stropp]

ah thats the good thing about the old rattly 4.2 no engine cover so you can see the beauty within :thumbup:

[stumpie]

I have had my cover of for the last 3 years as recommended by a diesel mechanic who specializes in patrols.

I found mine was rubbing a hole in one the hoses to the catch can.

[threedogs]

read somewhere you put washers under it to space it up, for what reason I don't know.
I did power file mine so the catch can hoses didn't foul on the cover

Mine had to be spaced up a bit due to the boost adapter on the intercooler. As soon as my new IC arrives the cover is coming off. Not really sure what the purpose of the cover is anyway.

[threedogs]

I think so the air from the scoop is concentrated over the IC area,
saying that I don't know how the EGTs would go with the cover off

[Hodge]

Makes one winner if taking it off would jeopardize the EGTs then.

[paulyg]

Would the rubber gasket on the scoop still seal on to the intercooler with out the cover?

[threedogs]

critta or stumpie should know that, if they have gauges fitted
would be interesting to find out

Not interested in my Troll looking perty, its a bloody 4wd.
If I wanted something perty I would buy a Freelander or a Rav4.

Seriously ???? Rav4 ?? Even TD wouldn't be caught dead in one of those..... mmmm but then again ;) :)

More of an Evoque kind of guy.
Just thinking in OE guise with the cover off would the IC be as efficient

[meh]

Took mine off. Just a pain, more bolts to take off each time I fiddle with things or when parts break. Plus it didnt fit too well with the bigger intercooler on.
EGT's have been NO difference what so ever. Mine is NAD'd with the EGR blocked running 19psi. Sits around 200-250 around town. Had a car full of 5 people loaded with all camping gear down the mount lindsey, in 5th gear up the hill at 100km/hr highest it got was 398degrees

[threedogs]

@ MEH what motor?? Di or Cr

[meh]

The wonderful zd30 Di

The only reason for the cover is sound. It's supposed to block out the top end diesel rattle. This cover was the first thing I took off when I got my troll.

How are you getting 19psi whiteout hitting limp mode every hill? Mines at 15 and even then hits it every now and then up a hill holding 3000rpm

Not sure ?
just followed the instructions on here to set it up and crept the boost up. Get full boost by around 2500rpm. Drives great, plenty of torque with no lag

Just checked this in the car, full boost is actually around 1700rpm

[Hodge]

Is yours a crd Meh ? For what its worth , after I fitted the boost control I was hitting 19-20 until I fine tuned the Dawes down to 16. And never got limp mode.

Is yours chiped? Would that change when limp mode comes in?

Yes it does bud...

Dp chip but that doesnt affect that. I have the HPD hi flow air box lid and maf housing which does allow me to go beyond the stock limits.

Yeh heaps less restrictive especially if your running a 3" exhaust
Have you got a hi-flow snorkel?
