Thread: isuzu newbie - insulation? oil choice? tips? etc

Heat, not so much as bother as most comes through the passenger side footwell, from the exhaust. Noise, definately an issue, do it while you have access,you will regret it otherwise, but make sure you arrest any rust that is forming, and prevent moisture retention too. Firewalls love to grow a bit of cancer...
The hole in the bellhousing is a breather/drain hole, and you should only plug it with a bolt when wading or going for a roadworthy certificate.

This is worth more than the purchase price:
Dave's Interesting Things - LANDY4BD1CD
and proceeds keep the forum alive

I use Castrol RX Super in mine.
Good insulation is needed - search for Offender90's posts on the topic.
Heat is an issue on the passenger side. The exhaust is on that side, but is fairly easy to insulate.

I use Penrite HPR 15 diesel.

best way to deal with the noise problem would be to give the county to me and start looking for a V8 county instead :-P

Thanks Mark,

please excuse my slow reply,

re the bellhousing drain hole - when you say wading do you mean like driving along a creek, does it include crossing causeways and going through large potholes/puddles/bogs - it gets pretty wet around here in the rainy season, and some of the many dirt roads aren't the best

as for the firewall rust - yes, i will definiately be rust converting then painting it, before i cover it with anything

I'd buy Dave's Landy CD except that i've already bought manuals off ebay (if only i could get the LR manual i do have to save to my harddrive, setting up a 240v CD drive just to look at the manual sort of defeats the purpose of having an ultramobile pc)

still assessing my insulation options

cheers,

With the wading plug, if the water body (not just splashes) is likely to be high enough to reach the drain hole for more than a few seconds, fit the plug. The main danger is getting water in the clutch as far as I know. So if you are on a formed ford, you'll likely be fine as there isn't much that'll stop you, but for a sandy, muddy or rock strewn water crossing, i'd fit it as the risk of having to stop is greater.

Have a search around.. there are heaps of threads on it. (make sure you check the defender thread too).

Thanks Guys,

I've now found and read various threads on soundproofing - using the right search terms made all the difference - thank-you.

I'd originally only thought of adding heat insulation to engine side of the firewall, but after reading all the posts I've started to think i should be considering noise as well....

However, finding a suitable material seems a little tricky, as there's only about an inch between the firewall and exhaust pipe, it would have to cope with high heat, water and oil, and preferably be not too complicated to apply.... Any suggestions?

Alternatively, having found suitable heat insulation (thou poor sound proofing), i could just leave dealing with noise from the cabin side of things


thanks for the oil comments - i'm familiar with penrite (the oil i couldn't get for the oil change that my motorcycle died on) - this is my first diesel, will probably go for the penrite with castrol as second option

sorry Sprint - you'd have had a better chance before i fixed the head and turbo - anyway i wouldn't want to have to change all those spark plugs...

thanks Mark, I'll get a wading plug and keep it in the car for the rainy season


looking forward to having my landy together so i can finally get to drive it (rather than just talk about it )

cheers, Lis
