Troopy Snorkel

G'day John.

Ok, so it's yet another unexplainable Troopy squeak/rattle...

The only other thing that could be causing the rattle is the drive's windshield so I might have a play with that. I've wound down the window and held onto the windshield to see if that stopped the noise and it didn't but I'll have a closer look.

Thanks for the advice on sealing the snorkel. The Toyota snorkel does appear a little flimsy compared to some of the aftermarket snorkels so I'll have a look at that on the weekend.

What's your opinion on extending the breathers on your diffs?

I know a lot of people do this but the Troopy has the valves that are suppose to shut (assuming you clean them once in a while) when you do a water crossing.

one at work same as yours was split along the underneath of the arm that goes along the gaurd, saw it by chance could pay to check it thoroughly all over before doing crossings

Yeah, I'll follow John's advice and seal it up so if there's any spits I should find them then.

Thanks Davoe

The point about piece of mind makes a lot of sense. This is something I've been meaning to do for a while now but haven't made the time to do it because I haven't been off roading. That's hopefully about to change so I better sort it out. I've also been told there's a breather on the top of the gearbox that can be extended so I'll look into that and make sure that this is extended if possible when the gearbox is removed next month for a clutch upgrade.

Will do with reagrds to the sealant too. Cheap insurance for what could be an extremely expensive mistake.

I was on the TroopyOZ list for a while but I've changed email addresses recently so I haven't been receiving any messages. I'll update my account details at Yahoo because I'm just about to tackle the wheel/tire argument and I'll be after some people's experience in this area specific to Troop Carriers.

Thanks for the advice.

This could be induction noise but if it is it wasn't there two weeks ago so I'm a bit concerned something's going on. The rattle doesn't occur at a specific RPM. It basically becomes apparent when you tread on it hard but it's volume is relative to RPM - the higher the RPM the louder the rattle. Back off the throttle and the rattle is gone.

Jezz, I hope I don’t get attacked by Hornets when I'm checking it out.

Thanks Bob.

PS. The Troopy drives much better after re-packing the wheel bearings a couple of weeks ago. Thanks for the advice on tensioning the bearings back then. The brakes are great now too. Keeping grease up to these vehicles appears to be a major factor. I thought my rear diff was on the way out 6 months ago until I had a mechanic take a look at the vehicle. A bit of grease in the tail-shaft and the problem was solved.

Good to hear you got the wheel bearings out of the way, Manic. We've a couple of sets to do here soon too.

Yeah, that grease is good gear. Dirty, but a lot cheaper than bearings, and other parts.

Just thinking about your noise proble, while reading your replies above. The aircleaner itself isnt lose on its mountings, or cracked anywhere? If the dome on top of snorkel has been hit, it maybe cracked enough, to set up a harmonic?

Sounds like a mystery,

Hooroo...

Hi Bob,

The induction noise was mentioned on 70scool - seems almost universal with the 78/79series TDs. I think a couple of people have been told the noise emanates from the fuel lines and the noise was resolved when Toyota fitted an accumulator somewhere in the fuel system. I only get the noise when its relatively cold, so haven't bothered looking for a fix.

Sounds different to Manics problem. Maybe a Hornets nest too :-))))

Cheers
Phil

G'day Phil and Bob.

One of the first things I did was remove the air filter to see if the noise wasn't coming from there from the filter being damaged. I really can't see how you would damage an air filter that's 3 months old - city driving only. Anyway, everything appeared Ok but I didn't really have a good look that the cleaner mountings were solid.

I'll have a look this evening when I find the bug spray, safety glasses and a good pair of gloves to protect me from the Hornets ;-)

She's off to the doctors tomorrow for a new timing belt and a quote on a clutch so I'll mention it to the surgeon and maybe he'll find something while he’s at it.
