Someone repost that melted Volvo valve cover, gets me every time.

On the Volvos it's actually more of a cam cover since the cover houses the top half of the camshaft bearings :science: and therefore uses no gasket (only anaerobic sealer)

They're all aluminum, IIRC it was the coil sight cover that melted on the Volvo. Still an awesome picture nonetheless

It's the cosmetic coil cover, yeah. The metal valve cover is visible above and below it. As far as I know Volvo valve covers are still all metal, the idea of a plastic one seems... weird.

So? If the manifolds were mounted the other way, it would be the exhaust copping the damage. Can't see why the intake taking the damage to be any worse, either way the car is hosed.

I hit a deer a few years ago in my Zetec Focus (front exhaust/rear intake) and the top half of the radiator got pushed back into the header. Aside from some plastic from the radiator fan melting upon contact with the hot exhaust there wasn't any actual damage to the header/cat or engine (still runs fine today.)

Regarding the metal vs plastic valve cover debate, my Focus uses a plastic cover, and AFAIK every Ford I4 since the early 2000s has as well - the 2.5 Duratec in my company car (2012 Fusion) at my last job used a plastic cover.

What's bizarre is that the toyota passenger cars still use alloy covers (well they did as of early 2011), yet the diesel vehicles like hilux, land cruiser, hiace etc have plastic covers.

Re: PVC Intake Chat

Who says you can't use PVC for proper intakes?

rcman50166 posted:

Update (finally):

The intake addition has been completed.







I might as well take the time to go into detail of what it is for. The stock ECU contains a table with intake flows and associates them with a specific pressure read by the MAP sensor. Honda's ECU is proprietary so we can't simply go into it to read it. So we have to get that information the same way Honda originally did, by measuring it using some sort of flow meter. For ours, we are using a Venturi flow meter that uses Bernoulli's principle to calculate the velocity of the flow. Multiply that by the cross section of the pipe and it becomes volumetric flow rate. Multiply that by the density of the air (calculated using the IAT or intake air temperature) gives you mass flow rate. This is exactly what is needed to figure out how much fuel to inject using stoichiometry. The rest is all timing done by microprocessors. We tested the assembly using a shop vac. Did you know they suck at about 10 gallons per second?

TL;DR:
Hey look at the red dong we added to the engine. We had to because Honda is all secretive about their stuff.

This was from the now dying SAE thread. To be fair, it was not meant to be anything but a prototype.

The reasoning behind this was thus: plastic cam cover is cheaper and lighter and better, so we'll use that>need foam to silence those tappets and injectors because the market is moving upward for landcruisers and people expect it!>poo poo better put a steel cover over this, it might get damaged if anyone uses this thing seriously!

I think it is more like: The price of plastic glued to steel is less than a thick steel one itself, and it still looks nice from the outside.

You'd be happy with a GM. They're just dummy gauges in the recent ones. By the time they go over 'middle', your head is (likely) already warped. They work real well for finding stuck-open thermostats, though.

I've never seen the coolant temp needle go anywhere above 90°C on the gauge in my car, but the oil temp needle goes all over the place depending on how hard I drive. It's nice to know that it works.

Actually, I kinda like how the normal operating temperature range is marked out on the gauge. So oil needs to be between 90°C and 140°C, while the coolant needs to be between 70°C and 90°C.

General_Failure

I think there's a layer of abstraction between the needles / lights and the related sensors on the Fairlane but the temperature gauge has definitely been calibrated so normal range is acceptable more or less but as soon as the needle crosses that line in to the H lands you're poo poo out of luck. But there are two kinds of hot. The needle getting up in there and when the light at the top of the H illuminates. That light is usually accompanied by a bone chilling alarm tone and the roar of coolant violently escaping form somewhere.

I have to go for a drive today. Hopefully there won't be any mechanical failures. I always do a pre-drive check. I'll be giving it it's first hopefully problem free run on petrol in a long time.

I've popped heads with the gauge sitting dead. loving. center.

as soon as the gauge gets 2/3s of its sweep there is *something* under the hood that is already boiling its tits off. Gauranfuckingteed.

I *really* hate land rover temp gauges.

I blame you for the trend of gauges which always point to a single reading no matter what the actual reading is! Well, OK.. maybe not you but instead those who would take their car into the dealer to complain about it overheating when the gauge goes ever so slightly up when they are running A/C at idle on a hot day.

My VW temperature gauge stays pointed at 190F when the actual coolant temp can be anywhere from 175-210 (that's as high as I've seen it go since getting my scangauge mounted, I'm sure Texas summers will make new records). That is pulling off of the OBD-II connector so the engine knows the right temperature but just isn't showing it :argh:
