gang: in my on-going resurrection campaign of the 85 i've pulled all the tin that covers the pushrods and the splash panels from left and right sides (to help w/ access to the exhaust hardware). I finally get to look at that flaky oil press sender-- question is whether i can run around temporarily w/o this tin-- it looks merely to be puddle/splash protection, and i won't be driving in such conditions anytime soon.

I cut my Vanagon teeth on an aircooled 81, so i was religious about cooling tin sealing there, but these wbx panels just seem to be splash protection for the injector gear electrics and the relays/ign control unit on the left side

Any harm running w/o?

Ja, they do that every other night when the beer runs out and the wurst starts digesting.

But what about the tin? Didya catch the part about A: "wbx" and 2: "temporary" ?

I wouldn't go any longer than 8 years, 7 months.
Depends a little on what kind of brine you drive in in the winter.
I had a little trouble with the connection for the Digifant temp sensor at the thermostat housing being corroded on two of mine about a year ago.
Oh, hell, that one wasn't covered anyway!
The Subie waiting on the shelf won't care, in my case.
This is typical of VW engineering- totally anal in some respects, yet don't even address the major flaws in the engine and tranny.

Mine have all been off temporarily for 9 years, 4 months. I temporarily threw them in the shitpile the minute they came off. They're still temporarily in the bottom of a landfill somewhere.

Honestly, I think the engineers just stuck them on there as a matter of habit. It took them 7 1/2 years to finally say "Was haben wir gedenken?" ("Vat vere ve tinking?" ). By that time the wbx was out of production.

They serve no useful purpose I can ascertain, unless it was deemed useful that the engine should be extra-hard to work on. I drive thru a creek crossing daily to get to and from my home, with the water 2 feet deep, rushing and full of big chunks of ice in the winter, and no silly splash shield is going to keep the engine dry under that kind of use. I have never experienced any detrimental effects due to this "abuse".

Chuck 'em, I say.

I'm going to chime in as someone who likes to drive my WBX with 4WD engaged, on RCKYRDS.

I think the tin serves a crucial purpose by being a superb first defense against errant ROCKS being thrown against the weak, thin, poorly designed *pushrod tubes*.

Of course, if you never drive on gravelly or rocky roads, you never have to worry about that, right?

...my 2 cents.

Oh, and they look great by showing new leaks when powdercoated black.

Yes, there is the protection from the stray rock thrown up by a tire, but I live up a fairly nasty road, and explore on much worse, and it's never happened. It could, but never has. For me, I'm willing to trade that tiny risk for having good visual access to the whole engine. I want to see leaks where they start, not secondarily where they drip onto something else. Besides, that's why those awful VW repair tubes were invented (you know, the ones that leak more than the leak you were fixing?).

Then there's the tubes themselves: I don't use the stock tubes anymore, as of 1 1/2 years ago. The heavier aluminum telescoping tubes I use now would sustain a rock hit pretty well, so that's a moot point for me anyway.

Them's them.

So yeah, to be totally fair there is some protection afforded by the lower plates that cover the tubes, but as for the shields that go around the sides of the engine bay, they just seem to make it harder to work on the motor. So to the original question, keeping the tin at all is optional.

Maybe they put them in to fool unsuspecting aircooled fans who didn't know that the new motor was watercooled.

danocox Mon Jun 25, 2007 10:52 pm

ya subaru does the same thing, just connected to the frame. they protect the case from water and debris that could harm the engine, that is the only reason that they were put on. do you need them? I dont know, seems like many people have done fine without them.

Bambus Tue Jun 26, 2007 8:35 am

thanks for the confirms, lads. Although as soon as i had the lowers off i did see them serving as a very light duty bash-plate of sorts for the pushrod tubes. That kind of exploring is one of my fave attribues of the bus/Vanagon, but realistically, i'll just be glad to get this thing operating soundly on the damned tarmac, forget offroad.

Same here-- i guess i've been too spoiled by working on cycles the last several years, and don't have as much patience with 4-wheelers as i once did. When these tin pieces were out i flung them into a brand-new shit pile made just for the occasion. Flung, when "put down nicely" would have sufficed. Ahh wrenching in the Florida summers.

Laters,

You forgot about "III". How cool the shields would look if they were polished. I have often wondered how long I could have them off wilst I did this.

Thanks Guys.

BTW...Why not have them on there anyway? I do a lot of off-road driving.

pete000 Tue Jun 26, 2007 3:27 pm

I was just looking at those wondering the same think. I am probably going to ditch mine shortly. I also do not drive on gravel roads.

I am excited to think how much faster my bus will be arter loosing all those ounces !

Ahyup. I had to hunt far and wide to find a telescoping tube that would work on the wbx case. The aftermarket tubes are intended for Type 1's, which normally have 21mm OD on both ends. The wbx tubes are 21mm at the head end, but the case end is 25mm, for reasons unknown. But, some of the aftermarket tubes are made to be used with high-ratio rockers, so the outer ends are made larger to clear the pushrods better. So I called CB and had them measure the Jaycee tubes, and it turns out that the outer ends are 24mm. They include some washers that back up the seals, so if you invert these they fit a wbx real nice. If you had to buy a new set of wbx tubes, these are actually about the same price, but much more durable and easy to repair if you have any leaks. Mine have been on there a year now and never a leak. Pretty colors, too.

I would actually consider putting the lower shields back on (if i still had them) if only they didn't attach at the exhaust port studs. But I'm not of a mind to have to remove several of the exhaust nuts just to have access to the engine, and as I don't see a strong need for them to be there, they stay off. That way, I can also loll around underneath and gaze at my pretty pushrod tubes.

Alan Brase Tue Jun 26, 2007 9:22 pm

I'm with you on the unhappy means of attachment by the exhasut studs.
I suppose the WBX pushrod tubes are bigger than type 1's because the lifters are bigger diameter. Remember, the type 1's use nail type followers.
Has anyone ever seen the tubes for the 1980 Vanagon 1.6 engine? CN, maybe? I suppose it is the direct predecessor of the wbx.

I just pulled mine off last nite, Easy to do. I was suprised to see the previous owner had all the exhaust mounting hardware replaced with nice stainless complete with anti seize. Made it a snap to come off.

All my tubes are dry and clean ! I can see why VW engineers put these shields on there as some of these vans were used in extreeme off road conditions. Mine never will.

I also noticed the engine seems ever so slightly louder at idle. Those shields are double thick and might provide a bit of sound proofing. Might just be me.

I think I will throw thses shields in the pile of stuff going to the powder coaters. They might find their way back on some day.

I think I'll change out my hardware too after polishing the shields. I see a value in them. They make nice rats nest too.

I use the splash guard to hold up the oil pressure sender for my VDO gauge. Got the kit at Van-cafe.com. (Only one wire connected in the pics, because I was in the process of hooking it up. One wire goes to the idiot light, and one to the analog gauge.)




I've also noticed that the engine is a little more noisy with all the tin removed.



An an old VW guy told me that polishing valve covers won't allow them to radiate as much heat, and that painting 'em black will dissipate more heat from the engine. I don't know if it's true but painting all the accessories black allows them to match my black oil filter, and newly painted engine support bar and intake plenum, etc.

riceye Wed Jun 27, 2007 7:24 pm

I've got an extra set of aluminum valve covers in a box somewhere. Might drop the oil temp a half a degree or so!

They'll probably stay in the box....
