What's missing on this Viggen motor?

I went to look at a Viggen today and while looking at the motor, I noticed oil coming out of the top driver's side of the motor. Upon looking closer, it looked like something used to be bolted there but was no longer. While idling I could also feel air pushing out of this same hole.

Useless without photos, I realize, but any idea what I was looking at? I'll add images shortly.

My new CSE is also missing that little plug on the end of the camshaft. There was another thread awhile back where people insisted it shouldn't make that much difference, since some cars never had the extra external plug, but if it's noticeably leaking I'd pull one off a junkyard car. Shouldn't charge more than a couple bucks for it.

If the car was an automatic, there should be a vaccum booster in that spot. it's driven by the exhaust cam and helps braking performance. If the car is a manual then there should be a little block-off there

The oil is a mystery

Make sure there is a plug in the hole on the right side of the engine first of all. Also, does it have the PCV #6 update? My viggen was leaking oil from the same area on the engine and after the PCV update and new valve cover seal it leaks little to no oil now. I'm also looking at taking out the plug and cleaning under it. The oil on the power steering pump is probably form the valve cover gasket or leaking out of the power steering line. Those really aren't that bad and should be easy cheap fixes for you.

Looks typical, those cam covers on the top right go old and leak, new ones are cheap and go in easy.
Haha that made laugh, but yea my viggens does the same thing with a new valve cover gasket and there is a plug in the head you just can see it really unless you take the valve cover off. I do believe that the plug has a separete oring too and no one really replaces them. Hell i was just looking a eeuro one night and saw an oring for it so dont quote me on that.

There is no plug that gets bolted in like on the older cars. Instead, there is a tapered cap that is on the inside of the valve cover. They tend to never be replaced, just wipe the oil off.

Thanks for all the replies.

Is it also normal to have felt air coming out that hole at idle? Here's another shot of that hole. Is the aforementioned plug in there?

Also, just as a general Viggen question/comment -*when I took it for a test drive I can't say I was overwhelmed by power. And believe me, I'm not coming from powerful cars. But having said that I didn't really give it a hard gas, as the seller was in the car with me. And said seller is also a pretty big guy, so I don't know if his weight would make a difference. To feel the true oomph of the Viggen, does one need to really stomp on the gas?

Don't get me wrong, if felt composed and torquey. But not in a "wow" sort of way.

The cap looks like its in there, but Ive never felt air coming out of it either. When your "giving it gas" where is the boost gauge? Does it just peak into the red?
 
#10 ·
I didn't really get a chance to "give it gas", as mentioned. Nor did I really pay attention to the boost gauge.

I've never owned a turbo before, so don't really know what to expect. But based on things I've read about the Viggen I think I was expecting a more 'raw' experience. From my test drive it felt powerful but I'd say more sedate than anticipated.

In any case, I'm taking it for a PPI this week, and I'm sure the shop can tell me if I'm missing something in the power department.

From the looks of it I would say that was a replacement engine. It looks like the vac thingy Saunder's was talking about had been there probably on an automatic 9-5 and this viggen locked up its orig motor. I would wonder if this is even an R engine.

If the car's a manual, it doesn't need to be there. You can plumb it into the braking system for extra vaccum assist but it's not really necessary.

There should be a mark on the side of the head and on the block to tell you what's actually installed ...
 
#16 ·
Anything in the history of where the work was done?

Somebody probably had to have known what they were doing. Hopefully it is not a 2.0 from an automatic 9-3.

Where are you and where is the car, also what is the VIN#?
 
#18 ·
pretty sure its a replacement motor as well, good call on that...

Get the Ser# off the block, its OK if it is an R engine from an automatic 9-5 Aero, its the same thing...

Make sure it has teh Mitubishi turbo as well, coudl be a GT17 form an Auto 9-5 if its the 2.3 block or as has been stated a 2.0 motor as well

Regarding quickness, yes these things scream at WOT and 2200+ RPM, take it onto an interstate entance ramp and go see how it feels...
 
#19 ·
I'll have to see if I can get some more seat time and try a WOT onramp. I guess I was driving too conservatively to get a sense of the bat-shit craziness one reads about online.

I won't see the car again before the PPI on Wednesday, but I'll find out in short order there if the appropriate bits are present under the hood.

I'm curious what makes you guys think this is a replacement engine?

What's missing that I see:

1. The battery cover/blanket is missing. If it's an '01 or up it should be a plastic box plastic. If it's a '99 or '00 it should be insulated flexible shaped plastic blanket thing with snaps. That's missing.
2. The throttle body trim piece is missing.
3. The entire air filter box is missing and has been replaced with an open cone filter.

Your specific conerns? The plug with the slight oil weep is correct for a manual transmission car, and appears to be in place. Air that you felt must have been coming from somewhere else. Stick your finger in the hole and you will feel the plug. They all leak from there. Under the valve cover you will find two security torx bits that have been cemented in, assuming it's stock. If the plug wasn't there you'd see oil all over the place.

The other leak at the power steering pump appears to be small. I would bet a quarter turn on the hard pipe line at the top of the pump (can't see in your pic) would fix that.

Ok, just to clarify -- the top image with red markups is from the Interwebs. It's not the car in question.

I don't have a whole-engine-bay shot of the car in question, but here's what I do have. You can click through to see larger sizes on Flickr:

Battery cover is present. Stock airbox is present. Heat shield is present.
 
#23 ·
Slightly misleading? Maybe. The first image I posted has something blocking the hole, does it not? I was trying to show/ask what's missing.

Second image shows a close-up of the actual car, with missing plug missing. In the second image one can also see the heat shield -- which is missing in the first photo.

Sorry for the ambiguity. I was just trying to illustrate visually what I didn't think I'd do a very good job describing with only words.

FYI checked my engine and there is no air coming form that area at all. I did just replace the valve cover gasket so maybe start there and see if that helps. It really shouldn't be a hard fix though if anything is leaking slowly out of that area.
