Valve/Cam cover gaskets......

[Meaux]

Are they hard to replace? Drivers' side looks to be a pain. Tightening would most likely make it worse.

Mine drips onto the exhaust when engine is cold, goes away when warm.

Thanks.......

Ive done the covers, and its not bad...

You dont want to tighten them becuase they are not on that tight to begin with...

Thats odd that it only happens when cold, generally its when warm...

I say go ahead and see if they will cinch down a bit. If the gasket has shrunk it's taken tension off the bolts. Totally OK to take the bolts back up to torque spec, around 5 ft-lbs, if they're looser than that.

With all those cars and 2 Porsches you can't be a stranger to DIY work! Plan on taking a day or 2 if you want to replace the gaskets, and one of our sponsors is more than likely cheaper than your local dealership. http://www.everythinginfiniti.com

Mundane detail but its 9 ft-lbs.....

Ive found that using one of those little tiny 1/4 in drivers tightened firmly gets you about where you want to be...

I can't believe the '94s would be that much higher. Are you certain? That would require a grade 9T bolt 20% larger in diameter.

I noticed on the 9093 (if memory serves) uses bolts.. The 94 has studs with nuts that go on them...

Hers a diagram from the FSM.....

I'll see how loose they are tomorrow.

No, I'm not a stranger to DIY car repair...:-) I've been maintaining the 89 Maxima for years...My wife can't kill it...201Kmiles and still runs great.

Hell, I own a 72 Porsche 911, and you don't tighten those cam covers, you take em' to a machine shop and have them shaved flat....worse thing you can do is tighten them suckers...over 4ft. lbs. is too tight.

How else can I justify not hittin a lick!

[DAEDALUS]

My bad Wes. I will become familiar with the '94 engine soon.

Meaux, how do you like your '72 aside from the maintenance?

[Meaux]

DAEDALUS, a 72 911 is a crude, "seat of the pants" kinda car. You must pay attention at all times, even though it's only 150bhp, it is really easy to speed, it loves high revs, it's hard not to hit 6000rpm because it's so much fun, and cops will turn around just to pull you over. Never lift in a turn, just grit your teeth and nail it. If you lift, the weight shifts, rear end losses traction and wants to swap ends with the front. Really, by todays standards, it's a dangerous car, in more ways than one.

I love the car because I worked at a Porsche+Audi dealership in the 60's and 70's, saw em' come off the truck new. I once had a Conn. State Trooper tear up my license after I blew thru town in a 914/6. Had to get married before the State would give me my license back.......

After owning a few Datsuns, Hondas, Nissans, and the Q-Ship, I wonder......"What German Engerneering"?

LOL.. I hope you didnt tell your wife about that

Let us know what you come up with for the valve covers.....

[Meaux]

elwesso says, "LOL.. I hope you didnt tell your wife about that "

No, I didn't, but it didn't work out anyway. :-) I left her for Texas 4 yrs. later and told her, "send me the papers when you get around to it". She was a real"sport" :-)

Well I checked the covers w/ a 1/4 screwdriver type handle (the kind you can't get too tight), and only found one on the drivers side bottom/middle that I could tighten. Started the car up and no leak......I'm really not under the impression I fixed anything....we'll see. I'm sure at some point it will leak again.....

Just for grins, I ohmed out the TPS, and it's like an on/off switch. No gradual reading, one way or the other. Is this normal? On the top 2 pins, it's "made" till the T-valve opens 1/8 of the way. on the middle and bottom pins it "makes at 3/4 open. I'll bet I didn't make any sense.....:-) I had a high idle 1200rpm till I moved the TPS just a tad. Shifts better now, but I'm not convinced everything is "right".

[DAEDALUS]

There are 2 sets of connectors off the TPS body. One is for the TPS, the other is for the throttle valve switch. The TPS is variable, the throttle valve is on-off. Sounds like you measured the latter. The one with the harness is the one you want next time you're under there.

[Meaux]

I hope we're talking about the same sensor......My 94 Q only has 3 wires with 1 plug on the TPS........

[DAEDALUS]

The one with the harness is the one you want next time you're under there.

[elwesso]

They use the same "sensor" but there are 2 different harnesses.....

You need to ohm it when the car is idling and its connected..... Take a small pin and stab the wires..... Unless daedalus has a better method (most likely)

[DAEDALUS]

No ohming anything with power connected! Ever. Take a voltage reading if you want, but not resistance. The reading won't mean anything and you could maim the meter.The component measurement in the FSM gives ohms, so you can (should) disconnect the harness completely and measure at the pins on the component. Move the butterfly plate manually and see how the resistance changes; compare numbers to manual.That isn't the only source of problems though...component could be fine, but there could be a problem with the ECU or the harness. If you want to go all out you should check the voltage by backprobing the harness on the ECU, this time with the car running. Again, values are given in the FSM for this approach.Note that the TPS itself has its own harness that hooks to the main one; the closed throttle switch doesn't.

[Meaux]

I know better than to "ohm" anything with the power "on", or stick holes in wires....because with my luck, the meter would survive but the ECU would become terribly confused and I'd have more problems than I have now......I'm gonna leave well enough alone, check mileage, and if it's OK, then the heck with it.

I have alot more work to do. I think I've been avoiding pulling the gas tank on the 72 911 to Por15 the inside, due to rust, lowering the rear and replacing the motor mounts on the 968, and to top it off, the master cylinder went south on the Ford truck..... what next?

I wish I hadn't let my wife talk me into buying in a fancy subdivision, where you can't do anything in the driveway. I'm used to 2 acres and a 4 car detached garage in Texas) This dang house has only a so-called 2 car garage, (maybe I could get 2 Minis in there) hell, I thought everybody jacked up their cars in Alabama!!!! :-)

[Meaux]

Thanks for the picture elwesso......who has a FSM on CD at a good price?I found the 968/944 CD's for $30, and the actual "books" (many volumes) were something like $300.

I have a 89 Nissan Maxima FSM that I bought at the dealer in 89, and alot of the parts on that car seem to have the same functions as the Q45. I'll have to read more on the 89 Maxima TPS install................I did replace that TPS years ago.
