911sc Valve Adjustment?

[Targa911SC]

I have an '82 911SC. Are the valves self-adjusters or must they be done manually? How often? If so, what is the setting? Thanks, Lars in Boise

993s are hydraulic. You will need to adjust your valves. It is a highly pleasurable DIY job on these cars. You will notice immediate improvement.

Do a search here
Buy the tool (feeler gauge with extra blades)
Watch the videos
Buy Wayne's book
Take your time

Agree, but still expect to feel like an idiot with ten thumbs the first few you adjust.

LOL @ 10 thumbs!

I swear...I am not an idiot....and someone besides me can vouch for that...but the first time..WOW!! took like 30 minutes to set one valve....and I had to redo it 30 minutes later!

now its really simple....the learning curve is fast and steep.

Agreed, and one of the keys to the learning curve is the factory +/- .002 factor of the .004 gap - with this firmly in mind, the struggle is much less (for me, I would adjust if under by .002 but would not adjust if over) . . .

[Farrell]

so, is .004 the only size gauge you will need for all the valves? i bought the curved one off of pelican and i only have 1 blade of .004. do i need multiple blades for a valve adjustment or will the one do?

thanks!

Rite of passage for a 911 DIY. If you cannot handle this task, don't work on your 911. Then you graduate when you can do a cam timing on a 911. That also means you have taken your engine out of the car.

That's the only gauge, we don't work with under/over specs, it's match the .004 and move on.
Although, the factory spec is .004 plus/minus .002, so there's a lot of slop allowed. How much slop anyone accepts is how much time they want to put in, and hoe flexible they are.

[Farrell]

good stuff, thanks much!

Murphy's law: BTDT

If you got only one, you will break it (bent out of shape) on the first few valves.

If you got spare ones, the blade will last for a few Valve Adjustments...

so very true, they are cheap, so i tossed a few in my cart the other night since i need more parts anyhow.

Sorry to open such an old thread... A few days ago I performed a valve clearance adjust. Now engine only fires on cylinders 1 and 4. Other cylinders not firing at all. Theres any chance y did the process wrong like for example TDC on 4th cylinder???
Kind regard

Pop the distributor cap and turn the engine so the rotor points to #1 and see what you have on #1. Then check the rest. Then there's the plug wire mix up trick.

[David Inc.]

Did you remove the plug wires at the rotor? #1 and #4 will fire even if you put the plug wires back on in reverse.
