Porsche 911 Valve Adjustment - The Backside Method | 911 (1965-89) - 930 Turbo (1975-89) | Pelican Parts DIY Maintenance Article

Is it worth saying most likely ALL of them di not need adjustment? When I did mine, I adjusted 1 and confirmed with the feeler gauge (adjusted with Kirk tool). I then compared the wiggle on others. If it felt very similar, I just left it. Granted, this was my 1100 mile post rebuild adjust.

Had a few loose ones (was ticking pretty good), none tight.

Yep.

In the 25 years of 911 ownership; and doing the valve clearances each year, I must have only adjusted half a dozen or so.

If they are getting out of adjustment there may be other issues that need to get sorted first.

I decided to adjust all the first time. I did it to get a baseline for my ownership as I purchased my carrera in 2015. The second owner owned it from 93 and had miscellaneous records on the car. The garage that maintained it closed in 2007 due to death of the owner. PO claimed he had the records.... The last adjustment I could prove it had was in 2000 with 49k. I bought it with 67k.

Again thank you all for your help. ��

To the OP, If you can feel the slightest movement after adjusting, with the crankshaft rotated to the correct position for the valve you just adjusted, and with the gauge or whatever you use removed, then you're probably ok. If you have to use your imagination to detect movement, it's probably too tight. I don't bother checking mine with a gauge before I adjust them. As you've read, it's a big source of frustration. Just adjust them all. Check the movement with your fingers, recheck, etc until all are good.

I would not expect a 25 or 30 thousands feeler to fit into the backside.
The proper size feeler is 2-1/2 thou go or 3 thou no go.

I am using the feeler recommended for back method. I typed size wrong what I used was

.0025 and .0030

Instead of trying to get the .04 feeler gauge in right away, try backing the adjusting screw out a couple of turns. That will provide lots of clearance, especially if you reach in and pull back the part of the lifter with the screw in it. That will allow for plenty of room to let the regular .04 feeler gauge slide in easily. Then tighten the screw back down until you get the elusive "slight drag". You can double check it with the go/no go method.
Double checking takes a little longer, but I like the peace of mind it provides.

This is exactly how I adjusted my valves after tear-down and rebuild, worked for me.

By the way, it was an absolute pleasure doing the adjustment on an engine stand...having performed valve adjustments with the engine in and out of the car.

I found the backside method was easiest on the intake valves and the traditional method for the exhaust, mostly due to having the best access from underneath.

Ok, I did it, re did it and did it again. I think I have it.... Putting it back together!!

Thanks guys!!!

Now posting a new question! Lol

OK, you got me! Maybe it's because I'm Canadian- please explain the "backside" vs the "traditional" methods. Thanks.
