The problem is that my crankshaft only rotates 1/2 a turn and then opposes resistance and goes back to is initial position. So it does not go anywhere.
I want to mention that my car is currently parked on ramps, oil was emptied, parked in 1st gear and with the handbrake on. It is an MSG.

Any ideas?
Had the same issue with my SMG, need to put the car in neutral.

^^^^Yup! Me too.

Thanks to OP for taking a daunting job and making it very straightforward!

If anyone else has read this far, a couple tips.
Ramp your car first and drop the splash pan (it's not mentioned explicitly). If you drop any tools, easier to pick them off the floor than fish around in the splash pan with a magnet......also, you'll need access from below to get at the lower rad shroud fasteners.
Remove the airbox, again easier access to the fan shroud fasteners.

Already had the car apart doing the Beisan stuff. Watch the videos and used your sheets and this was a breeze. Didn't really even read the steps, videos said it all. Also phone a friend a few times to make sure I was on track (subjective things like how much drag there should be etc.). Thanks!

Thank you very much for this great DIY. Just finished valve adjust this weekend using this DIY.

It was spooky when I finished with everything back together it seemed too easy somehow. I spent a lot of time doing it (~12 hours), but I went slowly. I do think that the removal of the fan shroud (and belly aggregate panel) should be earlier in DIY, step 1 or 2; but it worked wonderfully and the steps were very clear.

Thanks again!

One question to you guys on this thread, what kind of lint free rags did you use? Im having trouble looking for some.

Sorry if i missed this somewhere, but does the fan have to come off, or it just makes things easier removing it?

Great write up! going to be using this soon.

The fan does come off in the DIY (step 36).

I recommend doing it earlier than it's place in the DIY (perhaps first thing) because the aggregate pan needs to come off to get to the bottom passenger's-side fan shroud screw. The pan's rearward screws are a long reach under a car that isn't raised. Also it seems better to keep additional tasks to a minimum while the valve cover is off. No point risking stray debris and whatnot.

There might be a good reason to do it so late, but I can't think of one.

Hi,

Thanks for the great write up. It is very detailed.

I am in the process of doing my valve adjustment now, but I have some confusion in regards to clearances.

A couple of my valves seemed to be on the edge of spec. For example, in using the "go or no-go" method of measuring, I found that cylinder 6 intake valves were just barely out of spec. I was able to insert the .007in shim, but not the .008in shim. So we can say I have .0075in clearance. Since the clearance needs to be .008in at least, I decided that I should adjust the valve.

The problem is that the replacement shims are in .04mm increments which is 0.0015748 in inches. The current shim on the valve is 2.24mm. If I go one step down which is 2.20mm, the gap is too much and out of spec (.009in shim can go, .010in shim is no-go).

What should I do? Can the existing gaps be considered in spec?

Any help would be very appreciated. Right now, the car is apart, and I don't know what to do. Please advise.

Thank you.

--Kiran.
