Title: Took my measurements today........
Post by: Firehawk068 on March 31, 2013, 10:56:26 PM
Started by cleaning the top of the engine...........which consisted of 3 cans of brake cleaner, and a bunch of compressed air.

Removed the Valve cover bolts/grommets........Then a rubber mallet to dislodge the valve cover.
Pretty clean in there considering the mileage.........

One of the first thing I noticed, is slotted cam gears..........I didn't think they came with these from the factory? I couldn't see any name on them? Since I'm the second owner, I'm guessing the first owner had these put in when he had the top end serviced at some point?

Next I pulled the plugs......I put these in about 3 years ago......

I also marked the crank rotation, so I wouldn't accidentally turn it the wrong way and F it up.

(http://i859.photobucket.com/albums/ab154/firehawk068/FJ1200%20Projects/Valve%20adjustment-HID%20headlight-Heated%20Grips-etc/P33100252_zpsf4f43279.jpg)

Next, I laid out my worksheet, and my feeler gauges.

(http://i859.photobucket.com/albums/ab154/firehawk068/FJ1200%20Projects/Valve%20adjustment-HID%20headlight-Heated%20Grips-etc/P3310032_zpsb53581c7.jpg)

Before I started measuring, I used a fine honing stone to smooth off any burrs off the leading edges of the feeler gauges, and used the micrometer to check the accuracy of said feeler gauges..........I found a few of them to be off, so I re-marked them.....

(http://i859.photobucket.com/albums/ab154/firehawk068/FJ1200%20Projects/Valve%20adjustment-HID%20headlight-Heated%20Grips-etc/P33100262_zps4567cb93.jpg)

I used the "Cam lobes pointed 180 degrees away from the valve" method, and went back around and measured them all a second time to verify my measurements.

Turns out that only 4 of the intake valves are still within spec.
The other 4 intakes, and all 8 exhaust valves are too tight.......... :negative:

Next up is using the tool that Lee C. let me borrow, to take the shims out and mic them. See how many I can get away with moving around, then hopefully finding a shop that will let me exchange some or all of the rest.  :scratch_one-s_head:

Way to go Alan, slotted cam gears very nice, if you get a degree wheel then adjustments can be made for stretch in the cam chain. :yahoo:

Presuming your timing is stock, it's interesting to see how far to one side the exhaust sprocket is.

Thats the first thing I noticed? And I was wondering about that myself?
It would be interesting to put a degree wheel on it, and see what the cam timing is set at?
When I bought the FJ, the previous owner said he had the top end of the engine done by a guy who builds Legends Car engines, but thats all the information I got from him.
I assumed it was a shop in Phoenix, but it may not have been.

I will tell Lee that you guys said HI.
