Just finished STick's adjustment. First time for her in ~130,000 miles. She's had one tight intake (#1 front) for quite a while, but only .001.
So, this check showed 8 tight valves, that particular one tight by .003. Time to bite the bullet, put my nose to the grind stone and shoulder to wheel. (Just try working that position! )
I did ReSTored last week, changed 12 shims but none were that far out.
Turns out #2 front intake was also at .003, and rear was .004, #4 intakes were .005 and .005.
#1 Exhaust front was .008, all other exhausts were right on.
So, all 4 left side intakes, 3 right side intakes, and 1 right side exhaust, 8 total.
Largest shim (225) was in #1 front exhaust, changed it for a 220.
#1 front intake had 215, changed it for a 208, #2 front intake had a 205, changed it for a 198 (3 sizes smaller each.) Thanks to John Oo for the tip on how to select the correct size. Each of the other changes were similar, one or two sizes smaller. Mark's loaner kit plus the shims I contributed from The Hulk provided everything needed.
Previous discussion about changing out the timing belt (and a couple folks discovering their's were off by 1 tooth) had me looking closely as I took her apart. All was (is) good.
After many years and many miles with no changes needed, I was surprised to find so many tight. Can't be because of carbon build-up, that makes valve shims loose, not tight. Standard answer is recessing valve seats. At 184,000 miles I guess that's not unreasonable. Last check, tho, was not that long ago, what would cause'em to change so quickly?
Anyone have a guess as to how many more miles she has in her?
Timing belt, water pump, and idler pulley next week.
ReSTored has the duty for Christmas STOCing this weekend, hope to see a bunch of ya there.
