I need a micrometer to measure camshaft lobe height, journal diameter, and the thickness of valve clearance discs. Would this set give accurate enough measurements? http://www.harborfreight.com/3-piece-micrometer-set-66512.html?utm_medium=cse&utm_source=nextag&hft_adv=40011&mr:referralID=5a9c804a-…

A jig would be required to measure cam lobe height. And for the DIYer the Harbor Freight 3 piece gauge set might be accurate enough. When setting valve clearance using shims it’s usually a matter of assembling the valve train without shims and measuring the clearance with a feeler gauge and installi…

That $25 caliper should do just fine…

“A jig would be required to measure cam lobe height.” Really? Could a jig be attached to the caliper posted above? "Does a shop manual indicate measuring cam height?’’ Yes, Haynes. I’ll be removing the camshafts to replace stem seals and figured it would be a good time to check the camshafts ''…

Dear mystic, It is useless to ask people here if the measuring instruments that you suggest are accurate. Even if someone owned one identical to what you post, yours may be different; it is not the same tool. Nobody can sit in a chair at a keyboard and predict that a low cost measuring instrument…

Wha Who? I understand what you’re saying and I do plan on checking whatever tool I end up with to make sure it’s measuring properly before using it.

Camshaft wear is usually quite obvious. I’m curious as to what results the OP desires beyond setting the valve train clearance.

If you are going to rebuild the engine, a few more measurement tools may be needed…But if this job will be limited to replacing the valve-stem seals (is it burning THAT much oil?) you can easily get by with the $25 calipers…A visual inspection of the camshafts will reveal any abnormal wear, no micr…

I can’t see the expense of costly measuring tools being justified for the occasional DIYer. An inexpensive caliper should work fine if measuring valve shims. You might consider buying a set of GO-NO GO feeler gauges for checking valve lash, etc. These blades have steps on them and will tell you ver…

Wha Who? is wrong, it’s easy to buy an accurate gauge from a reputable maker. Mystic, what do you plan to do with it? Are you machining things, or are you wanting to check dimensions?
