You don't have a cheapo dial guage lying around somewhere?
Maybe a $40 clamp-on unit from your local Harbor Frieght?
Clamping Dial Indicator
Amazing deals on this Clamping Dial Indicator at Harbor Freight. Quality tools & low prices.
Zero it on the base, rotate to the tip, and there you are.
Great idea. Ill pick one up. I need one for the rebuild Im doing on my Peugeot so will get back to you. Do you have the specs on hand I need to measure it against?You don't have a cheapo dial guage lying around somewhere?

Measure it with calipers. subtract the base circle measurement from the lobe height. Done.
OEM cams are pretty tough. If you can feel a small drop off either side of the cam lobe you know it has some life left in it yet. If it's one unifrom height the cam lobe has worn some.

Do red blocks with OHC benefit from a zinc additive to the oil?
Thanks for the heads up. Sadly I left all my tools in Australia when I moved here a few years ago. Luckily I found my $100 voucher for HF and bought both calipers and dial gauge this morning! I will report back this morning with figures.

Likely in the top of the pic I posted... .390" and .390"
Thank you. Missed that bit!
Inlet clarences
1 = .015
2= .018
3= .015
4= .016
Exhaust
1= .015
2= .014
3= .016
4= .014
They all seem fairly good. It does sound very quiet when cold and gets a little more ‘noisy’ when oils up to temp. Ive had 2 volvos previously and its seems consistent in terms of valve train noise.
Lobe measurements to come soon.

Yes. Most of us run diesel oils. 15w40 works great in the warmer months.
Lobes all measure at 390 or above on my new (cheap) dial gauge. So Im happy with that. In person the tip of the lobes do have some layers showing but its very minimal.
Maybe Im trying to find problems to upgrade the cam! Thanks everyone for the help. Its been a good exercise.

Yes, start the upgrades with a cam. An IPD turbo cam is a good fun upgrade even with an auto.
