it could be of your mech. mixed al the shim and not installed it according to their original arrangement because shim might have different thickness according to the shim bucket+camshaft clearance.. :adore::

I think we have discussed about this typewriter/diesel sound on 20V engines before. Most likely it is due to the VVT intake cam pulley that's causing the sound. Replacing with a new VVT cam pulley should resolve this issue (personally worked for me).

Good luck!

we dont have this with the 4e, lol

personally, i think the shims clearance shudnt be dat obvious, imo its down to the quality of oil dat u r using. what oil do u use sir?

iam using a mere 4g91, and i think everybody knows how dis engine TICKS; like a mesin jahit yo!!!! what i found was, it only ticks when iam using certain oil jer, and certain brands keeps it quiet. total is one of the expensive oil dat kept it quiet, but i cudnt afford to maintain dis brand, so went to sum other brands instead. i hope dis helps sir

please check the pcv sir, its a valve on totp of the cam cover, if ur engine is in good condition and not consuming oil, no leak anywhere in the bay, then dats the only possible way to experience oil loss. its just a cheap replacement jer tu..

10w-40 is a good choice for dat mileage sir, whereas 20-50 may be too thick for ur application. the thicker oil may solve ur problem, but i wud suggest u check all other possibilities of the oil loss before changing to a thicker oil as it may not be necessary

from wikipedia - A plugged or malfunctioning PCV system will eventually damage an engine. better change my PCV,, how much cost to change PCV,,,

Totally agreed with ^pomen_GTR^
not all mech can do 20V engine...

please ask the mech to check again the engine.
He should able to fix it...if not...

you could pay a visit to any known 20V experience mech...

after changing the valve seal...you should got any issue with engine oil lost...
unless your piston ring is torn already...if do your mech should informed you...
