Unless they've recently been replaced, your fundamental problem is probably more basic, i.e. worn out exhaust valve stem seals (and to some extent intakes as well but only if they're very badly worn).
With worn stem seals, excess oil runs down the valve stems into the combustion chambers, which is then burnt at startup making it smoke blue for a few seconds until it burns off. However, the exhaust gas (and excess oil) is also forced out of the top of the valve stem seals (under the spring retainers) and directly into the rocker/valve covers at high pressure, coating everything with said oily crud and carbon, (burnt oil).
Does it smoke blue on startup and at high revs? If not, either
A) I don't believe you.
B) Ignore me and check your plumbing or whatever they said.![]()
