Mayo in my engine

[HandyAndy]

Need some advice please guys............

My engine ( 1.8CVH ) has started getting mayo in the oil, & I don,t know why as nothing has changed recently with the engine

The engine came from my donor which has a genuine 92k on the clock backed up with FSH & old MOT certs, when I installed the engine because it was running so well in the Sierra all I did to it was fit new plugs, new oil (good stuff), new inlet & exhaust gaskets, a new sump gasket purely cos I,ve fitted a shortened sump so fitted new gasket.
The only real engine work I,ve done is fitted new cam followers( all of them) as 1 of them was rattling too much.

The coolant system has new stat, new hoses & a new Rad & i,m not losing any coolant at all,
It gets up to temp nicely & the rad fan kicks in as it should.

I,ve put the correct quantity of oil in as per the Haynes manual as even tho the sump is shortened it also has a "wing" extension so I presume the sump capacity is as per standard.

So, why am I getting Mayo )

This car is determined to live a cosy life just living in the garage

cheers in advance
