Rover 25 Head Gasket Replacement - Oilway Dowel

Hello All,



I'm currently in the process of changing the Cyl Head Gaskegt on my 2003 Rover 25 1.4 Impression. I'm changing it as coolant was routinely being forced out of the header tank. The header tank also had a strong smell of combustion.



So, off came the head, which has since been checked out & skimmed at a local specialist.



The old gasket was in 2 parts. The dowels are also metal.

The new gasket is a 1 piece Victor Reinz affair.



However, in a moment of madness, I decided that I may as well replace the old metal dowels with the new metal dowels in the CHG kit. After little success, I drilled out one of the metal dowels until the remnants could be picked out with pliers .



Unfortunately for me, I drilled the Left Hand oilway dowel [nearest the timing belt]. I'm leaving the Righgt Hand dowel [blind hole] firmly in place.



Of course, this means that a lot of swarf has dropped down into the head / block oilway [all other block apertures were covered during drilling].



Consequently, I've spent hours sucking the debris back out of the oilway via syphon and old hoover attached to flexible pipes. A lot of debris has been removed this way but still finer particles are being removed.



I plan to carry out the following:

1. fill sump wth clean oil through dipstick and drain

2. remove the sump to give it a clean

3. flush eng oil with Wyns additive after allowing engine to minimal warm up on final assembly



Does anyone know if the block oilway leads directly to the oil pump?



Would it be better to also remove the oil pump or is syphoning debris thro' the oilway sufficient?



Ideally, I'd turn the crackshaft on the starter motor to blast all the rubbish out but i really don't want to risk moving the liners with the head removed, even with a liner clamp in place.



Having spent a lot of money getting the head checked & skimmed, etc, + new water pump, timing belt, thermostat, etc, I'd hate for the engine to be toast, though I realise I'll be lucky to get away with this one, not least as the oilways in the head are quite fine & would block easily.



Any advice on how best to process is much appreciated.
