Cooling fans ,mounting . Experience teaches me that those pull thu plastic clips can cause excessive wear to radiator core . Fans 15amp minimum or better get the 20amp SPAL =max air flow . Sizing can be either blade or housing diameter . 2x 12 inch or larger 20 amp each ideal . Even if when mounted on puller side they overhang core by around 30mm per side . Have a shroud made up to suit .
My neighbour's 308 had aftermarket rocker covers fitted, and, somehow, the PCV system stopped working. He had the covers modified, and it cured the overpressurisation in the crankcase. Quite what was done, you'd have to ask him, but he thought he was in for a new engine. It's been fine for 18 months now.
My dad gas axed his old 1972 model HQ Holden Kingswood wagon back in the late 1990's because it was full of rust,it only ran the 202 cubic inch 6 cylinder engine but the last engine was a 208 cubic inch engine AFAIK because it had heaps of compression & it went well for a 202 engine. I don't think that there's much wrong with the engine rather that maybe the breather hose to the top of the carburettor can be teed between the 2 valve rocker covers. A cylinder leakdown test will determine if it's excessive piston ring clearance which is causing the crankcase to get over pressurised !
HQ have an open PCV system ,, Late Hj have a closed Pcv system open air enters engine via a mesh breather travels thru engine exits via PCV valve vapours get sucked into manifold closed air enters engine valve cover from factory air cleaner [ hose ] [has a mesh filter inside aircleaner ] travels thru engine exits out pcv vapours get sucked into manifold ***** inside valve cover there must be a shield that prevents oil splash directly on to PCV . This will give high oil consumption
got a noisy lifter & rust in door..
Straight to the crusher🤣

Mine seems cured for now see how it goes
love the sound

Fixed it runs like a top now
wow nice👍🤩
HQ have an open PCV system ,, Late Hj have a closed Pcv system
open
air enters engine via a mesh breather
travels thru engine
exits via PCV valve
vapours get sucked into manifold
closed
air enters engine valve cover from factory air cleaner [ hose ] [has a mesh filter inside aircleaner ]
travels thru engine
exits out pcv
vapours get sucked into manifold
***** inside valve cover there must be a shield that prevents oil splash directly on to PCV . This will give high oil consumption
put the 202 back in.
how did it pass with no fkn wipers hooked up.. washer.. block..
Wipers work. Man so does the washers 🤣
you need an oil filler cap thats not sealed like that one,the old mesh type is what it should have being hq not sealed.
