Hi folks I remove all of these plugs then drill and tap for allen brass plugs. For the main reason of cleaning the oil gallery properly on rebuild as 98% of rebuilders don`t do it and leave loads of gunk, swarfs and all inside the galleries. Upon first start up, all that junk gets pushed into...

Hi :P There might be a blockage on the oil gallery for that rocker arm, so no oil is going to the tip. It`s quite common on older engines or in engines that used low quality oil or even on engines that don`t run a lot and don`t get to normal operating temperature very often, therefore creating...

Very critical point here. Deck height A tight deck is essential for an efficient engine, also for a cool running one. A deck of between 1-1.5mm is what you want, i like the 1.1-1.2mm area for most engines. An engine with a greater deck will use more fuel and run hotter, due to the combustion...

Adjusting ring gaps and also balancing pistons A quick note; the AA pistons comes very well balanced from factory. If you just play with the pins, you can get a balancing of less than 0.5gr. ;)

Ozzie, you are amazing, i can`t stop laughing :lol: :lol: :lol: Glad to be here again.. i`ve been too busy with loads of things; divorce mainly.. but all sorte :roll: d now Please call me whenever you need help mate, that`s what friends are for, anytime, just shout ;) Take care my friend...

Hey Ozzie, how are you my friend?? :D

:party0049: I love the AA 500 heads. They are made of a decent easily machineable alloy, have loads of cooling passages just like the OEM, uses a long reach spark plug, have a modern heart shaped combustion chamber for an efficient combustion, have a solid chunk of material around the combustion...

:D I like the endfloat between 0.08-0.09mm. Perfect

Getting ready to close the halves after a few mock ups :mrgreen:

Scat C25 cam, great upgrade from stock; idle like stock with twin carbs, loads of down low torque :msn4: Gen VW cam gear Schadek 26mm oil pump being checked for clearance on the cam bolts; it needed clearancing :lol: The pump was then pinned again. Also plugged for full flow and blueprinted...

Crank plugs get Loctited Rods are balanced within 0.1g :D

The flimsy Brazilian oil pick up tube is removed by drilling the alu plug, then a precise tool pushes the tube out. I then get a German tube, seal it, tap the gallery and plug it. That connection between the tube and case is very critical, as if the oil level is low, the pump will suck air and...

Case is machined for 90.5mm barrels. I do it step bored so it only removes material in the needed areas, leaving the case stronger. I also spot face every single case saver to avoid the barrels sitting on it. Internally, all sharp edges are removed, and hand clearanced for the stroker crank...

Here we have the crank with Gen VW shot peened gears on, the forged flywheel and the Kennedy pp all balanced. Crank was very good, the Kennedy too but the flywheel was way off. It was supposedly a balanced from factory unit that costs around £200 :roll:
