    Default VK 308 Engine Build and bay tidy up - when you start out to fix an oil leak then.....

    Hi All
    Just thought I'd share on my first build. It started out as fixing a rope rear main that was p1ssing oil and annoying me, but I kinda always knew it would turn into me doing a freshen up on the engine. The problem now is where to stop.

    My criteria was to keep it looking factory and to retain the original heads, intake manifold and quaddy - try and keep the original look. So I just want a strong reliable old donk that can rev a bit and sound OK, if not to actually outperform a bog stock VW Golf at the lights that would leave me standing, but to at least intimidate a little with a good rumble .

    The engine had signs of gaskets being changed, a new timing cover and water pump, but otherwise I knew nothing else. It didn’t sound anything special and would run out of rev’s at about 5,500 with a few funny noises – so it would always make me lift off.

    Anyway, the engine was running perfectly fine and had just spent a track day at Sandown and some backroad thrashing before I ripped it out, so was quite surprised to see the internals we in pretty good shape, maybe except for the timing chain.

    So anyway, my story is that it’s hard to just “build and engine” to a budget without hemorrhaging $$ just on the engine alone. Then it’s hardly worth neglecting the engine bay while the engine is out, so then more $$ start to disappear…

    Like many, I’m doing it all single handed apart from the machining etc, which gives some satisfaction that you’ve done it by yourself (plus read pages and pages of other peoples builds and woes!).
    Here goes.

    pics are there....

    ps you are killing your hp by sucking in hot air from the engine !

    GMH put a cold air snorkel on the engine for performance purposes...
    and you lift the top of the air cleaner up... and allow hot air to be sucked in

    Thank's Smitty for both things. The engine as pictured is 100% how I bought it, the air cleaner element is taller than factory - I think is like that more for the induction noise that HP . When i was a boy 25 years ago, we used to do things like that too!
    Anyway, it will go back to standard.

    Engine out and strip down. I was interested to find what was inside after 30+ years.
    No real sludge, was pretty clean.
    Std size bores and slugs.
    The cam and lifters looked OK (no lobes missing), so I think had been replaced at some stage,slight dishing on the lifters, but anyway they are getting binned.
    Double row timing chain that was as loose as my old BMX bike chain - you know that loose that when you stood up on the pedals to crank it would slip off and you'd smash your nuts on the goose neck.

    Main bearings had a sate stamp of '85 and big ends '97. Both were standard size, but obviously it had been touched up at some stage.

    Maybe a mild 355 stroker?
    Keep your original Inlet manifold, carby and heads. I知 guessing they are B cast heads, get them reco壇 bit of a tickle I the ports to flow better. Would make a great street car with good manners whilst sounding tuff and making some extra HP and torque.

    I知 looking forward to your build.

    Hey 46Crab - I'm just going for mild 308, budget stopped me looking at stroker kits, even though there are some cheap parts popping up due to people doing LS builds. I'll be happy for a nice sounding 308.

    Here's the culprit...


    Quick cleanup while the cook is out shopping.


    Anyone know or recognise the markings on this cam?

    VKSS69..... I知 loving the parts in the dishwasher mate, farking pisser....

    With your budget 308, are you going to bore and hone it at least? I知 guessing not by the pistons and rods getting a wash in the dishwasher??
    I知 still pissing myself about that, love it.

    Lol, the second load was the valve gear and bolts - works a treat - just don't let the cook find out. I just wanted to clean everything up, but yes will be replacing pistons etc.

    So my budget build is trying to build it to a number, not scrimp, but then not go crazy on stuff. I want to keep the B cast heads, manifold and quaddy, so I am limited to what it will flow etc.

    Heads will be touched up a bit.

    Everything will be machined and balanced. Block bored 20 thou over and TP honed, line bored, decked and squared etc - you know kind of standard machining stuff while it's apart.

    I picked up some A9L rods and Street Terra roller rockers, sticking with hydraulic flat tappet cam, new cam, lifters, valves, guides, beehive springs.

    I want it to be strong and have some fun with, without worrying if it will go bang when i rev it.

    I'm going to do the mains oiling mod that's been talked about on here and by COME about blocking the #4 cam bearing lifter gallery feed and drilling the new feed behind the #1 cam bearing. I don't know if it works, or if i need it, but while its all apart I'm going to give it a go.

    So I got busy with a die grinder and burr removing some casting flash for the oil drain back - again don't know if I need it, but feel better knowing I've done it.

    If your going to bore the block and get everything balanced you may as well stroke it. Vpw sell scat holden journal cranks for $435 (wait when they do they their ebay sales and you could score one for $340 like i did) since you got a9l rods and you need new pistons anyways the only real expense will be the $400 for the crank and the little bit of time on a die grinder clearancing. Bang for buck it will be the best thing you could do for the build. Im in a sililar situation as you with my vk build was originaly going to do a rewire in the bay now the whole car has been gutted, doing full rewire, aftermarket a/c install, pissing off grp3 kit and building a 355 w/6speed conversion.... by the way i love the dish washer idea

    So the block, crank, heads, rotating bits are at the machinist getting bored, line honed, balanced etc. The B cast heads are getting new valves, guides, seals and springs. The short turn radius has been touched up a bit for flow and a 2 angle seat cut for the valves and seats.

    I wanted to keep the 955 intake manifold and it needed some welding to get rid of some corrosion to prolong it's life.

    While the engine is off getting done, the engine bay was pretty shabby, so I begrudgingly started the process of stripping it and prepping for a new coat of 2 pack paint. It's a long process, but here are some before and after pics.
