Block the 2 coolant ports on the top of the LIM (yellow O rings), either weld or tap and plug (1/4" NPT). Than you can remove the blower in the future without needing to drop the coolant. Whilst the heads are away, have them check the valve springs installed height, and full lift etc to make sure you have enough available valve lift for the cam as stock heads are only good for about .520" lift and your cam has much more.

[@MrDOHC1JZ]

Back when I worked at a large engine building place. At least 50% of the heads we took off the V6s were binned due to cracks. Only if we couldn’t get spares would they repair them.

[@bugproductions9050]

Proof that "crack" is bad. That is all.

Whats the common reason they crack so often?

I remember changing the head on the hj45 and the "replacement head" had 12 cracks in it before I got it half way out of the packaging. The skippy badged head I put on it 12 years ago is still doing it after some HUGE petrol radiator drama... The hj47 radiator has stopped the #4 pot combustion chamber from beading... The new heads will be good. So worth it!

Scotty mate you should have the mechanic's trolley set up with small plastic containers labeled so you have every important items taken off put in the right place, so that when it comes time to put everything back together you have not lost anything, my friend did this and had a 9 second White HR ute NO Plate was SWAN 01 and he built the engine himself, sure got everything from performance aftermarket items, but still done well and this was back in the 1980's? I told him to go auto from a top loader and he dropped a 1.5 second just from 4 speed to auto, also no turbo just straight out engine performance?

And of course the L67 used different heads to the L36 so you can't just go to any junk yard and source what is required.

Fingers crossed you get a hold of a decent set of heads .... L67 heads loved cracking between the valves 😣

Sorry to hear about what's happened to your Supermang VN Commodore unfortunately these things do happen surprises to happen so it does take a little bit longer for things that we want

[@vortex925]

I called it from the announcement of this project that supermang would go superbang, its not that you did a bad job but those L67 are a base Buick motor which runs okay na but had many weak points which surface quickly when boost is added. There no barra and need alot of supporting mods to make and keep them happy but then again once road kill became country restricted carnage filled that slot quite well right down to the consistent problem but a bonus like mcm is aussie content.

[@dazaspc]

MMM last time I pulled a Commodore V6 with a cam and a broken chain it cracked the ring grove at the top of the piston. Scotty just pull the dented piston to check block in car. You have a hoist. High load and boost top rings never ever seize and take out chunks of piston. Do they?

[@STREETMACHINETV]

The more I think about it, I might just pull the bottom end and do another. Swap the cam from this one to that one.

[@dazaspc]

@@STREETMACHINETV Might as well just put in a Forged bottom end with the appropriate ring gap. Far less messing around when turbo time comes around.

[@STREETMACHINETV]

@@dazaspc the idea was to see how we could do on a standard bottom end

[@MrGofkurslf]

Are you guys doing an a2a or a2w intercooler? I just had an l67 built and I'm doing a a2w set up. Shit loads less cooler piping work needed, and been proven over and over to be way more efficient with intake temps. Its just a little more wiring for the water pump and fan/s (don't need to run fans but it always helps) My mate was actually talking to one of you guys about a start up tune for my build for the haltech

[@zackriley4577]

Scotty, have a spare set of l67 heads, I believe they are off a 2002 calis or xu6

Flicked you a photo on instagram

[@STREETMACHINETV]

I'll check it out, thanks

[@SuperTambo69]

Hi scotty will you need to work out piston to valve clearance again? I reckon timing chain broke cause of the valves hitting, putting strain on chain.

[@STREETMACHINETV]

If valves were hitting every piston would have marks

[@LockieNZ]

Shocking that a chain like that failed so quickly. It looks way beefier than what they use in a Barra. First time I saw a Barra chain, I though someone just pulled it from some kids 10 speed!

[@davidwindsor4632]

Is it worth while doing a strong bottom end with new rods and pistons. While down and bearings. 🤔🤔👍

[@joelfrancis5391]

Silver lining mate she will be even more of a beast now!

[@BrosefDudley]

L67: costs twice as much money to make half as much power as an XR6 turbo and still bends valves, cracks heads and breaks timing chains.

This is a good lesson to those who want to upgrade their V6. Chuck it in the rubbish receptacle and do something else, an LS conversion would be cheaper and more reliable, probably weigh less.

[@ytthecommunistplatform.2675]

Dont forget to regap the rings or you WILL rip the tops off . When you put the cooler in and the silicone bends you need to slide a metal bend inside the silicone pipes because they suck in under vacuum . My friend leon owns awesome auto in adelaide and is the gm guru on the v6 engines and knows all the ins and outs of all gm software and engines . Go ring him up for advice if you want . You really should have gone for a water to air cooler instead . The air to air suffers from heat soak . They put out good hp but do have trouble . Get intouch with zz performance in the states and try to get a set of their alloy heads if they still have them . Go hard or go home i say . You really should change the pistons because they are shit stock . I uesd engine tech ones from the states or go some je forged pistons but they are pricey though .
