Instant Death

HKS cam gears do not have enough adjustment to smash the valves...

i have one on my RB25det and when i first put it on i didnt do it tight enough. after a month or so it slipped right ot the extreem and while the motor had less power it certianly did not smash vales or anything like that...

Shhh! don't tell people that. They won't be able to bash HKS products anymore

You cant argue though the HKS series one gears were decent.

The marterial was shit and the teeth wore down over time therefore making the Gen 1 gears the worst of the lot

bummer. my advice for ANYONE who fits ANY BRAND of cams gears is to check them 4 weeks after installation. being alloy there is always some 'give' in them. you tighten the bolts on installation but they can and do come loose. on one of my 32 GTRs. big build in japan. brand new crate motor, fully built from new, HKS turbos, 600ps all the good gear, cams, springs, head work blah blah blah. about 2 months after it was built we checked the cam gears. sure enough the bolts had loosened off. and these were tomei gears which run 5 bolts (i only use the 5 bolt jap gears, either tomei or trust). well worth checking.

Or just use stock modified gears

Were they HKS cam gears? Contrary to popular belief, not everything HKS puts out is even half way decent. I have seen their cam gears kill 2 motors. They only have 3 little bolts holding them in place. Really need to crank them little buggers down.

yeah, they really dont have a very god track record.... i went greddy because of this

I don't know what to tell you. I have seen two motors with bent valves that had an HKS cam gear which had slipped all the way to max adjustment. I doubt it was tuned that way and just a coincidence.

And HKS is really good at one thing with their parts. Adevertising. Nevermind, two things. Advertising and over charging for rebadging other peoples products.

bent valves. the pther problem i've seen with HKS cam gears is that shiny blue shit wears down/chips off, resulting in a tooth half the size of what it should be.

at this point, i'd guess its jumped a tooth (loss of power) then jumped another tooth and smashed valves.

iv seen a rb26 on a dyno run with cam gear loose, didnt bend the valves.

I don't know why we are still discussing causes. the only way to suddenly get no compression everywhere is stuffed valves.

But you forgot the other very plausable option, some one stole his pistons.

[Duncan]

lol very true....

maybe the gnomes that keep making hammering noises in my bottom end jump into his motor and took them

[TiTAN]

got a 12cyl engine now duncan?

[toffy]

have you actually checked the cam gears to see if one(or both) hasn't slipped holding the valves open at the wrong time? (its late i cbf being technical)

Or a stuffed compression guage.

now we are getting some where, they stole his pistons and rods so they could do band practice in your sump.

This one time, at band camp............

Stop being silly.

You can't have band practice without the lead guitarist and that would mean his turbo would be f**ked too.

[**RB2530**]

I would try turning the engine over by hand. You will very quickly confirm if it does have comp or the comp tester is RS.

[The Mafia]

mate, did you ever find out what was wrong?

[Beer Baron]

yeah I'm curious to know too.

[GTScotT]

lol a year later lets hear it

unless he tried to fix it before the wedding.... and... did not.. make it..

[FLN75S]

Gee i remember origanally reading this i would be keen to know too???

My money is on bent valves
