thats gotta hurt mate, thought the cams guys would of checked with you beforre you picked it up
Mate, that's negligence on the part of the installers. Chase them.
thats pretty shit sue somebody!!!
............
It's not always necessary to do lifters when you do a cam upgrade. The shop who worked on your car may be your problem here. Heard a few horror stories come from there.

they openned my heads up today finally and hit me up with it all. im thinking about seeking legal advice this friday. i asked if i needed to replace push rods, valves anything and they just said valve springs and cam. quick and easy. i will be chasing them for new comp cam lifters and new cam. ill pay the difference for the comp cam over the STD lifters. negligence is 100%, lack of communication. they didnt even tell me to do a clutch with all the work they are going to do on it. its fkn STD and they said yeah that would be a good idea.. after i suggested it. they seem so professional and it seems they know their shit. im starting to think i need to contact a solicitor and either sue for negligence or work a deal out with them. they are installing new performance push rods for free! is it guilt? they even said they feel like dogs for all this happening.
doesnt add up.

Yeah i dont think the lifters are going to be an issue unless they were truely rooted which means whoever put them in isnt qualified and has NFI what they were doing.
Older flat tappet hydraulic lifters found in pushrod v8's and 202's and they like changing them when doing your cam is a bit more of a must of. due to wear on the bottom of the lifter though if you got the skill you can refinish the bottoms and reuse them.

The newer roller lifters arent so much of an issue due to the roller on the bottom
Maybe they Didn't run the cam in properly or check bearings and moly lubed the cam during installation

roller lifters dont need replacing when you do a cam especially low milage VE ones should still be like new

DOD lifters suck balls.
Get some morels and be done with it.
Or at least Comp Lifters.
They should pay for it they stuffed up.
I would be asking to see reciepts or even the goods before they are installed.
They should pay for eveything to fix it IMO as they screwed up.
I would not go in there telling them you will sue, but if they dont come to the party tell them you will take it further.
Performance pushrods are also a must, sounds like they dont know jack shit to me.
You pay for the pushrods they pay for the rest IMO.
Make sure they put new good quality motor oil back in it as well.
All in all it will cost em nearly 1 k in parts, cam lifters and head gaskets etc.
I wouldnt be happy if i was you either.

I would also consider spending the coin and going Comp 921 double valve springs.
If they use the same springs and they are no good expect it to happen again.
Buy them and the Pushrods, make sure the sizing is correct and let them pay for lifters, cam, gaskets and oil etc.
Sounds to me like the springs they have put in have too weak of a spring rate on the valves causing them to bounce off the top of the cam lobes smashing it to pieces.
Thats my advice take it or leave it.

i thought most people took the DOD lifters out when doing cams or can you leave them in

You can leave them in but they dont like much above 6500RPm and wont last much more than 40,000kms with a good cam.

they have enforced the point to me the valve springs installed are over kill. but i will be taking ur advice, and i WILL be stressing to them i dont believe they are strong enough. he mentioned 605 or something like that. no 918 or 921. but like i said they are confident it has nothing to do with the issue. just me red lining to on startup when cold... wankers.

fault with lifters have been diagnosed. holden had a dodgy batch of lifters and i was the unlucky to cop one. it is reported 1 out of every 500 motors have this issue. i was unlucky. Due to the damage on the Cam shaft in a year or two i would have issues so JHP has come to the party and footing the bill for a brand CAM SHAFT, push rods and labour gaskets bolts etc.
