Compcams link bar lifters?

94IVGT · Mar 28, 2009

So I put the compcams link bar lifters in my dart build last winter and had some valvetrain issues along the way. And my conclusion was I had 2 bad lifters. Well I pull the heads off today to get them out and it seems that inside the lifter above the spring and piston, the little metal peice that should be in there holding the cup/piston in the lifter body had been bent and pushed out of 4 of them. Has anyone had issues like this before with these lifters?

Damn, that's really weird. I'd call comp about it on Monday. I'd like to see some pics too.

94IVGT · Mar 29, 2009

i will get pics today, and most definately looking forward to that phonecall.

Absolutely...I would def call comp.

Just curious, why didn't you just use stock lifters? As long as your using a hydraulic roller...stock lifter are more than sufficient.

Fwiw...NMRA renegade class has to use stock unmodified lifters and those engines see 8000 rpm's and well over 1000RWHP.

I heard rumors they were "modifying" those lifters to make them survive that kind of abuse. I don't know the details, and of course it could be all speculation and heresay, but given that those guys are pretty serious - I wouldn't doubt it if a little "ingenuity" was involved. :grin:

I am SURE nothing is ever 100% honest with competition like that lol

BUT...the stock lifters can take some serious abuse.

Paul · Mar 29, 2009

I agree. My 422 has OEM lifters in it.

94IVGT · Mar 30, 2009

well i had switched the stockers for the link bars on the dart motor because i had a stocker get loose(get out of the dog bone bracket) in my last motor and it turned and ate my cam up. So with a 10g motor i didnt want to take any chances

LAFENATU · Mar 30, 2009

Sounds like a good enough reason to me..

So what was the results with comp? Did you get a chance to call?

94IVGT · Mar 30, 2009

Well i gave my engine builder a call today and he hasnt seen this issue before but told me to send them to him, he is going to see what may have caused them and then take it up with comp for me. sorry about not having pics yet, ill try and get them soon.

94IVGT · Apr 1, 2009

still no pics, having a little issue finding the camera but will get them

AfghaniBob · Apr 2, 2009

well that isn't cool.

Engine builder = Brian? If so let me konw who well he takes care of this. Also not too comforting since I don't have but a few miles on mine with the comp tie bars in them also.

94IVGT · Apr 2, 2009

Yes it is brian, been a long time since ive heard from you afghani. You will be the first to know what happens since you got the same build as me from the same guy. but he seemed cool about it but we will see what happens. camera found by the way and pics will be up tomarro fo sho

AfghaniBob · Apr 3, 2009

Yep that be me still here in the A-F-G

I finally get to put some miles on my motor in about 7 days. It has had 13 put on it since I left in August. My goal is to put about 200 miles on it and then drop it off for the turbo install. (I will update my build thread with some pics as soon as I get home next week)

How long is yours going to be down for?

94IVGT · Apr 3, 2009

Thats awesome man, well my goal is May 3rd for the JCWhitney Car show. But with the lifter issue and D+D dicking me around on this bad clutch for the last month idk.

Please tell me you do not have a zoom twin disc going bad?

Chitty thing is I told them to sell me the best twin disc they had and they sold me the second best that may not handle the power.

I have a McLeod twin-disc I can sell you - it'll hold the power just fine. :grin:

Paul...

How many parts do you have for sale lol? People talk about parts and then all the sudden Paul flys below the radar and all the sudden..

I got whatever for sale...

LOL..

94IVGT · Apr 3, 2009

no i didnt get the twin disc setup like i wanted, they told me that the C174 zoom 3.5 would support 700hp so thats what i got and 800 miles later it had to be pulled out cause it was slipping real bad. and i talked to them a little last year let them know what was up and talked to them 2 months ago when i brought it out of storage and the guy there wont say names yet but he told me to send it back up there and he would take care of it and get me another one sent out. and now its been a month and i call once a week and all i get is the run around. bunch of bs, especially after droppin 6gs with them.
