He blew it up

No, I didn't "blow it up". I had a soft cam, lost four lobes on it. The rest of the motor is fine.

It is was it is bro, not that YOU would know any different. lol

[wezeles]

whats with all these bad cam's first matt now you... i think im gonna toss any cam i get in the oven just to be safe from now on... wow

Mine was a CWC casting which has had issues for being soft. Wish I would have known that when I got it

Also...I read some interesting articles on todays motor oils. Oils that are produced today really don't have the high pressure additives that engines with flat tappets need. The reason being is that major engine manufacturers do not make make flat tappet motors anymore. It's best to run an oil with these additives or buy them and put them in. GM's EOS is one of the better ones I have heard about.

That's interesting, nice they just said F*** the older vehicles still on the road. I'll keep that in mind when I do get around to building a motor for my 80 Z28.

well when you look at newer motors most are OHC or roller motors so they are more worried about the bearings staying conditioned then they are keeping the wear element away... some of the best oil ive used is the eurpoean blends alot of the new oils did away with zinc and other additives that help with the life of an older motor.. unless its an aftermarket like royal purple or lucas made for high perfomance that have the additives then i try to buy the european blends, alteast they still have the standards that include the additives...

[WMCCjames]

OT...yeah, just be carefull what oil you use in your older flat tappet motor. I was actually using mobil 1......not sure if that help lead to the destruction of the cam lobes also.

[wezeles]

thats a big argument between people using the syn on an older engine.. i always use standard oil till i know its running healthy then switch to syn or syn blend after that... if it does have something wrong... like a bad cam..lol you dont want it to wear out with the raw efficiency that synthetic will give ya ha ha... not sure if it would make it worse or better in that case

[WMCCjames]

I scored a barely used set of Hawks stainless LT's and y-pipe for the conversion!!! Got a killer deal!

Soft cam, spun bearing, threw a rod, dumped the oil pump, whatever it was, stopped working, died. "blew up"

That's all I meant.

you can run a car on a "almost" wipped out cam my mech ruined his in the 280z someone ripped the plastic bag covering the carb off and rain got into the intake he never cleaned it out and ran it with water inside it... some how got into the oil too through the breather in the air filter... we poped off the intake only 3 out of the 16 lifters even would turn around "flat tappet" and then half the others didnt seem to move much at all... he drove it another 2 months like that ran like crap but it ran... i guess a 580 lift cam halfway worn out is still good enough.. lol

[WMCCjames]

Well, there was no more running mine....it was popping and rattling like a mofo. I hope I never hear that sound again.....at least on any motor I own
