How fubar'd is this cam?

[Eecen]

Its a Schrick, so I'm curious if its still in decent shape. obviously not very hope full though.

All the lobes have similar wearing to this picture, some slightly more, some less. Deepest wear is ~0.5mm at lobe peaks, but you can see where the scratching starts.



I am very sure it is fucked...but just want to be sure.
I mean, it could be run obviously. But how off is the lift/duration going to be?





Pulled from an e21 m20b23 w/ 250k km on odo. Piston 5 was eaten by con-rod, accompanied by a hole in the cylinder wall.

The thing sat for 7 years, then PO "bought" it an drove it into the ground. I picked up the whole car for free, don't worry.

Mail that cam to Oregon Cam and have them duplicate it.

[Eecen]

I emailed them, so we'll see how that goes.

In the mean time I need to figure out what this things specs are.



Anybody have an idea what would have been popular to put in an e21 back in the early-mid '80s? or what schrick was offering for the m20 back then?

There is a raised "933" near the cylinder 5 lobes, and a "SB3" near the cylinder 1 lobes. But schrick doesn't seem to make any m20 cam w/ a P# 933, so wtf...over to an e21 site I guess.

Edit: Schrick 272.

Is this a trick question??

[Eecen]

No? Maybe its hard to see in the picture?

There is a wide groove on the peak of the cam's lobe. The rocker has worn away a good bit of material..I can easily feel the grooves banks with my finger.

ok, now that you've cleared that up, what was your question again?

[Adrian_Visser]

Haha that thing is fucked.

Why do you think that it's anything other than a stock cam anyways?

Pics of destroyed engine don't make me wait until I drive down there.

[Eecen]

Hey, HEY...FUCK YOU :)

It has a SCHRICK imprint on it dude...its a schrick 272/272/111 ($500 new). Give me some credit here, I am not a complete fucking retard..I mean I did post 3 threads asking for help ID'ing the thing; then 5mins later found the P# on it..:(
But I KNOW It isn't the stock cam.

No camera so your gina have to wait till the weekend to see the carnage. but yeah, piston 5 is gone LoL. and piston 2 is flooded.

[Eecen]

ok, now that you've cleared that up, what was your question again?

Well my good sir, I had originally placed a query regarding the merits of the all mighty blumpkin. Ahhhh, such a magical act.

You seem too shy to post your experiences on the matter? I know you enjoy being on the giving side of the act, and that is OK. In fact its more then okay, your great at it, most people get turned off by it, but not you. Oh no, not you.

And hey, remember this is a safe place no one is judging you. No one is thinking less of you. You can speak your mind here.

umm ya, even if it was just 'really' shinny would mean it has excessive wear, and anything with marks/ groves/scraches/ pitting, is toast. get a new one

[Eecen]

Yeah, figured as much..

thanks

[StereoInstaller1]

any news from Oregon Cam yet? Those guys have done about 30 GM cams for me, they kick ass. I am sure you know how SBCs eat cams... theirs last better than any other cam I have used.

[Eecen]

Yeah I got an email from them this morning,

Eecen,

We can copy the profile on your cam and reproduce it on a used cam. I do not have any BMW new castings. I don't know how much smaller the base circle will be without having the parts in hand to do so. Was your cam a new one or a reground cam to start with? The cost to regrind your cores to the performance grind is $99. With five or more at a time we give you a ten percent discount.

Thanks

Ken

I haven't replied yet.

i need to get my hands on some used m20 cams...or see if they're willing to buy some new castings, and ask what the cost increase would be.

Are they better then Delta cams in Tacoma? Can they do regrinds on M50 cams?

I have no clue, but that would be good to know. They are in Vancouver WA
