last night:

so there were some b20b cams laying around, and I thought, hell, I'll throw them into my stock 1990 acura integra with 260,000km on it.

now, I know that there really is no difference in lift (measured), and probably not even in duration, but I thought, what the hell, why not?

so, in go the cams, adjusted the valves, check the timing belt and such, everything is fine.

turn it over, starts first time with no issues.

but it does sound like a diesel.

well, whatever, I'll redo the valve adjustment tomorrow.

this morning:

drive about 100km round trip to coach soccer, and just as I get back into town, I notice my car is struggling to idle. hell, struggling to do ANYTHING.

hmm.

towed home, take off the valve cover.. everything.. looks fine.

hmm, metal shavings on the .. no, that would be a groove cut out in a circular shape, on the inside of the valve cover, right where the exhaust cam gear is. hmm..
inspect cam gear, find that it is wobbling around, and untightened.
hmm. take off bolt.

so you know that little nib on the cam that the cam gear slides onto to keep it from spinning?
it falls to the ground.

so, did it seize? iunno.
am I pissed? no.
do I have words of advice? yes.

if someone else has assembled an engine, and you are getting parts from that engine, even if it only has 2000km on it, double check the torque specs.
maybe it wasn't tight, maybe the cam seized. I don't know.

but this sucks.

pictures soon.

 

damm, sorry to hear that

 

well, here we go

<FONT COLOR="royalblue"> How was the car running prior to the stalling?</FONT>

 

it started surging, then sputtering, then not working at all.

 

hmm.... wait a minute that sounds like my car, its doing that right now, hmm im gona have to check that, hope i dont need new cams BTW sorry bout what happend

 

ooooph that sucks....
Hope everything works out for you

 

Well, I can say in all honesty, "Sucks to be you."

 

I'm not totally worried, since there's a b20b head with less than 2000km on it sitting in the garage.

it's just going to be a pain in the ***.

 

You should be fine. Unless you heard the knocking sound of the valves hitting the pistons then you didnt do any damage(given it couldve happened and you just not heard it), but you probably didnt mess anything up(or so you can hope).

 

The cam broke. Put your old ones back in and see how she runs.

 

what were u thinkin of putting those cams in the first place ? I'm not mocking you. I just don't see the purpose

 

I wanted to see if there really was or was not a difference between the b20b and the b18a cams.

I was bored as well.

we've got the old ones in, just going to adjust the valves and throw some oil in and hope for the best.

 

old cams back in, turned over, everything is good.

no headswap for me this month.

 

Glad to hear that it didn't cause any damage.

 

Fun experiment, now be more careful.
