I don't really recall there being a washer that goes behind the cam gear in B230F. It's been a while since I've done one.

I can't tell right now from the pics, but that scored bearing surface isn't good. I've seen worse. It may not be the issue. It's a good idea to plastiguage the cam bearing surfaces when you install a cam. I'd also make sure all the oil passages aren't clogged.

Did you measure the valve clearances? I take out the hushers, set the clearances, then install new hushers.

Before you put it all together, I'd spin the aux gear with a power tool and pump oil up to the head and make sure all the bearing surfaces are being fed adequate oil.

If I had to guess what happened here, I'd say the cam gear bolt wasn't torqued well enough when you put it all together.

Some earlier cars had the washer. My 89 740 has one. I remember b23 and b21 engines having them as well.

Yea IPD was stating that the B21 and B23 had the washers and some B230s did. I ordered one but will check all my clearances without and see if it needs it or not. Need to wait till stuff arrives.

You are on the right track. The thing that concerned me when we spoke on the phone was that you said the cam bolt just tightened when you tried to turn the cam clockwise, and then just loosened when you tried turning the cam the other direction.

Even without a roll pin, the cam should be able to be turned clockwise with that bolt pretty easily.

Washer on back side of cam gear? So like Gear > Washer > Camshaft

Never ever seen that....

The washer most likely caused the cam pin failure by not allowing it to sit down properly and caused to much load on too small an area of the pin

Yeah ^^^

I edited my post, but I originally declared there is no washer behind the cam gear, but I thought I've seen one before on old models. I can't remember.

That still doesn't explain why the cam wouldn't turn.

OP told me he put a T cam from a different engine in this head.

The washer is a factory part that was only used on certain B230 engines.

Although IPD says it fits B21/B23 it doesn't appear in the parts catalog for those engines.

Maybe he put the #2 cam cap on backwards and seized the cam?

I opened the picture on a real computer (not a phone) and the bearing damage on #2 looks worse than I thought. The cam bearing surface looks even worse!

You likely have a clearance issue, or a lubrication issue. As I mentioned, Plastiguage is the way to go for a quick clearance check. I put an IPD cam in my head and the rear bearing is wiped and so is the cam, but I put it back together that way and I am still running it like that. :oops: I was in a rush to get it back together and off the rack.

The washer did have a notch for the pin on the cam. The caps were on the correct way. I will check the Plastigauge for the clearence. I have another set of caps from another head.

can you repair the cam? as in replace the pin? Marshall's Hardware on Miramar Rd. should the correct size roll pin for it

Forget checking the clearance it doesn't matter since you can't change it anyways and also forget using caps from the other head... line bored head and caps only work well with their mates.

Just clean up the cam, wire wheel if you have one, and use a green scotch-brite on that cap. Ditch the washer, check valve lash and button it back up

On this old engine, I would just clean it up somehow and then run it. Do NOT use scotchbrite pads.

Check the clearances with plastiguage for good measure, set the valve lash, then make sure the cam spins before putting the belt on. If the clearances are too tight you gotta try another cam, or just get a junkyard head/cam combo that hasn't been tampered with (yeah right)

I think you should be good to go.

Do NOT use caps from a different head.

I have pins in the mail coming and also getting a belt. I have a wire wheel and the green scotch-brite. Do you happen to know the size of the pin? I can pick up one so I can check the valve lash and order any shims that will be needed.
